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.

ENGLISH

OPERATION
Appliance description
!Material losses
Ensure that the non-pressurised appliance is not exposed
to any pressure as this could cause irreparable damage:
 Only use the special aerator provided.
 Never use aerators or hoses with aerators.
 Never seal the tap outlets.
 Prevent scale build-up at the tap outlets (see chapter
"Cleaning, care and maintenance").
2.3 Test symbols
See type plate on the appliance.
3. Appliance description
The hydraulically controlled, non-pressurised 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".

OPERATION
Cleaning, care and maintenance
8| EIL Trend www.stiebel-eltron.com
5. Cleaning, care and maintenance
 Never use abrasive or corrosive cleaning agents. A damp
cloth is sufficient for cleaning the appliance.
!Material losses
Scale build-up at the tap outlets can put the appliance
under pressure and may cause irreparable damage.
 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").
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).

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.
!Material losses
Observe the max. permissible inlet temperature. Higher
temperatures may damage the appliance. You can limit
the inlet temperature by installing a central thermostatic
valve.
!Material losses
Only operate the appliance with non-pressurised taps.
7.2 Instructions, standards and regulations
Note Observe all applicable national and regional regulations
and instructions.
The specific electrical resistance of the water used 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
"Specification/ Data table"). Your water supply utility will advise
you of the electrical resistivity or conductivity of the water in your
area.

INSTALLATION
Appliance shutdown
12. Appliance shutdown
 Isolate the appliance from the power supply by means of the
fuse/MCB in your fuse box or by pulling the power cable plug
from the socket.
 Drain the appliance (see chapter "Maintenance").
13. Troubleshooting
Problem Cause Remedy
The appliance will not
start despite the DHW
valve being fully open.
The aerator in the tap is
scaled up or dirty. Clean and/or descale the aerator or replace the spe-
cial aerator.
The sieve in the cold water
line is blocked. Clean the sieve after shutting off the cold water
inlet line.
The heating system is
faulty.
Check the resistance of
the heating system and
replace the appliance if
required.
14. Maintenance
DANGER Electrocution Before any work on the appliance, disconnect all poles
from the power supply.
14.1 Draining the appliance
DANGER Scalding Hot water may escape during draining.
If the appliance needs to be drained for maintenance or to protect
the whole installation when there is a risk of frost, proceed as
follows:
 Close the shut-off valve in the cold water inlet line.
 Open the draw-off valve.
 Undo the water connections on the appliance.

14.2 Clean strainer
You can clean the fitted strainer after removing the cold water
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Trend
 If replacing the cable for the EIL6Trend, use a power cable
with 4mm² cross-section.
