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 32mm in 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 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 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 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.
