Indoor Unit Installation
Step 5: Connect drain hose
By default, the drain hose is attached to the left-hand
side of unit (when you’re facing the back of the unit).
However, it can also be attached to the right-hand side.
NOTE ON DRAIN HOSE PLACEMENT
Make sure to arrange the drain hose according
to Fig. 4.6a.
DO NOT kink the drain hose.
DO NOT create a water trap.
DO NOT put the end of drain hose in water
or a container that will collect water.
ENSURE UNUSED DRAIN HOLE IS PLUGGED
To ensure proper drainage, the drain hose must exit
the unit on the same side as the refrigerant piping.
1.
Wrap the connection point firmly with Teflon tape
to ensure a good seal and to prevent leaks.
2.
For the portion of the drain hose that will remain
indoors, wrap it with foam pipe insulation to
prevent condensation.
3.
Remove the air filter and pour a small amount of
water into the drain pan to make sure that water
flows from the unit smoothly.
4.
To prevent unwanted
leaks be sure that
the factory installed
rubber plug is in the
unused drain hole.
