Figure 7-9 on
page 7-15 shows the 307X with the E9946A vacuum
option installed.
Figure 7-10 on page 7-16 shows the
3279 and 79000 with the E9945A vacuum option
installed.
The factory default relay wiring is shown; however, the
vacuum solenoid (valve) is not voltage polarity
sensitive. The vacuum solenoid valves are air pressure
assisted with 280 kPa (40 psi) applied to each valve. A
vacuum filter is not shown, since the air passes through
the vacuum solenoid before the filter; however, you may
desire to install a filter to keep vacuum lines from
picking up unwanted materials.
1 Vacuum valve inside diameter (ID) is 0.75 inch and outside diameter (OD) is 1.5 inches.
