Indoor installation continued
Wrap piping and cables
Before passing the piping, drain hose, and the signal cable through the wall bundle them
together to save space, protect and insulate them.
Bundle the drain hose, refrigerant pipes, and signal cable
as shown. Make sure the drain hose is at the bottom of
the bundle. Putting the drain hose at the top can cause
the drain pan to overflow, which can lead to fire or water
damage.
While bundling, DO NOT intertwine or cross the signal
cable with any other wiring.
Using adhesive vinyl tape, attach the drain hose to the underside of the refrigerant pipes.
Using insulation tape, wrap the signal wire, refrigerant pipes, and drain hose tightly together.
When wrapping the bundle keep the ends of the piping unwrapped so they can be tested for
leaks at the end of the installation process.
Mount indoor unit
1. Check the ends of the refrigerant pipes are sealed to prevent dirt or foreign materials from
entering the pipes.
2. Slowly pass the wrapped bundle of refrigerant pipes, drain hose, and signal wire through
the hole in the wall.
3. Hook the top of the indoor unit on the upper hook of the mounting plate. Check that the
unit is hooked firmly by applying slight pressure to the left and right-hand sides of the unit.
The unit should not move.
4. Using even pressure, push down on the bottom half of the unit. Keep pushing down until
the unit snaps onto hooks along the bottom of the mounting plate. Check that the unit is
firmly mounted.
If the refrigerant piping is already embedded in the wall do the following:
1. Hook the top of the indoor unit on the upper hook of the mounting plate.
2. Use a bracket or wedge to prop up the unit, giving you enough room to connect the
refrigerant piping, signal cable, and drain hose.
3. Connect drain hose and refrigerant piping, refer previous pages.
4. Keep the pipe connection points exposed to perform the leak test. After the leak test wrap
the connection points with insulation tape.
5. Remove the bracket or wedge that is propping up the unit, and using even pressure, push
down on the bottom half of the unit. Keep pushing down until the unit snaps onto the
hooks along the bottom of the mounting plate.

Keep in mind that the hooks on the mounting plate are smaller than the holes on the back of the
unit. If you find you don’t have enough room to connect embedded pipes to the indoor unit, the
unit can be adjusted left or right by 30-50 mm, depending on the model.
