If the electric wave of AM broadcasting is particularly weak, keep distances of 3m or more and use conduit tubes for power and transmission lines.
2
Water quality
Water containing high level of foreign materials may cause the corrosion of heat exchanger and piping or scale accumulation.
Use water satisfying “10-7-4 Water quality”.
3
Cooling tower
Use a closed type cooling tower without fail. (Open type tower cannot be used.)
4
Strainer
Install a strainer (an optional accessory) without fail at the inlet of water piping. (If sands, wastes, rust particles, etc. are mixed in the water
circulation system, damage to the plate type heat exchanger may be caused by the corrosion of metal materials and clogging of the heat
exchanger.)
5
The refrigerant R410A itself is nontoxic, nonflammable and is safe. If the refrigerant should leak however, its concentration may exceed the
allowable limit depending on room size. Due to this it could be necessary to take measures against leakage.
Refer to the chapter “Caution for refrigerant leaks”.
