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 ratings must be
taken into account.

■

Safety distances to flammable

objects must be maintained.

■ 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 in the
respective modes for air heating
and air circulation.

The units are operated on one heat
and one fan setting. They have a
three-position operating switch
with the functions:
Heat (I)/Off (0)/Fan (II).
In the setting I (Heat), the heating
resistor and air circulating fan are
switched on and warm air is blown
out.

In order to ensure a constant
room temperature, the unit has an
integrated room thermostat.
The thermostat switches off
the heater when the selected
temperature is reached and
switches it on again when the
temperature falls below the
selected 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.

In the 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 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.

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 230V/1~/50 Hz.

2. Set the operating
switch to position
“0“.

3. Plug the unit into
a properly installed
mains socket-outlet.

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.

ATTENTION

All cable extensions must
be used only uncoiled or
unwound.

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 position “I” Heat.

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 “II” Fan.

REMKO ELT 2-1

Decommissioning TroubleshootingCare and maintenance

1. Set the operating
switch to position
“0“ (Off).

The supply air fan continues to run
to cool down the unit 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.

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.

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.

■

Check the safety and protective

devices at regular intervals.

■

Do not damage the sensor and

capillary tube of the thermostat
when removing or fitting the
rear panel of the unit.

ATTENTION

After completing all work
on the unit, an electrical
inspection must be carried out
according to VDE 0701.
