CrystalSix Operating Manual
3.1 Installation with 1” Bolts
Installation of the solenoid valve assembly for the CrystalSix sensor requires one
1" bolt feedthrough (IPN 750-030-G1, see
Figure 5-1 on page 5-1 ).
Follow these steps:
1 Ensure that the o-ring is in placed on the bolt. Insert the 1" bolt such that the
hexagonal shaped end of the bolt is on the vacuum side of the chamber.
2 Add the Bracket.
3 Add the Washer.
4 Add the Nut.
5 Tighten the feedthrough nut.
6 Add the air fitting to the tube which has the female thread adapter installed.
7 Connect 1/8" diameter tubing from the valve output (A) to the feedthrough
fitting.
CAUTION
Use of more than 80" (2 meters) of 1/8" tubing between
the valve and the bellows may cause switcher failure
because of the time required to bleed out sufficient air
during de-pressurization. If tubing greater than 1/8" is
used, the maximum length must be reduced proportional
to the additional volume.
8 Attach the valve’s supply (normally closed (NC) port) to the 80-90 PSIG
(5.5 bar - 6.2 bar) [550 kPa - 620 kPa] source of air. Verify that the orifice (IPN
059-189) has been installed into this NC valve port. (See Figure 3-1b of
Figure
3-1 on page 3-4 .)
