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.
1. To ensure proper drainage, attach the drain hose on the same side that your
refrigerant piping exits the unit.
2. Attach drain hose extension (purchased separately) to the end of drain
hose.
3. Wrap the connection point fi rmly with Tefl on tape to ensure a good seal and
to prevent leaks.
4. For the portion of the drain hose that will remain indoors, wrap it with foam
pipe insulation to prevent condensation.
5. 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. If not, make adjustments
and test again to see if the condensate will fl ow freely.

 DO NOT kink the drain hose.

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