Installation and Start Up
| 3-9
6. Connect clean dry instrument air supply to the 1/4-inch bulkhead
on the right-hand side of the cabinet. If air supply quality is in ques-
tion, connect through two air/oil separators. Back out the air regulator
screw so that air lines on the analyzer are not pressurized.
7. Remove the screws from the cell oven cover plate at the top of the
oven enclosure. Set aside the four screws. The cover plate must be
loosened, but may not have to be removed. The screws must be rein-
stalled and tightened after probe installation.
8. Prepare the probe. The probe tube is 1/2-inch diameter, 316 stainless
steel tubing. The probe supplied is ~910 mm (36 inches) long. Cut
the probe to a length that results in the probe’s end extending into the
pipe 1/4 to 1/2 of its diameter.
Installing the Probe
Refer to Figures 3-2a fand 3-2b or location of all inlet, valve and vent
locations.
The probe enters the oven through a Conax gland with a Teflon ferrule
which uses a nut to seal the probe. The nut can be tightened or loosened
to slide the probe, pull it out or insert another probe for service or mainte-
nance.
1. Install the probe into the 1/2-inch tube fitting on the sample inlet ball
valve (FV1) using the supplied stainless steel ferrule. Make sure the
fitting is tight and leak free.
- Make sure the flange fitting components (nut, SST ferrule, and Tef-
lon® seal) are loosely installed on the flange fitting.
- Verify that the sample inlet ball valve (FV1) is closed.
- Scribe a mark on the probe just under the ball valve to aid in orient-
ing the probe correctly.
All personnel in the immediate area MUST wear fresh-air breathing
apparatus for the remaining installation steps. Do not remove breath-
ing apparatus until installation is complete and all fittings have been
checked for toxic gas leaks.
