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 rmly with Te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 lter and pour a small amount
of water into the drain pan to make sure that
water ows from the unit smoothly.
PLUG THE UNUSED DRAIN HOLE
To prevent unwanted leaks you must plug
the unused drain hole with the rubber plug
provided.
