3.
After about 10 minutes, the vacuum meter (10) should indicate the under pressure value at about -0.70 ÷
-0.76 bar; if the vacuum is lower, verify the connections to find the air leak.
4.
It is possible to reduce the noise generated by the compressed air venturi, by connecting a 10x12 mm
tube with a maximum length of 5 metres to the outlet of the economizer (5) ; this can reduce the yield of
the vacuum group and limit the vacuum creation.
9.5.
Vacuum switch
The vacuum switch (optional) allows the reduction of compressed air consumption, because the vacuum
ejector is turned off, when reaching a set vacuum degree.
Through the setting screw on the vacuum switch, the setting point of the vacuum can be regulated.
