tions carefully and observe them!
Important: The appliance may never be exposed to frost!

Operation
VI.
The small water heater heats and stores drinking water up to
approx. 85 °C.
Setting the water temperature
The required outlet temperature from 35 °C to 85 °C can
be set with the rotary selector switch.
or:
Set the required fixed outlet temperature (A):
Frost protection
I Approx. 38 °C (soft lock-in)
e Conserve energy approx. 60 °C (soft lock-in)
III Hot water approx. 85 °C
The pilot lamp lights up during heat up.
Water drips out of the tap with oversink appliances.
The appliance with be covered more quickly with limescale
at higher temperatures.
Tip: Set the rotary selector switch to "e" to operate the appli-
ance economically and to reduce the effects of limescale.
Note: If the appliance has not been used for an extended
period, e. g. during a holiday, allow the water to briefly heat
up to stage "III".
Limitation of the water temperature
Limit the outlet temperature to avoid scalding with hot water:
Set the rotary selector switch to " ".
Open the cover of the rotary selector switch.
Select between "I" = approx. 38 °C (B1) or "e" = approx.
60 °C (B2).
Close the cover.
Switching off
Set the rotary selector switch to " " (A). The heating is
switched off.

Drip stop
The drip stop function prevents expanding water from drip-
ping from the tap during heat up. If water is heated, the gas-
ses (air) dissolved in it will be released by the water.

en
Depending on the quantity of gas released – particularly
when a higher temperature is selected – it can force residual
water from the tap.
A
Pressure stop
The appliance features pressure switch off. The pressure
switch off indicates when the tap is clogged by limescale
(low or no flow). When water pressure exceeds 0.25 Mpa
(2.5 bar) it even detects if the appliance has been incorrectly
connected with the water line during initial installation.
The pressure switch off automatically shuts off the water
inlet and prevents rupturing of the tank.
It the pressure stop has tripped, a red pin will appear at the
top of the appliance (C1).
The fault must be corrected (see chapter "A fault,
what to do?").
After the fault has been corrected, the red pin can be
pushed back in easily (C2). The water inlet is now free.
Please contact customer service if this occurs repeatedly.
Important: Do not block the path of the pin (C1) with objects.
Cleaning
Do not use aggressive or abrasive cleaning detergents!
Do not use a steam cleaner.
Clean appliance externally with a mild cleaning agent.
Clean the dirt and lime scale deposits in the aerator filter.
Descaling
Descale the outlet pipe with commercially available des-
caling agent or vinegar.
Please observe the manufacturers warnings when
descaling.
If the water flows significantly slower when the tap is fully
opened, the small water heater and tap should be descaled
by a specialist. Otherwise, the pressure stop may trip due to
an unpermissible high pressure.
Maintenance
The following repairs and maintenance may only be carried
out by an authorised customer service representative to
avoid potential sources of danger.
The electrical mains supply and the water supply must be
shut off before all work on the appliance.
Exchange of the electrical connection cable
When the electrical cable is visibly damaged:
Switch off the device, unplug the mains plug and contact
customer service.
B Cleaning the inlet filter
When the flow of water is too low and the inlet filter in the
tap is descaled:
Contact customer service and get the inlet filter (D)
cleaned.
