Front Load Single and Dual Sensors Operating Manual
8 Connect the 3.175 mm (1/8 in.) air tube from the A port of the solenoid valve to
the quick disconnect fitting installed in step 7, see
section 3.4, Pneumatic
Connections, on page 3-4 .
9 Attach the P port of the solenoid valve to a source of air. The air supply must
be 70 psi (gauge) {85 psi (absolute)} (5.8 bar (absolute)) [584 kPa (absolute)]
(minimum) to 80 psi (gauge) {95 psi (absolute)} (6.5 bar (absolute))
[653 kPa (absolute)] (maximum), see
section 3.4, Pneumatic Connections, on
page 3-4 .
WARNING
Do not exceed 100 psi (gauge) {115 psi (absolute)}
(7.9 bar (absolute)) [791 kPa (absolute)].
Connection to excessive pressure may result in personal
injury or equipment damage.
CAUTION
Maximum temperature for the solenoid valve assembly
is 105 °C for bakeout and operation.
10 Make electrical connections to the solenoid valve (see section 3.5, Electrical
Connections, on page 3-4 ).
3.3 Installation with a CF40 (2-3/4 in. ConFlat) Feedthrough
If the solenoid valve assembly is to be used with the CF40 (2-3/4 in. ConFlat)
feedthrough, modify the valve bracket as follows (see
Figure 3-2 on page 3-5 ).
1 Align the score line on the solenoid valve bracket over the edge of a table or
other square edge.
2 Using pliers, grasp the part of the bracket extending over the edge and push
down. The assembly will break along the score line.
3 Use a file to smooth any rough edges which occur along the break.
When installing the solenoid valve assembly with a dual sensor, a CF40 (2-3/4 in.
ConFlat) feedthrough equipped with three pass tubes (two water and one air) and
two coaxial feedthroughs (PN 002-080, refer to
Figure 1-22 on page 1-32 , or PN
206-890-G2, Figure 1-25 on page 1-35 ) is required.
All other shuttered sensors using CF40 (2-3/4 in. ConFlat) feedthroughs require
only a single coaxial feedthrough (PN 750-685-G1, refer to
Figure 1-21 on page
1-31 , or PN 750-685-G2, Figure 1-24 on page 1-34 ).
