How to disassemble the split system indoor unit samsung. How to disassemble the air conditioner? How to independently disassemble a household split system and clean it? Dismantling of industrial air conditioners

For efficient and safe operation of the air conditioner, regular cleaning of the internal elements of the system is required, and in addition to the external one, it is imperative to disassemble and clean the indoor unit. Most often, in offices, apartments and private houses, wall-mounted SPLIT devices are installed, presented by different manufacturers and modifications. Considering the demand and popularity of climate technology, many people will probably be interested in learning how to disassemble the indoor unit of a wall-mounted air conditioner in order to be able to do it themselves.

Design features of the indoor unit

Wall-mounted split systems by LG and others, which include Daikin, Mitsubishi, Toshiba, Fujitsu, Ballu, Samsung and Hitachi, have a similar design of the indoor module. Thanks to this, if you know the basic principles of disassembling the air conditioner, each owner can easily cope with such a task on his own, only for this you should identify the main components and parts that make up such a unit:

Standard design of wall mounted air conditioner

  1. Front (front) panel
  2. Coarse filter
  3. Fine filter
  4. Fan
  5. Evaporator
  6. Horizontal blinds
  7. Display panel
  8. Vertical blinds

You need to understand that proper disassembly consists in following a certain sequence of actions that allow you to gradually get to those elements that need to be cleaned. Only careful dismantling can eliminate the risk of breakage of internal components and modules, so you should act carefully, without applying excessive physical effort. Of the tools, several curly (phillips) and straight (flat) screwdrivers of various sizes are needed, as well as several hex stars.

Before dismantling, make sure that the air conditioner is turned off from the mains! This is very important to avoid electric shock.

Dismantling the indoor unit of the wall-mounted air conditioner

They begin to disassemble the air conditioner by removing the front plastic panel, which can be attached using clip elements (LG) or bolts (Toshiba), depending on the manufacturer. In the first case, you need to use a straight screwdriver and pry off the clips located above and below, and in the second, use the appropriate tool. The next step is to remove the mesh filter (coarse cleaning) and plastic shutters from the indoor unit, which are simply removed from the corresponding slots.

Strainer that needs to be cleaned

Next, you should carefully dismantle the drainage system of the indoor unit of the air conditioner, which is usually made in the form of a tray. In some models, it can be made integral with the body and removed only with it. Before removing it, prepare a container or container in advance to remove condensation formation. To detach the tray in LG models, you need to unscrew one bolt and snap off the clips located at the bottom.

Fan/impeller removal options

Next, you need to remove the fan of the indoor unit of the SPLIT system, made in the form of a shaft. This will require very careful and responsible work, since it is important not to damage the internal components and components of the air conditioner.

Removing the strainer

There are two ways to pull out the shaft:

  1. A simplified version, in which it is not necessary to perform operations with the electric motor and control unit (the shaft is pulled out from below). Usually it is he who is chosen when doing the work with his own hands, which requires less time and effort. Here the sequence of operations is as follows:
  • We unscrew the bolts / screws and release the radiator on the left side of the main main body of the SPLIT system
  • Gently loosen the fastener on the right, where you need to carefully unscrew the screw on the shaft itself (as a rule, it is tightened very tightly, so you need to act carefully and slowly so as not to twist the fastener head)
  • Carefully remove the shaft component from the housing, and from under the bottom, making sure not to damage the blades (holding the screw with a screwdriver)

Important! In the reverse assembly (mounting) sequence, the fan mounting screw must be in the position where it was originally, since otherwise there is a high risk of contact between the fan blades and the walls of the indoor unit.

  1. A more complicated option is when the shaft is dismantled on the right side, for which the control unit and electric motor are removed. To perform the operation, proceed as follows:
  • We disconnect the wiring and electronic type sensors from the control unit, snap off the fastening clips (in some models we unscrew the fastening screws) and carefully remove the unit
  • We unscrew the fastening elements of the electric motor, disconnect the shaft from the casing
  • Very carefully and carefully, with slow movements, disconnect the shaft from the motor, and also bend the radiator tubes

When performing work, it is important to remember all the manipulations in order to assemble everything correctly after performing the service of the SPLIT installation.

