6 Maintenance
a) The machine is designed and built to guarantee continuous
operation; however, the life of its components depends on
the maintenance performed.
b)
Z When requesting assistance or spare parts, identify the
machine (model and serial number) by reading the data plate
located on the unit.
c) Circuits containing 5t < xx < 50t of CO2 are checked to
identify leaks at least once a year.
Circuits containing 50t < xx < 500t di CO2 are checked
to identify leaks at least once every six months. ((EU) No.
517/2014 art. 4.3.a, 4.3.b).
d) For machines containing 5t CO2 ore more, the operator
must keep a record stating the quantity and type of refriger-
ant used, an quantities added and that recovered during
maintenance operations, repairs and nal disposal ((EU) No.
517/2014 art. 6).
6.1 General instructions
! Before performing any maintenance, make sure the power
to the refrigerator is disconnected.
Y Always use the Manufacturer’s original spare parts:
otherwise the Manufacturer is relieved of all liability regarding
machine malfunctioning.
Y In case of refrigerant leakage, contact quali ed and author-
ized personnel.
Y The Schrader valve must only be used in case of machine
malfunction: otherwise any damage caused by incorrect refrig-
erant charging will not be covered by the warranty.
6.2 Preventive maintenance
To guarantee lasting maximum chiller ef ciency and reliability,
carry out:
a)
Z every 4 months - clean the condenser ns and make
sure compressor electrical absorption is within the dataplate
values;
b)
Z yearly - W version: in case of encrustations inside the
condenser, introduce and circulate a speci c detergent liquid.
b)
Z Every 3 years - installation of kit for maintenance every
3 years. (par.7.4)
a) kit for maintenance every 3 years;
b)service kit;
1. compressor kit;
2. fan kit;
c) individual spare parts.
6.3 Refrigerant
Z Charging: any damage caused by incorrect charging car-
ried out by unauthorized personnel will not be covered by the
warranty.
Y The equipment contains uorinated greenhouse gases.
At normal temperature and pressure, the R407C refrigerant is a
colourless gas classi ed in SAFETY GROUP A1 - EN378 (group
2 uid according to Directive PED 2014/68/EU);
GWP (Global Warming Potential) = 1774.
! In case of refrigerant leakage, air the room.
6.4 Dismantling
The refrigerant and the lubricating oil contained in the circuit
must be recovered in conformity with current local environmen-
tal regulations.
The refrigerant uid is recovered before nal scrapping of the
equipment ((EU) No. 517/2014 art.8).
