VACUUM PUMP

Perform the operations listed below on a routine basis in order to ensure good operation of the
vacuum pump:
M1) Oil top-up.
M2) Oil change.
When refilling or replacing the pump oil, use only the oil recommended by the manufacturer.
Contact your retailer for information concerning the correct type of oil.

M.1) Oil top-up

This operation must be performed when the level of the oil falls to less than half on the indicator
(4) (refer to Figure 10). NOTE: in order to correctly check the oil level, run the pump for at least
1 minute (running a vacuum procedure in the hose for 1 minute) so that the oil fluidifies. Check
the oil level when the pump stops. To refill the oil, perform the steps listed below in the order
given. Disconnect the MACHINE from the mains supply. Locate the oil cap (2) and screw it
completely off. The oil must be added through the hole in which the oil cap was lodged (2). Add
oil a little at a time, waiting for the level to rise before each successive addition, until the oil level
is about ½ cm above the red mark on the indicator (4). Replace the oil cap (2) and tighten
down.

M.2) Oil change

The vacuum pump oil must be replaced every 150 working hours and in any case every time
the refrigerant filters are replaced. 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 500 cc capacity in which to collect the used oil. The pump contains about 500 cc of
oil. Use only the oils recommended by the manufacturer (consult your retailer).
1) Disconnect the machine from the mains supply.
