DEAR CLIENT!
You have decided to purchase a water heating product with electric storage tank manufactured by us.
Thank you for your trust.
You have purchased an elegantly shaped device that represents the state of the art, that is in conformity with
the applicable rules and regulations. The sophisticated enamelling coat is the result of continuous research
and development efforts. Due to the constant quality checks during production, our hot water storage tanks
boast technical properties that you will appreciate anew every time. Because of the environmentally friendly
CFC-free insulation foam, the standby energy consumption is extraordinarily low. The ARA license lets you
return of packaging of your device, which will then be disposed of expertly to avoid environmental damage.
Installation and commissioning must be performed exclusively by an authorised installation company in accordance with these instructions.
In this small manual, you will nd all the information you will need for the proper installation and operation of
the device. Nevertheless, please ask your concessionaire to explain how the device works and to demonstrate how it is operated. Of course, our customer service and our sales department will be more than pleased
to assist you with any advice you may need.

SAFETY INSTRUCTIONS
General
• This tank can be used by children eight years old and older as well as by persons with reduced
physical, sensory or mental capabilities or who lack experience and knowledge if they are supervised or if they have been trained with regard to the safe use of the tank and understand the resulting risks. Children may not play with the tank or its packaging. Cleaning and user maintenance
may not be performed by children without supervision.
• The tank may only be installed and operated as described in this manual or the associated
technical information. Any other use is not proper and is therefore impermissible.
• A defective tank may not continue to be operated.
• There is a risk of scalding from hot water or hot components (e.g. ttings, hot water outlet pipe,
etc.).
• When using an electric immersion heater, proper corrosion protection is to be ensured.
Installation and commissioning
• Installation and commissioning may only be performed by qualied specialised personnel who
therefore assume the responsibility for the proper assembly according to the applicable laws,
standards and guidelines.
• The tank is mounted to a sufcient load-bearing wall using a wall mount (note the total weight of
the lled tank) or is placed on a at horizontal surface after mounting the included adjustable feet.
Ensure that the subsurface at the installation location has a sufcient load-bearing capacity.
• The tank may only be set up in dry, freeze-protected spaces. The tank is to be completely emptied if there is a risk of freezing.
• The rated pressure specied on the nameplate may not be exceeded.
• When installing the tank, a possible water leak is to be considered and a corresponding collection
container (including drain) is to be installed in a drainage object.
• Following the commissioning, the tank and all connections are to be checked for leak tightness.
Electrical Connection
• Only qualied specialised personnel may connect the tank to xed lines while observing the relevant professional standards and laws.
• A ground fault circuit interrupter with a trip current of I∆n ≤ 30mA must be installed upstream from
the electrical circuit.
• Before working on the tank, this is to be de-energised, checked for the absence of voltage and
secured against being switched on again.
• If a connection cable is damaged, immediately disconnect the power supply (circuit breaker) and
call a professional!
• Connection cables may not be extended or cut through in any way.
Servicing
• Maintenance, cleaning and any necessary repair or service work may only be performed by spe-
cialised personnel who are qualied for this purpose.
• Never try to x errors and faults yourself.
• Necessary service and maintenance intervals are to be observed in accordance with these operating and assembly instructions.

FUNCTION
The water stored in the enamelled interior tank is heated by an electrical heater insert. A user-adjustable
knob is available to preset the desired temperature. At the times determined by the responsible power
supply company, the temperature controller automatically switches on the heating. Once the desired
temperature in the storage tank is reached, the temperature controller switches the heater off again. If
the water temperature drops, for instance because water is used up or as a result of natural cooling (an
effect that is minimised by the high-quality CFC-free PU foam insulation), the heating will switch on until
the preset storage water temperature is reached again.
If the storage tank is equipped with a heater battery (EKR), the water may be heated with the system’s
water heater as an alternative to electrical heating.
HOT WATER REQUIREMENT
The hot water requirement of the household depends on the number of persons in the household, the
sanitary installations of the at or house, the insulation, the piping and the individual user’s habits.
The following table provides a list of standard consumption values for orientation.
In this table, it was assumed that the temperature of the cold water required for mixing to the indicated hot
water temperature is approximately 12°C.
ENERGY SAVING
The high-quality CFC-free PU foam insulation and the tted temperature control means that our electric
storage tanks are genuine energy savers.
Low storage water temperatures are especially economic. Therefore, the innitely variable temperature
setting should be set to the lowest value that is actually required to cover the real hot water requirement.
This helps save energy and reduces the build-up of limescale deposits in the tank.

STANDBY ENERGY CONSUMPTION
If no water is used for a long time after the end of the water heater’s heating interval, the water in the tank
will cool down slowly but continuously due to losses at the unit’s surface.
The speed of this cooling process depends on the type of device, its size, the thickness and the quality
of the tank insulation.
This behaviour is measured during a 24-hour period at a storage water temperature of 65°C, considering
the energy input in kWh that is necessary to keep the water temperature constant during this period.
Nominal content in litres 80 100 120 150 200
Standby energy consumption kWh/24h EKL 1,20 1,25 1,30 1,50 1,70
Standby energy consumption kWh/24h EKR 0,80 0,85 0,97
OPERATION
All operating elements required for the operation of the electric storage tank EKR (button to adjust the
temperature controller) and monitoring elements (operation indicator lamp and thermometer) are included
in a control panel on the front wall of the device.
Wall-mounted storage tank EKL do not have an operation indicator lamp and the button to adjust the
temperature controller of the horizontal storage tank is located on the front (connection side).
This tank can be used by children eight years old and older as well as by persons with reduced physical,
sensory or mental capabilities or who lack experience and knowledge if they are supervised or if they have
been trained with regard to the safe use of the tank and understand the resulting risks. Children may not
play with the tank or its packaging. Cleaning and user maintenance may not be performed by children
without supervision.
TEMPERATURE SETTING
As a setting aid, the adjusting knob of the electric heater’s temperature controller has 4 main stages,
namely:
up to 30 °C Frost protection for the tank
approx. 40 °C Hand warm tank water
approx. 65 °C Moderately hot tank water
approx. 85 °C hot tank water
Caution:
The adjusting knob at the left limit stop does not result in an off position or shutdown of the device heating.
The water may still have a temperature of 30 °C when operated in the frost protection position.
The temperature controller should not be set to a higher position than (approx. 65 °C) when operated
using day current. This position is recommended to rule out unintentiona scalding by excessively hot
water. The device operates particularly economically at this setting. The heat losses are minor and the
formation of boiler scale is largely avoided. Low standby energy consumption.
Due to the hysteresis of the temperature controller (± 7 K) and possible radiation losses (cooling of the
pipeline), the temperature specications are subject to an accuracy of ± 10 K.
