NOTE:
• Th roughly study the following installation locations:
1. In places such as restaurant and kitchen, considerable amount of oil steam and flour adhere to the fan, the fins of the heat
exchanger, resulting in heat exchange reduction, spraying, dispersing of water drops, etc.
In such 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 f rom 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 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 generated.
5. Avoid places near high frequency generators.
