CAUTION

In case that the unit is installed near the sea, the installation parts may be corroded by
salt. The installation parts (and the unit) should be taken appropriate
anti-corrosion measures.

• 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 place where noxious gas is
generated.

5. Avoid places near high frequency
generators.

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.

Piping material: Polyvinyl chloride pipe VP-25 and pipe
fittings

•

Be sure to install heat insulation on the drain piping.

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

• Feed water to the flexible drain hose and

• Be sure to check the drain pump for normal

• When the test is complete, connect the

Precautions when laying power wiring

Use round pressure terminals for connections to the power terminal block.

When none are available, follow the instructions below.

- Do not connect wiring of different thicknesses to the power terminal block. (Slack in the power wiring may cause
abnormal heat.)

- When connecting wiring which is the same thickness, do as shown in the figure below.

- For wiring, use the designated power wire and connect firmly, then secure to prevent outside pressure being
exerted on the terminal block.

- Use an appropriate screwdriver for tightening the terinal screws. A screwdriver with a small head will strip the
head and make proper tighterning impossible.

- Over-tightening the terminal screws may break them.
