SPECIAL INFORMATION
- The appliance may be used by children aged8
and up and persons with reduced physical, sen-
sory or mental capabilities or a lack of experience
and know-how provided that they are supervised
or they have been instructed on how to use the
appliance safely and have understood the result-
ing risks. Children must never play with the ap-
pliance. Children must never clean the appliance
or perform user maintenance unless they are
supervised.
- Only use a permanent connection to the power
supply. The appliance must be able to be sepa-
rated from the power supply by an isolator that
disconnects all poles with at least 3mm contact
separation.
- The power cable must only be replaced (for
example if damaged) with the original spare
part by a qualified contractor authorised by the
manufacturer.
- Fix the appliance in position as described in the
chapter "Installation/ Preparations".
- Observe the minimum and maximum water inlet
pressure (see chapter "Specification/ Data table").
- The appliance is under pressure. During the heat-
up process, expansion water will drip from the
safety valve.
- Regularly activate the safety valve to prevent
it from becoming blocked e.g. by limescale
deposits.
- Drain the appliance as described in the chap-
ter "Installation/ Maintenance/ Emptying the
appliance".

SPECIAL INFORMATION
- Install a type-tested safety valve in the cold water
supply line. For this bear in mind that, depending
on the static pressure, you may also need a pres-
sure reducing valve.
- Size the drain so that water can drain off unim-
peded when the safety valve is fully opened.
- Fit the discharge pipe of the safety valve with
a constant downward slope and in a room free
from the risk of frost.
- The safety valve discharge aperture must remain
open to the atmosphere.

 This symbol indicates that you have to do something. The ac-
tion you need to take is described step by step.
1.3 Units of measurement
Note
All measurements are given in mm unless stated oth-
erwise.
2. Safety
2.1 Intended use
The appliance is intended for heating domestic hot water and can
supply one or more draw-off points.
This appliance is intended for domestic use. It can be used safely
by untrained persons. The appliance can also be used in a non-do-
mestic environment, e.g. in a small business, as long as it is used
in the same way.
Any other use beyond that described shall be deemed inappro-
priate. Using the appliance for heating fluids other than water or
water supplemented with chemicals, such as brine, is also deemed
inappropriate.
Observation of these instructions and of instructions for any ac-
cessories used is also part of the correct use of this appliance.
2.2 General safety instructions
WARNING Burns
During operation, the tap and safety valve can reach
temperatures in excess of 60°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 aged 8 and up and
persons with reduced physical, sensory or mental capa-
bilities or a lack of experience and know-how provided
that they are supervised or they have been instructed
on how to use the appliance safely and have understood
the resulting risks. Children must never play with the
appliance. Children must never clean the appliance or
perform user maintenance unless they are supervised.
!
Material losses
The user should protect the water lines and the safety
valve from frost.
Note
The appliance is under pressure. During the heat-up
process, expansion water will drip from the safety valve.
 If water continues to drip when heating is complet-
ed, please inform your qualified contractor.
2.3 CE designation
The CE designation shows that the appliance meets all essential
requirements according to the:
- Electromagnetic Compatibility Directive
- Low Voltage Directive
2.4 Test symbols
See type plate on the appliance.
3. Appliance description
The closed (pressure-tested) appliance heats DHW electrically.
You can adjust the temperature using the temperature selector.
Subject to the power supply, the water is heated automatically to
the required temperature.
The internal steel cylinder is coated with special "Co Pro" enamel
and is equipped with a protective anode. The anode protects the
internal cylinder from corrosion.
Frost protection
The appliance is also protected against frost by the temperature
setting "*", provided that the power supply is guaranteed. The
appliance switches on in good time and heats the water. The ap-
pliance does not protect the water supply lines and the safety
valve from frost.

E Recommended energy saving position, low scaling, 60°C
Max Maximum temperature setting, 75°C
Depending upon the system, the actual temperatures may vary
from the set value.
ON/OFF indicator
The ON/OFF indicator illuminates when water is being heated.
4.1 Holiday and absence
 If the appliance is not to be used for a few days, set the tem-
perature selector to a position between the frost protection
and energy saving settings.
 If the appliance is not to be used for a longer period, set it to
frost protection to conserve energy. If there is no risk of frost
you may disconnect the appliance from the power supply.
 For reasons of hygiene, heat up the content of the water
heater once to above 60°C before initial use.
5. Cleaning, care and maintenance
 Have the electrical safety of the appliance and the function of
the safety valve regularly checked by a qualified contractor.
 Have the protective anode initially checked by a qualified
contractor after the first year. The qualified contractor will
then determine the intervals at which it must be checked
thereafter.
 Never use abrasive or corrosive cleaning agents. A damp
cloth is sufficient for cleaning the appliance.
Scaling
 Almost every type of water will deposit lime at high temper-
atures. This settles inside the appliance and affects both the
performance and service life. The heating elements must
therefore be descaled from time to time. A qualified contrac-
tor who knows the local water quality will tell you when the
next service is due.
 Check the taps/valves regularly. You can remove limescale
deposits at the spouts using commercially available descaling
agents.
 Regularly activate the safety valve to prevent it from becom-
ing blocked e.g. by limescale deposits.
6. Troubleshooting
Problem Cause Remedy
The water does not heat
up and the ON/OFF indi-
cator does not illuminate.
There is no power. Check the fuses/MCBs in
your fuse box.
The water does not heat
up sufficiently and the
ON/OFF indicator illumi-
nates.
The temperature is set
too low.
Select a higher temper-
ature.
The appliance heats,
for example, after large
amounts of DHW have
been drawn.
Wait until the ON/OFF
indicator goes out.
The flow rate is low. The aerator in the tap or
shower head is scaled up
or contaminated.
Clean and/or descale the
aerator or shower head.
If you cannot remedy the fault, notify your qualified contractor. To
facilitate and speed up your enquiry, please provide the numbers
from the type plate (000000 and 0000-000000):
E-NO.: 000000
F-NO.: 0000-000000
