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 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 ON DRAIN HOSE PLACEMENT
Make sure to arrange the drain hose according to Fig. 4.5.
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.
PLUG THE UNUSED DRAIN HOLE
To prevent unwanted leaks you must seal/plug the unused drain hole
