5. Electrical installation
This chapter describes how the heateris connected to a sauna control unit or power switching
device.
5.1 General instructions for electrical installation
Ensure that electrical installation is performed in compliance with the standards and legal norms
valid in your country.
Observe the following regulations when installing sauna heaters: IEC 60364-7-703 and/or DIN VDE
0100 part 703:
This most recent version of the standard under amendment of paragraph 703.412.05, states the
following: "The additional protection must be provided for all of the sauna's electric circuits by one
or more residual current devices (RCDs) with a rated differential current no greater than 30 mA,
with the exception of sauna heaters. "
If a residual current device (RCD) is installed, ensure that there are no other electrical consumers
not belonging to the sauna system which are fused via this RCD.
If the sauna heater has not been used for an extended period of time, the heater may draw
moisture from the ambient air, which, in rare cases, could lead to the RCD to be tripped. This is a
physical process and not a fault on the part of the manufacturer.
In this case, the heater must be heated by a technician under supervision which will bypass the
RCD function. Once the moisture has escaped from the heating elements after approx. 10 minutes,
the RCD can be integrated again in the electric circuit.
If the sauna heater will not be used for an extended period of time, we recommend that you switch
on the heater every 6 weeks so that the heating elements do not accumulate moisture. If, during
commissioning, the RCD is triggered, the electrical installation must be checked again.
The electrician is responsible for properly connecting the heater; thus, the manufacturer does not
assume liability.
5.2 Heating time limitation
Heating time limitation functions
►
All sauna heaters, except for those installed in public saunas, and which are operated under the
supervision of personnel, must be equipped with a timer that complies with IEC and EN standards.
This timer fully disconnects the sauna heater from the power supply for safety reasons. It is typi-
cally integrated in the sauna control units. The timer must be mounted outside of the sauna cabin
and may not be overridden.
The operation time of a public sauna must be limited so that the heating elements are
ƒ
without power for a minimum of 6 consecutive hours within a 24-hour period.
Units used in private saunas must be limited to an operating time of 6 hours, and an auto-
ƒ
matic restart is not permitted.