What needs cleaning?

After performing these manipulations, you can start cleaning the internal components, and here it is imperative to remove dirt deposits from the rotor and evaporator, using antibacterial compounds (active foam), clean water and steam (steam generator tool) for this. The condensate receiving bath is also cleaned of dirt, after which all parts are thoroughly dried. In addition, it will not be superfluous to lubricate all moving parts with silicone grease, which will extend their service life.

To disassemble the indoor unit of the air conditioner, you need to be patient, act carefully and slowly. It is always important to remember that the SPLIT system has a complex structure, where all the internal components are very close to each other. This instruction gives a sequence of actions that are performed regardless of the design features of the wall-mounted climate control equipment.

During the operation of a household split system, you can smell the unpleasant smell of rot along with air flows from the device. It indicates the need for preventive cleaning of the unit. In addition to repulsive amber, clogging of nodes can cause rapid wear of the power unit, increased power consumption and the occurrence of allergic reactions in humans.

You can entrust this procedure to a service center employee. But if you have been using a split system for a long time, you can handle the work yourself, saving money. It is only necessary to familiarize yourself with the procedure for disassembly and preventive cleaning.

Indoor unit dimensions

Before installing the indoor unit of the air conditioner, you should take an interest in its dimensions. This is especially important during repairs, because modern technologies quite often involve the installation of suspended ceiling systems, which can affect the height of the ceiling, as well as the parameters of the described device.

On sale you can find non-standard models that have unique sizes. The length of the block usually varies from 700 to 800 mm. Products up to 900 mm are somewhat less common. Experts recommend taking into account an average length of 770 mm.

As for the height, it is usually equal to 250-290 mm. The average value is 270 mm. Depth is not of great interest to consumers, but it reaches 240 mm. The minimum value is equivalent to 170 mm. From this we can conclude that the average dimensions of the indoor unit of the air conditioner are 770 x 270 mm.

Knowing these parameters allows you to determine at what distance from the ceiling and walls to hang equipment. There are a lot of controversies on this issue. In some instructions, the minimum distance is 50 mm, while in others it goes up to 300 mm. The optimal value is equal to a figure from 60 to 150 mm.

Specialists usually install air conditioning with a distance of 100 mm. Before installing the indoor unit of the air conditioner, it is important to consider whether there will be curtains in the room. The step between them and the split system is usually 150 mm. You can increase this value up to 250 mm. The average distance from the block to the wall is 400 mm.

Classification of indoor units

In order to carry out disassembly, it is necessary to determine the type of the indoor unit of the air conditioner, which can be represented:

  • wall split system;
  • channel air conditioner;
  • cassette device.

The most common are wall-mounted models, which are more affordable and are sometimes also called household ones. Their installation can be carried out in a room for any purpose, and the power within 7 kW allows you to cool up to 70 m2 of area. Such blocks are usually installed in the upper part of the wall, not far from the window, since the design provides for the presence of an outdoor unit, and the nodes must be interconnected.

Wall-mounted air conditioners are not able to supply fresh air to the premises, as this requires a separate ventilation system. If you wondered how to disassemble the indoor unit of the air conditioner, you can read this information below. It is for such a device that the recommendations in the article are given.

In addition to household air conditioners, some manufacturers supply semi-industrial devices to the market, the power of which reaches 10 kW. Outwardly, they look like traditional split systems, but in terms of parameters they are semi-industrial equipment.

Ducted air conditioners are installed with suspended ceilings that hide them completely. The distribution of cooled air is provided by heat-insulated air ducts, which are located in the interceiling space. Such structures can cool several rooms at once. The power of the equipment reaches 25 kW, which makes it possible to provide cooling for a cottage or several rooms of an apartment. The main feature of duct systems is the possibility of supplying fresh air in the volume that is guaranteed by the functioning of full ventilation.

Cassette air conditioners require a false ceiling during installation. When compared to duct designs, cassettes distribute cooled air through the bottom of the unit. It is closed with a decorative grill and usually has the following dimensions: 600 x 600 and 1200 x 600 mm.

