Safety Instructions Make sure to observe relevant local building and fire protection codes and abide by professional association regulations when the units are in operation. The unit may only be operated by persons who have received proper training in the operation of the unit. The unit is to be installed and operated in such a way as to ensure that people are not endangered by waste gases and radiation heat and fires cannot occur. The unit may only be installed and operated in rooms, when the air-rate fed to the unit is sufficient for combustion. Units without an exhaust system may be operated only in well-ventilated rooms. Persons may not remain permanently in the room where the unit has been installed. Warning signs are to be posted at the entrances. A safety zone of 1.5 m around the unit is to be maintained even for non-flammable objects. The unit is to be installed only on a non-combustible ground. The unit may not be set up or operated in surroundings susceptible to fire or explosions. Mobile fuel containers may only be installed in compliance with technical regulations for flammable liquids. The protective air suction grille must always be kept free of dirt and loose objects. Do not insert foreign objects into the unit at any time. Do not expose the unit to a direct stream of water. All electrical cables outside the unit are to be protected from damage (e.g. caused by animals, etc.). Make sure always to pull the mains plug out of the mains socket when maintenance and repairs are carried out. While the unit is in operation, the safety mechanisms may not be bypassed or blocked! Before doing any maintenance or repair work, make sure to unplug the unit from the power supply. Never interrupt the power supply (except in emergency situations) before the unit has reached the end of the cool-down phase. Use prototype-tested WLE-type oil burners only. Description of Device The units are mobile, warm air heaters with heatexchangers and an exhaust connection for commercial use. The unit is fired directly with heating oil or diesel. It is designed for fully-automatic, universal and reliable use. The units are only operated with separate forced-air burners. The unit is equipped with a quiet, high-performance axial ventilator requiring little maintenance, a connection cable with plug and a room thermostat socket. The standard units with forced-air burners supplied directly from the factory are equipped with a fitting for an oil reservoir and an electric oil preheater. Up to CLK 70: preheater in nozzle stock. CLK 120 and higher: REMKO multifilex oil preheater. The unit complies with the basic safety and health requirements of the relevant EU regulations and is reliable and simple to operate. Areas of application The units are mobile, warm air heaters that supply instantaneous heat. They are only used for commercial purposes. The unit can be used e.g. in the following areas: for drying new buildings for point heating of outdoor workplaces for point heating of workplaces in open, non firehazard fabrication rooms and halls for heating closed and open rooms, on a permanent or temporary basis to de-ice machines, vehicles and non-flammable storage goods to maintain the temperature of components susceptible to frost as well as greenhouses Device functionality If the unit is switched to heating mode, the forced-air burner starts automatically. In fully-automatic heating mode, the forced-air burner starts only when the room thermostats determined that heat is necessary. After the burner has run for a short time, the temperature control thermostat TR (rated temperature 35 to 40 C) automatically switches the air supply fan on. Warm air is blown out. When the room thermostat is in operation, the process above is automatically repeated depending on the amount of heat required. The temperature monitor TW (rated temperature 80 to 85 C) monitors the internal temperature of the unit. After the device is switched off with the operating switch or the room thermostat, the air supply fan runs for a certain amount of time to cool the combustion chamber with heat-exchanger and then switches off. This process can be repeated several times. 4

Monitoring operation of device All functions of the unit are fully automatic and monitored for safety by the safety facility and the automatic burner relay (part of the forced-air burner). If the flame burns irregularly or goes out, the unit is switched off by the automatic burner relay. The control lamp on the control panel and the malfunction lamp of the automatic burner relay light up. Before the unit can be restarted, the automatic burner relay must be released by pressing the external reset button on the operating panel or the reset button on the automatic burner relay. The fan control (TR) regulates operation of the fan. The temperature monitor (TW) limits or regulates the temperature of the unit in heating mode. The safety temperature limiter (STB) interrupts heating mode when extreme overheating occurs or if the temperature monitor (TW) stops working or is defective. The STB can only be manually released after the unit has cooled down. Before the STB is released to begin operation again, the reason the STB was activated must be determined. While the unit is in operation, the safety features may not be bypassed or blocked! Installation in closed, well aerated rooms without connection to a chimney The units may only be operated when the minimum amount of air required for combustion is supplied. A safe exhaustion of the waste gases is to be ensured to exclude inadmissible pollution. - Fresh air is supplied from below. - Waste gases are expelled upwards. Outside installation Operation of the unit may not have any harmful effects or cause any unreasonable problems. The unit operator must ensure that unauthorised persons are prevented from manipulating the unit or its power supply. Because rain and snow can be sucked in by the air supply fan, a suitable protective covering should be used. Heating Rooms Warm air generators may only be operated with a room thermostat when heating rooms. Accessories. Make sure that there is enough fresh air to ensure optimum combustion. Installation Requirements The heaters may only be installed in compliance with the relevant regulations, in particular, regulations governing the installation and operation of fireplaces and furnaces. Any national/regional emission control laws or regulations must also be observed. Avoid under- or overpressure in the room where the unit is installed, as this would result in combustion troubles. Make absolutely sure that the opening for air intake and output is adjusted to the fan power (see model plate). If this is not possible, the burner has to be equipped with a separate air supply device to ensure optimum combustion. Electrical Connection The units are operated with 400 V / 3~N / 50 Hz. The unit must be connected to the power source at a special terminal equipped with a switch to protect against faulty currents. Extension cable may only be laid by authorised electricians based on the capacity of a unit, the length of the cable and in accordance with local requirements. All extension cable may only be used once they have been unrolled. Safety zones To ensure safe operation and guarantee unhindered access to the unit for maintenance work, a safety zone of 1.5 m should be maintained around the unit. Floors and ceilings must be fire-resistant. 5

