NOTE ABOUT WIRING
The wiring connection process may differ slightly between units and regions.
Step 7: Wrappiping and cables
Before passing the piping, drain hose, and the signal cable through the wall hole, you must bundle them
together to save space, protect them, and insulate them(Not applicable in North America).
1. Bundle the drain hose, refrigerant pipes, and signal cable as shown below:
Indoor unit
Signal wire Drain hose
DRAIN HOSE MUST BE ON BOTTOM
Make sure that the drain hose is at the bottom of the bundle. Putting the drain hose at the top of the
bundle can cause the drain pan to overflow, which can lead to fire or water damage.
DO NOT INTERTWINE SIGNAL CABLE WITH OTHER WIRES
While bundling these items together, do not intertwine or cross the signal cable with any other wiring.
2. Using adhesive vinyl tape, attach the drain hose to the underside of the refrigerant pipes.
3. Using insulation tape, wrap the signal wire, refrigerant pipes, and drain hose tightly together.
Double-check that all items are bundled.
DO NOT WRAP ENDS OF PIPING
When wrapping the bundle, keep the ends of the piping unwrapped. You need to access them to test for
leaks at the end of the installation process (refer to Electrical Checks and Leak Checks section of
this manual).
Step 8: Mount indoor unit
lf you installed new connective piping to the outdoor unit.do the following:
1. lf you have already passed the refrigerant piping through the hole in the wall, proceed to Step 4.
2. Otherwise, double-check that the ends of the refrigerant pipes are sealed to prevent dirt or foreign
materials from entering the pipes.
3. Slowly pass the wrapped bundle of refrigerant pipes, drain hose, and signal wire through the hole
in the wall.
4. Hook the top of the indoor unit on the upper hook of the mounting plate.
5. Check that unit is hooked firmly on mounting by applying slight pressure to the left and right-hand
sides of the unit. The unit should not jiggle or shift.
6. 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.
7. Again, check that the unit is firmly mounted by applying slight pressure to the left and the
right-hand sides of the unit.