Dismantling and cleaning the air conditioner

To clean the indoor unit of the air conditioner, it is necessary to disassemble it. For this, screwdrivers of various configurations and sizes are prepared. You should take care of the presence of a box for collecting fasteners. You will need electrical and functional diagrams of the device. In some models, they are printed on the inside of the top cover.

To clean the internal elements you will need:

  • clean rag;
  • detergent;
  • a vacuum cleaner.

The first step is to de-energize the air conditioner. This is in accordance with electrical safety regulations. Remove the plug from the socket. The top cover of the block is removed. Bolts are unscrewed, which can be two or three. Usually they are closed with decorative caps. The top cover of the indoor unit is removed. If it is covered with a layer of mold and dirt, it should be washed in the bathroom with detergents and a brush.

When disassembling the indoor unit of the air conditioner, you will need to remove the air filters. They are made of plastic and are designed for rough air purification. Sometimes they are fixed on the lid or inside the air conditioner. The filters are washed under an intense stream of water. A brush will help with this.

The airflow guides should also be removed. Blinds are removed from the grooves. To facilitate the process, you need to slightly bend them. These elements direct the flow of cold air into the room and also need enhanced flushing.

Removing the bottom cover

The next step is to remove the bottom cover. You will need to remove the drain tube and power cord. In the process of this, three latches should be pressed and the drain tray together with the outlet hose should be disconnected from the unit.

Removing terminal blocks

The indoor unit of the air conditioner has terminal blocks. They are disconnected during disassembly, and then the electronic control unit and transformer are removed. In order to remove the first one, it is necessary to wring out the side fasteners, and then pull the device towards you. Before this, the ground wires are unscrewed.

Removing the fan motor

The fan motor can now be removed. To do this, the bolts are unscrewed, which are strengthened to the chassis. The evaporator is raised and the engine is pulled out along with the rotary fan. The motor must be separated from the fan, but first you have to warm up the bolt head with a soldering iron. This will unlock the thermal lock on the motor pulley. Once the fan blades can be removed, they must be washed. Assembly is carried out in the reverse order.

Cleaning the outdoor unit

Outdoor and indoor units of air conditioners are equally in need of maintenance. The frequency for the first is twice a year, which is true even with intensive use. A vacuum cleaner is required for this, but the device must be powerful enough to extract dust from external filters and heat exchangers.

On your own or with the help of specialists

If the unit is located at an impressive height, then you can unscrew the protective grille and vacuum it, as well as wipe the insides from dust. Otherwise, you can seek help from professionals who will remove the air conditioner using climbing equipment or a tower. Cleaning yourself can be done using compact senders, but the air conditioning system will have to be de-energized and turned on only 30 minutes after the end of the service.

Finally

During the operation of the split system, dust settles on the fan impeller, where a “fur coat” of dirt is formed. This prevents the passage of air flow when blowing the evaporator. The latter freezes over, and the user does not receive normal cold and intense air flow.

Cleaning the fan of the indoor unit of the air conditioner is also required when you see black flakes flying out of the appliance. This suggests that the amount of dirt is so large that it does not hold onto the internal nodes. As a preventive measure, from time to time you can dismantle the fan and wash it with chemicals. But not all models make it easy to extract this part of the system.

How to disassemble the air conditioner with your own hands to eliminate the unpleasant smell from the split system? To disassemble a wall-mounted air conditioner with your own hands, you must first familiarize yourself with some of the features of household air conditioners.

How to disassemble the air conditioner

One day, any user of a wall-mounted household air conditioner faces the following unpleasant problem: when the split system is turned on, a stream of cool air bursts out of its outlet, filled with a slightly sweet smell of already stagnant mold. This means that it is time for you to carry out maintenance of your air conditioner, that is, wash it thoroughly, and inside the system. There are two ways to solve this problem: the first is to call the wizard (however, this method is expensive), the second is to independently disassemble the split system and then clean it on your own.

