Where children or persons with limited physical, sensory or men-
tal abilities are allowed to use this appliance, we recommend a
permanent temperature limit. A qualified contractor can set this
limit.
!
Material losses
The user should protect the appliance and its tap against
frost.
!
Material losses
Never subject the appliance to water pressure. The tap
outlet has a vent function. Scale build-up can block the
outlet and subject the appliance to pressure.
Never seal the tap outlet.
Only use special aerators for non-pressurised water
heaters.
Never extend the tap outlet with a hose.
!
Material losses
Connecting the appliance via a time switch will cause an
unintentional reset of the high limit safety cut-out.
Never connect the appliance to the power supply via
a time switch.
2.3 Test symbols
See type plate on the appliance.
Information for Australia/New Zealand:
Installation complies with standard AS/NZS 3500.4.
3. Appliance description
The open vented (non-pressurised) appliance constantly maintains
the water content at the pre-selected temperature. During heating,
expansion water drips from the tap. The appliance may only be in-
stalled with taps for open vented (non-pressurised) water heaters
(see chapter "Installation/ Appliance description/ Accessories").
thermostop function
The thermostop function (thermal separation) prevents the tap
becoming hot in standby mode.

Depending on the system, the actual temperatures may vary from
the set value.
°C = Cold. On this setting, the appliance is protected from
frost. The tap and the water line are not protected.
Eco = Recommended energy saving setting (approx. 60°C),
minor scaling
85 = Highest selectable temperature
Note
A qualified contractor can set a temperature limit on the
appliance (see chapter "Installation/ Settings/ Setting
the temperature limit").
4. Cleaning, care and maintenance
Never use abrasive or corrosive cleaning agents. A damp
cloth is sufficient for cleaning the appliance.
Check the tap regularly. You can remove limescale deposits
at the outlet using commercially available descaling agents.
Almost every type of water will deposit lime at high temperatures.
This settles inside the appliance and affects both the performance
and service life. The heating elements should therefore be des-
caled if necessary. A qualified contractor who is aware of the
local water quality will tell you when the appliance should next
be descaled.
5. Troubleshooting
Problem Cause Remedy
The appliance does not
supply hot water.
The temperature se-
lector is set to “°C”.
Switch the appliance ON
by turning the temperature
selector.
No power at the ap-
pliance.
Check the plug and the
fuses/MCBs in the fuse box/
distribution panel.
Water can only be drawn
at a reduced rate.
The aerator in the tap
is scaled up.
Descale / replace the aer-
ator.
Loud boiling noises in-
side the appliance.
The appliance is scaled
up.
Have the appliance descaled
by a qualified contractor.
If you cannot remedy the fault, notify your qualified contractor.
