Comfort in a room where you plan to install an air conditioning system depends not only on the technical parameters of the device but also on the correctness of its installation.
That is why it is better to perform all actions correctly from the beginning, in order to save money on repairs or the purchase of new climatic equipment.
Let’s consider step by step how to properly install the ceiling system.
Step #1 – installation of equipment units
Depending on the type of ceiling air conditioner, you should decide on the future location of the internal structure. Cassette and ducted units are installed in the free space between the capital and the suspended ceiling.
The inside of the cassette unit is installed in special hangers which are anchored in one or more cells of the false ceiling.
The duct-type technique can have several ducts in each room, which are connected to the indoor unit and brought to the distribution grilles. Installation is performed over a suspended structure, so it is better to perform it before installing the ceiling.
The number and length of the ducts are determined based on the parameters and area of the room. We recommend reading the rules of calculation of air ducts.
After installation, the ducts are insulated and soundproofed to prevent condensation and increased noise during operation.
Floor-ceiling units are fastened to the ceiling with M10 threaded fixing bolts with strict observance of leveling. If necessary, the ceiling structure is reinforced and leveled.
Installation steps:
- Drilling a hole in the wall with an exit to the street with a diameter of 55 mm.
- Routing the cable duct from the hole to the indoor unit.
- Selecting the optimal place and marking the future holes for brackets to securely fix the outdoor unit.
- Drilling the holes, fixing the brackets, and installing the outdoor unit.
- Installation of the internal structure, depending on the type of split system.
- Connection of drainage system to the internal structure.
- Connecting the electrical system.
- Laying the route: the copper pipe is put on the thermal insulation, and the tubes are flared and connected to the two units.
The reliability of the connection pipes to the outdoor unit and the outdoor unit depends on the tightness of the structure, which directly affects the performance of the device.
Step #2 – pressure and vacuum of the system
After laying the inter-unit communications line is checked for continuity and tightness.
When it is determined that the system is tight, the line is filled with refrigerant.
Most unit models use chlorine-free, two-component R 410A Freon, which is safe for the ozone layer.
If the route is long enough, you will need additional topping up the air conditioning system with refrigerant. The peculiarities of self-filling of the system we have reviewed here.
Stage #3 – commissioning works
After assembly of the system, victimization, and freon filling it is necessary to check the operability of the device and make sure that there are no leaks. For this purpose, it is necessary to switch on the device and start it in all operating modes.
When the efficiency of the device is checked, it is necessary to perform the final actions: to close the hole with assembly foam, silicone sealant, and cement mortar, as well as to remove debris, dust, and residues of materials in the room.