We suggest that you do everything yourself, because in this way you will be able to save a certain amount of money, moreover, this skill may come in handy in the future. We present you a detailed guide for disassembling the indoor unit of the air conditioner, which will help you solve the problem of unpleasant odor from the split system. The considered algorithm for disassembling the air conditioner is typical, so it is suitable for many brands of modern air conditioning devices. So, to disassemble the air conditioner yourself, you will need several minus and plus screwdrivers of various diameters, as well as a set of hex stars (not for all models of split systems). If you already have such a simple arsenal, then you can start disassembling the indoor unit. Please note that in the process of cleaning the air conditioner, you do not have to remove the device from the wall, disconnect the copper line and drain the freon.

First of all, turn off the power to the air conditioner, then remove the protective filters from the indoor unit of the device. This process is described in detail in the standard service manual for your split system. Next, remove its front panel from the block, to do this, unscrew the two bolts that are closed with protective plugs, and then pull the frame towards you (it is held on top by two latches). The lid on the inside will be covered with mold and dust, so immediately send it to the sink. Next, remove the blade that directs the air flow, to do this, apply a little physical force and pull it out of the slots. Then remove the lower part of the air conditioner indoor unit from the latches, and then disconnect the split system drain hose and its supply wire.

Next, you need to disconnect all the wiring, while it is better to write down how the wires are located. If you are too lazy to write down, and besides, you can boast of your grandiose knowledge of radio engineering, then when you assemble the air conditioner back, you can use its electrical circuit, which is located on the inside of the front cover of the indoor unit.

Then wring out the mounting brackets, then remove the housing of the electronic unit and the transformer. Then you need to press the three support latches and carefully dismantle the drain and outlet hose. The hole for blowing air from the indoor unit, as well as the blades of the built-in fan, will be covered with a strong coating, which exudes an unpleasant odor. After that, unscrew the air conditioning motor support bolts, carefully lift the radiator, and remove the motor support. Then remove the blades, as well as the engine from the cell, and you can carefully lay the radiator back so that it does not suddenly fall.

Then remove the heat lock that is on the electric motor pulley mounting bolt. Be aware that this is not easy to do. To prevent the rubber element that transmits energy from accidentally burning out, you need to gently heat the bolt head with a thin soldering iron, while periodically trying to unscrew it. When you manage to separate the blade from the motor, send all contaminated elements of the system to the sink. To wash all the parts, you will need a bottle of detergent, a brush with fairly long bristles, and plenty of water. The assembly of the air conditioner is carried out in the reverse order.

You can see for yourself that the design of the indoor unit of a wall-mounted split system is not very complicated. Therefore, in order not to spend extra money, you can clean the device yourself, besides, you now know how to disassemble the air conditioner with your own hands.

For the dismantling of the most popular type of air conditioners - split systems - experts charge a fee at the rate of 1 p. for every kilowatt of power. Many owners of cooling devices who have to move, in order to save their hard-earned money, undertake to dismantle the air conditioner with their own hands. To do the job cleanly, avoiding fatal errors, a number of useful recommendations will help.

Possible problems with self-removal

The story of how to dismantle the air conditioner with your own hands should begin with a warning about the pitfalls awaiting an unprepared master. Here's what can happen:

  1. Refrigerant leak: freon escaping into the atmosphere will not cause an environmental disaster, there is no need to be afraid of this. But such an event will not be in vain: when installing an air conditioner in a new place, you will have to pay for its refueling. Therefore, it is highly desirable to dismantle the device so that all the available refrigerant remains inside it.
  2. Ingress of water or dust into the internal circuit: such an “additive” to the refrigerant quickly renders the compressor unusable. Perhaps, at first glance, water may seem like a completely harmless substance, but you need to consider that in the evaporator it will freeze, turning into ice. And these are already solid particles, the presence of which is “incompatible with the life” of the compressor. To minimize the risk of moisture entering the internal circuit, avoid dismantling the air conditioner during rain or snow.
  3. Falling outdoor unit: Even if the outdoor unit is hanging next to a balcony or window, it is extremely inconvenient to operate. At the same time, this knot is quite heavy, so that, without calculating your strength, you can easily drop it. Professionals are insured against such accidents, since when working above the first floor they use an aerial platform or equipment for industrial mountaineering. For the sake of reliability, the inhabitant should invite an assistant.
  4. Damage to the elements of the device: the most noticeable are the damage that causes depressurization of the circuit. A crack can be completely invisible, but it is quite enough for freon to leak or dirt and water to get inside. To avoid such troubles, first of all, you should be careful.

