Level of operating noise of VOLCANO devices is perceived
subjectively. If the device is made of plastic, it should operate
quietly.It is recommended to unscrew the clamping screws and
tightening them up again. If the fault does not disappear, you should
make a complaint.

to the electric impulse within 11s. If the motor is damaged, you
need to make a complain and switch actuator operation to manual
(MAN), which mechanically opens the valve.
