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. Refer to the Refrigerant Piping Connection section of this
manual for detailed instructions on pipe flaring and flare torque requirements,
technique, etc.
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. Use scissors to cut down the length of the insulating sleeve to reveal about 15cm
(6in) of the refrigerant piping. This serves two purposes:
• To facilitate the Refrigerant Piping Connection process
• To facilitate Gas Leak Checks and enable you to check for dents
4. 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.
5. Based on the position of the wall hole relative to the mounting plate, determine the necessary angle of your
piping.
6. Grip the refrigerant piping at the base of the bend.
7. Slowly, with even pressure, bend the piping towards the hole. Do not dent or damage the piping during the
process.
NOTE ON PIPING ANGLE
Refrigerant piping can exit the indoor unit from four different angles:
• Left-hand side
• Left rear
• Right-hand side
• Right rear
