Teledyne 200A 8.5 Replacing the IZS Zero Air Scrubber

Teledyne API Model 200A NOX Analyzer Instruction Manual, 02246, Rev. G, DCN 5247

NOTE

If the instrument is to be turned off for more than 8 hours, the

perm tube must be removed from the IZS oven. Even at room

temperature the perm tube continues to release NO2. Concentrations

can build up to very high levels inside the instrument causing

contamination and high background readings.

8.5 Replacing the IZS Zero Air Scrubber

The IZS zero air scrubber is located on the rear panel of the instrument. Refer to Table 8-8-1 for

recommended replacement interval. The entire cartridge can be replaced, or just the charcoal and

Purafil inside the cartridge. To replace the scrubber materials:

1. Disconnect the scrubber from the rear panel pneumatic fitting and remove from the hold

down clip. While removing the cartridge, check the DFU filter for contamination and dirt,

replace if necessary.

2. Unscrew the top, remove the felt pad and empty the contents.

3. Inspect the upper and lower felt pads for signs of plugging, replace if necessary.

4. Replace with 50% Purafil(upstream) and 50% charcoal (downstream).

5. Re-install felt pad, screen and re-tighten cap. Make sure the o-ring in the cap is in good

shape and squarely seated.

6. Leak check the assembly, then re-attach scrubber to fitting and clip on rear panel.
