2. Ceiling opening dimensions and hanging bolt location
• The dimensions of the paper model for installing are
the same as those of the ceiling opening dimen-
sions.
CAUTION
• This air-conditioner uses a drain pump.
• Horizontly install the unit using a level gauge.
• During the installation, care should be taken not to
damage electric wires.
• Select and mark the position for fixing bolts and piping hole.
• Decide the position for fixing bolts slightly tilted to the drain
direction after considering the direction of drain hose.
• Drill the hole for anchor bolt on the wall.
NOTE:
• Thoroughly study the following installation locations:
1. In such places as restaurants and kitchens, considerable amount of oil steam and flour adhere to the turbo
fan, the fin of the heat exchanger and the drain pump, resulting in heat exchange reduction, spraying, dis-
persing of water drops, drain pump malfunction, 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 oily 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.
