Prolonged Inactivity
If the appliance remains inactive for a long period,
proceed as follows:
1. Use the automatic disconnecting switch to
deactivate connection to the main electrical
line.
2. Clean the appliance and surrounding areas
thoroughly;
3. Spread a thin layer of cooking oil onto the
stainless steel surfaces;
4. Carry out all maintenance operations;
5. Leave the doors ajar to prevent the formation
of mould and/or unpleasant odours.
Recommendations for normal use
In order to ensure correct use of the appliance, it
is advisable to apply the following
recommendations:
 Do not obstruct the front and rear zones
above the condensing unit in order to favour
heat disposal from the condenser to a
maximum.
 Always keep the front of the condenser clean
using a soft brush and do not use rigid or
metal tools that may damage the condenser
fins.
 Check the planarity of the appliance rest
surface.
 Do not introduce liquid or solid substances at
temperatures above the environmental
temperature and, however, introduce the
material after the appliance has reached the
functioning temperature.
 Do not stack the materials to be preserved in
contact with the internal walls, so blocking the
circulation of air, which guarantees uniformity
of the internal temperature of the refrigerated
compartment.
 Limit the number of times and the duration of
time the doors are open to a maximum.
8. CLEANING AND MAINTENANCE
8.1. Recommendations for Cleaning and Maintenance
! Activate all envisioned safety devices before
carrying out any maintenance interventions. In
particular, deactivate the electrical power supply
using the automatic isolating switch.
During maintenance, the cable and plug must be
visible to the operator performing the operation.
Do not touch the equipment with wet or damp
hands or bare feet.

8.2. Routine Maintenance
Routine maintenance consists of daily cleaning of
all the parts which can come into contact with
foodstuffs.
Correct maintenance allows the user to maximise
performance levels and operating life and
constantly maintain safety requirements.
Do not spray the appliance with direct jets of
water or high pressure appliances.
When cleaning stainless steel, do not use iron
wool, brushes or scrapers as ferrous particles
could be deposited which, on oxidising, could lead
to rust.
To remove hardened residues, use wooden or
plastic spatulas or abrasive rubber pads.
During long periods of inactivity, spread a
protective layer on all stainless steel surfaces by
wiping them with a cloth soaked in Vaseline oil
and airing the rooms periodically.
! Do not use products which contain
substances which are harmful and dangerous for
personal health (solvents, petrol etc.).
8.3. Routine Maintenance (350+350)
In these models, the two cells have a different
cooling and defrosting system.
In the upper ventilated cell, defrosting takes place
automatically at regular periods by the passage of
hot air. The condensation that is formed is
conveyed into the appropriate tank under the
compressor and then evaporated. No operation is
therefore required by the user.
In the lower static cell, defrosting takes place by
stopping the machine and frequency is at the
user's discretion.
Perform the operations stated below:
1. Switch the lower compartment off by
acting on the relevant switch
2. Empty the cell, removing the products
contained
3. Leave the door open for the time
necessary until the ice formed on the
walls melts; if necessary, ease
detachment from the walls using the
appropriate scraper supplied.
4. Clean well, dry the cell and reposition the
cap before re-starting the appliance.
8.4. Extraordinary Maintenance
! Extraordinary maintenance operations must
be carried out by skilled technical staff, equipped
with all personal protective devices.
! It is forbidden to remove or tamper with
guards and safety devices while the machine is
running.
! Procedures for topping up the refrigerant
and repairing gas leaks may only be carried out
by personnel who meet all the requirements of the
regulations in force in the country where the
equipment is used.
! In the case of flammable refrigerant gases,
R290, R600a or other hydrocarbons, disconnect
the machine from the power supply and
completely purge the refrigerant circuit with an
inert gas before proceeding with welding or other
work requiring flames or sparks.
! For refrigerant gases such as R452A, R134a
or other greenhouse gases comply with the
