2. Safety
2.1 Intended use
The appliance is intended for domestic use. It can be used safely
by untrained persons. The appliance can also be used in non-do-
mestic environments, e.g. in small businesses, as long as it is
used in the same way.
This appliance is designed to heat DHW. The appliance is designed
for one hand washbasin.
Any other use beyond that described shall be deemed inappro-
priate. Observation of these instructions and of the instructions
for any accessories used is also part of the correct use of this
appliance.
2.2 General safety instructions
DANGER Scalding During operation, the tap can reach temperatures in
excess of 50 °C. There is a risk of scalding at outlet tem-
peratures in excess of 43°C.
!WARNING Injury
The appliance may be used by children aged3 and older
and persons with reduced physical, sensory or mental
capabilities or a lack of experience and know-how, pro-
vided that they are supervised or they have been in-
structed on how to use the appliance safely and have
understood the potential risks. Children must never play
with the appliance. Cleaning and user maintenance must
not be carried out by children without supervision.
DANGER Electrocution Any damaged power cables must be replaced by a qual-
ified electrician. This prevents potential hazards from
arising.
!Material losses
Protect the appliance and tap against frost.
!Material losses
Only use the special aerator provided. Prevent scale
build-up at the tap outlets (see chapter "Cleaning, care
and maintenance").

OPERATION
Appliance description
3. Appliance description
The hydraulically controlled mini instantaneous water heater
heats the water directly at the draw-off point. The heating system
starts automatically when the tap is opened. The short pipe runs
ensure that energy and water losses are minimal.
The DHW output depends on the cold water temperature, the heat-
ing output and the flow rate.
The bare wire heating system is suitable for hard and soft water
areas. This heating system has a low susceptibility to scale build-
up. The heating system ensures quick and efficient DHW provision
at the hand washbasin.
Fitting the special aerator supplied provides an optimum water jet.
4. Settings
The appliance heating system switches on automatically as soon
as you open the DHW valve at the tap or activate the sensor of a
sensor tap. The water is heated. The water temperature can be
adjusted at the tap:
For the starting flow rate, see chapter "Specification/ Data table/
On".
Increasing the temperature
 Reduce the flow rate at the tap.
Reducing the temperature
 Open the tap further or add more cold water.
Following an interruption to the water supply
See chapter "Commissioning/ Recommissioning".
5. Cleaning, care and maintenance
 Never use abrasive or corrosive cleaning agents. A damp
cloth is sufficient for cleaning the appliance.
 Check the taps regularly. Limescale deposits at the tap out-
lets can be removed using commercially available descaling
agents.
 Have the electrical safety of the appliance regularly checked
by a qualified contractor.
 Regularly descale or replace the special aerator (see chapter
"Appliance description/Accessories").

Troubleshooting
6. Troubleshooting
Problem Cause Remedy
The appliance will not
start despite the DHW
valve being fully open.
No power at the appli-
ance. Check the fuse/MCB in your fuse box/distribu-
tion board.
The aerator in the tap is
scaled up or dirty. Clean and/or descale the aerator or replace the
special aerator.
The water supply has been interrupted. Vent the appliance and the cold water inlet line
(see chapter "Settings").
If you cannot remedy the fault, notify your qualified contractor.
To facilitate and speed up your request, provide the number from
the type plate (000000-0000-00000).

supply pipe.
26�02�05�0065�
14.3 Tests in accordance with VDE0701/0702
Earth conductor check
 Check the earth conductor (in Germany e.g. DGUV A3) on the
earth conductor contact of the power cable and on the appli-
ance connector.
Insulation resistance
 If an appliance with a rated heating output of >3.5kW does
not achieve an insulation resistance of 300kΩ, we recom-
mend that the insulating properties of the appliance are
checked by conducting a differential current test of the earth
conductor current/leakage current to VDE0701/0702 (Fig.
C.3b).
14.4 Appliance storage
 Store the dismantled appliance free from the risk of frost, as
water residues remaining inside the appliance can freeze and
cause damage.
14.5 Replacing the power cable for the EIL6Plus
 If replacing the cable for the EIL6Plus, use a power cable
with 4mm² cross-section
