The mounting wall is strong and solid enough to prevent it from
the vibration.

The centre of installation plate should be at more than   at
right and left of the wall.
The distance from installation plate edge to ceiling should more

than .

From installation plate left edge to unit’s left side is  .

From installation plate right edge to unit’s right is  .
B : For left side piping, piping connection for liquid should be 

about   from this line.

: For left side piping, piping connection for gas should be 

about   from this line.

1. Mount the installation plate on the wall with 5 screws or

more (at least 5 screws).
(If mounting the unit on the concrete wall, consider using
anchor bolts.)

• Always mount the installation plate horizontally by

aligning the marking-off line with the thread and using a
level gauge.

2. Drill the piping plate hole with ø70 mm hole-core drill.

• Line according to the left and right side of the installation

plate. The meeting point of the extended line is the
center of the hole. Another method is by putting
measuring tape at position as shown in the diagram
above. The hole center is obtained by measuring the
distance namely 128 mm for left and right hole
respectively.

• Drill the piping hole at either the right or the left and the

hole should be slightly slanting to the outdoor side.

1. Insert the piping sleeve to the hole.
2. Fix the bushing to the sleeve.
3. Cut the sleeve until it extrudes about 15 mm from the

wall.

4. Finish by sealing the sleeve with putty or caulking

compound at the final stage.

When the wall is hollow, please be sure to use the sleeve 
for tube ass’y to prevent dangers caused by mice biting 
the connecting cable.

1. For the right rear piping

2. For the right and right bottom piping

3. For the embedded piping

(This can be used for left rear piping and bottom piping also.)

1. The inside and outside connecting cable can be

connected without removing the front grille.

2. Connecting cable between indoor unit and outdoor unit

shall be approved polychloroprene sheathed 4 x 1.5 mm

2

flexible cord, type designation 245 IEC 57 or heavier
cord.

• Secure the connecting cable onto the control board with

the holder (clamper).

 This equipment must be properly earthed.

• Ensure the colour of wires of outdoor unit and the terminal Nos. are the same to the indoor’s respectively.
• Earth wire shall be Yellow/Green (Y/G) in colour and longer than other AC wires for safety reason.

1. Please cut using pipe cutter and then remove the burrs.
2. Remove the burrs by using reamer. If burrs is not removed, gas leakage may be caused.

Turn the piping end down to avoid the metal powder entering the pipe.

3. Please make flare after inserting the flare nut onto the copper pipes.

28

• After selecting the best location, start installation according to Indoor/Outdoor Unit Installation Diagram.

1. Fix the unit on concrete or rigid frame firmly and horizontally by bolt nut (ø10 mm).
2. When installing at roof, please consider strong wind and earthquake. Please fasten the installation stand firmly with bolt or

nails.

Connecting the Piping to Indoor
Please make flare after inserting flare nut (locate at joint portion
of tube assembly) onto the copper pipe. 
(In case of using long piping)
Connect the piping

• Align the center of piping and sufficiently tighten the flare nut

with fingers.

• Further tighten the flare nut with torque wrench in specified

torque as stated in the table.

Connecting the Piping to Outdoor
Decide piping length and then cut by using pipe cutter. Remove
burrs from cut edge. Make flare after inserting the flare nut
(located at valve) onto the copper pipe.
Align center of piping to valve and then tighten with torque
wrench to the specified torque as stated in the table.

WHEN INSTALLING AN AIR CONDITIONER, BE SURE TO EVACUATE THE AIR INSIDE THE INDOOR UNIT AND PIPES in the
following procedure.

1. Connect a charging hose with a push pin to the Low side of a charging set and the service port of the 3-way valve.

• Be sure to connect the end of the charging hose with the push pin to the service port.

2. Connect the center hose of the charging set to a vacuum pump.
3. Turn on the power switch of the vacuum pump and make sure that the needle in the gauge moves from 0 cmHg (0 MPa) to

-76 cmHg (-0.1 MPa). Then evacuate the air approximately ten minutes.
