5 - Installation
Unit installation entails :
- preparation of the masonry
- physical unit installation
- connection of the unit to an earthed mains outlet.
5.1 - Unit clearances
A minimum of clearance is necessary around the units to ensu-
re proper air circulation and easy access for maintenance.
Clearance required for units
Preparation of the masonry :
Create an opening in the outer wall to suit the external dimen-
sions of the window unit.
Physical unit installation :
- Remove the filter from the unit.
- Remove the front panel.
- Slide the unit out of its casing.
- Place the unit casing in the opening in the wall. Drill holes in
the casing to suit the thickness of the wall to enable the casing
to be fixed in the opening with screws and wall plugs (see dia-
gram below).
- Install a bracket (B) under the outdoor part of the unit to pro-
vide additional support if necessary.
- Fit the unit into its casing with a 1 or 2° downward slope
towards the outside. This will facilitate evacuation of conden-
sates.
Note : The air inlet grille must be outside.
Note : If the wall is particularly thick, make cut-aways on the
outside of the hole to enable proper air circulation.
