cooling operation, the protection system may engage and stop the operation.
(4) After 5~10 minutes, fully close the 2-way valve by turning the hexagon socket screw key clockwise.
(5) After 2~3 minutes, immediately close the 3-way valve fully.
(6) Stop the test run operation.
(7) Replace both valve shaft caps tightly.
