MAINTENANCE
VACUUM PUMP
Perform the operations listed below on a routine basis in order to
ensure good operation of the vacuum pump.
When replacing the pump oil, use only the oil recommended by
the manufacturer. Contact your retailer for information
concerning the correct type of oil.
The vacuum pump oil must be replaced every 15 hours of
functioning and in any case every time the refrigerant filters are
replaced.
NOTE: Alarm message is visualized, to remove alarm message
refer to VACUUM PUMP OIL CHANGE paragraph.
The oil must also be replaced whenever it changes color due to
absorption of humidity. Before beginning the oil change
procedure, procure a container of at least 17 oz (500 cc) capacity
in which to collect the used oil. The pump contains about 14.9 oz
(440 cc) of oil. Use only the oils recommended by the
manufacturer (consult your retailer). The use of a non-
recommended oil may impair the proper functioning of the
pump and void the warranty.
Disconnect the machine from the main supply.
Place a container (ref 4, Fig. 23). under the drain cap (ref 2, Fig.
23).
