|        | Turn off the water pump and cut off the water pump power source; close the stop valve in the pipeline, release the pressure of pipeline and cool the pipeline totally; if necessary, remove the electrical wiring from connection terminal. Before re-debugging the valve, it is required to mount the hand operated regulator or actuator correctly. |   |