When performing such a complex operation with your own hands as disconnecting the evaporator of the indoor unit, it is highly advisable to use not improvised tools - a screwdriver and pliers, but professional ones designed specifically for it.


A set of necessary tools and materials for dismantling

Users at this stage often wield what they have to, as a result of which the evaporator tubes located close to the mounts are damaged. The problem is that a professional tool is quite expensive and even renting it can cost an amount that is quite commensurate with the cost of the services of a qualified master.

Preparing the air conditioner: “packing” freon

So, first of all, it is necessary to ensure the safety of the refrigerant. To understand how this is done, you need to remember the device of a split system. It is a closed circuit filled with freon, which consists of a compressor, two relatively speaking chambers (evaporator and condenser) and freon pipelines connecting these elements (copper tubes).


Schematic diagram of a split system

From the condenser to the evaporator, the refrigerant enters in liquid form, so the tube through which it flows has a smaller diameter.

On the second freon pipeline - from the evaporator to the compressor - freon follows already in a gaseous state, therefore the diameter of this branch is increased.

To carry out dismantling without loss of gas, it is necessary to collect it in the condenser:

  • during the operation of the air conditioner for cooling, the valve between the condenser and the thin tube is closed;
  • when all the refrigerant, due to the operation of the compressor, “moves” into the condenser, it will also be necessary to close the valve between the thick tube and the compressor.

We shut off the refrigerant

An important point: after what time should the second valve be closed? It is best to monitor the gas pressure on a vacuum gauge. But for this you will have to borrow a special tool from the masters - a manometric manifold.

Those who do not have such an opportunity simply wait about a minute: as experience shows, during this time, a household air conditioner usually manages to pump almost all the freon into the condenser.


Manometers for pressure control when pumping freon

Let's move from theory to practice:

  1. If you managed to get a manometric manifold, attach it to the nipple (schrader valve) on the fitting to which the "gas" freon pipeline is connected. In the absence of such a tool, this item is simply skipped.
  2. We turn on the air conditioner and enter from the settings panel: cooling operation, turbo mode, temperature - as low as possible (the permissible minimum must be specified in the passport). So the device should work for 10 minutes.
  3. On the outdoor unit, find the valve, to the fitting of which the liquid freon pipeline is connected (recall that it is thin). Under the protective cap, which must be removed, slots for the hexagon will be found. After inserting the key, the valve must be closed.
  4. Now you should watch the pressure gauge or, if it is not there, the clock. In the first case, we expect the device to show the presence of a vacuum; in the second - we detect 1 minute.
  5. Next, you need to remove the protective cap from the second valve on the outdoor unit, to which a thick "gas" line is connected, and also close it with a hexagon. After that, the air conditioner is immediately turned off. We return the protective caps to their places.

Everything, now the freon is trapped and the system can be safely disassembled and dismantled.

Instructions for dismantling the air conditioner with your own hands

We proceed directly to the uninstallation.

outdoor unit

Disconnect freon lines. This can be done by unscrewing the nuts with which the lines are screwed to the fittings of the outdoor unit. This method is resorted to if the length of the tubes allows them to be used in a new place. Open fittings must be securely sealed with electrical tape or tape - this will prevent them from clogging.


Removing the outdoor unit

But in most cases, freon pipelines are not reused, especially since their extension is not allowed. Then the tubes are simply cut with a pipe cutter at a distance of 150–200 mm from the fittings, immediately caulking their ends with a bench vise.


Minted Highways

Advice. If it is known that the air conditioner will be stored unassembled long enough, the tubes can be filled with nitrogen and tightly sealed. Unlike air, more precisely, the oxygen contained in it, nitrogen does not lead to the oxidation of the material.

After all the manipulations, it is necessary to remove the thermal insulation from the outer part of the freon pipelines.

After making sure that the device is disconnected from the mains, remove the protective cover over the place where the electrical cable is connected. Its terminals must be marked in some way to avoid confusion when connecting to a new location. After that, you need to unscrew the clamps with which the wires are screwed to the contacts of the outdoor unit. The freed end of the cable is screwed to the freon ducts, which are then manually straightened in order to be able to pull them out through the hole in the wall.

