- Drill the hole for anchor bolt on the wall.

NOTE

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.
