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.

TK(TB) clamps, the motor lacks thermal protection and may break
– burn.
It is recommended to check the device/ speed controller by
connecting the heater directly to power supply.
If the casing is damaged, make photos of the box and device, and
and on the box are the same. If the device was damaged during
transport, it is necessary to write down an appropriate statement by
the driver, who delivered the damaged device.

The most important is to check whether the actuator responded
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.

measures the temperature, it should be calibrated (instructions in
the catalogue).
