Cleaning The Fid Jet - ABB PGC2000 Operation And Service Manual

2. Route the wiring up through the top of the detector housing .
Steps 3 through 6 are required only for Temperature Programmed analyzers.
3. Slide the housing down over the insulation and detector body onto the base. The housing must
slide over the circular base and rest on the mounting bracket.
4. Bend the capillary tubing back into place, then route the wiring to the back of the detector
housing and install insulation into the housing.
5. Install the detector cover by channeling the cover slot through the machined groove in the
detector body, while sliding the cover into place. Note that the wiring exits through the slot in the
cover, and that the capillary tubing exits the can through the sheared edge of the top cover.
6. Rotate the detector cover latch clockwise until is secured by the detector. Note the small slot in
the latch also fits into the same machined groove the cover fits.
7. Install the breather as explained in "Replacing the Breather."
8. Using the previously installed temporary labels, connect the capillary tubes to their respective
unions.
9. Remove the temporary labels.
10. Install cable ties to secure the detector wiring.
11. Install the red coaxial cable to the connector on top of the detector.
12. Close and secure the isothermal oven door.

Cleaning the FID Jet

Steps 1 and 2 are required only for Temperature Programmed analyzers.
1. Remove the three screws securing the detector can assembly, using a 9/64-inch Allen wrench or
ball driver.
2. Extract the can from the isothermal oven.
3. CENELEC and CSA flame ionization detectors are identified by the presence of three packing
adapter nuts (5/8-inch, 1/2-inch and 7/16-inch). Other models contain only two packing adapter
nuts (5/8-inch and 1/2-inch).
4. On CENELEC AND CSA models, loosen the 7/16-inch packing adapter nut using a 7/16-inch
open-end wrench, backed up with a 1/2-inch open-end wrench on the 1/2-inch packing adapter
nut. Continue to loosen by hand until disconnected.
5. For all models, loosen the 1/2-inch packing adapter nut using a 1/2-inch open-end wrench with a
5/8-inch open-end back-up wrench. Continue to loosen by hand until disconnected.
6. Withdraw the column and associated ferrules and adapters from the detector.
7. Loosen the 5/8-inch adapter fitting from the bottom of the detector.
