How to paint the split system indoor unit

Painting the air conditioner the same color as the wall

to get rid of it once and for all ? Degrease and a good paint, like Hammerite, from a spray can ? And how to take out the condensate to create the minimum inconvenience to those who live downstairs ? To the drain, alas, bloodless opportunity not possible (need to drag 8 meters through the loggia and the kitchen). Paint the pipe the color of the facade and take it away from the house ? Maybe there’s a nozzle to make the droplets spray better ?

It’s metal. zinc primer, and polyester powder, it will last a very long time. But nothing lasts forever.

Pardon me, but why paint? The color of the facade? Unfortunately, all three of these cans won’t hold up in the winter. Only a normal paint job in the chamber will save. About drainage. If you can get the water out so that it hits the condenser condenser. It’s a good way to get rid of condensation altogether. Because flowing down the hot heat exchanger, it evaporates. To make a pipe from a sump of an outdoor unit away from a house. The tube is rigid. But it is difficult

mistakes during installation and connection of air conditioner in the apartment.

How to install and connect air conditioner by yourself? Let’s be honest with ourselves and answer this question straightforwardly, even if we are talking about a low-power household variant. no way.

If you do not have special equipment (jacking, torque wrenches, vacuum pump and much more), skills to work with them, then to do it for the first time with his own hands you unlikely to succeed.

No matter how many useful tips and instructions from A to Z you read, you can still miss some unnoticed detail, or do the job due to lack of experience is not enough quality.

As a result after a certain period of time you will have to call specialists and to redo everything.

What is this article for?? That you will be able to control the quality of works by yourself while they are being fulfilled, and you will be sure that your conditioner will work for a long time without any problems.

Where the work begins? First of all you choose a place for installation of air conditioner and mark out a hole for laying of interblock communications.

Then proceed to drill a through hole to the street. You use the drill with length not less than 800 mm and diameter from 45 mm.

For powerful air conditioners with a diameter of over 2.5 watt you will need a drill bit with a diameter of 80 mm.

To avoid dust in the room, in the economic version, you hang a plastic bag under the place of drilling.

Professional installers have long used a construction vacuum cleaner for this purpose.

But if you are drilling through solid concrete walls in a wet way, no protection or vacuum cleaner will save you.

This hole after all communications are put through it is subsequently filled with foam.

Note that for normal drainage of condensate, it is necessary to drill at a slight angle towards the street.

In this case the condensate will flow out without obstruction, and the water will not accumulate and get moldy in the drain.

It is not right. The thing is that when you drill in a predetermined place, you can accidentally hit the armature.

As a result the hole will have to be moved. Because of this the air conditioner itself will be displaced inside the room on some centimeters.

When selecting a location for the through hole and placing the outdoor unit on the side of the window, you must drill so that the hole will end up almost on top level of the outdoor unit.

This will create maximal slope for main pipes and help to avoid oil ingress to evaporator.

A mounting plate expose strictly on a level.

In this case the distance from the ceiling to the air conditioner itself should be not less than 10 cm. It provides good air intake and free assembling-disassembling of the indoor unit.

For a reliable fixation, use quality dowel nails 640mm or 832mm.

Then you can proceed to installing the outdoor unit. Mark mounting points of the brackets.

You drill the holes with the 12 mm auger. After that you fix the brackets with dowel nails 1280mm.

Fasten it firmly, especially if the condo hangs from the side of the house where there is a driveway or sidewalks.

The distance from the rear wall of the outdoor unit to the wall of the building should be at least 10-20cm. Although a lot will depend on the fan’s performance.

Where to place the external unit, under a window or on the side. a matter of aesthetics and usability.

Many people simply do not like the extra meters of hanging cable and pipes hanging on the wall. In this case we choose the side arrangement.

Though, competent installers can lay a cable and a freonconductor very well. Here much depends on the level of professionalism of executors.

Getting ready the tool: what you can refuse from

The meaning of independent dismantling is to save money and time. But it is necessary to dismantle a split system with exact observance of rules. Otherwise expensive freon will leak and you will have to call in a technician to pump out the new portion.

For work you will need a tool; some of its varieties can be replaced by cheaper analogues, and some positions can be (with some reservations) rejected. Ideally, you should prepare the following tools:

  • Low pressure gauge (gauge manifold). With its help one defines pressure after pumping refrigerant into the outdoor unit so it makes no sense to buy it for a one-time operation. If you carry out pumping without errors, you can do without a manometer.
  • A set of hex wrenches. They are necessary, because with their help you unscrew the nipples on the block. For most domestic air conditioners 4 and 5 mm hexahedrons are used. Larger faucets are usually on semi-industrial models.
  • Screwdrivers: flat and shaped (Phillips), adjustable wrench.
  • Pipe cutters and plugs. If there is no trumpet cutter, the usual metal hacksaw will do (though it will not be so convenient).

