4.7 Automatic restart
In the event of a power failure, when power is restored the chiller will
assume theOn-Off statusheld at themoment the power was lost.
5 Maintenance
aa) The machine is designed and built to guarantee continuous opera-
tion; however, the life of its components depends on the mainte-
nance 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 refrigerant used, an quantities
added and that recovered during maintenance operations, repairs
and nal disposal ((EU) No. 517/2014 art. 6). .An example of this
record sheet can be downloaded from the site: www.polewr.com.
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 quali ed and authorized
personnel.
Y The Schrader valve must only be used in case of machine mal-
function: otherwise any damage caused by incorrect refrigerant charg-
ing will not be covered by the warranty.
5.1 Preventive maintenance
To guarantee lasting maximum chiller ef ciency and reliability, carry out:
Z every month - clean the condenser ns (for biogas version);
Z every 6 months - clean the condenser ns and make sure com-
pressor electrical absorption is within the dataplate values;
Z Maintenance (par.7.7)
a) kit for maintenance;
b) service kit;
c) individual spare parts.
5.2 Refrigerant
Z Charging: any damage caused by incorrect charging carried 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 colour-
less gas classi ed in SAFETY GROUP A1 - EN378 (group 2 uid ac-
cording to Directive PED 2014/68/EU);
GWP (Global Warming Potential) = 1774.
! In case of refrigerant leakage, air the room.
5.3 Dismantling
The refrigerant and the lubricating oil contained in the circuit must be
recovered in conformity with current local environmental regulations.
The refrigerant uid is recovered before nal scrapping of the equip-
ment ((EU) No. 517/2014 art.8).
