3. Appliance description
The electronically controlled instantaneous water heater main-
tains a constant outlet temperature up to its output limit, irre-
spective of the inlet temperature.
The appliance heats the water directly at the draw-off point, as
soon as you turn on the hot water tap. The short pipe runs ensure
that energy and water losses are minimal.
For the start flow rate, see chapter "Installation/ Specification/
Data table, On".
The DHW output depends on the cold water temperature, the
heating output, the flow rate and the selected set temperature.
Water will not be reheated if the maximum inlet temperature for
reheating is exceeded.
DHW temperature
The DHW outlet temperature can be variably adjusted.
Temperature limit / Anti-scalding protection
The maximum outlet temperature for the appliance can be limited
to 43°C. For this, contact your local heating contractor.
Heating system
The bare wire heating system has a pressure-tested plastic casing.
The heating system is suitable for (both) soft and hard water and
is largely resistant to scale build-up. This heating system ensures
rapid and efficient DHW availability.
Note
The appliance is equipped with an air detector that large-
ly prevents damage to the heating system. If, during op-
eration, air is drawn into the appliance, the appliance
shuts down for one minute, thereby protecting the heat-
ing system.

 Turn the temperature selector to the required position.
If the outlet temperature fails to reach the required level with the
tap fully open and the temperature selector set to maximum, then
more water is flowing through the appliance than can be heated
by the heating element.
 Reduce the flow rate at the tap.
4.1 Recommended settings
Thermostatic valve
If the appliance is being operated with a thermostatic valve, we
recommend setting the temperature on the appliance to maxi-
mum. The required temperature can then be set at the thermo-
static valve.
Following an interruption to the water supply
!
Material losses
To ensure that the bare wire heating system is not dam-
aged following an interruption to the water supply, the
appliance must be restarted taking the following steps.
 Disconnect the appliance from the power supply by
removing the fuses/tripping the MCBs.
 Open the tap for one minute until the appliance and
its upstream cold water inlet line are free of air.
 Switch the mains power back ON again.
4.2 Temperature limit / Anti-scalding protection
The maximum outlet temperature for the appliance can be limited
to 43°C. For this, contact your local heating contractor.
