When the gas side connective pipe is ⌀16mm(5/8in) or more, the wall
hole should be 90mm(3.54in).
Step 3: Drill wall hole for connection
You must drill a hole in the wall for refrigerant piping, the drainage pipe, and the
signal/power 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) 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 (0.2-0.275in). This will
ensure proper water drainage. (See Fig. 4)
3. Place a protective wall sleeve (not included) in the hole. This protects the
edges of the hole and will help seal it when you finish the installation process.
CAUTION: ELECTRICAL SHOCK/PROPERTY DAMAGE
When drilling the wall hole, make sure to avoid wires,
plumbing, and other sensitive components.

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 different angles:
Left-hand side
Left rear
Right-hand side
Right rear
Refer to Figure 9 for details.
Figure 9
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 difficult to remove by hand.
Figure 10
Knock-Out Panel
3. Slide the insulation back to expose the connection fittings. 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. Use the holder at the back of the unit to prop up the unit, giving you enough
room to connect the refrigerant piping, signal cable, and drain hose.

wall, proceed to Step 4.
2. Double-check that the ends of the refrigerant pipes are sealed to prevent
dirt or foreign materials from entering the pipes.
3. Carefully pass the wrapped bundle of refrigerant pipes, drain hose, and
signal/power wire through the hole in the wall.
4. Hook the top of the indoor unit on the upper hook of the mounting plate.
5. Check that unit is hooked firmly on the mounting plate by applying slight
pressure to the left and right-hand sides of the unit. The unit should not
jiggle or shift.
6. Using even pressure, push down on the bottom half of the unit. Keep
pushing down until the unit snaps onto the hooks along the bottom of the
mounting plate.
7. Again, check that the unit is firmly mounted by applying slight pressure to
the left and the right-hand sides of the unit.
