* If the height from the floor to ceiling exceeds three meters, air flow distribution deteriorates and the effect is decreased.
WARNING
4. The installation position must be able to support a load four times the indoor unit weight.
5. The indoor unit must be away from heat and steam sources, but avoid installing it near an entrance.
6. The indoor unit must allow easy draining.
7. The indoor unit must allow easy connection to the outdoor unit.
8. Place the indoor unit according to the height from the ceiling shown in the illustration below.
9. The indoor unit must be from at least 3m away from any noise-generating equipment. The electrical wiring must be shielded
with a steel conduit.
10. If the power supply is subject to noise generation, add a suppressor.
11. Do not install the indoor unit in a laundry. Electric shocks may result.
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, dispersing 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 the cooking room to install the air conditioner in such place where it may not suck in oily
steam.
2. Avoid installing the air conditioner in such circumstances where cutting oil mist or iron powder exist especially in
factories, etc.
3. Avoid places where inflammable gas is generated, flows-in, contaminated, or leaked.
4. Avoid places where sulphurous acid gas or corrosive gas can be generated.
5. Avoid places near high frequency generators.
