POSITION OF CONSOLE BOLT
• A place where the unit will be leveled and that can
support the weight of the unit.
• A place where the unit can withstand its vibration.
• A place where service can be easily performed.
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, 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 suc-
tion 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 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.
