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
gradienter 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 connecting
cable. After connecting, wrap the piping, cable and drain hose together with thermal insulating
materials.
NOTE: Do not connect to power supply during installation.

NOTE: Drain hose is prepared by user.
• Drain hose should point downward for easy drain
flow. Do not twist the drain pipe, leave it sticking
out or waving around, do not immerse the end in
water. If an extension drain hose is connected to the
drain pipe, make sure to be thermally insulated
when passing it through the indoor unit.
• When the piping is directed to the right, piping,
power cable and drain hose should be thermally
insulated and fixed at the rear of the unit.
Piping Connection:
a. Connect indoor unit pipes with two wrenches. Pay
special attention to the torque allowed as shown
below to prevent the pipes, connectors and flare
nuts from being deformed and damaged.
b. At first fingers-tighten them, then use the wrenches.