Safety Device The device has 3 safety functions: Information on the Safety Device The device is equipped with a sensor monitoring feature and is resistant to cool down to temperatures of -20 C; below -20 C the device switches off; when the temperature rises above this temperature, it switches on again. When the sensor or capillary tube is damaged, or when an excess temperature of approximately 220 C is reached, the liquid contained in the thermostat is emptied and the device switches off for safety purposes. The device is no longer operable and must be replaced If it is necessary to replace the STB, only the original REMKO part may be used. Fan control (TR) Temperature monitor (TW) Safety temperature limiter (STB) Fan control (TR) The fan control switches the circulating air fan off and on. The point at which the device is switched on or off is set in the control box via the temperature control thermostat Scale 21 60. Rated value approx. 35 to 40 C. Temperature Monitor (TW) When the unit is in heating mode, the temperature monitor limits both the temperature of the unit and the air being blown out. The switching point is set via the temperature control thermostat Scale 34 110 in the control box. Rated value approx. 80 to 85 C. Safety Temperature Limiter (STB) The STB controls the temperature monitor. The switching point is fixed. The burner is prevented from being restarted if the STB is activated. After the cover next to the control panel is removed, the reset button must be pressed from the outside. After the STB has been reset, the cover must be replaced. Before a STB reset, check the operating conditions to ensure that the STB temperature is not exceeded again. Make sure to install and mounting the device carefully. Do not bend the capillary tubes near to solder points. When installing the capillary tubes, be careful not to damage or bend them too sharply. The sensors may only be mounted in the mounting brackets supplied by the manufacturer. The sensors must always be free from dust and dirt. Waste Gas Pipes When the units are operated outside or in open rooms you do not need a waste gas pipe. However, we recommend using a waste gas pipe 1 m long (see example 2) with a rain cover on top to prevent the penetration of rainwater and dirt. If the units are used as room heaters, it is necessary to route the waste gases to the outside. Make absolutely sure that counter pressure is not created by improperly laid waste gas pipes. The unit generally operates properly when the waste gas pipes have been laid at an incline and assembled with vertical end pipes. The waste gas pipes must reach at least beyond the gutters but preferably above the top of the roof to prevent counter pressure caused by weather conditions (e.g. wind). All waste gas pipe components must be securely fastened. They may not be smaller in diameter than the waste gas connection. A minimum distance of 0.6 m must be maintained from flammable objects. Waste gas components incl. fasteners can be purchased as accessories. When using an waste gas connection, the burner must be adjusted accordingly. Example 1 Example 2 Example 3 Operation with exhaust gas pipe extended. Requires condensation trap max.1 m. Operation without exhaust gas pipe extended. max. 1 meter Inadmissible installation. Important Information. To prevent damage to the combustion chamber caused by moisture build-up (condensation) (see example 3), make sure that the waste gas pipes have a properly installed condensation trap (see example 1). more than 1 m. 6

Before Starting Prior to initial operation, check the unit for any visual defects on the control and safety devices, that the unit has been installed correctly and that it has been properly connected to the mains. Observe the following points: Install the unit in a stable position. Make sure that air is supplied for combustion. Make sure that the air can be sucked in and be exhausted freely. Avoid overpressure and underpressure in the room where the unit has been installed. Make sure that enough fuel is supplied. Please note: the multifilex oil preheater will only function properly if voltage is supplied to the unit for a longer time prior to initial operation. Use only clean heating oil or diesel. Do not use bio diesel. Flexible fuel tubes must be protected from being damaged, e.g. from forklifts, animals, etc. Paraffin accumulation at low outside temperatures A sufficient amount of heating oil must be able to flow freely even when temperatures are low. Paraffin can accumulate even at temperatures below 5 C. Appropriate measures must be taken to prevent this. Use winterised heating oil or winter diesel. Connection to the power supply The units are operated with 400 V / 3~N / 50 Hz. The unit is connected to the power supply by an attached power cable with a grounded contact plug. The unit must be connected to the power supply at a special terminal equipped with a switch to protect against faulty currents. Extension cables may only be laid by authorised electricians based on the capacity of a unit, the length of the cable and in accordance with the intended use. Extension cables may only be used once they are unrolled. Additional information The waste gas values of the oil-burner are to be checked and properly adjusted by authorised personnel to ensure compliance with local requirements. Starting Only those persons who have been trained in operation of the unit may be responsible for operating and monitoring it. Important information about starting the cold unit The preheating of the nozzle stock delays the temperature depending start of the CLK 30 to CLK 70 units delivered with forced-air burners.

