• If 48K Model is installed at a distance of 15m, 525g of
refrigerant should be added (15-7.5) x 70g = 525g
• Capacity is based on standard length and maximun
allowance length is on the basis of reliability.
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 capac-
ity 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 oil steam.
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.
