8. MAINTENANCE
Before carrying out any cleaning operation, disconnect the unit from the power supply and place the main
switch in the
The units are equipped with a drainage outlet to make cleaning easier, as well as allowing for the eventual seepage of liquids from the foods.
During cleaning, the drainage outlet cover has to be removed and cleaned in order to avoid being blocked by solid elements being pulled into it.
The good operation and performance of the unit will largely depend on its correct maintenance, carried out periodically.
The manufacturer is exempt from all liability arising from non-compliance with the procedures contained in this manual.
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.
We recommend that this operation is carried out at least once every three months and at the start of every summer.
EVAPORATORS

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 aluminium. Only water with well-diluted neutral detergents should be used or products especially
designed for cleaning the evaporators of refrigerated units. Thecleanertheunit, thegreatertheenergysaving.
AUTOMATIC EVAPORATION TRAY
•
Onlyforspecialistpersonnel
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.
The duration and number of defrosts the refrigerating equipment is regulated at the factory. The user should not change this regulation.
Attention should be given to this tray and regular cleaning is recommended.
