Manual Override Instructions:
◎In case of anelectric supply failure, it is possible to operate the actuator manually.
◎Power must in off position when start the manual override.
◎Gently putt up the knob about 3mm, then revolve the knob around left and right to control the valve open or close.
◎When the red needle in the indicator pointing to "S", means the valve is closed; When pointing to "O", means the valve is open.
◎After finish the manual override operation, must press down the knob, so that for the normal electric operation.
