FINAL TUBING CHECK
IMPORTANT: Ensure certain factory tubing on the indoor unit
has not shifted during shipment. Ensure tubes are not rubbing
against each other or any sheet metal. Pay close attention to feeder
tubes, making sure wire ties on 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. 27). 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 drain hose.
c. Wrap the connection point firmly with Teflon tape to
ensure good seal and to prevent leaks.
d. For the portion of the drain hose that will remain indoors,
e. Wrap it with foam pipe insulation to prevent condensation.
f. 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 you must plug the unused drain hole with
the rubber plug provided.
