13-1 PREPARATION STEPS BEFORE INSTALLATION
STEP (1) :Selecting Wall Hole Location
Back right or Back left piping :
In case of passing refrigerant piping lines, electrical cables and condensate drain line behind the unit,
drill a hole of 65mm behind the unit in one of the following locations as per the section :
Right Side or Left Side Piping :
In case of passing refrigerant piping lines, electrical cables and condensate drain line from unit right side
or from unit left side, remove the pipe cover form the side panel.

Step (2): Making Wall Hole Precautions:
Before making a hole, check carefully the following points :
•
The wall is flat and perpendicular.
•
If the wall is not flat and perpendicular, the indoor unit can
be unstable and condensate drain can spill.
•
No studs or pipes are directly run behind the spot to be cut.
•
No electrical wiring or conduits are located.
•
Drill a hole of 80-95 mm to pass the refrigerant lines, drain
hose and electrical cables. The wall hole can be made as
required in either location (1) or (2).
When making wall hole, make sure to drill outwards at a
downward angle, so that the height difference between the
entrance and exit of the hole is at least 5-10 mm.
Step (3): Cutting Sleeve For Wall Hole
•
Measure the thickness of the wall from the inside edge to the
outside edge and cut PVC pipe at a slight angle 6mm shorter
than the thickness of the wall.
Step (4): Mounting Sleeve Into Wall Hole
•
After making hole, a sleeve must be mounted into wall hole
and its width to be equal to wall thickness to pass refrigerant
lines, drain hose and electrical cables through it the wall hole.
