The connection with the power grid must be implemented in conformity with the applicable national
regulations and standards, the relevant connecting requirements of the local power company
and waterworks, as well as the standards of the Mounting and Operating Instructions, and must
be performed exclusively by a licensed electrician. The stipulated protective measures must be
executed carefully, so that no other power-supplied devices are affected thereby in the event of
a malfunction or failure of the hot water tank's power supply (e.g. freezer, rooms used for medical
purposes, units for intensive care, etc.).
In rooms with bathtubs or showers, the device must be installed in accordance with the national
laws and regulations (e.g. of ÖVE-SEV or VDE).
The technical connecting requirements (TAB) of the relevant energy supply company must absolutely
be observed.
A residual current circuit breaker with a tripping current I ≤30mA must be connected in series
∆n
before the electric circuit.
The device must only be connected with permanently laid lines.
An allpole disconnecting unit with at least 3mm contact clearance must be connected in series
before the device. This requirement is fulfilled e.g. by an automatic cutout.
It is imperative that the hot water tank is filled with water prior to electrical startup.
In accordance with the safety regulations, the hot water tank must be switched powerless,
secured against being switched on again and checked for powerlessness prior to any intervention.
Interventions to the electrics of the device must only be performed by a licensed electrician.
As a rule, the electrical connection must be performed in accordance with the circuit diagram affixed
inside the connecting area of the tank!
Version with contactor control –RSW types
ÖVE (Association of Austrian Electrical Engineers) or VDE (Association of German Electrical
Engineers) tested control contactors fitted outside the housing of the fitted heater, for instance
in a control cabinet of the fixed installation, must be used for installations and control contactors.
Separate control contactors must be used for the safety temperature limiter and the temperature
controller. The contactors must bear an inscription/label indicating their safety function for the water
heater. (TR and STB (security temperature limiter).
The output data for the choice of the contactors is given in the table (Section: Technical Data) in the
»Switching group« column. The STB (security temperature limiter) contactor must be designed for
the total output of the switching groups. When the installation has been completed, the function of
the contactors must be checked to ensure they work properly.

5.7 Commissioning

Commissioning: before the unit is switched on electrically for the first time, the tank must be filled
with water. As the water heats up, the expansion water produced in the inner boiler must drip from
the safety valve if the connection is pressureproof and from the overflow combination set if the
connection is unpressurised.
Caution: The hot water discharge pipe and parts of the safety fitting can get hot.
After the tank has heated up fully, the temperature setpoint, the actual temperature of the retrieved
water and the hot water quantity display should coincide roughly.
Should a device, at the point of delivery, clearly display a malfunction, damage or other defect, this
must not be fitted, installed or used in the system. Subsequent complaints regarding devices with an
obvious defect which have been connected and installed are expressly excluded under the warranty
and guarantee.
