INDOOR UNIT INSTALLATION
Piping outlet
Cable outlet
A hole in the wall should be drilled for
refrigerant piping, the drainage pipe and
connecting cables that connect the
indoor and outdoor units.
DRILL WALL HOLE
1. Determine the location of the wall
hole based on the position of the
mounting plate.
2. Drill a hole in the wall at least the
diameter indicated (see Mounting
Plate Dimensions). 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. This will
ensure proper water drainage.
3. Place the pipe protection ring in the
hole. This protects the edges of the
hole and will help seal it when you
finish the installation process.

CAUTION
When drilling the wall hole, make sure to
avoid wires, plumbing and other
sensitive components.
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.
PRE
PARE REFRIGERANT PIPING
Refrigerant piping can exit the indoor unit
from four different angles: Left-hand side.
Left rear. Right-hand side. Right rear.
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.
NOTE ON PIPING ANGLE
CAUTION
Be extremely careful not to dent or
damage the piping while bending them
away from the unit. Any kinks in the
piping will affect the unit's performance.