Dismantling budget depends on whether it can be done from a window or balcony; on higher floors, you will need equipment for industrial climbing. Safety gear is a separate expense item, and you should not skimp on it. It’s also important to understand that you can’t do the job alone. In order to properly dismantle the conditioner you need a helper.

How to correctly connect air conditioner power supply to the mains. General requirements

Properly power the air conditioner from the mains through a circuit breaker from 10 amps. The cross section of the cable from 1.5 mm, three conductors. phase, neutral, ground. While keeping fire safety it is not important which of the three ways you will connect power:

  • Cable installation with a direct connection:
  • Pros: The body of the indoor unit hides the cable out of the wall. The cable is not visible, there is no socket. There is no need to pull the plug out of the socket; it is disconnected through the automatic switch in the switchboard. Reliable power. a separate cable and circuit breaker will definitely handle the load;
  • Cons: you need a separate circuit breaker and cable for the air conditioner. if this is not done, in winter time the equipment will be live. Costs of buying a fuse box and dozens of meters of cable. The cost of additional work on the laying of the cable:
  • Putting a separate socket under the air conditioner:
  • Pros: the system is easily de-energized for the winter or summer vacation season, the air conditioner outlet does not require a separate switch in the switchboard. you can run a cable from a nearby box;
  • Disadvantages: Improperly located socket spoils the appearance:
  • Power supply of air-conditioner from the carrier:
  • Pros: the solution is extremely cheap, when you move the air conditioner to another place, it is easy to move the transfer and the transfer;
  • Disadvantages: often, when using a cheap carrier. the wire of the carrier and its contacts are heated, spoiling the interior of the room.

The best solution of AC power connection is a separate wire powered from a separate automatic unit with nominal value from 10A. In this case a socket is not required

Power cable for indoor and outdoor unit

The power cable is best laid in a box during the renovation. Alternative laying options:

  • Hidden in the plasterboard box. at the stage of its assembly. It is desirable to lead cable in plastic corrugation;
  • To lay a wire under the false or plasterboard ceiling
  • For private houses the variant of laying of air conditioner’s power cable along the facade of a building in metal corrugation or in a pipe;
  • In the plastic cableway along the wall from the distribution box to the indoor unit of the split system.

For more details on how to lead out a wire under air conditioner see the article Installation of air conditioner during repair.

Double-insulated monolithic cable should be used for laying in the wall. Cable cross section 1.5 mm for air conditioners with power up to 25 kV.м., and from 2.5mm for units above 25kv.м. Plastic or metal conduit is required when routing through walls.

The air conditioner can be powered in three ways (depending on the brand and model):

  • External power supply to indoor unit only. The outer one is already powered from the inner one. In this case a usual socket near the inside block is enough;
  • External power supply to outdoor unit. Internal one is powered from external one. In this case, no outlets are needed at all;
  • External power supply for both units separately. Rare case. It is used in the powerful and expensive systems.

Choice of receptacle location

The place where it is better to place the socket, depends on the height of an internal unit. You need to choose model and capacity of split system. How to choose the power read in the article “How to choose an air conditioner”.

Knowing the exact size of the indoor unit, you can position the socket so that it looks harmonious with the body of the unit. The best way to “hide” the socket between the body of the unit and the nearest wall.

How to properly clean an air conditioner by yourself??

In order to properly clean a conditioner at home one usually invites a specialist in this affair.

Can you do the washing by yourself with minimal tools and chemistry??

The master comes, opens a lid, knocks out the filter on a knee, spikes the steam generator for a couple of minutes without disassembling the squirrel wheel.

Wetting the outside with a kerher, splashing all over the walls of the dirty water (the neighbors below will thank you).

They take their money and leave with the feeling that their duty is fulfilled.

And in a couple of months the conditioner starts to smell and grow mold again.

Quality cleaning of the indoor unit with all the disassembly and assembly processes takes at least 2-3 hours. This procedure is not quick and it is necessary to treat it with care.

It should not be confused with the elementary operations of washing the air filters, which takes 10-15 minutes at most.

In general, from words to deeds. We will show you step by step the disassembly of all knots and the nuances, with which you will face, and already on the basis of this you can make conclusions. will you be able to conduct cleaning by your hands or it is better to invite a professional.

Still, after you try to disassemble and assemble the conditioner by yourself the number of appeals to the specialized service-center sharply increases)))

Sometimes even detailed video instructions on YouTube are not very helpful.

At least with the knowledge learned from the article you can easily control the work of a master.

Note that we will talk only about the internal unit, not about the external one!

To get to him safely, except for the specials.of the tool sometimes you also need a special.technique.

The first thing you do is to pull the plug out of the socket and unplug the device from the mains.

