11 MALFUNCTIONS

WE RECOMMEND YOU TO CALL IMMEDIATELY THE ASSISTANCE SERVICE IF A MALFUNCTION DIF-

FERENT FROM THOSE HERE DESCRIBED IS FOUND.

Note: the following malfunctions do not refer to problems noticed in the installation phase, but ONLY on correctly

installed - and already functioning - devices.

With the Main Breaker on 1, the ON/OFF indicator light [Z1] DOES NOT TURN ON.

Cause: The plug is not correctly plugged.

The plug is defective. A qualified technician should substitute it.

Power in the socket is missing. Check that the breakers, the omnipolar switches and the

differentials (lifesavers) on the electric system are closed. If they aren’t, before closing them,

make sure that no one is making electric maintenance.

A protective fuse of the electric system is cut down. Find and eliminate the eventual cause of

overcharge. Substitute cut down fuses with others of the same kind.

The supply cable is defective. BEFORE, cut down electrical feeding at the socket by opening

the breaker above it, then disconnect the plug and call the Assistance Service.
