Safety Instructions

REMKO electric heaters will provide you with high utility

and long life thanks to our extensive material, function

and quality controls. Dangers may arise nevertheless if

the unit is used by persons not familiar with its operation

or if the unit is not used for its intended purpose.

◊The persons charged with the operation of the units

have to check these before starting work as to visible

defects of the operation and safety devices, as well as

to make sure that no protective devices are missing.

In the case of faults the supervisor is to be informed.

◊In the case of faults which endanger the safe opera-

tion of the units, the units are to be stopped!

◊During the operation of the units the applicable local

regulations are to be observed and the relevant

safety measures to be taken.

◊Make sure that the prescribed safety distances from

combustible objects are observed!

◊A free air suction and air discharge must be ensured.

◊The blow off opening of the unit may not be narrowed

or equipped with hoses or conduits.

◊Never place foreign objects into the unit.

◊Do not cover the units during operation.

◊The units may not be operated near bath tubs, show-

ers, swimming pools, etc.

◊The units may not be operated directly beneath a wall

socket.

◊The units may not be exposed to direct water jets.

◊Make sure that no water penetrates inside the units.

◊The units may not be operated in rooms which are

endangered by explosions.

◊Protect all electric cables outside the units from

damage (e.g. caused by animals). Starting

A well trained person is to be charged with the operation

and control of the units.

1. Check the main voltage is in accordance with the

unit voltage.

Description of Device

The units are operating with electric energy and are suitable

for a fully automatic, all-purpose and simple application.

The units are equipped with capsuled electrical heating

elements, noiseless maintenance-free axial fans, safety

and after-cooling thermostat, thermostat socket and

connecting cable with plug.

The units are in accordance with the basic safety and

health requirements of the relevant EC –regulation.

The units are handled simply and are safe in operation.

Application

◊Drying of new buildings, spot heating of working places

outside or in fire-proof halls and production places.

◊Permanent or temporary heating of rooms.

◊Defrosting of machines vehicles and fire-proof storing

goods with keeping the prescribed distance of safety.

Connecting cable extensions may be laid exclu-

sively by authorised electricians based on the

unit capacity, cable length and taking the local

Working of device

All units can be used for heating or ventilation by setting the

equivalent mode on the operating switch.

The unit ELT 3-2has got exclusively on heating stage and

has a 2 step operating switch.

The units ELT 10-6and ELT 18-9has got three heating

stages.

The units can be operated with a room thermostat

(accessories) which is ready to be plugged in, to ensure

a constant room temperature. When the pre-selected

temperature has been reached, the thermostat stops

the heating operation to restart it when the temperature

has fallen below the set value.

When the units have been switched off by the operating

switch or the room thermostat, the supply air fan contin-

ues running for a certain time to cool down the heat ex-

changer, and then it stops automatically.

ELT 3-2ELT 10-6

ELT 18-9

The electric connection of the units is to be carried

out via a special supply point with fault current

safety switch.

Ventilation

In this position only the supply air fan runs. The thermo-

static regulation and the heating operation is not possible.

1. Put the operating switch into the necessary position.

Maintenance

Regular maintenance and the observation of some ba-

sic principles is important to ensure a long service life

and a trouble-free operation of the unit.

Attention, important hints to the after-cooling phase.

The air supply fan continues running to cool down the

unit and then stops later.

Fan can start several times before final switching off.

Unit Shut Down

Switch settings

1. Connect the supplied bridge

circuit plug 2to the thermostat

socket 1of the unit.

2. Put the operating switch into the

desired position.

Heating without room thermostat

The unit runs under continuous duty.

1.Remove the bridge circuit plug 2.

2. Connect thermostat plug 3of the

room thermostat (accessories) to

the thermostat socket 1.

3. Put room thermostat 4in a suitable

place.

The thermostat sensor may not be

exposed directly to the hot air cur-

rent and not fixed directly on a cold

surface.

4. Pre-select desired room tempera-

ture on the room thermostat.

5. Put the operating switch into the de-

sired position.

Heating with room thermostat

The unit runs fully automatically and is dependent on set

temperatures.

Please pay attention to the following points:

◊The unit is to be maintained and cleaned in regular

intervals.

◊The unit is to be kept free from dust and other de-

posits and is to be cleaned only with a dry or humid

cloth.

Do not use water jet.

◊Do not use any aggressive cleaning agents or those

which are harmful or environmentally unfriendly.

◊Do not use cleaning agents which contain solvents.

◊Only use suitable cleaning agents to remove ex-

treme dirt.

◊Check safety devices regularly.

Check protective suction and blower grids regularly

and clean, when necessary.

◊Do not damage the sensor and capillary tube of the

thermostat when the protective blower grid is in-

stalled or removed.

◊According to the terms of use the units are to be

checked as to their perfect operation by an expert

when necessary, but at least once a year.

Never interrupt (except in emergency situations)

the connection to the mains before the end of the

whole after-cooling phase.

Our guarantee does not cover damages caused

to the unit by overheating.

Prior to starting any work make sure to pull the

mains plug out of the mains socket!

Please carry out an electrical safety test after hav-

ing finished service on the unit.

Troubleshooting

Unit (fan) does not start:

1. Check main fuse

2. Check connecting cable with plug

3. Check operating switch

4. Check slight drifting of fan (motor)

Unit does not heat

1. Check operating switch

2. Check auxiliary relay / contactor (ELT 10-6 / ELT 18-9).

3. Check function of temperature limiter resp. check

capillary tubing (if damaged)

4. Check if thermostat plug resp. bridge circuit plug is

coupled

5. Check thermostat-operation: thermostat must be set

higher than the room temperature
