3. Place the protective wall cuff in the hole. This protects
the edges of the hole and will help seal it when you finish
the installation process.
NOTE: When drilling the wall hole, make sure to avoid
wires, plumbing, and other sensitive components.

3.4 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.
3. If existing connective piping is already embedded in the
wall, proceed directly to the 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: Refrigerant piping can exit the indoor unit from
four different angles:
• Left-hand side
• Left rear
• Right-hand side
• Right rear
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.
3.5 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).
• Wrap the connection point firmly with Teflon tape to
ensure a good seal and to prevent leaks.
• 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 the
following figures.
