WARNING !!!: Carefully read this service manual before you start
to use the heater. The instructions contained herein will allow you
to use the appliance in a safe manner.
Make sure the power supply cable has not been damaged. If the
supply cord is damaged, it must be replaced by the manufacturer, its
service agent or similarly qualified persons in order to avoid a hazard.
Moreover, check if the technical parameters of power supply source
comply with the requirements specified on the rating plate.
Place the appliance in its upright position. Make sure the switch is in
its "0" position shown in Fig. 4. Connect the heater to the power
supply source. Turn the switch and leave it for 5 seconds in the
positions as follows:
•Fan only: Fig. 5;
•1

5.
Turn the switch to its "0" position. Once the heating is off, leave the
fan operating for 3 minutes.
6.
The temperature in the room may be set by means of the control knob
(Fig. 8, page 2). Once the pre-set temperature is produced, the
thermostat will automatically switch the heating elements off while
the fan will continue to operate thus protecting the appliance from
overheating. If the temperature falls down beyond the pre-set value,
the system will switch the heating elements on again.
7.
The appliance has been equipped with an integrated thermal circuit
breaker ensuring high safety level. The breaker will automatically
switch the power supply off once a limit temperature is exceeded.
Should it happen, let the appliance cool down and only then, look for
the reason of the problem. Next push the "RESET" button (Fig. 8)
with a pointed tip in order to unlock the thermal circuit breaker. If the
heater does not operate, contact the seller or approved service centre.

Should the appliance remain idle for a long period of time, clean
it before shoving by blowing the inside with compressed air. The
heater should be kept in a dry and clean place. Before you start using
it again make sure the power supply cable has not been damaged. In
the case of any doubts contact the seller or approved service centre.
