Indoor Unit Installation
Step 7: Connect Drain Hose & Refrigerant Piping
In this step you will connect the drain hose and
refrigerant piping to the indoor unit. For detailed
instructions about connecting the refrigerant
piping, please refer to the Refrigerant Piping
Connection section of this manual. By default, the
drain hose is attached to the left-hand side of the unit
(when facing the back of the indoor unit). However, it
can also be attached to the right-hand side. To ensure
proper drainage, attach the hose on the same side
that the refrigerant piping will exit the unit.
Attach the drain hose extension (purchased
separately) to the end of the drain hose.
Wrap the point where the drain hose and drain
hose extension connect securely with Teflon tape
to ensure a good seal and prevent leaks.
Then, wrap the portion of the drain hose that will
remain indoors with foam pipe insulation to
prevent condensation/sweating.

arranged as shown in Fig. 5.10a and follow the
guidelines below to ensure proper drainage.

DO NOT create a water trap.
DO NOT put the end of the drain hose in
water or a container that will collect water.

If the unit is hooked to the wall mounting
plate, you can gain access to the rear by propping
the lower rear portion of the unit at an angle
against the mounting plate using the hinged prop
on the back of the unit, as shown in Fig. 5.9 below.

Extend the hinged prop at the back of the unit
against the mounting plate to prop up the air
handler and gain access to the rear.
NOTE: In some regions, if the unit has a conduit
panel installed, it is required for drainage to
occur on the right-hand side of the unit.
