6 Maintenance
a) The 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.
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 quali 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.

Y The equipment contains uorinated greenhouse gases.
At normal temperature and pressure, the R5134a refrigerant is a colour-
less gas classi ed in SAFETY GROUP A1 - EN378 (group 2 uid accord-
ing to Directive PED 2014/68/EU)
GWP (Global Warming Potential) = 573.
! In case of refrigerant leakage, ventilate the room.
