Water quality
Water containing high levels of foreign materials may cause
corrosion of heat exchanger and piping or scale accumulation.
Use water with specifications according to
.
Cooling tower
Use a closed type cooling tower. (Open type tower cannot be
used.)
Filter
Install the filter at the inlet of the water piping. (If sand, rust
particles, or any other contamination is mixed in the water
circulation system, damage to the plate heat exchanger may be
caused by the corrosion of metal materials and clogging of the
heat exchanger.)
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
"19. Caution for refrigerant leaks" on page 42
