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.
