O 3 Generator Replacement; Sample And Ozone Dryer Replacement - Teledyne T200 User Manual

O GENERATOR REPLACEMENT
3
The ozone generator is a black, brick-shaped device with a printed circuit board attached
to its rear and two tubes extending out the right side in the front of the analyzer (see Figure
2-3). The board has a red LED that, when lit, indicates ozone is being generated. To replace
the ozone generator:
1. Turn off the analyzer power; remove the power cord and the analyzer cover.
2. Disconnect the 1/8" black tube from the ozone cleanser and the ¼" clear tube from the
plastic extension tube at the brass fitting nearest to the ozone generator.
3. Unplug the electrical connection on the rear side of the brick.
4. Unscrew the two mounting screws that attach the ozone generator to the chassis and
take out the entire assembly.
5. If you received a complete replacement generator with circuit board and mounting
bracket attached, simply reverse the above steps to replace the current generator.

SAMPLE AND OZONE DRYER REPLACEMENT

An optional dryer is available for the sample stream, and a combined dryer for both gas
streams can also be purchased. To change one or both of these dryers:
1. Turn off power to the analyzer and pump, and remove the power cord and the analyzer
cover.
2. Locate the dryer(s), and gently disconnect all tubing that extends out of the dryer
assembly.
3. Make note of the dryer's orientation on the bracket in order to correctly position the
replacement dryer.
4. Cut the tie wraps that hold the dryer to the mounting bracket and take out the old dryer.
•
5. Attach the replacement dryer to the mounting bracket in the same orientation as the old
dryer.
6. Fix the dryer to the bracket using new tie wraps.
