IMPORTANT: DO NOT FORGET TO CONNECT THE GROUND!
The container must be fitted with water inlet and outflow tubes made from metal and other touchable metal
parts of the container which come into contact with water must be permanently and reliably connected to
ground. An all-pole disconnecting switch with 3 mm contact gaps must be fitted in the power supply feed. Auto-
matic circuit breakers are also acceptable as isolating switch mechanisms.
WATER CONNECTION
The installation, connection and user instructions for the water heater (boiler) are to be followed at all costs. In
the case of a pressurized connection, a certified membrane safety valve or a membrane safety valve combination
is required. In the case of an unpressurized connection, a return valve, a stop valve as well as service fittings for
unpressurized connections are required. The possibility of dry heating is to be avoided at all costs.
INITIAL OPERATION
The container must be filled with water before the electricity is turned on. The first-time
heating of the appliance must be monitored. During the heating process, the expanded water produced in the
interior boiler must drip from the safety valve in the case of a pressurized connection and from the overflow
mixing faucet in the case of an unpressurized connection. The automatic cutout function of the thermostat must
be checked.
When repair becomes necessary, only use original replacement parts!
