WARNING:The electric power cable of the heater must
be earthed and must have a differential magnetothermal
switch.The electric plug must be connected to a socket
which has a disconnecting switch.
The heater can only work automatically when a control mecha-
nism, for example a thermostat or clock, is connected to it by at-
taching the cable to terminals 3 and 4 of plug 3 (Fig.2) supplied
with the product (the electric wire that links the two terminals
must be removed and remounted only if the heater is to be used
without the control mechanism).
To turn on the machine, do the following:
• If the control mechanism is connected, adjust it so that the
machine can function (for example, the thermostat must be set
to the maximum temperature).
• Flip switch 1 (Fig. 2) to the position with the symbol: ON – the
fan comes on and after several seconds the heater starts bur-
ning.
The fi rst time the heater is used, or after the fuel circuit has been
completely drained, the fl ow of fuel oil to the nozzle may be in-
suffi cient and may activate the fl ame cut out mechanism, which
will turn off the heater;if this happens, wait for about a minute
and then press the reset button 1 (Fig. 2) to start the machine
again.
The fi rst steps to take if the machine does not work are the
following:
1. Check that there is fuel in the tank.
2. Press the reset button 1 (Fig.2) ON.
3. If the heater still

TURNING OFF THE HEATER

To turn off the machine, move switch 1 (Fig. 2) to the "0" position
or adjust the control mechanism, for example turning the ther-
mostat to a lower position. The fl ame will go off and the fan will
continue to function until the combustion chamber has cooled
down completely.

SAFETY DEVICES

The heater is equipped with an electronic device to control the
fl ame.If there is an anomaly in the functioning, the machine will
be turned off and the reset button light 1 (Fig.2) will come on.
An over-heating thermostat cuts in and shuts off the fuel supply
if the heater overheats:the thermostat resets itself automatically
when the temperature in the combustion chamber diminishes
and reaches the maximum permitted value.
Before turning the heater on again, the cause of the overheating
must be identifi ed and removed (for example, a blockage in the
suction orifi ce and/or of the air fl ow duct, the non-functioning
of the fan). To turn on the machine again, press the reset but-
ton and repeat the specifi c instructions outlined in the section
"STARTING THE HEATER".
MOVING AND TRANSPORTING
THE HEATER
WARNING The following steps must be carried out befo-
re moving the heater: turn the heater off, following the
instructions in the previous section; disconnect the plug
from the power supply and wait for the heater to cool.
does not work, consult
Before lifting or moving the heater, make sure that the fuel tank
cap is fi rmly in place.
The heater may be supplied in a portable version, with wheels,
or a suspended version, mounted on a support structure and
fi xed in place with wires or chains. In the former case, to move
the heater, simply grasp the support handle and wheel the hea-
ter. In the latter case, the heater must be lifted with a fork-lift
truck or a similar piece of equipment.
PREVENTATIVE
CE PROGRAMME
To ensure that the heater continues to work properly, it is neces-
sary to periodically clean the combustion chamber, the burner
and the fan.
WARNING The following steps must be carried out befo-
re servicing the heater: turn the heater off, following the
instructions in the previous section; disconnect the plug
from the power supply and wait for the heater to cool.
Every 50 hours of use it is necessary to:
• Dismantle the fi lter cartridge, remove it and clean it with clean
fuel oil.
• Remove the exterior cylindrical casing and clean the inside
and the blades of the fan.
• Check the condition of the cables and the high voltage connec-
tions on the electrodes.
• Dismantle the burner, clean the parts, then clean the electro-
des and regulate them to the distance indicated on page 61 in
the
the electrode regulation diagram.
