2. Safety
2.1 Intended use
This appliance is suitable for heating domestic hot water or for
reheating preheated water. The appliance is designed for one hand
washbasin.
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.
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 up
to 55°C.
There is a risk of scalding at outlet temperatures in ex-
cess of 43°C.
!
WARNING Injury
The appliance may be used by children over 3 years of
age and persons with reduced physical, sensory or men-
tal capabilities or a lack of experience and expertise,
provided that they are supervised or they have been
instructed 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.
!
Property damage
Protect the appliance and the tap against frost.
!
Property damage
Only use the special aerator provided. Prevent scale
build-up at the tap outlets (see chapter "Operation/
Cleaning, care and maintenance").

OPERATION
Appliance description
3. Appliance description
The electronically controlled mini instantaneous water heater
maintains a constant outlet temperature up to its output limit,
irrespective of the inlet temperature.
This appliance has been set at the factory to the outlet tempera-
ture required for washing hands. Once this temperature has been
reached, the PCB automatically reduces the output. The output is
matched to the required temperature, this prevents the temper-
ature being exceeded.
The appliance heats the water directly at the draw-off point as
soon as 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.
Your qualified contractor can adjust the maximum temperature
and flow rate (see chapter "Installation/ Commissioning/ Set-
tings").
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 and flow rate limit, see chapter "Instal-
lation/ Specification/ Data table".
Increasing the temperature
f Reduce the flow rate at the tap.
Reducing the temperature
f Open the tap further. Add more cold water.
Following an interruption of the water supply
See chapter "Installation/ Commissioning/ Recommissioning".

OPERATION
Cleaning, care and maintenance
8| EIL Premium www.stiebel-eltron.com
5. Cleaning, care and maintenance
f Never use abrasive or corrosive cleaning agents. A damp
cloth is sufficient for cleaning the unit.
f Check the taps regularly. Limescale deposits at the tap out-
lets can be removed using commercially available descaling
agents.
f Have the electrical safety of the appliance regularly checked
by a qualified contractor.
f Regularly descale or replace the special aerator in the
tap (see chapter "Installation/ Appliance description/
Accessories").
6. Troubleshooting
Problem Cause Remedy
The appliance will not
start despite the DHW
valve being fully open.
No voltage 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 "Installa-
tion/ Commissioning/
Recommissioning").
The preferred tempera-
ture is not being reached.
The maximum tempera-
ture set inside the appli-
ance is too low.
Have your qualified con-
tractor adjust the maxi-
mum temperature.
The appliance has
reached its output limit.
Reduce the flow rate.
If you cannot remedy the fault, contact your qualified contractor.
To facilitate and speed up your enquiry, please provide the serial
number from the type plate (000000-0000-00000).

7. Safety
Only a qualified contractor should carry out installation, commis-
sioning, maintenance and repair of the appliance.
7.1 General safety instructions
We guarantee trouble-free function and operational reliability only
if original accessories and spare parts intended for the appliance
are used.
!
Property damage
Observe the maximum inlet temperature. Higher tem-
peratures may damage the appliance. You can limit the
maximum inlet temperature by installing a central ther-
mostatic valve.
WARNING Electrocution
This appliance contains capacitors which are discharged
when disconnected from the power supply. The capacitor
discharge voltage may briefly exceed >34VDC.
7.2 Instructions, standards and regulations
Note
Observe all applicable national and regional regulations
and instructions.
The electrical resistivity of the water must not fall below that stated
on the type plate. In a linked water network, factor in the lowest
electrical resistance of the water (see chapter "Installation/ Spec-
ification/ Data table"). Your water supply utility will advise you of
the electrical resistivity or conductivity of the water in your area.
