NOTICE
• Avoid the following installation location.
1. Such places as restaurants and kitchen where considerable amount of oil steam and flour is
generated.
These may cause heat exchange efficiency reduction, or water drops, drain pump mal-function.
In these cases, take the following actions;
• Make sure that ventilation fan is enough to cover all noxious gases from this place.
• Ensure enough distance from the cooking room to install the air conditioner in such a place
where it may not suck oily steam.
2. Avoid installng air conditioner in such

Installation
The decoration panel has its installation direction.
Before installing the decoration panel, always remove the paper template.
1. Temporarily fix two decoration panel fixing screws (hexagon M5 screw) on the unit body.
(Tighten by amount 10 mm in length.) The fixing screws (hexagon M5 screw) are included the indoor unit box.
2. Remove the air inlet grille from the decoration panel. (Remove the hook for the air inlet grille cord.)
3. Hook the decoration panel key hole (
) on the screws fixed in step above, and slide
the panel so that the screws reach the key hole edge.
4. Retighten completely two temporarily fixed screws and other two screws. (Total 4 screws)
5. Connect the louver motor connector and display connector.
6. After tightening these screws, install the air inlet grille (including the air filter).

Drain Piping
• Drain piping must have down-slope (1/50 to
1/100): be sure not to provide up-and-down slope
to prevent reversal flow.
• During drain piping connection, be careful not to
exert extra force on the drain port on the indoor
unit.
• The outside diameter of the drain connection on
the indoor unit is 32 mm.

• Be sure to install heat insulation on the drain piping.
MAX 700 mm
Heat insulation material: Polyethylene foam
with thickness more than 8 mm.
Drain test
The air conditioner uses a drain pump to drain water.
Use the following procedure to test the drain pump operation:

• Connect the main drain pipe to the exterior and leave it provisionally until the
test comes to an end.
• Feed water to the flexible drain hose
and check the piping for leakage.
• Be sure to check the drain pump for normal operating and noise when electrical
wiring is complete.
• When the test is complete, connect the
flexible drain hose to the drain port on
the indoor unit.

CAUTION : The supplied flexible

Installation
1) Never fail to have separate power specially for the air conditioner. As for the
method of wiring, follow the circuit diagram pasted on the inside of control
box cover.
2) Provide a circuit breaker switch between power source and the unit.
3) The screw which fasten the wiring in the casing of electrical fittings are liable
to come loose from vibrations to which the unit is subjected during the
course of transportation. Check them and make sure that they are all tightly
fastened. (If they are loose, it could give rise to burn-out of the wires.)
4) Confirm the Specification of power source
5) Confirm that electrical capacity is sufficient.
6) Be sure that the starting voltage is maintained at more than 90 % of the rated
voltage marked on the name plate.
7) Confirm that the cable thickness is as specified in the power sources specification.
(Particularly note the relation between cable length and thickness.)
8) Do not install the leakage breaker in a place which is wet or moist.
Water or moist may cause short circuit.
9) The following troubles would be caused by voltage drop-down.
• Vibration of a magnetic switch, damage on the contact point there of, fuse breaking, disturbance to the normal function of a overload protection device.
• Proper starting power is not given to the compressor.
HAND OVER
Teach the customer the operation and maintenance procedures, using the operation manual.
(air filter cleaning, temperature control, etc.)
