The units are portable electric
heating units for industrial
applications.
The units are operated exclusively
with electric power and have been
designed specially for use with hot
air hoses.
The units are equipped with
specially enclosed electric heating
resistors, low noise and low-
maintenance axial fans, safety and
aftercooler thermostats, a room
thermostat socket and power cable
with protective contact plug.
The units conform to the
fundamental health and safety
requirements of the appropriate
EU stipulations.
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
Safety notes Unit description
The units have been subjected
to extensive material, functional
and quality inspections prior to
delivery. However, dangers can
arise from the units if they are used
improperly or not as intended by
untrained personnel!
Please observe the following notes:

and protective devices on
a regular basis
■ Be careful not to damage the
probe or capillary tube of the
temperature limiter when
removing or mounting the
protective exhaust grid
1. Move the operating
switch to the “0”
position.
2. If the units are inactive for long
periods, disconnect them from
the mains power supply.

after the cooling down phase is
complete.
The fan can switch on and run
several times before the final
shutdown.

Care and maintenance
Fan
Only the supply air fan operates
in this setting. Thermostatic
regulation and heating operation
are not possible in this operating
mode.
Move the operating
switch to position 1.
Heating with room thermostat
(accessory)
The units operate fully
automatically and according
to the room temperature.
1. Pull out the strapping plug 2.
2. Connect the plug 3 of the
room thermostat 4 with the
thermostat socket 1 on the unit.
3. Place the room thermostat 4 at
a suitable location in the room.
The thermostat sensor must not
be located directly in the warm
air flow and must not be placed
directly on a cold floor.

by authorised specialist electri-
cians, taking into consideration
the unit capacity, cable length
and local use.
CAUTION
Before undertaking any work
on the units, the power plug
must be removed from the
mains socket.
CAUTION
Never interrupt the power
supply prior to the completion
of the follow-up cooling
phase. There is no guarantee

Operation with hot air hoses
The units are equipped with a
special high performance axial fan.
This enables operation with various
types of hot air hoses, in order
to specifically and effectively
transport the heated air to the
respective application location.
Only use hot air hoses (accessories)
approved by us, because these
have been specially tailored to the
units.
Note for installing the hot air
hoses
■ The inner overlapping on
the seams must point in the
direction of the air flow.
■ It is necessary to ensure secure
fastening to the unit outlet
nozzle or the hose extension.
■ There should be no sharp kinks
or bends in the hose lines in
order to prevent hot-spots
forming.
■ Always ensure an unobstructed
air outlet at the end of the
hose.

operation without a hose
connection (clear blow-out)
should be avoided.

with a room thermostat, set
the thermostat to a value
that is higher than the room
temperature.
If all of the functional checks
have been carried out without
any findings, please contact an
authorised service station.
