1. Choose the Location and Install the Indoor Unit

The indoor unit’s location will depend mainly on the length of the refrigerated link supplied with the kit. It is necessary to imagine both the indoor and outdoor units’ positions according to this criterion. The indoor unit should be placed at least 15cm from the ceiling and above 2m in height on a wall facing the outside. Avoid positioning it near a heat source.

The support plate makes it possible to make a “blank” presentation to define the holes required for fixing the module. Use a tape measure and a spirit level, mark the anchor points for the plate. Also, keep the position of the through-hole for the refrigeration duct and the connecting cables. Using a hammer drill to drill holes for the anchors to choose in function of the material making up the wall.

2. Drill the Wall for the Passage of the Pipes

To connect the two parts, a refrigeration connection precharged with refrigerant is made up of two insulated copper tubes closed at their end by clever sealable connectors that prevent the loss of liquid. A condensate drain pipe and electrical supply, and connection cables complete the installation kit.

For the passage of the pipes, drill a pilot hole using a long bit. This right through drilling must be inclined downwards, outside (ideal angle: ± 5 °).

Then use a drill fitted with a tungsten carbide hole saw of sufficient diameter to allow passage of the refrigeration connection, the drainpipe, and the electric cables. Attention, before drilling a wall with the hole saw, remove the percussion function of the drill and use it in drilling mode.

3. Install the Outdoor Unit

Before choosing the outdoor unit’s location, take into account the length of the refrigeration link to be connected. Also, choose a place free of obstacles and in the open air for cooling the compressor. Avoid installing it in a draft, which carries dust that can clog it. Also, consider the noise that the outdoor unit generates and place it in such a way as to avoid noise nuisance to the neighborhood.

After having identified the possible location, defined by the length of the connecting beam, you have the choice between 2 solutions:

  • The outdoor unit is placed high, in this case, a bracket, supplied or purchased separately, is necessary for a solid fixing.
  • The outdoor unit is fixed to the ground, in this case, the support requires anchoring to a concrete surface. It should be isolated from the ground to reduce vibrations.

In all cases, it is necessary to place anti-vibration mounts (silent block) to absorb vibrations and reduce noise.

4. Install the Connections

To set up the connections between the two units during, it is good practice to place PVC ducts on the path of these connections to make an appealing AC installation.

Both units produce condensation, which is evacuated through the drain ducts. You must place these in the lower part in the crossing of the wall. Then direct them to the point of discharge that is most favorable for emptying. Provide a reception area capable of receiving a maximum of 30 liters per day.

The refrigeration connection includes sealable connections that allow each device to be connected without losing refrigerant.

Electrically connect the units and connect the power supply to the mains.

5. Perform the Usual Checks

Once the indoor unit has been installed, remove the front filter and pour a little water into the condensate receiving area. If the flow spreads easily to the drain point, it means that the installation has been carried out correctly.

After allowing the installation to stand for a few hours, start the air conditioning and carry out a leak test using an aerosol leak detector.

You can adjust the temperature to your liking with the help of the remote control. However, for your comfort, it is better to avoid temperatures that are too low because they are a source of health problems.


AC installation at home requires you to master these DIY hacks: knowing how to use a drill, drill a wall, choose dowels according to the materials, use a spirit level, record a measurement with a tape measure, follow assembly instructions, and know-how to make measurements, and safe electrical connections. If you do not have these skills don’t worry and search online for Ac services in Lahore to do the installation for you in a hassle-free, quick, and economical way.
