NOTE:
• 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, dis-
persing 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 cut-
ting oil mist or iron powder is in suspension 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 generat-
ed.
5. Avoid places near high frequency generators.
