4. The Physical System
• LIFCO/Frigoveneta® refrigeration units are equipped with DWM
COPELAND compressors charged with polyester oil, for working
with R507A ecological refrigerants (also R22).
• The compressors and motor compartment are connected by
anitvibrating bearing and leveling supports. They are used to
avoid the transmission of the vibrations made by the
compressor to all the surrounding frame.
• The chassis is made by hot – galvanised painted steel and it
could be placed outdoor. The panels are removable, by suitable
key, for maintenance operations.
• The vibration isolating bases are made by a gum vulcanizes to an
iron round plate with a central bolt screw for fixing the
compressor’s bearing to the beplate of the unit.
These vibrations, if they are not reduced, could cause a pipe burst
and noise.

5. The Physical System
• The electrical board is in a compartment inside the chassis and it is a
integrand part of the unit. It contains the power section, the electronical
control and the electrical security of the unit. It is made conforming to the
following standards: EN 60204-1, EN 60335-2-40, EMC 89/336/CEE
e92/31/CEE.
• All the refrigeration equipment are designed and assembled according to
the following standards and regulations: 97/23/CE;Machine directive
89/392/CE; 93/44/CE; 93/68/CE; Directive 73/23/CE. Low voltage;
Directive 89/336/CE, CEI EN 50081-1, CEI EN 50082-1. Electromagnetic
compatibility; Réfrigération Systems – Safety requirements UNI 8011, UNI
EN 378-1, UNI EN 378-2, UNI EN 378-3, UNI EN 378-4 UNI EN 12100-1, UNI
EN 12100-2, CEI EN 60204-1
• The refrigeration pipes, for hot, cold and liquid refrigerants are made by
copper tubes according to the directive EN 12735-1. The tubes are
sustained by fasteners.

6. The Electronical System
The electronical terminal PCO can allow to control the following parameters:
PARAMETERS YES
ON/OFF X
DATE AND HOUR X
SUCTION PRESSURE X
DISCHARGE PRESSURE X
AIR TEMPERATURE AT THE CONDENSER X
ENTRANCE
DIFFERENTIAL PRESSURE OF THE OIL X
PUMP
ALARMS X
REFRIGERANT TYPE X
TESTING DATE X

7. The Electronical System
ALL THE PARAMETERS COULD BE MODIFIED BY THE ELECTRONICAL TERMINAL PCO,
BY THE COMPUTER FOR THE LOCAL SUPERVISION OR BY THE COMPUTER FOR THE
SUPERVISION SERVICE IN LIFCO AND FRIGOVENETA
• The control board could be
programmed for a manual or
automatic starting after the end of
an alarm condition.
• All the alarms are registered with
the date and the hour of the event.
When an alarm will appear there
will be an acoustic and visual signal
on the computer for the local
supervision and, if the plant is
connected to the phone line, it will
be made an automatical call to the
service centre in Frigoveneta.

8. The monitoring system
FRIGOVENETA monitoring system includes all the
equipments that allows total control of the
Benefit of the monitoring
refrigerating installation by a central system
computer called "Local Supervisor", linked by
modem to our technical assistance center.
Some of the main properties of our system: • Grafics: allows for immediate temperature
adjustments which minimizes food waste.
• Grafics: it's possible to control the state of each
variable of the refrigerating equipment and • Alarms: ensures that the performance for each
of the cold rooms. cabinet is constantly monitored and any
faults are dealt with immediately .
• Alarms :register of every alarm occurred and of
every technical assistance center intervention • Filing ensures that a efficient and effective
(date and hour) maintenance program can be set for each
cabinet in view of its a history. This is
• Filing of more than two years for alarms and supporting evidence which allows you to pay
events. reduced premiums to Insurance companies
• HACCP :up-to-date with the Hazard Analysis • HACCP : used in the food industry to identify
and Critical Control Unit Points. HACCP is a potential food safety hazards, so that key
systematic preventive approach to food actions can be taken to reduce or eliminate
safety and pharmaceutical safety that the risk of the hazards being realized.
addresses physical, chemical, and biological PREVENTION IS BETTER THAN CURE.
hazards as a means of prevention rather
than finished product inspection.
The system will connect frequently to the technical assistance center, to test the correct working of the
refrigerating equipment; if there's something wrong, the system will download all data and alarms.
Technicians can organize in real time assistance intervention, or act directly on the system to solve the problem
occurred and to avoid other problems for the future.

9. The Warranty
• The warranty on LIFCO/Frigoveneta refrigerating plants is 18 months
long after delivery.
• Electric and electronic material are not covered by warranty.
• During the warranty period all the parts with fabrication fault will be
substituted.
• Warranty is no more valid if the fault on the refrigerating plants part
is due to bad use of the system, or to carelessness of the user.
• Are excluded from warranty:
– damages due to atmospheric disaster or fires;
– damages that are not due to the normal use of the products
– All the items subject to wear and tear.
• Warranty doesn’t cover any responsibility of direct or indirect
damage, and every compensation higher than reparation or
substitution cost.
• LIFCO/Frigoveneta is not responsible of cooled items damage.
• Damages that can occur during unload are excluded from warranty.
