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 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
CAUTION
Safety devices must not be
bypassed or disabled.

Operating sequence
The units can be used in
the respective modes for air
heating and air circulation
purposes.
The units can be operated on one
heating and one fan setting. They
have a 3-stage operating switch
with the functions: Heat (I) / Off
(0) / Fan (II).
In setting I (Heat), the heating
resistor and air circulating fan are
switched on and warm air is blown
out.
The unit is equipped with an
integrated thermostat to ensure
that the room temperature is
constant.
Once the selected temperature
has been reached, the thermostat
stops the heating operation.
If the room temperature falls
below the selected temperature,
the thermostat starts up
the heating operation again.
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.
In setting II (Fan), only the air
circulating fan is switched on and
the unit can only be used for air
circulation.
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 unit operates 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. Move the operating
switch to the “I”
(Heating) position.
Fan
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 the “II” (Fan)
position.
One person, who has been
adequately trained in the handling
of the units, should be tasked with
the operation and monitoring
of the units.
The units must be in the intended
horizontal position on their
supports at all times during
operation.
1. Check that the mains power supply
matches the operating voltage
of the unit 230V/1~/50 Hz
2. Move the operating
switch to the “0”
position.
3. Connect the unit's power
plug to a properly
installed mains
socket.
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.
NOTE
For optimum operation
the units should not be
operated above an ambient
temperature of 25 °C.
CAUTION
Extensions to the connection
cable must only be conducted
by authorised specialist
electricians, taking into
consideration the unit capacity,
cable length and local use.
CAUTION
All cable extensions must only
be used in fully un-reeled
or reeled off condition.

REMKO ELT series
1. Move the operating
switch to the "0"
(Off) position.
The supply air fan runs on to cool
the units and only switches off
after the cooling down phase is
complete.
The fan can switch on and run
several times before the final
shutdown.
2. If the units are
inactive for long
periods, disconnect
them from the mains
power supply.
Shutdown TroubleshootingCare and maintenance
Regular care and observation
of some basic requirements will
ensure trouble-free operation and
a long service life of the units.
■ Observe the regular care and
maintenance intervals
■ In accordance with
the operating conditions,
the units must, if necessary,
be checked at least yearly by a
specialist to ensure that they are
in a condition that is safe to use
■ Keep the units free of dust and
other debris
■ Only clean the units with a dry
or moistened cloth
■ Never subject to direct jets of
water.
e.g. pressure washers etc.
■ Never use abrasive or solvent-
based cleaners
■ Check the inlet and outlet grille
for contamination on a regular
basis
■ Check the safety equipment and
protective devices on a regular
basis
■ Be careful not to damage
the thermostat’s probe or
capillary tube when removing
or mounting the rear panel
of the unit
The unit (fan) does not start.
1. Check the mains fuses on site.
2. Check the power plug.
3. Check the
operating switch.
4. Check that the fan can move
freely.
The unit does not heat up
1. Set the thermostat to a value
that is higher than the room
temperature.
2. Check that the thermostat is
functioning correctly.
3. Check the
operating switch.
4. Check that the contactor is
functioning correctly.
5. Check that the temperature
limiter is functioning correctly
and check it for damage.
If all of the functional checks
have been carried out without
any findings, please contact an
authorised service station.
CAUTION
Never interrupt the power
supply prior to the completion
of the follow-up cooling phase.
There is no warranty claim
for damage to the units from
overheating.
CAUTION
Before undertaking any work
on the units, the power
plug must be removed from
the mains socket.
NOTE
Repair work may only be
carried out by authorised
qualified electricians.
CAUTION
After completing any work on
the unit, an electrical inspection must
be carried out according to VDE 0701.
