If there is a water leak, there is a danger of electric shock. Ensure there is no water leak
from the cooling water piping. If the water pressure is too high, a leak may occur in the
cooling water line inside the compressor unit. Adjust and control the cooling water supply
pressure not to exceed the allowable upper limit (lower than 0.7MpG).
If water stain or some products accumulate in the water line inside the heat exchanger, heat
exchange effectiveness will be significantly reduced and helium gas temperature will rise,
this may shut down the compressor unit.
We employ the cooling water quality management standard of the Japan Refrigeration and
Air Conditioning Industry Association as a standard value of water quality for compressor
units. Please r
efer to “Section 3 Table 3-1 Recommended Cooling Water for Compressor”.
The upper limit of the compressor operating ambient temperature is 38
℃
. Do not use the
compressor in unsuitable environments such as dusty, highly humid environments and/or
places that are affected by strong electromagnetic waves. Keep electric terminals free
from dust to avoid electrical leakage and/or a short circuit.
1. Installation and maintenance of the product must be done by personnel in charge of the
equipment or servicing who are familiar with the product structure and risk associated
with the operation of the compressor.
2. Input power supply must be shut off before opening the cover of the compressor to avoid
the risk of electrical shock.
Also, parts of inside the compressor unit are still hot just after the compressor has been
stopped. Wait at least 15 minutes to open the cover to avoid the risk of burns.
