SPECIAL MAINTENANCE
5.1
PRELIMINARY SAFETY OPERATIONS
WARNING! Before performing any maintenance operation stop
the appliance and cut the power supply by turning the main
switch (fig. 29 item N) to "0", then disconnect the power supply
by disconnecting the power cable from the power socket.
Turn off the gas supply by closing the main tap.
Operations must only be carried out after the appliance has
cooled down.
The working area must be properly illuminated if used during
the night or if visibility is poor.
All maintenance operations and repairs must be carried out
using suitable accident prevention equipment, by specialised and
properly licensed technicians, approved by the manufacturer.
The oven door protected by a padlock (fig.16, item H) can only
be opened by specialist technicians who are familiar with the
potential risks and using the relevant protective equipment.
All precautions are to keep the appliance in a proper state, and
failure to observe them might result in severe damage that will
not be covered by the guarantee, and in unnecessary risks.
WARNING! Periodically, at least once a year, and every time a
malfunction occurs, have a specialist technician check the
appliance over to ensure it is working properly; on this occasion,
check that the safety thermostat is operating correctly.
When any maintenance operations are carried out on the gas
circuit, use LOCTITE 577 as a sealing agent

GENERAL CLEANING
WARNING! When sliding the parts out from the inside of the
baking chamber, there is a risk of encountering cutting edges
(fins on heating elements, etc.), which is why all such operations
need to be performed with the proper protective equipment
(gloves, goggles, etc ...) and by staff informed of the risks and
able to take the utmost care.
After carrying out the operations described in point 5.1 above, clean
the appliance as follows:
Regularly clean the appliance in general. After leaving it to cool
down, carefully remove, from internal and external parts, all residues
that might have collected during cooking, using a damp sponge or
cloth and a little soapy water, if necessary. Rinse and dry the areas,
being sure to wipe parts with satin finish in the direction of the finish.
NOTE: At the end of cleaning, the internal blowers need to be
fitted in their original positions. If the air pipes are incorrectly
fitted, the cooking characteristics will be altered.
WARNING! Carefully clean off any fat or grease that may have
dripped during cooking on a regular basis, as this is a potential
fire hazard.
WARNING! Never clean the appliance with direct jets of water
or with pressurised water jets. Do not allow water or any
cleansers used to come into contact with electrical parts.
The use of toxic or harmful detergents is prohibited.
NOTE: Do not clean the tempered glass in doors while it is still
hot. Do not use solvents, detergents containing aggressive
substances (chlorides, acids, corrosives, abrasives, etc. ...) or
equipment that could damage surfaces. Before starting up the
appliance again, make sure that none of the cleaning equipment
has been left inside.
