Unit heaters with 2-stage three-phase motor / Unit heaters with 1-stage single-phase motor
Installation and operating instructions
Important:
Note the maximum flow temperature to protect the fan!
Long periods of fan idleness with high water temperatures can lead to
impermissible heating of the fan motor. The flow temperatures should
therefore be limited depending on the use and motor configuration.
Should a temperature limit not be possible or not be sensible for
the intended use, there is also an option of using appropriate valves
(thermoelectric, motorised or solenoid) to shut off the heating medium.
This can interrupt the flow of medium before the fan is switched off
and the heat exchanger cools down. Appropriate fan controllers with
a fan run-on relay and connection terminals for the motorised valve are
available on request.

2.3 Safety information
Installation, assembly and maintenance work on electrical units may
only be performed by a qualified electrician (in compliance with VDE
regulations). The connection should comply with the VDE regulations
and provisions laid down by the regional electricity providers.
Non-compliance with the regulations and operating instructions can
result in the units malfunctioning with consequential damage and
danger to people. There is a danger of fatal injury caused by wires being
crossed due to incorrect wiring!
Regularly check the unit heater's electrical equipment. Immediately
replace loose connections and faulty cables.
Disconnect all parts of the system from the mains power supply and
prevent them from being reconnected before starting any connection
and maintenance work!
