GAS CONDENSER
The incorrect maintenance and lack of cleaning of the gas condenser of the refrigerated unit can
considerably reduce the performance of the unit as well as shortening the life of the compressor
motor. The cleaner the unit, especially the condenser fins,
the greater the energy saving
.
In any event, it is recommended that this task is
carried out by a service technician
. In the case of
any doubt, please contact your distributor.
The cleaning of the gas condenser must be carried out with the unit unplugged and removing the
protectors (grills) or taking out the condenser unit (depending on the model).
In order to remove the dirt deposited between the condenser fins, any of the following procedures
are recommended:
• Use a toothbrush or soft-bristle brush
• Blow the dirt using a suitable appliance
• Use air pressure to remove the dirt
We recommend that this operation is carried out at least
once every three months and at the start of every sum-
mer.

EVAPORATORS
Only for specialist personnel
The only maintenance the evaporators require is proper cleaning. This has to be done with the
machine stopped and once the ice that may be present on the fins has melted or once defrosting
has been done by operating the controls. This process may be accelerated by using warm water,
NEVER
using hard or sharp objects.
In order to clean the coil or the casing,
DO NOT
use chemical de-greasers with acid compounds
or bleach, chlorine, ammonia or salts as all these products aggressively attack copper and alu-
minium. Only water with well-diluted neutral detergents should be used or products especially
designed for cleaning the evaporators of refrigerated units. The cleaner the unit,
the greater the
energy saving
.

AUTOMATIC EVAPORATION TRAY
Only for specialist personnel
The majority of the units are equipped with an automatic evaporation tray for the situations where
an external outlet is not available to collect the defrosted water from the evaporators. If this tray
is not included, the drainage tubes have to be connected directly to the appropriate device or a
receptacle should be positioned in order to collect the water.
The defrost water can also cause breakdowns as the piping that brings the heat necessary for the
water to evaporate can be punctured or the electrical resistance can deteriorate.
Attention should be given to this tray and regular cleaning is recommended.
