Step 4: Prepare refrigerant piping
The refrigerant piping is inside an insulating sleeve attached
to the back of the unit. You must prepare the piping before
passing it through the hole in the wall.
1. Based on the position of the wall hole relative to the
mounting plate, choose the side from which the piping will
exit the unit.
2. If the wall hole is behind the unit, keep the knock-out panel
in place. If the wall hole is to the side of the indoor unit,
remove the plastic knock-out panel from that side of the
unit. This will create a slot through which your piping can
exit the unit. Use needle nose pliers if the plastic panel is
too difficult to remove by hand.
3. Connect drain hose step. If there is no embedded
piping, connect the indoor unit’s refrigerant piping to the
connective piping that will join the indoor and outdoor units.
Refer to the Refrigerant piping connection section of this
manual for detailed instructions.
NOTE ON PIPING ANGLE: Refrigerant piping can exit the
indoor unit from four different angles: left-hand side, right-
hand side, left rear, right rear.
CAUTION
Be extremely careful not to dent or damage the piping
while bending them away from the unit. Any dents in the
piping will affect the unit’s performance.
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. To ensure proper
drainage, attach the drain hose on the same side that your
refrigerant piping exits the unit. Attach drain hose extension
(purchased separately) to the end of drain hose.
• Wrap the connection point firmly with teflon tape to ensure
a good seal and to prevent leaks.
• For the portion of the drain hose that will remain indoors,
wrap it with foam pipe insulation to prevent condensation.
• 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.
