4.7 Automatic
restart
In the event of a power failure, when power is restored the chiller will
assume the On-Off status held at the moment the power was lost.
5 Maintenance
a) Th
e machine is designed and built to guarantee continuous opera-
tion; however, the life of its components depends on the mainte-
nance performed.
b) When requesting assistance or spare parts, identify the machine
(model and serial number) by reading the dataplate located on the
unit.
c) Circuits containing 3 kg or more of refrigerant fl uid are checked to
identify leaks at least once a year.
Circuits containing 30 kg or more of refrigerant fl uid are checked to
identify leaks at least once every six months. (CE842/2006 art. 3.2.a,
3.2.b).
d) For machines containing 3 kg or more of refrigerant fl uid, the op-
erator must keep a record stating the quantity and type of refrigerant
used, an quantities added and that recovered during maintenance
operations, repairs and fi nal disposal (CE842/2006 art. 3.6). An
example of this record sheet can be downloaded from the site: www.

5.1 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 malfunction-
ing.
Y
In case of refrigerant leakage, contact qualifi ed and authorized
personnel.
Y
Th
e Schrader valve must only be used in case of machine malfunc-
tion: otherwise any damage caused by incorrect refrigerant charging
will not be covered by the warranty.
5.2 Preventive
maintenance
To guarantee lasting maximum chiller effi
ciency and reliability, carry
out:
a)
Z
every 4 months -
clean the condenser fi ns and make sure com-
pressor electrical absorption is within the dataplate values;
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;
3.
P3 pump kit;
c)
individual spare parts.
5.3 Refrigerant
Z
Charging: any damage caused by incorrect charging carried out by
unauthorized personnel will not be covered by the warranty.
Y
At normal temperature and pressure, the R407C refrigerant is a
colourless gas classifi ed in SAFETY GROUP A1 - EN378 (group 2 fl uid
according to Directive PED 97/23/EC);
GWP (Global Warming Potential) = 1652,5.
!
In case of refrigerant leakage, air the room.
5.4 Dismantling
Th
e refrigerant and the lubricating oil contained in the circuit must be
recovered in conformity with current local environmental regulations.
Th
e refrigerant fl uid is recovered before fi nal scrapping of the equip-
ment (CE 842/2006 art.4.4).