Now we unscrew the nuts holding the outdoor unit on the brackets, and together with the assistant remove it, and then the brackets themselves.

Note! During storage and transportation, the outdoor unit must be in a vertical position. During transportation, it is very important to avoid shaking and bumps - for this it is better to place the unit in a box with foam pre-laid in it.

Disconnecting the compressor

If the air conditioner is dismantled in order to repair the compressor, the latter must be properly disconnected. It is done like this:

  1. The covers are removed from the outdoor unit.
  2. After that, it will be possible to disconnect the suction and discharge pipes from the compressor.
  3. Disconnect the wires supplying the compressor and fan.
  4. We unscrew the fasteners holding the valves and the capacitor.
  5. We remove the condenser, gaining access to the compressor mounts.
  6. We remove the compressor.

By doing so, you will eliminate the risk of damage to the piping piping. Another plus: it becomes possible to repair several elements of the outdoor unit at the same time, which will allow you to cope with the task faster.

To work with the compressor, you need to pour out the oil in it.

In the case of a piston model, it drains without problems through the suction pipe. For spiral and rotary models, you have to drill the bottom (hole diameter - 5-6 mm). It is impossible to drill through, otherwise chips will get inside. A thin partition is left, which is then pierced with a punch.

How to remove the indoor unit

To access the locks of the indoor unit, you need to remove the front panel from it. Then the freon lines and electric wires are disconnected, the latches are snapped off and the block is removed from the guides.


Removing the indoor unit

Note! At this stage, the average person faces some difficulties: with careless actions, the evaporator latches can easily be damaged.

The manufacturer usually closes this element with a lid, the latches of which are pressed against the wall. They were made hard to reach on purpose: such a precautionary measure, according to the developers, is a guarantee that only specialists will be involved in dismantling the device. To get close to the latches, use two thin screwdrivers. In this case, it is necessary that someone hold the block.

Care should also be taken when snapping off the latches holding the block on the rails. If they are damaged, the device cannot be firmly fixed in a new place and it will quickly fail due to vibrations.


Be careful with latches!

Having removed the indoor unit, unscrew the mounting plate, remove the freon ducts with the supply cable from the wall and unscrew the decorative box laid along the outer wall.

Features of work in winter

At low temperatures, it is not possible to pump freon into the condenser: the oil in the compressor becomes thick and an attempt to turn on the air conditioner under such conditions will lead to a breakdown of the supercharger. Such a danger does not threaten only models equipped with the so-called winter kit, which has a heater for the compressor crankcase and drainage, as well as a fan speed retarder.

Manometric station for collecting refrigerant

Those who do not have such a system can remove the refrigerant using a manometric station to collect freon. It is connected, like the gauge manifold, to the shredder valve.

Video: we dismantle the air conditioner with subsequent installation in a new place

The procedure for dismantling the air conditioner is technically quite simple. The difficulty, from the point of view of an ordinary user, is that some operations are difficult to perform without a professional tool. If you nevertheless firmly decided not to turn to specialists, we recommend inviting another person to help - then even without special tools the task will be quite feasible.

Regular maintenance of the air conditioner requires disassembly of its indoor and outdoor unit. This is necessary when replacing parts of the split system and its complete cleaning. It is worth understanding the features of the process and the consequences of improper disassembly.

How to remove the indoor unit

To remove the indoor unit of any type of air conditioner, you need to snap off the bottom clips. For most devices, they are located below and are indicated by arrows or serifs. Clip types:

  • The hook for the wall plate is made from above. In these cases, the clips are pressed upwards.
  • Bottom plate hook. In such devices, there are additional holes at the bottom. Fasteners are pulled down from the block.
  • Clips located under the decorative cover. First, remove the cover, and then squeeze the fasteners.

The removed indoor air conditioner module is easier to disassemble.

