Noets：1) When the operation pressure is lower than the values in the table above, the
motor of the pump may be damaged because of large water flow.
2) When the operation pressure is higher than the vaues in the table above, the
water flow may be insufficient and the machine may need a pump replacement to
ensure high pressure.
3) Turn on the compressor.
4) Set process water temperature (Neglect this step if temperature is already
set). Press to increase or decrease water temperature. For this series
of water chiller, process water temperature should be set as 7℃ (never set
