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.
Default 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. Contact a qualified technician for details.
