• Rated performance for refrigerant line length of: 5m
• If 24K or 28K Model is installed at a distance of 15m, 500g of refrigerant
should be added ....................................................(15-5)x50g
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 a cooking room to install the air conditioner in such a place where it
may not suck in oily steam.
Air conditioner
2. Avoid installing air conditioner in such circumstances where cutting oil mist or iron powder is in sus-
pension 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.
