Regularly wipe the enclosure 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.
8.2.
Keep air inlet and fan free from dust and dirt. To clean inner parts, gently blow compressed air through air inlet.
8.3.
Regularly inspect the power cable: if worn, cracked or damaged have it replaced by technical service.
8.4.
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.
8.5.
LONG TERM STORAGE
If the heater is to be stored for a long period of time, drain the fuel through the fuel cap opening. Rinse and swirl a small amount of fuel
within the tank and then empty it fully. When you come to use the heater again do not use old fuel which has been stored from the
previous season. Use of old fuel can damage your heater.
Although our heaters operate with diesel fuel, when the temperature is below 0°C diesel additives are required to maintain the diesel's
viscosity. Typically diesel can cloud in freezing conditions and will start to gel. You will need additives for your fuel in these conditions.
Kerosene does not start to gel until the ambient temperature is around -40°C.
Refer to fig.1B.
DO NOT use paraffin in these heaters.
8.6.
MAINTENANCE
The following checks BY QUALIFIED PERSONNEL ONLY are recommended before
every seasonal use:
8.6.1.
Nozzle
Carefully unscrew nozzle from nozzle fitting. Blow compressed air through nozzle orifice
to free it from dirt. Replace nozzle if necessary.
8.6.2.
Air Filters
Clean air filters. Remove filter end cover (11), wash air intake filter (10) using a light
detergent and dry it thoroughly before re-installing.
Replace air delivery filter (9) once a year fig.2.

Ignition Electrodes fig.3
8.6.3.
Clean and if necessary replace the ignition electrode. For electrode gaps see fig.3.
fig.3
Compressor Pressure Adjustment fig.4
8.6.4.
WARNING! The compressor pressure is factory set and must be checked by qualified technicians only. Tampering with the
‰
unit may be dangerous.
Remove pressure gauge cap. Connect a pressure gauge on the pressure measuring port on the rear guard. Start heater and read
air pressure value. If necessary adjust pressure to correct value by turning the adjusting screw (the air vent hole in the adjusting screw
middle) clockwise to increase, anticlockwise to decrease the pressure.
