FINAL TUBING CHECK
IMPORTANT: Ensure the certain factory tubing on the indoor
unit has not shifted during shipment. Ensure the tubes are not
rubbing against each other or any sheet metal. Pay close attention
to feeder tubes and make sure the wire ties on the feeder tubes are
secure and tight.
DRAIN CONNECTIONS
Connect the drain line. The drain line must not have a trap anywhere
in its length, must pitch downwards, and must be insulated up to the
outside wall (see Fig. 18). By default, the drain hose is attached to the
left−hand side of unit (when facing the back of the unit). However, it
can also be attached to the right−hand side.
a. To ensure proper drainage, attach the drain hose on the
same side that your refrigerant piping exits the unit.
b. Attach a drain hose extension (purchased separately) to
the end of the drain hose.
c. Wrap the connection point firmly with Teflon tape to
ensure a good seal and to prevent leaks.
d. For the portion of the drain hose that remains indoors,
wrap it with foam pipe insulation to prevent
condensation.
e. Remove the air filter and pour a small amount of water
into the drain pan to ensure that water flows from the
unit smoothly.
Plug the Unused Drain Hole
To prevent unwanted leaks, plug the unused drain hole with the
rubber plug provided.

NOTE: It is not recommended to add additional insulation to the
refrigerant pipes provided with the product. The factory insulation
is sufficient. Additional insulation may keep the product from
attaching flush to the wall.
NOTE: For applications where gravity cannot be used for
drainage, a condensate pump accessory is available. Consult the
condensate pump Installation Instructions for more information.
