3. Connect drain hose and refrigerant piping (refer to
Refrigerant Piping Connection
section for instructions).
4. Keep pipe connection point exposed to perform the leak test (refer to
Electrical Checks and Leak Checks
section).
5. After the leak test, wrap the connection point with insulation tape.
6. Remove the bracket or wedge that is propping the unit up.
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.
Step 8: 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 firmly with Teflon 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.
NOTE
To prevent unwanted leaks double check that the unused drain hole is plugged into the rubber plug.
