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. ((EU) No. 517/2014 art.
4.3.a, 4.3.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 ((EU) No. 517/2014 art. 6). An
example of this record sheet can be downloaded from the site: www.

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

5.2 Preventive maintenance

To guarantee lasting maximum chiller effi ciency and reliability, carry
out:
Z
a) every 4 months - clean the condenser fi ns and make sure com-
pressor electrical absorption is within the dataplate values;
Z
b) yearly - W version: in case of encrustations inside the con-
denser, introduce and circulate a specifi c detergent liquid.
Z
b) Every 3 years - installation of kit for maintenance every 3
years. (Par.7.7)
a) kit for maintenance every 3 years;
b)service kit;
1. compressor kit;
2. fan kit;
3. P3 pump kit;
4. expansion valve 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 2014/68/EU);
GWP (Global Warming Potential) = 1774.
!
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 ((EU) No. 517/2014 art.8).
