INSTALLATION
- Electrical work must be installed by a licensed electrician. Be sure to use the correct rating of the power plug and main circuit for the model to be installed.
- Incorrect installation due to ignoring of the instruction will cause harm or damage.
INSTALLATION ON CEILING
- Measure and mark the position for the Suspension bolts and the piping hole.
- Drill the hole for anchor nut on the ceiling.
- Drill the Piping hole slightly tilted to the outdoor side with a Ø 70 hole-core drill.
- Insert the nuts and washers onto the suspension bolts for locking the Suspension bolts on the ceiling.
- Mount the suspension bolts to the anchor-nuts firmly as shown in the diagram.

INSTALLATION ON THE WALL
The
centre of installation plate should be at more than 710 mm at right and left of
the wall. The distance from
installation plate edge to floor should more than 425 mm.
From
installation plate left edge to unit’s left side is 76 mm.
From
installation plate right edge to unit’s right is 76 mm.
- Mount the installation plate on the wall with 3 screws or more. (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.
- Drill the piping plate hole with ø70 mm hole-core drill.
- Drill the piping hole slightly slanted to the outdoor side.
TO DRILL A HOLE IN THE WALL AND INSTALL A SLEEVE OF PIPING
- Insert the piping sleeve to the hole.
- Fix the bushing to the sleeve.
- Cut the sleeve until it extrudes about 15 mm from the wall.
- Finish by sealing the sleeve with putty or caulking compound at the final stage.
Caution
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.
INDOOR UNIT INSTALLATION
- Remove 2 screws from the left and right corners.
- Pull the upper left and right side of the intake grille toward you, and it will stop at slightly tilted position.
- Remove 2 screws .
- Remove 3 screws cap, then remove 3 screws .
- Release 3 hooks as shown in the diagram.
- Lift up the front grille.
INSTALLATION ON CEILING
INSTALLATION ON THE WALL
CONNECTING CABLES TO INDOOR UNIT
- Open the control box at the bottom end of the chassis and connect the cable through the hole.
- Connect the wires to the terminals on the control board individually according to the outdoor unit connection.
- Ensure the color of wires of outdoor unit and the terminal Nos are the same to the indoor’s respectively.
- Secure the cable onto the control board with the holder (clamper).
- Insert two tabs on the Side panel into two slots on the chassis, and secure it to the chassis with the screw.
PIPING AND DRAINAGE
- Cut off the Chassis with a nipper according to the inner surface for the Pipings.
- Align the center of the pipings and sufficiently tighten the flare nut with fingers.
- Finally tighten the flare nut with torque wrench, ensure the direction for tightening follows the arrow on the wrench.
- Wrap the tube joining areas with insulating material so that there are no gaps (if it overlaps, cut the excess material)
EVACUATION OF THE EQUIPMENT (FOR EUROPE & OCEANIA DESTINATION)
WHEN
INSTALLING AN AIR CONDITIONER, BE SURE TO EVACUATE THE AIR INSIDE THE INDOOR
UNIT AND PIPES in the following procedure.
- Connect a charging hose with a push pin to the Low and High 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.
- Connect the center hose of the charging set to a vacuum pump with check valve, or vacuum pump and vacuum pump adaptor.
- 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.
- Close the valve at the charging set and turn off the vacuum pump. Make sure that the needle in the gauge does not move after approximately five minutes.
Note:
BE SURE TO TAKE THIS PROCEDURE IN ORDER TO AVOID REFRIGERANT GAS LEAKAGE.
- Disconnect the charging hose from the vacuum pump and from the service port of the 3-way valve.
- Tighten the service port caps of both of the 3-way valves at a torque of 18 N·m with a torque wrench.
- Remove the caps of both of the 3-way valves. Position both of the valves to “OPEN” using a hexagonal wrench (4 mm). 8. Mount caps onto both of the 3-way valves.
- Be sure to check for gas leakage.
CAUTION
- If gauge needle does not move from 0 cmHg (0 MPa) to -76 cmHg (-0.1 MPa), in step 3 above take the following measure:
- If the leak stops when the piping connections are tightened further, continue working from step 3.
- If the leak does not stop when the connections are retightened, repair the location of leak.
- Do not release refrigerant during piping work for installation and reinstallation. Take care of the liquid refrigerant, it may cause frostbite.
