n°1 filter direr, model XH412
n°1 bottle mineral oil for vacuum pump, model K1L
n°1 bottle of oil for compressor, model SW32
n°1 kit of gaskets, model G19020
6.2 Periodic operations
1. Check all swivel connections for tightening every 10 operations
2. Check the vacuum pump oil level; the oil must be changed at least every 100 hours of operation or
once every six months even if the unit is not used frequently. The pump must be off when checking the
oil level. Anyway, the unit will inform the operator when the oil must be changed.
6.3 Changing the vacuum pump oil
The vacuum pump oil must be change whenever the message “Change vacuum pump oil” appears
on the display when the unit is turned on.
The oil also needs to be changed whenever it becomes cloudy. Contaminated oil reduces vacuum
pump performances and irreversibly damages its mechanical components.
All draining and refilling operations must be performed when the pump is turned off.
To avoid reduction of the pump efficiency and to maintain its performances, use only K1L oil for
maintenance.
1. Before draining the oil, have the pump run for at least 10 minutes with the 82 and 83 valves closed.
2. Turn the recovery unit off by turning the 87 switch to position 0 and disconnect the power cord; strictly
observe the sequence of operations
3. Remove the front door ref. 53 of the unit
4. Unscrew the drain plug ref. 12 located at the bottom of the pump
5. Completely drain the oil
6. Screw the drain plug on again
7. Unscrew the filler plug ref. 10 situated on top of the pump
8. Slowly refill the pump with oil until the level covers half of the sight glass (ref. 11) located on the side
of the pump
9. Screw the oil plug on again and re-install the previously removed panel again
10. When the oil change procedure is completed, turn the unit on by turning the 87 switch to position 1
11. When the message “Change vacuum pump oil” appears on the display, if you press the key,
then the counter is set at zero.
