DRYER PARTICULATE FILTER
3
The air for the O generator passes through a dryer equipped with a small particulate
3
filter at its inlet, which prevents dust from entering the ozone 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 record 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.
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 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 (Teledyne
API P/N FL-3).
