Reason:

(1) The secondary water temperature is above 40°C.

(2) Secondary water level is decreasing.

(3) Abnormal flow rate of primary water

(4) Abnormal secondary water flow rate

(5) Abnormal primary water pressure

(6) Leakage in the heat exchanger

(7) Leakage in the shaker

Solution:

(1) Check whether the cooling tower is operating normally and whether the primary water and secondary water valves are open.

(2) Check the amount of water in the tank and confirm that there is no water leakage from the water piping or shaker.

(3) Check whether the cooling tower is operating normally.

(4) Adjustment of the valve in the heat exchanger or replacement of the pump is required.

(5) Check whether the cooling tower is operating normally.

(6) Check if there is any water leakage inside the heat exchanger.
If there is water leakage, wipe it off and restart the machine. If it recurs immediately after restarting the machine, the heat exchanger parts need to be replaced.

(7) Check for water leakage from inside the shaker.
