Initial Operation
Prior to initial operation
Prior to initial operation, the following must be com-
pleted:
1. Check that assembly is mechanically sound.
2. Check that the connection to the customer-installed
heating system is correct.
3. Check that the frost protection mechanism is work-
ing properly
If assembled.
4. Make sure that hot surfaces, e.g. the supply lines,
are protected against unintentional contact.
5. Ensure that the unit’s electrical wiring has been
made in accordance with the relevant guidelines and
standards and complies with the enclosed wiring
diagrams.
6. Check the fan area as well as the air intake and out-
let area for foreign objects.
7. Make sure that all air outlet openings are opened.
8. Ensure that the distance between the fan wheel and
housing is the same all the way around.
9. Activate the power supply to the switching unit and
switch the unit on via the control switch.
10. Check to make sure that the fan is rotating in the di-
rection of the arrow.
The rotational direction can be changed by reversing
the 2 phases.
11. Remember that when using speed control, the ca-
pacity of the regulating unit must be adjusted to the
capacity of the motor.
12. Initial operation is prohibited until it is ensured that
the proper assembly and electrical installation corre-
sponds to the provisions of the EU guidelines
89/392/EWG and 73/23/EWG.
During initial operation
All regulating, control and safety mechanisms must be
checked to ensure that they are functioning properly
and set correctly during initial operation.
1. Measure the power consumption of the fan.
The rated current may not exceed the value speci-
fied on the type plate in each switch phase.
2. Check the control/regulating function of the fan.
3. Check the motor protection function of the fan.
4. Check the function of the frost protection mecha-
nism and the room thermostat
If mounted.
5. Check that the fan is running quietly.
6. Check the entire system for any vibrations.
7. Check that the heating medium supply lines have
been properly connected and are impermeable.
The control switch must always be reset to “0” to
restart the unit after the switching unit is sepa-
rated from the power supply, following a power
outage or a malfunction.
Shutting Down the Unit
Prior to longer periods of non-operation
◊ Switch all poles of the electrical connections off.
◊ If there is a danger of frost, drain the system if the
heating medium (water) has not been mixed with a
suitable anti-freeze.
It is only possible to completely drain the heat-
exchanger with compressed air.

mercial heating and insulation purposes on the basis of
their design and equipment.
The manufacturer assumes no liability for damage re-
sulting from non-compliance with manufacturer specifi-
