REMKO ELT 10-HT
Safety notesUnit description
The units are portable electric
heating units for industrial
applications at various locations.
The units are operated exclusively
with electric power and have been
designed for high-temperature
applications with an air outlet
temperature of up to 120°C.
The air outlet temperature is
altered by manually adjusting the
fan speed.
The units can be operated using no
more than one high-temperature
hose (accessory) with a ø of
205 mm and a length of 7.6 m.
The units are equipped with
special-purpose, highly efficient
electrical heating coils for
immediate and consistent heat
generation, low-maintenance axial
fans, a safety thermostat, a room
thermostat socket and a mains
cable with earthed safety 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 heat-resistant materials
■
Generating process heat for
industrial applications
■
Hardening plastics
■
Pest control
■
Drying out construction work/
heating
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:
■ In the event of defects that
endanger the operational safety
of the unit, operation must be
discontinued immediately
■ Observe the respective local
electrical regulations and the
necessary safety measures when
using the units
■ Maintain safety distances to
combustible materials
0.5 m at the side of the unit and
on the air inlet side
2.0 m on the air outlet side
■ An unobstructed air inlet and air
outlet must be guaranteed at all
times
■ The units must not be covered
during operation
■ Never insert foreign objects into
the units
■ The units must not be operated
in the vicinity of bathtubs,
showers, swimming pools etc.
■ The units must not be operated
directly below a wall socket
■ The units may not be exposed to
direct jets of water
■
The units must not be installed or
operated in potentially flammable
or explosive environments
■
The units must not be operated
in locations where:
Combustible gaseous, air or
dust-air mixtures could be
produced; flammable small parts
could be sucked in, set alight on
the heating coil and blown out
in a glowing state
■
Flooring and ceilings must be
fire retardant
■
The air inlet and outlet must not
be constricted
■
The relevant safety guidelines
of the Employer's Liability
Insurance Association or
property insurer must be
observed
■
The units must be installed
in a stable position and must
not topple over or slide out of
position during operation
■
The units must not be left
unattended during operation
■
The units must not be operated
in an environment with an
ambient temperature of over
60°C
■ All electrical cables for the
units must be protected against
damage, even damage caused
by animals
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.

Commissioning
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 are equipped with
a 3-stage operating switch.
1. Move the operating
switch to the “0”
position.
2. Connect the unit's
power plug to a
properly installed
16 A 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.
Heating without room
thermostat
The units are operating in
permanent operating mode.
1. Connect the supplied strapping
plug [2] to the thermostat
socket [1] on the unit.

2
Heating with a special
purpose HT room thermostat
or duct thermostat (accessories)
The units operate fully
automatically and according to the
air outlet/room temperature.
1. Pull out the strapping plug [2].
2. Connect the plug [3] of the
relevant thermostat to the
thermostat socket [1] on the
unit.

3
3. Place the probe in a suitable
position according to the type
of thermostat used.
The thermostat probe must not
be located directly in the warm
air flow and must not be placed
directly on the cold floor.
4. On the room thermostat, set
the temperature required for
the application at hand.
5. Move the operating
switch to the “2”
(Heating) position.

approx. 5 minutes, please decrease
the fan speed by approx. 10%.
If the

the previous procedure until the
YELLOW HT operating light
continuously lit.
The unit has now been optimally
adapted to the ambient conditions
and is operating in hightemperature mode at approx.
100-120°C.
Safety in the event of
excessive temperature
If the operating conditions change in
permanent operating mode and the
temperature at the air outlet exceeds
120°C, the unit reverts to a heating
capacity of 7 kW automatically.

In the event of serious heat build-up
caused by, for example, a constricted
air outlet, a lack of unrestricted air
intake or the fan being at a standstill,
the safety thermostat switches the
unit off. This needs to be manually
unlocked once the fault has been
rectified and the unit has cooled down.

Ventilation only operation
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 the “1”
position.
The fan speed can
likewise be changed
in this mode.
Operation with
a warm air hose
The units are equipped
with a special-purpose high
performance axial fan.
This opens up the possibility of
operating the unit with an HT warm
air hose with a Ø of 205 mm and
a length of 7.6 m to transport the
heated air efficiently and effectively
to the place where it is required.
Care and maintenance
Regular care and observation
of some basic requirements will
ensure trouble-free operation and
a long service life of the units.
!
CAUTION
Before undertaking any work
on the units, the power plug
must be removed from the
mains socket.
■
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
Shutdown
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.
3. The supply air fan may run
on to cool the units and only
switch off after the cooling
down phase is complete.
4. If the units need to be stored,
clean them and, if necessary,
cover them with a plastic sheet/
film or cotton cloth and store
in a sheltered and dry storage
location.
Only warm air hoses (accessories)
that have been approved by
Remko may be used as these have
been designed specifically for these
high temperature units.
Note about the assembly of the
warm air hose
■
Only special-purpose high-
temperature hoses may be used
■
Make sure that the unit’s outlet
nozzle is securely fastened
■
There should be no kinks or
bends in the hose lines in order
to prevent hot-spots forming
■
Make sure that the air outlet at
the end of the hose is clear at
all times
■
Never subject to direct jets of
water.
e.g. pressure washers etc.
■
Never use abrasive or solvent-
based cleaners
■
Use only suitable cleaners, even
for heavy contamination
■
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 temperature controllers’
probes or capillary tubes when
removing or mounting the
protective exhaust grid
!
CAUTION
An electrical safety check must
be carried out in accordance
with VDE 0701 after any work
on the units.
