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.
Refrigerant piping can exit the indoor unit from four diff erent angles:
 Left-hand side
 Left rear
 Right-hand side
 Right rear
Refer to Figure 9 for details.

Rear of indoor unit
NOTICE:
 Be extremely careful not to crimp or damage the piping
while bending them away from the unit. Any deformations in
the piping will affect the unit’s performance.
If there is no refrigerant piping embedded in the wall, do the following:
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. (See Figure 10). This will create a slot through which
your piping can exit the unit. Use needle nose pliers if the plastic panel is too
diffi cult 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 kinks in
the refrigerant and condensate tubing.
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 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. Carefully, with even pressure, bend the piping towards the hole. Do not kink
or damage the piping during the process.
