The user should protect the appliance and its tap against
frost.
3. Appliance description
The appliance switches on automatically as soon as you open the
hot water valve on the tap. When you close the tap, the appliance
switches off again automatically.
The appliance heats water as it flows through it. The DHW outlet
temperature can be variably adjusted. From a certain flow rate,
the control unit regulates the correct heating output, subject to
the temperature selected and the current cold water temperature.
The electronically controlled instantaneous water heater with au-
tomatic output matching maintains a consistent outlet tempera-
ture. It is irrespective of the inlet temperature, up to the maximum
output of the appliance.
If the appliance is operated with preheated water and the inlet
temperature exceeds the chosen set temperature, the water will
not be heated further.
You can set the temperature unit (°C or °F) according to prefer-
ence.
Heating system
The bare wire heating system is enclosed within a pressure-tested
plastic jacket. The heating system with its stainless steel internal
indirect coil is suitable for hard and soft water areas and is largely
insusceptible to scale build-up. The heating system ensures rapid
and efficient DHW provision.
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.

Your instantaneous water heater offers maximum precision and
maximum convenience in DHW provision. Should you nonetheless
be operating the appliance with a thermostatic valve, we recom-
mend that you:
f Adjust the set temperature on the appliance to over 50 °C. f
Saving energy
The following recommended settings will result in the lowest en-
ergy consumption:
- 38 °C for hand washbasins, showers, bath
- 55 °C for kitchen sinks
Internal anti-scalding protection (qualified contractors)
If required, the qualified contractor can set a permanent temper-
ature limit, for example in nurseries, hospitals etc.
When supplying a shower, the appliance temperature setting
range must be adjusted by the qualified contractor to 55 °C or less.
Limiting it in this way prevents water from flowing out of the
appliance at temperatures which could cause injury.

yourself in temperature unit selection mode. Then select the
temperature unit using the temperature selector. After 30 s,
the appliance exits selection mode automatically and the se-
lected temperature unit is retained.
Note
!
If the outlet temperature is not high enough when the
draw-off valve is fully open and the temperature selector
is set to maximum, then more water is flowing through
the appliance than can be heated by the heating system
(appliance working at maximum output).
