and four 1/2 inch X 1-3/4 inch stainless steel bolts: please see Figure 3.1.
Probe head removal

Open the conditioning assembly door and locate the dilution probe head. Carefully cut and
remove the shipping tie wrap from the probe head and support bracket.

Note the placement of all five (5) Teflon
®
tubes connected to the probe head. Loosen each of
the Teflon
®
tube connection fittings and remove the tubes.

Disconnect the cartridge heater and the RTD from the probe box wiring.
D)
Loosen the probe head securing wing nut, located underneath the support bracket.

Remove the probe head from the bracket and place in a safe, clean area during probe barrel

Probe barrel installation
A)
Inspect the probe barrel assembly for proper flange spacing and orientation (factory set):
please see Figure 3.3 on the following page.
B)
Install the probe flange gasket (factory supplied) over the process end of the probe barrel, for
sealing process gases from the conditioning assembly enclosure.
C)
Insert the probe barrel assembly through the flange porthole, in the back of the conditioning
assembly, with the bend downward. Align the three-hole probe mounting flange and flange
gasket to the three-hole pattern of the conditioning assembly flange porthole.
D)
Insert the three (3) supplied 1/4-20 X 1-3/4 inch bolts through the probe mounting flange into
the threaded holes, and tighten.
E)
Coat the polished probe tip surface with a liberal amount of silicone-based high vacuum
grease. This allows a proper o-ring seal of the probe head.
