To Maintain Efficient and Trouble-Free Performance
CAUTION
● The working water for this product is clean water (according to the water quality standard
set by the Japan Refrigeration and Air Conditioning Industry Association (see page 27 for
details)) or a water solution of 30 to 40 % concentration of industrial-use ethylene glycol.
Alternatively, if RO treated (deionized) is used, the water should have an electrical
conductivity of at least 1 μS/cm (low-purity). Only use with designated waters. Cooling
non-approved fluids can result in product damage, leaking, and possible electric shock or
electrical shorts.
1. If groundwater is to be used, have the groundwater checked and only use water that falls within the
indicated water standards.
2. When using RO treated (deionized) water, use water that has an electrical conductivity of at least 1
μS/cm (low purity). Operating on water that has a low conductivity value (high purity) can lead to
breakdown of the evaporator and/or pump. In addition, even if within normal operating ranges,
there would be no protection from metal ions being discharged from pipe fittings in the product.
(However there would be no problem regarding the mechanical strength of the product.)
