NOTE ON PIPING ANGLE
Refrigerant piping can exit the indoor unit from Left-rear side(when you’re facing the back of the
unit)
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
seperately) tot the end of the 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.

NOTE ON DRAIN HOSE PLACEMENT
Make sure to arrange the drain hose according to the following figures.
NOTE:
When the gas side connective pipe is
Φ
16mm(5/8in) or more, the wall hole should be 90mm(3.54in).
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. 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 con-
nective piping that will join the indoor and outdoor units. Refer to the Refrigerant Piping Connection
section of this manual for detailed instructions.

CORRECT
Make sure there are no
kinks ordent in drain hose to
ensure proper drainage.
NOT CORRECT
Kinks in the drain hose will
create water traps.
NOT CORRECT
Kinks in the drain hose will
create water traps.
NOT CORRECT
Do not place the end of the
drain hose in water or in
containers that collect water. This
will prevent proper drainage.
