Step 5: For piping run outside the wall cavity, do the following: (if piping is run inside the wall cavity,
proceed to Step 6.
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 40mm 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. 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 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.
Step 6: Hook the indoor unit on the mounting plate:
Keep in mind that the hooks on the mounting plate are smaller than the holes on the back of the unit. In that case, you
don’t have ample room to connect embedded pipes to the indoor unit, the unit can be adjusted left or right by about
30-50mm, depending on the model.
