There are a couple of rules that must be adhered to on this. The unit should be wall mounted and positioned at a minimum height of 1.8m from the floor. To allow sufficient and unobstructed airflow, there must also be 100mm of clear space surrounding the unit in all directions. It should also be established before installation that no pipes run across the proposed site.
The next step here is to fasten a metal mounting plate to the wall and drill a hole of around 65mm in diameter close by. The hole is where your engineer will run connecting cables for the external unit, before fixing the internal unit securely to the wall mount.
2. Installation of the Outdoor Condenser Unit
When positioning the outdoor unit, your engineer must make sure permitted development conditions are met and that the unit stands at least 100mm from the exterior wall.
It’s likely they will also recommend setting the unit on securely fixed brackets, lifting it off the ground to prevent potential damage from pooled rain water. Rubber fixing pads are then used to keep the unit firmly in place and dampen any vibrations.
After this, all wiring will be carefully inspected and the indoor and outdoor units connected.
