6 Maintenance
a) e machine is designed and built to guarantee continuous opera-
tion; however, the life of its components depends on the mainte-
nance 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 malfunction-
ing
Y In case of refrigerant leakage, contact quali ed and authorized per-
sonnel.
Y e 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.

e equipment contains uorinated greenhouse gases.
At normal temperature and pressure, the R134a refrigerant is a colour-
less gas classi ed in SAFETY GROUP A1 - EN378 (group 2 uid ac-
cording to Directive PED 2014/68/EU)
GWP (Global Warming Potential) = 1430.
! In case of refrigerant leakage, ventilate the room.
