Indoor unit installation
NOTE:
If you find the electrical wiring is of insufficient length for correct installation, please contact an
authorized service shop.
• The electric wiring must be correctly connected. Incorrect connection can cause spare parts to
malfunction.
• Tighten the terminal screw correctly.
• After tightening the screw, lightly pull the wire to confirm that it is firmly in place.
• If the ground wire is incorrectly connected, there is danger of electric shock.
• The cover plate must be attached, and the connection must be tight. Incorrect installation can
let moisture enter in, which increases the danger of fire or electric shock.
• The piping can extend out from the right, right rear,
left, or left rear.
1. When routing the piping and wiring from the left or
right side of the indoor unit, you can cut off the
frame tailings if necessary. (Show in Fig.7)
(1) Cut off tailings 1 when routing the wiring only;
(2) Cut off tailing 1 and tailing 2 when routing both
the wiring and piping.
2. Remove the piping from the body case, wrap the
piping electrical wiring and water pipe with tape
and pull them through the piping hole. (See Fig.8)
3. Hang the mounting slots for the indoor unit on the
upper tabs of the rear panel and check if it is
correctly attached. (See Fig.9)
4. The installation height should be 2.5m or above
the floor.
1. Align the center of the piping flare with the valve.
2. Screw in the flare nut by hand and then tighten the nut
with a spanner and torque wrench to the specified torque.

NOTE: Connect the pipe to the indoor unit, then to the outdoor unit. Be careful not to bend or
damage the connection pipe. Do not overtighten the joint nut. Overtightening the joint
nut can cause leakage.
