Front Load Single and Dual Sensors Operating Manual
INFICON CF40 (2-3/4 in. ConFlat) feedthroughs with air lines are equipped with a
fitting adapter (PN 007-133). This adapter provides an easy way to attach
a quick disconnect fitting (included with the 750-420-G1 Solenoid Valve)
to the feedthrough air line.
Follow the steps below:
1 Install the Feedthrough.
2 Add the valve bracket (modified) to the desired location (shown in Figure 3-3
on page 3-6) using two of the 6.35 mm (1/4 in.) clamp bolts located on the
flange.
3 Tighten the flange bolts.
4 Remove the quick disconnect air fitting from the exhaust port of the
solenoid valve and thread it into the fitting adapter (PN 007-133)
installed on the feedthrough air line.
5 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 4 (see section 3.4, Pneumatic
Connections, on page 3-4).
6 Attach the P port of the solenoid valve to a source of air. The air supply range
is 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.
7 Make electrical connections to the solenoid valve (see section 3.5, Electrical
Connections, on page 3-4)
