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.
