INSTALLATION INSTRUCTIONS
Step 4: Prepare Refrigerant Piping
The refrigerant piping is inside an insulating sleeve attached to the back of the
unit. The piping must be prepared before passing it through the hole in the wall.
Refer to the Refrigerant Piping Connection section for detailed instructions on
pipe fl aring and fl are torque requirements, 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, leave 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 the side of the unit. This will create a slot through which the piping can
exit the unit. Use needle nose pliers if the plastic panel is diffi cult to remove.
3. Use scissors to cut down the length of the insulating sleeve to reveal
approximately 15 cm (6 in) of the refrigerant piping. This serves two
purposes:
• To facilitate the Refrigerant Piping Connection process
• To facilitate gas leaks checks and allow a check for dents in the pipe
4. If existing connective piping is already embedded in the wall, proceed directly to Step 5: Connect The
Drain Hose. 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.
5. Based on the position of the wall hole relative to the mounting plate, determine the necessary angle of
the piping. Grip the refrigerant piping at the base of the bend.
6. Slowly, with even pressure, bend the piping toward the wall hole. Do not dent or damage the pipe
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
• Left 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.
