Learn about how to properly carry out the installation of split systems in a private home or apartment, initially to select the location of its parts.
To do this you must take into account the direction of flow distribution of cold / hot air in the room, given the basic technical requirements specified by the equipment manufacturer instructions.
The most common options for the location of the indoor unit split systems - over the bed / sofa. Outside - usually render out and placed on land near a window or balcony slab
There are certain rules that must be considered when choosing the point units of accommodation:
- the distance between the unit and the ceiling should be at least 15-20 cm, although some manufacturers indicate in the instructions of 20-30 cm;
- from the side of the wall - no less than 30 cm;
- up barrier which would impede the flow of exhaust air or scatter - not less than 150 cm.
For the outer part of a split system, the location is selected based on the ability of bearing walls. It can be mounted near a window, on plates, enclosing the loggia or on the wall next to the balcony.
For those who live on the lower floors, the installation of the unit is carried out over the window - as far as possible from passers-by.
Based on the technical requirements to the wall ventfasada used as a platform for fixing the outer split system unit - a possible breaking capacity must be 2.5 times the mass of the installation unit
For multi-storey house, especially if the apartment is on the top floor, the need to attract high-rise specialists or determine the installation point in the ultimate vicinity of the window, which will provide easy access at installation.
Determining the distance between the blocks
Often the choice of equipment placement is governed by the minimum and maximum distance between its parts. These indicators are mainly specified by the manufacturer and depend on the range and performance split-systems.
Sometimes businesses do not indicate the minimum length of the circuit between the two units, so the installation can be executed arbitrarily.
The minimum distance between the blocks split system company Daikin 1,5-2,5 m, Panasonic -. 3 m However, if the blocks are arranged in a meter from each other, the path length should be at least 5 m (the excess fold in the ring and hiding per unit)
Slightly easier to deal with the maximum possible distance between the two units. Standard rate - 5 m is possible and increase the length of the route, but in this case it is necessary to rely on additional costs due to the need freon refill..
Preparing to work
The decision to do the installation of split systems alone comes, as a rule, after finding pricing specialists. Extremely high amounts of work performance, which occupies 3 hours argued for the existence of expensive tools and wear during operation. This is what constitutes the main share of service fees wizard.
If the prices of the installers of split systems are too large, it is necessary to install their own hands, thoroughly studied this type of work technology
If you look at the recommendations of the manufacturer of equipment, it is often in the instructions states that preparatory work can be done on their own, but Mounting pipes to the mains connection of the evacuation process it is desirable to invite individuals with relevant instruments.
Tools for installation
Run standalone installation of the cooling unit can be, because most of the tools are in a suitcase DIY. An exception may be a vacuum pump, but it fly optionally - be able to make such assembly of the old parts.
Some brigade masters do not even use the equipment for laying tracks up to 6 m.
If you are self-installing the air conditioner could not find a vacuum pump, an alternative option would be a powerful compressor from an old refrigerator or a supercharger aquarium
During installation, an important aspect is compliance with horizontal arrangement of the modular systems. Due to these requirements, each phase of the work should be accompanied by a check of the control building level.
If any tool is not available, it can be rented in the hardware store.
Advance will need to prepare the following equipment:
- Puncher. Used for breaching holes in the facade, which will be routed through the track, generalizing the outer and inner blocks.
- Drill with drill bits. Used for mounting fasteners.
- Cutter for cutting pipes of copper.
- A device for removing burrs after cutting pipes. You can use the reamer, file and sandpaper.
- Valtsevatel copper pipes.
Some believe that the use of the reamer does not make sense, especially if casing knife new and does not leave burrs and nicks, but in vain.
Only after making manipulation Flat skimmers edge flared tube can maximize tight cuddle nut, and accordingly, freon leak is unlikely.
Work device for expansion of copper pipes is performed by deformation of the tube on the selected template, thereby forming a cone. This preserves the original wall thickness and a circular cross section
According to the technical installation rules, the existence of a vacuum pump, - conditioning sealing is performed by this equipment. After filling, the route refrigerant evacuation process is carried out.
The acquisition of necessary materials
Components require quite a lot, but they are easily available in any store a profile. Do not forget that the materials should be as qualitative and chosen exclusively for the device is functionally designed to chill.
