3.3 Drill wall hole for connective piping
You must drill a hole in the wall for refrigerant piping, the
drainage pipe, and the signal cable that will connect the
indoor and outdoor units.
1. Determine the location of the wall hole based on the
position of the mounting plate. Refer to Mounting Plate
Dimensions on the next page to help you determine the
optimal position. The wall hole should have a 65mm
(2.5in) diameter at least, and at a slightly lower angle to
facilitate drainage.
2. Using a 65mm (2.5in) or 90mm(3.54in) (depending on
models )core drill, drill a hole in the wall. Make sure that
the hole is drilled at a slight downward angle, so that the
outdoor end of the hole is lower than the indoor end by
about 5mm to 7mm (0.2-0.27in). This will ensure proper
water drainage.
3. Place the protective wall cuff in the hole. This protects
the edges of the hole and will help seal it when you finish
the installation process.
NOTE: When drilling the wall hole, make sure to avoid
wires, plumbing, and other sensitive components.

3.4 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. Groove has been made in the knock-out panel in order
to cut it conveniently. The size of the slot is determined by
the diameter of piping.
4. 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.
5. 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.
6. Based on the position of the wall hole relative to the
mounting plate, determine the necessary angle of your
piping.
7. Grip the refrigerant piping at the base of the bend.
8. Slowly, with even pressure, bend the piping towards
the hole. Do not dent or damage the piping during the
process.

NOTE: Refrigerant piping can exit the indoor unit from
four different angles:
• Left-hand side
• Left rear
• Right-hand side
• Right rear
