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
∆n
series 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.
