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 blow off must be ensured. ◊ 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).

Connecting cable extensions may be laid exclusively by authorized electricians based on the unit capacity, cable length and taking the local terms of

G

use into account.

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.

Working of device

The units are equipped with a 4-stage operating switch. In the first stage only the supply air fan is operated and

the units can be used for air circulation. In the 2nd – 4th. stage the heating elements are acti-

vated and hot air is discharged. 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 continues running for a certain time to cool down the heat exchanger, and then it stops automatically.

Starting

A well trained person is to be charged with the operation and control of the units.

The electric connection of the units is to be carried out via a special supply point with fault current

G

safety switch.

Description of Device

The units are operating with electric energy. They are specially designed for the usage of hot air hoses and 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.

1. Check the main voltage is in accordance with the unit voltage.

Electrical connection 400 V 3 / N ~ Frequency 50 Hz Fuse protection (required) 32 A (inert)

2. Put operating switch into position "0".

3. Connect the unit-plug to an adequate mains socket.

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 position “1”.

Heating without room thermostat

The unit runs under continuous duty.

1. Plug the supplied bridge circuit plug 2 into the thermostat socket 1 of the unit.

2. Put operating switch into desired position (2 or 3 or 4) depending on the desired heating capacity.

For optimum unit operation, the device should not be operated at an ambient temperature above 25 °C.

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.

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.

Maintenance and Service

Regular maintenance and the observation of some basic principles is important to ensure a long service life and a trouble-free operation of the unit.

Prior to starting any work make sure to pull the mains plug out of the mains socket!

G

Heating with room thermostat

The unit runs fully automatically and is dependent on set temperatures.

1. Remove the bridge circuit plug 2.

2. Plug thermostat plug 3 of the room thermostat (accessories) into the thermostat socket 1.

3. Put room thermostat 4 in a suitable

place.

The thermostat sensor may not be exposed directly to the hot air current and not fixed directly on a cold surface.

4. Pre-select desired room temperature on the room thermostat.

5. Put operating switch into desired position (2 or 3 or 4) depending on the desired heating capacity.

If the temperature at the blower aperture rises above 100° C the heating operation is stopped.

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 installed 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.

Please carry out an electrical safety test after having finished service on the unit.

Hot air distribution

The unit is equipped with a high efficiency axial fan. The high efficiency axial fan permits operation with hot

air hoses in different variants to transport the warmed air exactly and efficiently to the specific place.

Please observe the following instructions when hot air hoses are to be fitted:

◊ Please use exclusively those hot air hoses (acces-

sories) which have been approved by our company.

◊ The internal overlapping at the seams must to point

at air direction.

◊ Make sure that the hot air hoses are safely fastened

to the outgoing air connection piece.

◊ The pipes and hoses may not have sharp kinks and

bends in order to avoid heat accumulation.

◊ If the temperature at the blower aperture rises above

100° C the heating operation is stopped.

◊ A free air blow off must be ensured.

Due to the special high efficiency axial fan, the unit should not be operated without hot air hoses.

Troubleshooting

Prior to starting any work make sure to pull the mains plug out of the mains socket!

Setting and maintenance is to be carried out

G

only by authorised experts!

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 contactor

3. Check function of temperature limiter resp. check capillary tubing (if damaged)
