E) MAINTENANCE
E.1 ORDINARY MAINTENANCE
ATTENTION: The user must never open the FREEBLOCK
unit. The manufacturer declines any responsibility for damage
to persons or things and for malfunctioning caused by
interventions effectuated by unauthorised personnel.
For good functioning of the unit, it is recommended to clean
the fins of the condenser positioned on the opposite side to the
fans every two or three months. This must be effectuated using
a jet of compressed air or with a long-haired brush and without
opening the FREEBLOCK unit. Ensure that there is always a
sufficient exchange of air if FREEBLOCK unit is installed in a
closed environment.
If a fluorescent tube should burn out, substitute it with one of
the same wattage and switching off the mains current to the
unit beforehand.
E.2 EXTRAORDINARY MAINTENANCE
ATTENTION: All extraordinary maintenance operations must
be effectuated by qualified personnel according to the
methods described in this instruction manual.
IMPORTANT: Before any maintenance operation or cleaning,
switch off the mains current to the machine.
ATTENTION: If the power cable is damaged, do not use the
FREEBLOCK and do not attempt to repair it: it must be
replaced by the manufacturer or by his after-sales service.
F) FUNCTIONING FAULTS
1 - The compressor blocks
This denotes an abnormal rise in temperature of the
refrigeration cell. The compressor is equipped with a safety
device that stops the compressor when a dangerous situation
is verified, such as the following:
Poor functioning of the condenser fan
-
Condenser dirty (see point E.1)
-
Voltage overload in the electrical mains system
-
Excessive environmental temperature (insufficient
-
exchange of air)
It must be remembered that after stopping the compressor
starts automatically but it is better to remove the problem that
caused the stoppage. Call a technician if the problem persists.
2 – Formation of ice on the evaporator
Possible causes could be:
Incorrect setting of the thermostat (for FB positive
-
cells)
Too many openings of the cell door (see point D.4)
-
Introduction of goods at a temperature more than
-
foreseen (not more than 20°C for positive cells and
not more than -14°C for low-temperature cells).
ATTENTION: There is a rise in temperature during the
defrosting phase. This allows the evaporator to free itself of
formations of ice or frost. Defrosting is signalled by the
switching on of the LED
of the electronic instrument.
G) DISMANTLING AND DISPOSAL
ATTENTION: The equipment contains oil, flammable
refrigerant gas, parts in plastic, metallic parts and glass. At the
end of the life cycle of the unit, avoid dispersing the refrigerant
gas R452a and the POE oil in the environment.
ATTENTION: Dismantling operations must be carried out by
qualified personnel.
Dismantle the unit, grouping the components according to
their chemical nature.
Temporary storage of special waste materials is permitted
whilst waiting for disposal by definite treatment and/or storage.
The laws in force in the country must be observed by the user
with regards to environmental protection.
In the various countries, different legislations are in force,
therefore the regulations imposed by the laws and authorities
of the countries where the demolition occurs must be
observed.
