Installation of the Housing
It is necessary to ensure that the side louvres are not obstructed when installing into the wall.
Step 1
Remove the air conditioner from it's packaging and slide the air
conditioner out of it's housing.
Step 2
Prepare the hole in the wall so that the bottom of the housing is
well supported, the top has minimum clearace and the air inlet
louveres have clearance as shown. Holes from the outside through
to the cavity should be sealed. The housing should slope down
towards the rear by about 5mm to allow water formed during
operation to drain.
Step 3
Install the housing into the wall and secure. Ensure the foam seals
are not damaged. Flash, seal or fill gaps around the inside and
outside to provide satisfactory appearance and protection against
the weather, insects and rodents.
Installations of the unit into the Housing
1. Slide the unit into the housing until it is firmly against the rear
of the housing. Care is required to ensure the foam sealing
strips on the housing remain in position.
2. Connect the air conditioner to the power and coil excess
cord length beneath the air conditioner base or control box.
3. Engage the Chassis Lock into the bottom housing rail and
secure to the base with the screw provided.
4. Remove the front panel from it's carton and plastic bag and
fit as per the Operating Instruction.
5. Switch unit on. Check for operation of the unit and check for
vibration in the installation.
6. Fit the drain chute to the housing and run a drain line to a
suitable location if required.
