Safety information
Operation of the heaters must always take place in compliance with
the local building and fire protection regulations and regulations of the
employers‘ liability insurance associations.
The units were subjected to
extensive material, functional and
quality inspections and tests prior
to delivery. However, the units
may constitute a hazard if used by
untrained personnel, improperly or
not for the intended purpose.
The following information must be
observed
■
Before starting work, persons
responsible for the operation of
the units must check for obvious
defects on control and safety
devices and for the presence
and correct functioning of
protective devices.
Any noticed defects must be
reported to the responsible
supervisor!
■
Units that have defects liable
to affect their reliability must
immediately be switched off.
■ For using the units, the
respective local regulations and
electrical fuse protection ratings
must be observed.
■
Safety distances to flammable
objects must be observed.
■ The air inlet and air outlet vents
must be kept free at all times.
■
The air outlet vents must not
be restricted or pipes or hoses
connected.
■ Never insert foreign objects into
the units.
■
The units must not be covered
whilst in operation.
■
Safety devices must not be
overridden or blocked.
■
The units must not be used near
to baths, showers, swimming
pools, etc.
■
The units must not be used
directly below a wall socketoutlet.
■
The units must not be exposed
to direct water jets.
e.g. high pressure cleaners, etc.
■
Never allow water to enter the
unit.
■
The units must not be installed
and used in locations subject to
fire and explosion hazards.
■
The units must not be installed
and used in oil, sulphur, or saltladen atmospheres.
■
All electrical cables of the units
must be protected against
damage, also damage caused by
animals.
ATTENTION
Safety devices must not be
overridden or blocked.
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 problemfree 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.

Commissioning
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.
ATTENTION
The unit must never be
disconnected from the mains
supply before the cooling
phase has ended.
Damage attributed to
overheating is not covered by
the warranty.
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.
ATTENTION
Only authorised electricians
may extend the connecting
cable taking into account the
rating of the unit, cable length
and use locally.
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.
NOTE
For optimal operation, the
units should not be operated
at ambient temperatures above
25°C.
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.
ATTENTION
All cable extensions must
be used only uncoiled or
unwound.

Decommissioning
1. Set the operating
switch to
position “0”.
The supply air fan
continues to run to cool down the
units if necessary and switches
off when an adequately low
temperature is reached.
The fan may run several times until
it switches off permanently!
2. The units must
be disconnected
from the supply
if they are not
going to be used
for extended
periods of time.
ATTENTION
The unit must never be
disconnected from the mains
supply before the cooling
phase has ended.
Damage attributed to
overheating is not covered by
the warranty.
Care and maintenance
Regular care and the observance
of a few basic conditions will
guarantee trouble-free operation
and a long service life of the units.
ATTENTION
Before carrying out all work
on the unit, the mains plug
must be disconnected from the
mains socket-outlet.
■
Observe regular care and
maintenance intervals
■
Depending on the particular
operating conditions, the
units should be tested by an
expert for reliable operation
as necessary, however at least
once a year.
■
Keep the unit free of dust and
other deposits.
■
Only clean the units dry or with
a moist cloth.
■
Do not use direct jets of water,
e.g. high pressure cleaners, etc.
■
Do not use caustic cleaning
agents or those containing
solvents.
■
Check the air inlet and air outlet
grilles for clogging.
■
Check the safety and protective
devices at regular intervals.
Troubleshooting
The unit (fan) does not start.
1. Check the local mains fuses.
2. Check the mains plug.
3. Check the operating switch.
4. Check the fan for smooth
operation.
The unit does not heat
1. Set the thermostat to a value
above room temperature.
2. Check function of the
thermostat.
3. Check the operating switch.
4. Check the function of the
contactor.
5. Check the function of the
temperature limiter and inspect
for damage.
If no result is achieved after
carrying out all functional checks,
an authorised service station
should be contacted.
ATTENTION
After completing all work
on the unit, an electrical
inspection must be carried out
according to VDE 0701.
■
Do not damage the sensor and
capillary tube of the thermostat
when removing or fitting the
rear panel of the unit.

commissioning.
The units were repeatedly tested
at the factory to ensure that they
function correctly.
Nonetheless, if the unit should
have a fault that cannot be
remedied by troubleshooting,
your specialised dealer or contract
partner should be contacted.
