6 Maintenance
a) Th e machine is designed and built to guarantee continuous opera-
tion; however, the life of its components depends on the maintenance
performed;
b) 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 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 ope-
rator 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.

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 malfunctio-
ning.
For models PST460 to PST1200 , in case of maintenance to the fl anged
air connections, replace the seals using only the spare parts indicated in
par. 8.4.
Y
In case of refrigerant leakage, contact qualifi ed and authorized per-
sonnel.
Y
Th e Schrader valve must only be used in case of machine malfun-
ction: 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.

Y
Th e equipment contains fl uorinated greenhouse gases.
At normal temperature and pressure, the R407c refrigerant is a co-
lourless 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, ventilate the room.
