A Warning
Be extremely careful not to dent or damage the piping while bending them away from
the unit. Any dents in the piping will affect the unit’s performance.
Step 5: Connect drain hose
By default, the drain hose is attached to the lefthand 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.
