INDOOR UNIT INSTALLATION
WRAP PIPING AND CABLES
Indoor UnitIndoor Unit
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.
1. Bundle the drain hose, refrigerant pipes,
and signal cable properly.

Insulation
tape
Drain hose
Signal wire
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
refrigerant pipes, and drain hose tightly
together. Double-check that all items
are bundled in accordantly.
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.
MOUNT INDOOR UNIT
1. Slowly pass the wrapped bundle of refrigerant pipes, drain hose, and signal wire
through the hole in the wall.
2. Hook the top of the indoor unit on the upper hook of the mounting plate.
3. 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.
4. 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.
5. Again, check that the unit is firmly mounted by applying slight pressure to the left and
the right-hand sides of the unit.
Sometimes, if the refrigerant pips were already embedded in the wall, or if
you want to connecting the pips and wires on the wall, do as below:
i. Hook the top of the indoor unit on the mounting plate without piping and wiring.
ii. Lift the indoor unit opposite the wall, unfold the bracket on the mounting plate, and
use this bracket to prop up the indoor unit, there will be a big space for operation.
iii. Do the refrigerant piping, wiring, connect drainage hose, and wrap them as
instructed.
