Unit description
The units are portable electric
heating units for industrial
applications.
The units are operated exclusively
with electric power and have been
designed in such a way that they
can be used fully automatically,
universally and in a straightforward
manner.
The units are equipped with
specially enclosed electric heating
resistors, low noise and low-
maintenance axial fans, a safety
and aftercooler thermostat,
an integrated room thermostat
and a power supply cable.
The units conform to
the fundamental health and safety
requirements of the appropriate
EU regulations.
The units are dependable and offer
ease of operation.
The units may be used among
other things for the following:
■ Drying newly completed
buildings
■ Spot heating outdoor
workspaces or fire-proof
manufacturing facilities and
halls
■ Continuous or temporary room
heating
■ De-icing machines, vehicles and
non-combustible warehoused
goods while adhering to
the relevant safety distances
CAUTION
Safety devices must not
be bypassed or disabled.

5
Operating sequence
The units can be used according
to the relevant operating modes
for air heating or simply for air
circulation purposes (switch
position 1).
The heating capacity can be set in
2 stages (switch position 2 and 3).
The units are equipped with an
integrated thermostat to ensure
that the room temperature
is constant.
Once the set temperature has
been reached, the thermostat
switches the heating operation
off. If the room temperature
falls below the set temperature,
the thermostat starts up the
heating operation again.
The integrated thermal cut-
out switches off the unit if
the temperature is excessively
high and switches it on again
automatically after it has cooled
down.
After switching off the units via
the operating switch or the room
thermostats, the supply air fan
runs to cool the heating resistors
for a certain time and then
switches off automatically.
Commissioning
Heating
The units operate in a fully
automatic manner subject
to the temperature that is set
on the thermostat.
1. Set the desired
room temperature
on the thermostat.
2. Depending on the desired
heating capacity,
move the operating
switch to position
“2” = 4.5 kW
or “3” = 9 kW.
Ventilate
Only the supply air fan operates
in this setting. Thermostatic
regulation and heating operation
are not possible in this operating
mode.
1. Move the
operating switch
to position “1”,
ventilate.
One person, who has been
adequately trained in the handling
of the units, should be tasked with
the operation and monitoring
of the units.
1. Check that the mains power
supply matches the operating
voltage of the unit.
400V/3~N/50 Hz.
2. Move
the operating
switch to
the "0" (Off)
position.
3. Connect
the unit's
power plug
to a correctly
installed mains
socket.
400V/3~N/50Hz
NOTE
The electrical connection for
the units must be made at a
separate feed point with a residual
current device in accordance with
VDE 0100, Section 55.
