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 wir-
ing.
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 the appliance is hooked firmly on mounting by applying slight pressure to the left
and right-hand sides of the appliance. The appliance should not jiggle or shift.
6.
Using even pressure, push down on the bottom half of the appliance. Keep pushing down until
the appliance snaps onto the hooks along the bottom of the mounting plate.
7.
Again, check that the appliance is firmly mounted by applying slight pressure to the left and the
right-hand sides of the appliance.
If 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 appliance, giving you enough room to connect the refrig
erant piping, signal cable, and drain hose.