After turning it off, let it rest for 30 minutes. This time is not included in the total duration of repair mentioned earlier

This half an hour is needed to cool the heated elements of the system. One more useful advise for those, who will clean the device not for oneself, but for a customer.

Just in case it is faulty. Then you’ll never be able to prove it wasn’t your fault.

So, you unclip the top cover and take out the air filters.

According to the instructions it is recommended to clean them every two weeks. The easiest way is to soap them up with something like bubble wax and sponge them off under warm water.

You can’t wash a really dirty strainer just with tap water.

Otherwise you will have the quest “how to disassemble conditioner and how to live without it”

LG, Samsung and all kinds of Chinese no name models disassemble relatively well. But with the Japanese, you have to disassemble every single screw.

That is why you should place a family member near you so that he could record the whole process on his camera smartphone. It will help a lot in the subsequent assembly of the construction in the reverse order.

Behind the air filter, some models may have a deodorizer.

It’s a thing that is sprayed with different scents and the whole room is filled with the appropriate smells. Remove it as well.

Going down. You open the bottom flap and snap it off on the sides.

Don’t be afraid, it bends very well. Bravely pull it down the middle and pull it out of the grooves at the edges.

If it doesn’t come out straight away, try twisting it. There may be a “latch” (on Toshiba models) that only comes out of the groove in one position.

The baffle plate can also be connected to the air flow guide vanes. Unlatch it from them as well.

You can’t get a rag in the unit to clean the inside walls of the air conditioner without removing the damper itself.

Those who want to save time most often break the louver guides in this way.

Required tools and possible replacements

If you have money, you can hire a master for removal and installation of modern split-systems, not even paying attention to the manufacturers of this tool, from which the price policy changes. But then there is no point in self-disassembly, which is carried out in order to save money. Therefore it is better to replace some kinds of tools with cheaper one, and you will have to refuse from some of them at all.

List of tools that are needed for disassembly:

Manometric manifold. It is a necessary thing, because it will show the pressure when pumping freon into the outdoor unit. And it is this gauge falls into the category of tools, which you should refuse (at your own risk), because its minimum reliable costs 3000-3500.

  • Allen set. This position is indispensable, since you won’t be able to unscrew the pipe unions any other way. Fortunately,
  • Pipe Cutter. It is not expensive (about 300), but you can reduce the expenses even more and buy an ordinary metal saw, which then will be repeatedly useful for household.
  • Flat and shaped screwdriver. Now available at any hardware store or home improvement store.
  • Safety equipment, if the air conditioner is located on the upper floors. Here you should not save money and do not pay attention to the goods,

And another prerequisite. the presence of an assistant, and preferably two. Both outdoor and indoor unit has a solid weight, so you yourself will be problematic, you can accidentally damage the device.

Choosing the place

Installing an air conditioner with your own hands begins with determining the location of the equipment. Since split systems consist of two or more units, you will have to choose a location for both. It is necessary to take into consideration how the cold air will spread in the house or apartment.

We begin from technical requirements. When choosing the location of the indoor unit take into account the following requirements:

  • From the unit to the ceiling. at least 15 cm (some manufacturers have at least 20-30 cm);
  • to a wall on the side. not less than 30 centimeters;
  • Up to an obstacle that will be crushed by a stream of cold air, at least 150 cm.

Outside unit is usually put near a window or on an open balcony, if there is one. On a glazed balcony/alcony, installation on a railing (if this has sufficient load-bearing capacity) or nearby on a wall is possible. If you live on the first or second floor of a high-rise, the outdoor unit tend to put above the window level. away from passersby. On higher floors it is possible to place it under a window or on the side.

If the installation of conditioner with your own hands is planned in a private house, you choose the place, basing on the bearing capacity of the walls. In the case of a ventilated facade, you can use a special fixing or hang the unit on the plinth if there is one.

Choosing a place for blocks of split-systems you should also remember that in most cases minimal and maximal distance between blocks is fixed. Specific figures depend on the manufacturer. For example, the minimum distance can be 1.5 m. Choose the place for installation of the air-conditioner with your hands: 2,5 m (various models of Daikin) and even 3 m (Panasonic). For some manufacturers, the minimum length is not regulated, that is, it can be any. In this case you can install the blocks “back to back”. Fitters call this method of installation “sandwich.

One begins air conditioner installation with his own hands from the choice of its location

A little easier situation with the maximum distance between two blocks. It is usually 6 meters. It could be more, but then you need to refill the system with more freon, and this is an additional cost, and not a small one. That is why one tries to invest invest in 6 meters.

Choose the color and shade you want. there are absolutely no limits, we will produce the paint in the color you prefer. The selection process is similar to choosing paint for a car. you need a sample part (piece of wallpaper, trim), or color number. We can provide a catalog of colors, you choose. we paint.

The most common is to paint the air conditioner black. The second is red and gold. You can also choose “chameleon”. Matt paint looks richer when the conditioner is white, in other variants it is better to choose the glossy.

