SPECIFICATION

CONTENTS

ASSEMBLY

Remove the heater from the carton.
If the unit is damaged in any way DO NOT use and contact the Supplier.

ASSEMBLY (fig.1)
To assemble the heater, proceed as follows (see Fig. 1):

• Insert the axle J to the corresponding hole of frame E and insert the split pins K to the corresponding holes.
• Slide plain washer I onto the axle up to the sides of the frame.
• Slide the wheel H over the axle J and screw the nut G onto the end of the axle to fix the wheel in place ensuring that it can rotate freely and securely.
• Put the heater body on the frame assembly, and make sure the 4 holes of handle A point towards the corresponding 4 holes on the frame respectively.
• Use screw B, spring washer C, plain washer D, and nut F to securely fix the frame to the tank.

INSTALLATION

Position the heater on a flat, level, non-flammable, solid surface. The exhaust gases are very harmful for people and animals when released in a closed space without ventilation. Indirect-fired heaters while used in indoor installation, must be connected to an exhaust pipe to vent the products of combustion outside. To maintain an adequate Oxygen rate, a minimum of 80 m³/h airflow from outside must be ensured. Direct-fired heaters are intended for use in outdoor open areas or in indoor well-ventilated areas. For indoor use, provide permanent ventilation openings of at least 25 cm²/kW, equally distributed between floor and high level, with a minimum of 250 cm².

• Only install the heater in normal upright position.
• DO NOT place the heater near walls, corners or low ceilings.
• DO NOT place the heater below a socket outlet.
• DO NOT place the heater on moving vehicles or where it can tip over.
• Keep the heater away from flammable, combustible, explosive or corrosive materials.
• Keep the heater away from curtains or similar materials that could block the air inlet and outlet.
• Never block or restrict the air inlet and outlet for any reason.
• Keep the power cable away from heat sources, sharp edges, cutting and moving parts.
• DO NOT expose directly to the weather or to excessive humidity.
• DO NOT place the heater in the immediate surroundings of a bath, shower or swimming pool.

Follow general and special fire safety regulations in force in all fields of applications. In any case ensure the following minimum safety clearances from materials or objects in the surroundings of the heater:

• Side: …………………………………………………………………….. 1 m
• Air inlet side: …………………………………………………………. 1 m
• Top: ………………………………………………………………….. 1.5 m
• Hot air outlet side: …………………………………………………. 3 m

Floors and ceilings must be made of fireproof materials in the place where the heater is operated. DO NOT connect direct-fired heaters to air ducts.

OPERATION

START-UP
Fill tank with clean fuel. Only use diesel or kerosene. Check fuel level using The fuel gauge on top of the tank. Connect the power cable plug to an AC220V- 240V 50 Hz earthed electrical supply system.

WARNING! Earthing is mandatory

• After completing the “start-up” steps above, the left display window shows “–”, the right display window shows the ambient temperature value.
• Push the power switch to the “on” position.
• The default ‘set temperature’ is 20°C, it is displayed on the left-hand window.
• If the ambient temperature is lower than the default temperature, after waiting for 12 seconds per ventilation, the heater starts.
• If the ambient temperature is higher than the default temperature, turn the thermostat control knob to the desired temperature. After waiting for several seconds of pre-ventilation, the heater starts.

WARNING!

ABNORMAL OPERATION:
In case of malfunction (flame failure, reduced airflow, bad combustion, etc.) the heater will stop, the LOCK-OUT MODE code will be shown on the display window; see Troubleshooting.

MANUAL RESET/RESTART
If the heater is in lock-out mode, check and resolve the cause of lock-out before restarting the heater. To reset, turn the ON/OFF switch to 0 and then (afters 30 sec) turn the ON/OFF to I. In case of repeated malfunction, call Technical Service. Turning the thermostat control knob will NOT reset the heater.

SHUT-DOWN
Move the switch to the “OFF” (O) position. The post-ventilation phase will cool down the combustion chamber for 90 seconds. Unplug the unit when not used for a long time.

• DO NOT disconnect the heater from the mains to stop it while in operation. Always allow the cooling sequence to be completed, otherwise, the residual heat could damage internal components.
• DO NOT cover the heater. DO NOT block the air inlet and outlet.
• The heater outlet is very hot during operation and after use. DO NOT touch! Use personal protecting equipment if needed.

MAINTENANCE

• Regularly wipe the cover using a soft sponge or cloth. For very dirty parts, use a sponge wetted with lukewarm water and a mild detergent, then dry using a clean cloth.
• Keep air inlet and fan free from dust and dirt. To clean inner parts, gently blow compressed air through air inlet.
• Regularly inspect the power cable: if worn, cracked or damaged have it replaced by technical service.
• Before storing the heater, make sure it is perfectly cool and dry. Cover the unit with a plastic bag, put it in its packing box and store it in a dry, ventilated place.
• Before starting any maintenance task, shut down, unplug and let the heater cool down for at least 15 minutes.
• DO NOT attempt any electrical repair yourself. If the heater needs service or repair, contact a qualified technician.
• DO NOT use a faulty unit unless a qualified technician has inspected and repaired it.
• When cleaning, make sure that water does not enter the unit.
• DO NOT open the enclosure to clean the inner parts. DO NOT spray water into the heater.
• Never use solvents, gasoline, toluene and similar aggressive chemicals to clean the heater.
