Indoor unit installation
1. Installing the Mounting Plate
Select a location to install the mounting plate according to the indoor
unit location and piping direction.
Adjust the mounting plate horizontally with a horizontal ruler or
plumb line.
Drill holes 32 mm deep on the wall to fix the plate.
Insert the plastic plugs in the hole, then fix the mounting plate with
tapping screws.
Check that the mounting plate is well fixed. Then drill a hole for the
piping.
NOTE:
The shape of your mounting plate may be different from the one
above, but installation method is similar.
2. Drill a Hole for Piping
Decide the position of the hole for piping according to the location of
the mounting plate.
Drill a hole on the wall. The hole should slightly be inclined downward
toward outside.
Install a sleeve through the wall hole to keep the wall tidy and clean.
3. Indoor Unit Piping Installation
Fit the piping (liquid and gas pipe) and cables through the wall hole
from outside or fit them from inside after completing indoor piping
and cables connections so as to connect to outdoor unit.
Decide whether to saw off the plastic part in accordance with the
piping direction (as shown below).
NOTE:
When fixing the pipe along directions 1, 2 or 4, saw the
corresponding plastic part off the indoor unit base.
After connecting the piping as required, install the drain hose. Then
connect the power cords. After connecting, wrap the piping, cords
and drain hose together with thermal insulating materials.
IMPORTANT:
Piping Joints Thermal Insulation:
Wrap the piping joints with thermal insulating materials and then
cover with vinyl tape.
