Teledyne 9110T Changing the O3 Dryer Particulate Filter, Ensure to use proper wrenches

Model 9110T NOx Analyzer Instrument Maintenance

11.3.2. CHANGING THE O3 DRYER PARTICULATE FILTER

The air for the O3 generator passes through a Perma Pure© dryer, which is equipped with a small particulate filter at its inlet. This filter prevents dust from entering the Perma Pure© dryer and degrading the dryer’s performance over time. Change the filter according to the service interval in Table 11-1 as follows:

1.Before starting the procedure, check and write down the average RCEL pressure and the OZONE FLOW values.

2.Turn off the analyzer, unplug the power cord and remove the cover.

3.Unscrew the nut around the port of the filter using two 5/8” wrenches.

ATTENTION	COULD DAMAGE INSTRUMENT AND VOID WARRANTY
	Ensure to use proper wrenches.
	Hold the main dryer fitting with a 5/8” wrench to ensure that it does not
	turn against the Perma Pure© dryer.
	Performing this procedure improperly or with incorrect tools creates a
	risk of causing a significant leak.
	4. Take off the old filter element and replace it with a suitable equivalent (TAI P/N FL-
	3).
