5. WATER SYSTEM
5.1 Water Regulating Valve
• This unit is equipped with a water regulating
valve to operate within wide water temperature
range. This water regulating valve
automatically controls the water flow rate to
stabilize the refrigeration system and it has an
adjusting bolt to adjust the valve opening
temperature.
5.2 Default Water Regulating Valve Setting and Operation Range
• Default setting of the valve opening temperature is 86 °F (30 °C) and marked on the valve
housing. If the entering water temperature is below 86 °F (30 °C), there is no loss of water while
the unit is not operating. Adjustment of this valve setting is required only when the unit will be
used under the following conditions.
Entering water temperature is below 68 °F (20 °C):
Valve setting must be adjusted to lower temperature to extend the life of the compressor.
Entering water temperature is above 86 °F (30 °C):
Valve setting must be adjusted to higher temperature to prevent wasted water.
< NOTE >
This adjustment expands the minimum water temperature range. Carefully control the operating
range.
CAUTION
Failure to adjust the water regulating valve or operating the unit with entering water temperature
below 68 °F (20 °C) without adjusting the valve setting may damage the unit and void the
warranty.
