Unit description
The units are portable electric
heaters for commercial use.
The units are designed solely
for electrical use and for fully
automatic, universal and problem-
free operation.
The units have special
encapsulated electric heating
resistors, a low noise and
maintenance axial flow fan, a
safety and cooling thermostat, an
integrated room thermostat and
power cable with earthing pin
plug.
The units comply with the
fundamental safety and health
requirements of the pertinent EU
directives.
The units are reliable and easy to
operate.
The units also have the following
applications:
■ Drying new buildings.
■ Concentrated heating of
outdoor workplaces or for use
in halls and manufacturing
facilities not subject to fire
hazards.
■ Continuous or temporary room
heating.
■ De-icing of machines, vehicles
and non-flammable stored
goods, maintaining the
appropriate safety distances.
ATTENTION
Safety devices must not be
overridden or blocked.

Operation
The units can be used for air
heating or only air circulation
depending on the respective mode
selected (switch position 1).
The units have two heat settings
(switch positions 2 and 3).
In order to ensure a constant room
temperature, the units have an
integrated room thermostat.
The thermostat switches off the
heater when the set temperature
is reached and switches it on again
when the temperature falls below
the set value.
The integrated temperature
limiter 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 unit at
the operating switch or room
thermostat, the air supply fan
continues to run for a certain
period of time to cool the heating
resistors
and switches off automatically.
Commissioning
Heat
The unit operates fully
automatically depending on the
temperature set at the thermostat.
1. Setting the required
room temperature
at the thermostat
2. Set the operating
switch to the
required heat
output - position
“2” = 4.5 kW or
“3” = 9 kW.
Fan
In this position, only the supply air
fan runs. Thermostatic control and
heating are not possible.
1. Set the operating
switch to position
“1” Fan.
Operation and monitoring of the
units must be carried out by one
person who has been adequately
instructed in the use of the unit.
1. Check the system voltage for
correspondence with the unit
voltage 400V/3~N/50 Hz.
2. Set the operating
switch to position
“0” (Off).
3. Plug the unit
into a properly
installed mains
socket-outlet.
400V/3~N/50Hz
NOTE
Electrical connection of the
units must be made at a
separate supply point using
a residual-current-operated
circuit-breaker according to
VDE 0100 § 55.
NOTE
For optimal operation, the
units should not be operated
at ambient temperatures above
25°C.