Dismantling the indoor unit of the air conditioner

You can disassemble the indoor unit of the split system after disconnecting the device from the network. Then open the housing cover and take out the filters. The next step is to remove the case:

  • Any air conditioner has self-tapping screws at the bottom, which are easy to find under the plugs. They need to be unscrewed.
  • Under the cover behind which the filters are located, there may also be self-tapping screws or latches. After unscrewing them, you can slightly open the lower housing element.
  • The next task is to release the latches located at the top of the case. They are quite rigid, to detach them you need to find out the features of the fastening. Most often, they can be unlocked by pulling the bottom of the case towards you and up.
  • It remains to disconnect all the wires, if any.
  • Having slightly opened the blinds, it is easy to remove the case by pulling it towards you.

    The next step is to remove the drainage container. Some models are made monolithic, so they will not be able to separate the tray from the body. It is important to understand the features of its installation in order to correctly install it in place during assembly.

    It is recommended to prepare containers for condensate from the tray. To disassemble the container, it is enough to unscrew one screw, and then disconnect the clips at the bottom. From the tray it is necessary to disconnect the blinds motor. After removing the container, the “tail” of the drainage hose is separated.

    Air conditioner indoor unit fan (impeller)

    The next task is to remove the fan (shaft). This procedure is the most responsible and complex. A simple shaft removal option is applicable when it is removed to the left without affecting the control unit and engine:

    • Unscrew and release the left side of the radiator from the device case.
    • Unscrew the fastening on the right in the shaft itself by a few turns. This screw is often heavily tightened, so it is important to be careful not to damage the head of the fastener and break the blades.
    • Remove the shaft from the bottom of the housing, taking care of the safety of the parts. Since the fan is often installed quite tightly, it takes a lot of experience to remove it. The screw can be held with a screwdriver while pushing the shaft.

    When mounting the shaft into the device housing, the screw must be exactly in its original position. Otherwise, the fan will touch the walls.

    There is also a more complicated option for removing the fan. If the shaft is pulled out on the right side, you will have to remove the electric motor and control unit.

    Sequencing:

    • Remove the control unit from the housing. This will require disconnecting all wires and sensors. Then the latches are disconnected and the screws securing the control unit are unscrewed.
    • Loosen all motor fasteners. Detach the shroud from the shaft.
    • Carefully study how the shaft is disconnected from the motor. Carefully bend the copper tubes that go to the radiator.

    Disassembly of the external module

    Dismantling a mobile or window air conditioner does not take much time - just remove the device from the window or remove the air duct. When disassembling a full-fledged split system, it is required to save all the refrigerant.

    The connecting tubes through which freon is transported have different diameters. The thin channel serves to transport liquid refrigerant. A large tube is designed for pumping gaseous freon. When disassembling the air conditioner, it is necessary to “drive” the refrigerant into the outdoor module. Then you can turn off the main channels. To pump the refrigerant, it is necessary, when the device is running, to screw the pipe with liquid freon, which leaves the outdoor unit into the room. The device pumps the gaseous substance into the outdoor unit in 1 minute. After that, turn off the device immediately.

    The disassembly of the outdoor unit of the air conditioner is carried out by two people. In this way, unnecessary risks can be eliminated and the time of work can be reduced.

    After disconnecting the device from the mains, disconnect the cables by marking the terminals.

    The copper channels through which the refrigerant is transported can be straightened by yourself with care. Together with them, the electric cable is removed into the room. It is screwed to the end of the tube. Then you need to unscrew the nuts that hold the outdoor module. Remove the block together. Lastly, the brackets are removed from the wall.

    The removed outdoor unit requires vertical storage and transportation. To avoid possible damage, it is placed in a box with foam.

    Removing the compressor

    In some cases, only the dismantling of the outdoor unit is required, for example, when it is necessary to adjust the operation of the compressor. In this case, the indoor unit remains in place. The main task is to correctly remove the compressor:

  1. dismantle the cover of the outdoor unit;
  2. disconnect the discharge and suction pipes;
  3. disconnect electrical wires;
  4. unscrew the fasteners of the fan and condenser;
  5. remove the capacitor from the case;
  6. dismantle the compressor mounts and the part itself.

By following this sequence of actions, you can reduce the risk of damage to the pipelines and gain access to other elements located in the housing.

Consequences of incorrect dismantling

If dismantled incorrectly, it is easy to damage the air conditioner. Possible adverse effects.
