Carrier 42QHG009D8S - Mount Indoor Unit

Step 8: Mount indoor unit
If you installed new connective piping to
the outdoor unit, do the following:
1. If 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 rmly 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 rmly
mounted by applying slight pressure to
the left and the right-hand sides of the
unit.
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
unit, giving you enough room to connect
the refrigerant piping, signal cable, and
drain hose.
Wedge
3. Connect drain hose and refrigerant
piping (refer to Refrigerant Piping
Connection section of this manual for
instructions).
4. Keep pipe connection point exposed to
perform the leak test (refer to Electrical
Checks and Leak Checks section of
this manual).
5. After the leak test, wrap the connection
point with insulation tape.
6. Remove the bracket or wedge that is
propping up the unit.
7. 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.
UNIT IS ADJUSTABLE
Keep in mind that the hooks on the
mounting plate are smaller than the holes
on the back of the unit. If you nd that
you don’t have ample room to connect
embedded pipes to the indoor unit, the unit
can be adjusted left or right by about
30-50mm (1.25-1.95in), depending on the
model.