It is necessary to acquire the wire for the power supply and connecting blocks. In the passport or in the installation instructions of the device always indicates the required parameters.
Standard - a four-core cross-sectional area of 2 mm power cable2 or 2.5 mm2. The length is chosen based on the route distance, given the small stock.
Still need to prepare thick-walled seamless tube type of soft copper, intended for cooling devices. Pipes are chosen smaller and larger diameters. More specific characteristics are specified in the manual.
Length is the length of the track, plus an extra margin of up to 30 cm. During transportation tubes with their edges should be sealed for shelter from dust settling within the product.
Pipes are selected exclusively for the cooling system, their soft copper alloy lends itself well to flare and ensures proper tightness
For pipe insulation used insulation of foamed rubber. Sell it stretches to 2 m. The implementation of insulation measures required length equal to the length of the track. Synthetic insulation applied to two pipe diameters.
As a drainage tube, experts recommend installing the hose-ribbed, fitted inside a plastic spiral. You can also use an alternative detail - polypropylene tube. Its length is the length of the track at a premium of 80 cm.
A still require two bracket L-shaped type, to fix the unit outside. A suitable size of parts is determined by its dimensions, and safety factor of the load carrier must exceed its weight 5 times. Such an increase in the maximum allowable voltage components required to compensate for wind and snow loads.
Buy these components is better for a company that sells parts for domestic split systems.
Following the acquisition of the bracket for mounting the outdoor unit can not do it more openings as This significantly reduces the margin of safety components
As an attachment parts are used: anchors, dowels and screws. Their number, type and parameters are selected based on the types of brackets and the fixing plate, intended for the indoor unit.
It has a value and the type of wall where to be mounted external part of the system. To camouflage communication laid lines need a plastic box of standard dimensions of 60 * 80 cm.
How to install a split system
Self-install the air conditioning system is a real challenge, but there are many nuances in the work and they concern specific models, so the installation process can take some differences. To study all the requirements, you first need to read the instructions exactly to the purchase of the equipment model.
Step # 1 - assembling the outer and inner blocks
The first to be installed indoor unit. Having defined the place of its location, on the wall is made under section marking the mounting card. After drilling backlashes, the plastic plugs are inserted for dowels map hung and fixed dowels.
The most thorough mount must be performed in the lower part of the plate, since at this site placed the latch holding unit
After installing the cartridge, using a spirit level measured exposure horizontally placing the future of the unit. For any non-compliance need to redo all the work done.
At this stage it is necessary preparatory work for laying tracks. First line calculated its location. Next, the drilling of holes in the wall of the facade, given the required gradient of more than 1/100.
Also sloping drilled hole and a diameter of 5 cm, and the tilt angle can be increased in comparison with the track. Thus, the condensate formed would be better to leave the system.
It is possible to carry out removal of the common communications bundle or individually: one hole for the power cable and the copper tube, the other - for drainage
When selecting circuit blocks mounted "back to back", it is required to make check holes, for enclosing the power cable. To do this, verify the location of the ports on the power unit.
And now it is the turn of the outdoor unit installation. When it comes to high-rise building, you will need special equipment for work at height.
As in the former case, should be maintained substantially horizontal block, however, in step markup also use level.
When placing the outdoor unit must be considered limitation regarding its inclination - the maximum allowable deviation angle is 45 °
The mounts each installation point existing hole should be filled with anchor bolts (standard diameter of 10 * 100 mm), irrespective of their quantity. After that, the outdoor unit is set and fixed too fasteners.
Step # 2 - installation of communication lines
Using electric wires and two copper tubes is carried Compound indoor and outdoor units. In addition, the wall will be laid drainage system, responsible for the removal of condensate. These elements are essential to select, connect, stow and secure.
Should first prepare a copper tube, cutting a desired length using a cutter and reamer from the processed edge dents and burrs after cutting procedure.
It is not recommended to use other tools, such as files. After its application, inside the tube falls metal shavings, which will circulate through the system and eventually lead to failure of the compressor.
To hold the copper tube through the wall, the edges should be insulated plug, to protect from dust
Insulation tubes carried by them dressing foamss hoses. He has a short service life - as a sealant foam can not be selected. Performing thermal insulation measures, all connecting portions of the material tightly glued metallic tape.
