4.7 Automatic restart
In the event of a power failure, when power is restored the chiller will
assume theOn-Off statusheld at themoment the power was lost.
5 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
(model and serial number) by reading the dataplate located on the
unit.
c) An example of this record sheet can be downloaded from the site:
www.polewr.com.
5.1 General instructions
! Before performing any maintenance, make sure the power to the
refrigerator is disconnected.
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
personnel.
Y The Schrader valve must only be used in case of machine mal-
function: otherwise any damage caused by incorrect refrigerant charg-
ing will not be covered by the warranty.
5.2 Preventive maintenance
To guarantee lasting maximum chiller ef ciency and reliability, carry out:
a)
Z every 6 months - clean the condenser ns and make sure
compressor electrical absorption is within the dataplate values;
b)
Z kit for maintenance (par.7.5)
• kit for maintenance;
• service kit;
• individual spare parts.
5.3 Refrigerant
Z Charging: any damage caused by incorrect charging carried out
by unauthorized personnel will not be covered by the warranty.
Y 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.
5.4 Dismantling
The refrigerant and the lubricating oil contained in the circuit must be
recovered in conformity with current local environmental regulations.
