If refrigerant piping is already embedded in
the wall, do the following:
Step 1:Hook the indoor unit on the mounting
plate:
Step 2: Prepare refrigerant piping:
1. Disassemble the louver:
Fig. 3.5
Move to left or right
30-50mm
(1.2-1.95in)
30-50mm
(1.2-1.95in)
1. Keep in mind that the hooks on the mounting plate
are smaller than the holes on the back of the unit.
If you find that 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 (1.25-1.95in),
depending on the model. (See Fig.3.4)
CAUTION
Be extremely careful not to dent or
damage the piping while bending them
away from the unit. Any dents in the
piping will affect the unit’s performance.
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.
NOTE ON PIPING ANGLE
Refrigerant piping can exit the indoor unit from
four different angles:
•
Left-hand side
•
Left rear
•
Right-hand side
•
Right rear
Refer to Fig. 3.3 for details.

2. Open and fix the position of the panel
Firstly, unscrew the two screws showed
in the picture below, then open the panel,
and fix the position of the panel by the
latch(see Fig.3.6).

If there is no refrigerant piping embedded in
the wall, do the following:

Step 3.
Connect drain hose and refrigerant
piping (refer to Refrigerant Piping Connection
section of this manual for instructions).
Step 4. Keep pipe connection point exposed to
perform the leak test (refer to Electrical Checks
and Leak Checks section of this manual).
Step 5. After the leak test, wrap the connection
point with insulation tape.
Step 6. Remove the bracket or wedge that is
propping with insulation tape.
Step 7. 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.
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
Fig. 3.8
). 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 (1.57in)
of the refrigerant piping. This serves two
purposes:
• To facilitate the Refrigerant Piping
Connection
process.
• To facilitage Gas Leak Checks and enable
you to check for dents

3. Use the holder in the mounting plate to
prop up the unit, giving you enough room
to connect the refrigerant piping, signal cable,
and drain hose.
