NOTICE
• Throughly study the following installation locations:
1. In such places as restaurants and kitchens, considerable
amount of oil steam and flour adhere to the fan, the fin of
the heat exchanger, resulting in heat exchange reduction,
spraying, dispersing of water drops, etc.
In these cases, take the following actions:
• Make sure that the ventilation fan for smoke-collecting
hood on a cooking table has sufficient capacity so that it
draws oily steam which should not flow into the suction
of the air conditioner.
• Make enough distance from a cooking room to install
the air conditioner in such a place where it may not suck in oil steam.
2. Avoid installing air conditioner in such circumstances where cutting oil mist or iron powder is in sus-
pension in factories, etc.
3. Avoid places where inflammable gas is generated, flows in, is stored or vented.
4. Avoid places where sulfurous acid gas or corrosive gas is generated.
5. Avoid places near high frequency generators.
