7 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) When requesting assistance or spare parts,identify the machine's
model number and serial number (located on the unit's serial label)
and provide to Parker or an authorized Parker distributor.
c) Circuits containing 5t < xx < 50t of CO2 should be checked annu-
ally to identify any potential leaks.
Per European Regulation EU No. 517/2014 art. 4.3.a, 4.3.b) - Circuits
containing 50t < xx < 50t of CO2 should be checked for leaks every
6 months.
d) Per European Regulation EU No. 517/2014 art. 6 - Machines con-
taining 5t CO2 or more, the operator must keep a written record of
the quantity and type of refrigerant used, added or recovered during
maintenance/repair and fi nal disposal.
