Y In case of refrigerant leakage, contact quali ed and author-
ized personnel.
Y The Schrader valve must only be used in case of machine
malfunction: otherwise any damage caused by incorrect refrig-
erant charging will not be covered by the warranty.
6.2 Preventive maintenance
To guarantee lasting maximum chiller ef ciency and reliability,
carry out:
a)
Z every 4 months - clean the condenser ns and make
sure compressor electrical absorption is within the dataplate
values;
b)
Z yearly - W version: in case of encrustations inside the
condenser, introduce and circulate a speci c detergent liquid.
b)

Z Charging: any damage caused by incorrect charging 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 R407C refrigerant is a
colourless gas classi ed in SAFETY GROUP A1 - EN378 (group
2 uid according to Directive PED 2014/68/EU);
GWP (Global Warming Potential) = 1774.
! In case of refrigerant leakage, air the room.
