3.1 ROUTINE MAINTENANCE
Frequently check the state of the power cable and, if necessary,
request the assistance of the specialised technician to replace
it; have the appliance checked periodically (at least once a
year).
ATTENTION!
Disconnect the power supply before cleaning
the appliance.
3.2 PRECAUTIONS FOR MAINTENANCE
Routine maintenance operations can be carried out by non-
specialised personnel, carefully following the instructions
given below.
The manufacturer declines any liability for
operations carried out on the machine without following
these instructions.
3.2 CLEANING THE APPLIANCE AND ACCESSORIES
Before using the appliance, clean all the internal parts
and accessories with lukewarm water and neutral
soap or products that are over 90% biodegradable
(in order to reduce the emission of pollutants into
the environment), then rinse and dry thoroughly. Do
not use solvent-based detergents (e.g. trichloro-ethylene) or
abrasive powders for cleaning. It is advisable to go over the
stainless steel surfaces with a rag moistened with paraffin oil
in order to create a protective film.
ATTENTION!
Do not clean the machine with jets of water.
3.3 PRECAUTIONS IN CASE OF LONG IDLE PERIODS
If the appliance is not going to be used for some time, take
the following precautions:
• Close the cocks or main switches ahead of the appliances.
• Go over all the stainless steel surfaces vigorously with
a rag moistened with paraffin oil in order to create a
protective film.
• Have the appliance checked before using it again.
• To prevent too rapid evaporation of accumulated moisture
with consequent breakage of elements, switch electric
appliances on at minimum heat for at least 45 minutes
before reuse.
ATTENTION!
Put the machine in safe conditions before
starting any maintenance operation.
After carrying out maintenance, make sure
the machine is able to work safely and, in particular, that the
protection and safety devices are efficient.
ATTENTION!
Respect the requirements for the various routine
and extraordinary maintenance operations.
Non-compliance with the instructions can
create risks for personnel.
3.4 EXTERNAL PARTS
SATIN-FINISH STEEL SURFACES (daily)
• Clean all steel surfaces: dirt is easily removed when it has
just formed.
• Remove grime, fat and other cooking residuals from steel
surfaces when cool using soapy water, with or without
detergent, and a cloth or sponge. Dry the surfaces
thoroughly after cleaning.
• In case of encrusted grime, fat or food residuals, go
over with a cloth or sponge, wiping in the direction of the
satin finish and rinsing often: rubbing in a circular motion
combined with the particles of dirt on the cloth/sponge
could spoil the steel’s satin finish.
• Metal objects can spoil or damage the steel: damaged
surfaces become dirty more easily and are more subject
to corrosion.
• Restore the satin finish if necessary.
SURFACES BLACKENED BY HEAT (when necessary)
Exposure to high temperatures can cause the formation of
dark marks. These do not constitute damage and can be
removed by following the instructions given in the previous
section.
OTHER SURFACES
HEATED TANKS/CONTAINERS (daily)
Clean the appliance tanks or containers using boiled water,
adding soda (degreasing) if necessary. Use the accessories
(optional or supplied) specified in the list to eliminate
encrustations or food deposits.
IMPORTANT – With electrical equipment, make sure no
water comes into contact with electrical components: water
entering can cause short circuiting and dissipation, tripping
the appliance’s protection devices.
SURFACES IN SOFT IRON OR CAST IRON (daily)
Remove dirt using a damp cloth or, in case of encrustations,
the accessories (optional or supplied) specified in the list. After
cleaning, switch the appliance on to dry the surface quickly, then
protect the surface with a light film of cooking oil.
3.6 SCALE
STEEL SURFACES (when necessary)
Remove any scale (stains or marks) left by water on steel
surfaces using suitable natural detergents (e.g. vinegar) or
chemical (e.g. “STRIPAWAY” produced by ECOLAB).
3.7 INTERNAL PARTS (every 6 months)
IMPORTANT! Operations to be carried out only by
specialised technicians.
• Check the internal parts.
• Remove any deposits of dirt inside the appliance.
• Check and clean the discharge system.
• After the first month of use, it is advisable to clean and
re-grease the lifting system (screw and nut) to eliminate
any work residuals.
Subsequently, at least once a year, or when necessary,
lubricate the lifting system (tank hinges and lifting screw)
using a brush or grease gun..
NOTE ! In particular ambient conditions (e.g. intensive use
of the appliance, salty environment, etc.) the above-mentioned
cleaning should be more frequent.
