4 Special accessories
• BZ45U20 Pipe set: for use of the continuous-flow heater as an under
sink appliance.
• Priority switch (load shedding relay) BZ45L21:
for operation with the priority circuit.
• Mounting set BZ45K24M: for surface-mount installation.
• Truncated connecting piece sealed at rear for water connection from
below (e. g. cold water connection via fitting mounted below heater):

5 Operating instructions
Please read and observe the detailed safety instructions at the start
of these instructions!
• Important: The appliance may never be exposed to frost!
WARNING:
Risk of electric shock!
Switch off the mains voltage supply immediately if a fault occurs.
• Immediately shut off the cold water supply to the appliance should
it leak.
6 Getting to know your appliance
The continuous-flow heater heats the water as it flows through the
appliance. The appliance only consumes power during this period.
This appliance can supply hot water to taps in several different locations.
It should be installed close to the tap that is used the most frequently.
This will enable you to reduce energy consumption.

7 Operating the appliance
• Turn on the hot-water tap.
The continuous-flow heater switches on automatically and heats the
water as it flows through the appliance.
The heater switches off again when you turn off the tap.
7.1 Increasing the water temperature
When the tap is turned on fully, it is possible that the heater capacity is
not sufficient to heat the water to the required temperature.
• Turn the tap off slightly. The water flows through the appliance more
slowly and reaches a higher temperature as a result.
7.2 Decreasing the water temperature
• Mix with cold water.
7.3 Saving energy
To minimise energy consumption when turning off the hot water:
• Turn off the hot-water tap slowly in order to use the residual heat of
the continuous-flow heater.
• This also prevents the water temperature from briefly increasing
above the preselected temperature if the hot-water tap is turned on
again within the next few minutes.
To obtain particularly uniform hot-water temperatures, it is
recommended to use thermostatically-controlled premixers.
The thermostatically-controlled premixer must be suitable for
hydraulically controlled continuous-flow heater.
7.4 Winter operation
Note: It is possible in winter that the supply temperature of the water is
reduced and the required outlet temperature is no longer achieved.