Now it was the turn to lay drainage and cable. On each wire you need to wear a special tip. They are placed on an insulating material cleared of crimped conductors and forceps.
Ready cable is connected to the air conditioner according to the scheme set out in the manual of the device.
In both blocks at a location slightly above the ports is removable plate designed for connection of copper pipes. Under it placed electrical connectors for cable
The drainage tube is connected to a special terminal on the indoor unit and discharged through a hole in the wall. The tube must be sufficiently long and end not less than 60 cm from the wall.
According to the rules laying is performed at an angle to the exit to the outside. It requires fixing clips every meter length for slack to prevent the accumulation of condensate.
Step # 3 - Connection system blocks
Conducted through the wall of communication are connected to the respective ports. It is important to remember that the total length of the drain pipe can not be more than 20 m. Laying copper pipes It made a loop process for collecting oil, which contains a small amount of Freon.
Drainage can take two ways to bring it down the drain or into the street. The first method is technically correct, but because of the complexity of the play is not widely used.
When the drain pipe is better to avoid sharp turns are not allowed slack - at these sites will collect condensate
In the lower part of the internal system block is a tube with a tip made of plastic. On her dressing-hose corrugation and tightened in place a clamp connection.
For external part of the device, a similar procedure, but many ignore it. If instead of a hose used polymer tube, selected the appropriate adapter. Since it is connected via the output unit and the handset.
To connect copper pipes, they need to be initially routed through the wall with a tube bender. If such a tool is not available, we suggest you read the article, which details how to bend the pipe without special equipment. Learn more - read Further.
Pipes need to give the necessary slope without kinks and sharp crease. The first thing they connected to the indoor unit. For this purpose, the respective ports are attenuated nuts.
Unscrewing will hear the distinctive sound of a hiss escaping nitrogen. It is pumped to the point of production, to eliminate oxidation details. After its descent, remove the cap and unscrew the nut completely. Next, the procedure is performed by rolling.
In the process of expanding the tube is held down hole to prevent metal chips from entering the system
The edges of the tube in the area of 5 cm aligned. Then carried flaring to ensure connection of input and output units. So to get a closed circulation system. Correctness of the implementation mounting plays an important role in finding the maximum tightness properties, in the process of movement of freon.
tube flared edge is connected to the desired output and fixed nut. It is forbidden to use any attachments - sealants, gaskets, etc. Copper tubes used provide the necessary sealing.
Combining copper tubes, efforts must be made 60 kg, only copper obozhmet integral fitting and contact is leaktight
Doing a similar action with all four ports. After connection setup should last stage conditioning system - eliminating air and moisture as well as possible argon residues that could accumulate in the mounting process.
Step # 4 - vacuuming
During the installation work in the tube enters the air conditioner and if it is not removed, it will be in the air conditioning system. The result is enhanced load on the compressor, respectively, its rapid heating.
Also, the water particles have a negative impact on all items. In the freon contained proportion of lubricating oil, its hygroscopic consistency on contact with water becomes less efficient. As a result of the wear components to accelerate.
Two methods can be used to remove air: vacuum pump or a small amount of freon liquid, which descends from the block located outside. In the manufacture of the outdoor unit, manufacturers run by its freon with a small surplus.
"Puff" method is repeated several times, with the second attempt to perform with top flap. If the path length of 2-3 meters - the procedure is carried out 3 times, at four-meter - 2 times
An alternative to costly vacuum pump can serve the release of excess refrigerant from the outdoor unit system. To do this, unscrew the valve on his cap. Must work with the lower port of larger diameter. Under its hood is a hexagonal socket. Based on his settings, select appropriate key.
A suitable key commit valve rotation of 90 ° and a second return it to its former position. Thus, the system includes a small amount of CFC and increased pressure is created. Second touch of a finger on the spool, located on the same port, releasing the excess refrigerant and gases from the system.
After complete removal of the air outlet valve flap is twisted, and the valves are fully opened and the Freon flows in a split system. To check the tightness of connections, they are coated with soap suds.
In this air-conditioning system installation process is complete, you can proceed to the immediate operation.
