6 Maintenance
a) 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 CO are checked to identify
2
leaks at least once a year.
Circuits containing 50t < xx < 500t di CO
2
leaks at least once every six months. ((EU) No. 517/2014 art. 4.3.a,
4.3.b).
d) For machines containing 5t CO ore more, the operator must keep a
2
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.polewr.com.

6.1 General instructions

!
Before any maintenance, make sure:
• the pneumatic circuit is no longer pressurized;
• the dryer is disconnected from the main power supply
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 qualifi ed and authorized per-
sonnel.
Y
The 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.
