Commissioning - Austria Email REU Notice D'utilisation Et De Montage

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 before
∆n
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. Interven-
tions 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.
The entire initial heating process is to be monitored, from cold water to reaching the set temperature. This
will allow possible defective connections to the electric immersion heater to be detected immediately and
other damages resulting from this can be avoided in time!
