4.4. EXTRAORDINARY MAINTENANCE
4.4.1. How to access the electronic boards and the
electrical control panels.
4.4.2. Cleaning the condenser
The information and instructions in this paragraph are
destined exclusively to the specialised staff authorised
to intervene on the electrical and refrigerator compo-
nents of the machine.
The electronic boards and the electrical control panels
are located on the top part of the machine, protected by
a metal sheet. Remove the electrical power supply
before intervening for maintenance. Then remove the
steel cover, unscrewing the locking screws.
At the end of maintenance operations, accurately reas-
semble the covers and tighten the locking screws.

For correct and efficient functioning of the cabinet
holder, the air condenser must be kept clean in order to
allow the free circulation of the air. This operation must
be performed every 30 days maximum. It can be carried
out using non-metal brushes in order to remove all of
the dust and soot from the condenser fins themselves.
The use of a suction device is recommended in order to
prevent the dispersion of the dust removed into the
environment. Whenever there are greasy deposits, use
a brush soaked in alcohol.
Do not scrape the surfaces with sharp or abrasive
bodies.
During the above-mentioned operations, always
wear protective gloves, glasses and masks for protection
of the respiratory tract.