When heat is required, the forcedair burner switches on automatically; operation of the unit is fullyautomatic. Hot air distribution The units are equipped with a high-performance axial fan. This fan has been designed to transport the hot air directly and effectively. It is preferable to distribute air by means of pipes or special hot air hoses. Warm air may only be distributed in accordance with the fan capacity of the unit in operation. Please follow these instructions when attaching warm air hoses: Use only warm air hoses (accessories) approved by our company. Make sure that the hoses and/or pipes are securely attached to the unit s air outlet connection. To prevent heat from building up, the pipes and hoses may not have sharp kinks and bends. Counter pressure may not be allowed to build up when using hoses to heat closed rooms. If suction temperatures increase or if there is resistance on the air output opening, the forced-air burner can be switched off at short notice by the temperature monitor (TW) in heating mode. When the temperature falls, the burner restarts automatically. If the intervals are too short, the length of the warm air hoses should be checked. Avoid starting the burner in frequent cycles (under 5 min.). When the temperature is too high on the unit s outgoing air side, the heating-operation is interrupted automatically by the STB! Unit Shut Down 1. Set the operating switch to 0 OFF. 2. Shut off the fuel supply. Important information about the unit s cool-down phase The air supply fan continues running to cool down the combustion chamber and then stops at a later time. The fan can run several times before the unit is finally switched off. Never interrupt (except in emergency situations) the power supply until the cool-down phase is completely finished. Our guarantee does not cover damages caused to the unit by overheating.

Initial Operation of the Forced Air Burner Preparation After loosening the 4 housing bolts, remove the mounting base plate of the housing so that it is suspended to the side. There are 6 housing bolts to disassemble for the SL 44 model (look for the arrows). The operating parts are immediately accessible and can now be serviced. Setting ignition electrode and device A D C B size \ dimension A B C D SLV 11 und 33 2-4 4-6 7 2,5 SL 44 13-15 12-14 5 3 All measurements are approx. values in mm. The optimum setting must be adjusted to local and structural requirements. To service, insert or replace the nozzle, the base plate must be suspended horizontally by hooks. Proceed as follows: 1. Hold base plate horizontally. 2. Push right-hand mounting laterally into hook device. 3. Hook left-hand side into the lug. Air slide plate The adjustable air slide plate is used to adjust the burner pressure to the amount of resistance in the combustion chamber and the chimney draught without having to make changes to the original cross-section. 1. Loosen socket screw. 2. Turn air slide plate to desired setting. Pay attention to the arrows. Turn to min Turn to max =reduced burner pressure =increased burner pressure Required nozzle sizes Selecting the required oil nozzle depends on the pump pressure and the unit capacity. You may only use an oil nozzle that is suitable for the shape of the respective burner chamber with a corresponding spray angle, cone properties and throughput. You can find the required oil nozzle sizes under Technical Data. Base plate After changing the nozzle and setting the air slide plate, reassemble the base plate in the reverse order. 16

Secondary air setting (Setting the nozzle stock) 1 2 Adjusting the air flap Proceed as follows to adjust the air flap: 1. Loosen the knurled nut 4. 2. Rotate the adjustment screw 3 accordingly. 3. Keep the following in mind: Right rotation = less air Left rotation = more air 4. After the adjustment is completed, retighten the adjustment screw with the knurled nut. Proceed as follows to preset the secondary air: Use the adjusting screw 1 to adjust the nozzle 2 to the value you want. SLV 11 und SLV 33 SL 44 Air flap Counter clockwise (-) = lower scale values increased pressure behind the air flow plate lower performance range Clockwise (+) = higher scale values lower pressure behind the air flow plate upper performance range. Counter clockwise (+) = higher scale values reduced pressure behind the air flow plate upper performance range Counter clockwise (-) = lower scale values increased pressure behind the air flow plate lower performance range. The adjustment screw 3 is used to set the required quantity of air. The air flap is opened or closed until the soot profile displays an oil-free colour 0-1. Additional Information If the air flap is completely open and the flame emits smoke or flickers, use the secondary air setting to lower the pressure behind the air flow plate. It might be necessary to open the air slide plate even further. Setting the pump pressure For initial burner operation and after each time the burner is serviced, the oil pressure must be adjusted and/or checked. Never operate the pump without fuel! Proceed as follows to adjust the pump pressure 1. Remove the stopper on the P measuring connection. 2. Mount the oil manometer. 3. Open all shut-off fittings in the oil supply. 4. Switch the burner on. 5. Set the required oil pressure in accordance with the size of the nozzle and the unit performance. 6. Switch the burner off. 7. Disassemble the oil manometer. 8. Replace the stopper and its seal. 3 4 Important Information The forced-air burner may only be put into operation by trained personnel. All specifications only serve as presets and must be set or adjusted after the waste gas has been analysed. Exhaust emissions must be restricted in accordance with the ordinance on small furnace systems. 17
