• The dimensions of the paper model for installation are the same as those of the ceiling

opening dimensions.

• 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

places where cooking oil or iron

powder is generated.

3. Avoid places where inflammable gas

is generated.

4. Avoid places where noxious gas is

generated.

5. Avoid places near high frequency

generators.

NOTICE

CAUTION :

• This air-conditioner uses a drain

pump.

• Install the unit horizontally using a

level gauge.

• During the installation, care should

be taken not to damage electric

wires.

• Select and mark the position for fixing bolts

and piping hole.

• Decide the position for fixing bolts slightly

tilted to the drain direction after considering

the direction of drain hose.

• Drill the hole for anchor bolt on the wall.

Use the ventilation fan

for smoke-collecting

hood with sufficient

capacity.

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 in-

cluded the indoor unit box.

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.

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).

The decoration panel has its installa-

tion direction.

Before installing the decoration panel, al-

ways remove the paper template.

• 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 pip-

ing.

Piping material: Polyvinyl chloride pipe VP-25

and pipe fittings

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 exte-

rior 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 nor-

mal 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.

Heat insulation material: Polyethylene foam

with thickness more than 8 mm.
