Note: Before the valve / actuator maintenance: - stop the pump and cut off the water pump power - close the valve - release the pressure in the piping system and allow pipes to cool completely necessary, disconnect the electrical wires of the actuator. Before commissioning the valve once again need to ensure that the actuator has been installed correctly.
