Drill the hole for anchor bolt on the wall.

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.
