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.
Z
b) When requesting assistance or spare parts, identify the ma-
chine (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.

At normal temperature and pressure, the R134a 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) = 1430.
!
In case of refrigerant leakage, ventilate the room.

6.3 Desiccant agent

The desiccant agent used is not harmful; during the fi lling and emptying
of the tanks, observe the following warnings:
