Dear Customer,
Following your decision to purchase a hot water heater with an electric storage tank produced by our
company
We should like to thank you for selecting one of our products.
We are supplying you with an attractively designed product that is built according to the state-of-the-art
and which meets the currently applicable regulations. The highly developed enamelling process that is
the result of continuous research together with continuous quality inspections during production com-
bine to give our hot water storage tanks technical features which provide signicant benets for you.
Thanks to the environmentally friendly CFC-free insulating foam an extraordinarily low standby energy
consumption is guaranteed.
The installation and the initial commissioning may only be carried out by an authorised installation company as per these instructions.
This small brochure contains all of the important instructions for the correct assembly and operation.
Despite this, however, the functioning of the appliance should be explained to you and the servicing
carried out by your dealer. At the same time, please note that our company is at your disposal to give
advice on matters of customer service and sales.
We hope that you enjoy using your electrical storage unit.

1. Function
The domestic hot water stored in the enamelled inner boiler is heated by the electrical heating element.
The end-user can preselect the desired temperature on the setting toggle. The heating is switched on
independently by the temperature control system during the heating-up times that have been set by
the responsible electricity supply company and switched off after reaching the desired storage water
temperature.. Should the water temperature become lower, for example due to water being removed
or to natural cooling-down (the high quality CFC-free polyurethane foam insulation keeps this as low as
possible), then the heating system of the appliance switches itself back on until the pre-set storage tank
water temperature is reached.
2. Hot water requirement
The hot water requirements in the household depend on the number of persons, on the sanitary installations in the apartment or house, on the installation, on the piping and on the individual habits of the
consumers.
The following table gives some guidelines on consumption gures.
The temperature of the necessary cold water for mixing at the given hot water temperature has been
assumed as being approximately 12°C.
3. Energy-saving
Our electrical storage tanks are real energy savers as a result of the high quality .environmentally-friendly,
CFC-free polyurethane foam insulation and the built-in temperature control system.
Low storage water temperatures have proved to be particularly economical. Accordingly, the innitely
variable adjustable temperature should only be as high as the one that has been selected as being necessary for the actual hot water requirements. This helps save energy and reduces lime scale deposits
in the storage tank.

4. Standby energy consumption
If a water heater is heated-up and no water is removed for a lengthy period of time after completion of
the heating process, a somewhat slow but continuous cooling down of the stored water takes place
over the surface of the appliance.
The intensity and speed of this cooling-down process depend on the design of the appliance, as well as
on its size, thickness and the quality of the storage tank‘s insulation.
This behaviour over a period of 24 hours is measured at a storage water temperature of 65°C, with calculations being made of the energy expenditure in kWh that is necessary in order to maintain the water
temperature constant over this period of time.

5. Operation
The requisite operating devices needed to operate the electrical storage unit (temperature control system setting toggle) are located together on the front of the equipment.
This equipment is not suitable for use by persons (including children) with limited physical, sensory or
mental capabilities or those who lack experience and/or knowledge, unless they are being supervised
by someone responsible for their safety or have received instructions on how the equipment is to be
used. Children should be supervised to ensure that they do not play with the equipment.
6. Setting the temperature
To facilitate making adjustments, the adjusting toggle of the
temperature control unit of the electric heater has 4 main
settings, which are:
Setting: Frost protection for the storage tank (up to 30°C)
approx. 40°C, lukewarm storage water
approx. 60°C, moderately hot storage water
In order to avoid any accidental scalding with excessively
hot water, excluding this setting is recommended.
The equipment operates in a particularly economic manner at this setting.
The heat losses are low and the build-up of boiler scale is avoided to a large extent.
Lower standby energy consumption
approx. 80°C, moderately hot storage water
Warning:
The adjusting toggle on the left-hand end has no zero setting or off-switch for the heating of the appliance.
When operating with daytime current, the temperature control should not be set any higher than the
setting pos. (approx.60°C).
Based upon the hysteresis of the temperature control unit. (±7K) and possible radiation losses (cooling
down of the pipes), the temperature specications are subject to an accuracy of ±10K.
