9. ORDINARY MAINTENANCE

IMPORTANT: During maintenance or cleaning, be sure that the light in the working area is sufficient. If necessary,
use an additional source of light. Exercise caution also when near the hot and moving parts marked with the rele-
vant symbol. The use of heavy-duty gloves is recommended.

CLEANING THE CABINET

1) Clean all outer parts of the cabinet weekly using only a soft dry cloth. Never clean it using inflammable or scou-
ring agents, alcohol, acetone or solvents. NEVER CLEAN THE CABINET BY THE USE OF WATER JETS. Clean glass
surfaces using glass-cleaning products only. The use of water is not recommended here, as it may cause calcium
deposits to build up.
GLASS SLIDERS to keep sliders running smoothly, when doing the weekly cleaning remove all dirt and dust that
may have built-up on the frame. As for crown-head curved sliders, an ad-hoc "lubricating pen" is supplied with the
equipment, which needs to be used when sliding covers no longer run smoothly. After cleaning, lubricate the frame
in which covers slide using the ad-hoc pen.
It is advisable to regularly check that the perimetric gasket around the glazing is in good working order.
2) Keep internal parts perfectly clean. Internal cleaning entails defrosting, which must be carried out whenever frost
thickness exceeds 5 mm, as it may have negative effects on the performance of the refrigerator. However, the cabi-
net can be defrosted sooner if display purposes recommend it. Defrosting should be accomplished as follows:
a) Empty the cabinet, store its contents in coldrooms or freezers that are adequate for keeping the requisite pre-
servation temperature.
b) Start defrosting as explained in section 8 "Description of controls".
c) Wait until the case reaches ambient temperature and check that no trace of ice remains on the walls. Do not
remove the ice by the use of metal or other sharp tools that may damage the walls.
d) Carefully clean the inside of the case with lukewarm water and mild soap. Then wipe thoroughly with a soft cloth.
e) After having carefully checked that the inside surfaces are perfectly dry (otherwise let them dry on), close the sli-
ders and switch the freezer on again.
f) Allow a couple of hours before loading the products back again.
If you wish to put the cabinet out of service, disconnect it from the power mains and follow the steps above, but
leave the sliding lids open to avoid mouldy odour.
Any maintenance operation not dealt with above, must be carried out by the authorized after-sales service or by
qualified personnel.

10. EMERGENCY SITUATIONS

1) The cabinet will not start or will not keep on working:
• there may be a general blackout;
• the wall master switch may be off;
• The plugs of the equipment may be not properly connected to the power outlet..
If power failure is not due to any of the above causes, call the nearest after-sales service immediately, empty the
cabinet and store the foods in coldrooms or refrigerators that may ensure their preservation temperature.
2) The cabinet will not cool properly