A good question: Where to install air conditioner in the apartment

To teach how to mount conditioner is a thankless job: it is clear that you unlikely will install conditioner by your hands, but you better invite specialists to install it by all the rules.

paint, split, system, indoor, unit

The aim of this article is to help you to find a place for the inside unit beforehand. So that it is determined by you and consciously. And not a master on the principle: “it’s faster and easier to complete the installation.

Where is better to install conditioner in the apartment Three factors determine the place for an internal unit: the proximity of a window, the location of furniture in the room and the current stage of your repairing.

Renovation completed. not many variantsIf you only think about major repairs and plan to design the interior, it is reasonable to choose the central air conditioning system. Then there will be nothing to disfigure the interior: the block is not seen, only the bars at the top of the wall, as on the photo. But the price of such solution, of course, is incomparably higher than the usual split-system.

If the repair works has been finished recently and you are not planning to “spoil” the finish, the only way is to look for a place for the inside of a conditioner in your apartment. Let’s talk about it

A window can be neglected. Usually conditioner is mounted near the window, but not on the inside walls because they do not want to pull a drainage pipe along the room. It is clear: as soon as they will show you an ugly plastic box, which they are going to use to cover the “line” and they will announce the price per one meter (the farther from the window the more expensive) you will most likely agree with the variant “as near to the window as possible”. This is the first mistake of amateur renovation. Do as it will be convenient to use the air conditioner, not as it is more convenient for craftsmen.

Here everything is like with unplanned sockets. do not want to spoil a good repair, there will be exposed wiring and overhead. Are you ready to “make a mess”, it is possible to hide the routes in a wall, as any electrics. And do not be tied to the window.

Conclusion: plan in advance where to install air conditioner and the fact of its installation. It’s important to do it during or even before the repair, not after its completion. When you have to choose either/or. decoration or beauty of air conditioner’s placing. Although even open wiring to the air conditioner can be made by design-concept (example on the photo).

One should not neglect peopleThe air conditioner unit should be installed so that the stream of cold air was not directed to the heads and backs of people, i.e. it is not allowed to direct the stream to the working place, bed or to the backs of people sitting at the table. Otherwise you can expect frequent colds. Pay attention on the photo that conditioner is located above the entrance in a bedroom. Such variant is possible only in the situation when the position of the conditioner was planned before the beginning of the repairing.

Conclusion: the best place where people are not blowing on their heads and backs. And the air conditioner cools most of the room without being conspicuous. Designers often choose a place above the door or orient the air conditioner towards the door.


Where to hang the air conditioner in the bedroom?The solution for a small bedroom can be placement of air conditioner with the air stream running along the foot of the bed.

If there is no room to turn around at all, choose a model with a multi-directional air flow. Such location of the conditioner in a bedroom is good by the fact that when you work or have a rest, the bottom sash can be closed and the air supply can be direct to the left or to the right.

Important: The air conditioner in a bedroom must be located so that the main stream of air goes near a bed not getting on people who are resting there. The variant can be non-standard, as in the example on the photo. the block is integrated into the false ceiling like a central air conditioning system.

Above the doorThe variant of a conditioner above a door in a bedroom is one of the most widespread and recommended by interior designers. I’d rather have it blowing at my feet than in my head when I’m asleep.

Near the door In the situation, as on the photo, when the door of big size is chosen and the partition does not remain for installation of the unit it is possible to install the unit on the next wall. But again so that it blows on legs.

Opposite the doorIn a situation when the configuration and size of the bedroom allow, the air conditioner is placed on the wall opposite the entrance. Keeping in mind that the airflow should be parallel to the bed without disturbing those who lie on it.


In fact it is not such a problem to hang or hide an air conditioner in a nice way. Look at the location of air conditioners on the photos selected by us and decide. on the example of this photo you will find the way where to install conditioner in your own apartment. Where and how to hide a conditioner in the interior The most important is not to prevent the device from working, when you are chasing a stylish environment. Roughly speaking, to hang up the block and to cover it with curtain is not an option.

It is clear that it is very difficult for the owners of small-sized apartments to find a place, where to install a conditioner in a room. the area is small, furniture is rather dense and no matter how one directs the stream, there will be situations, when it blows on one’s head. Here, unfortunately, there will be no miracles. if you cannot find a “hidden place” out of sight, you should try to make a little-visible conditioner itself. There are a lot of variants.

paint, split, system, indoor, unit

Among furnitureThe main difficulty in search of ideal place for a unit on the wall is in the fact that one cannot install conditioner behind the panel or screen: any obstacle in the way of air will worsen the use of the device.


An ideal variant from the standpoint of aesthetics is to hide the block of conditioner among other constructions of the similar form, for example, pictures and shelves, as on this photo.
