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 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 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.
6.2 Refrigerant.
Charging: any damage caused by incorrect refrigerant replacement car-
ried out by unauthorized personnel will not be covered by the warranty.
Z
Y
The equipment contains fl uorinated greenhouse gases.
At normal temperature and pressure, the R513A refrigerant is a colour-
less gas classifi ed in SAFETY GROUP A1 - EN378 (group 2 fl uid accord-
ing to Directive PED 2014/68/EU)
GWP (Global Warming Potential) = 573.
!
In case of refrigerant leakage, ventilate the room.

c) individual spare parts.
6.4 Dismantling
Maintenance Interval The refrigerant and the lubricating oil contained in the circuit must be
recovered in conformity with current local environmental regulations.
tions) The refrigerant fl uid is recovered before fi nal scrapping of the equipment
