Section 5: Maintenance
waRNING
The maintenance and repair of pressure equipment must only be performed by
trained personnel.
Since every application exists under different conditions, the user is responsible for
establishing a maintenance program based on their application until enough data is collected
to set up a schedule . Since the preconditioning filters can collect liquids, they should be
checked frequently to ensure proper performance .
1 . Visual check for damages (i .e . tubing, electrical components and cables) .
2 . Check filters for liquids and particle build up (i .e . differential pressure) .
3 . Check for leaks .
A periodic calibration of the feedback pressure transducer is recommended .
5.1
Filter Maintenance
Filter parts are subject to normal wear and must be inspected periodically and replaced
as necessary . The frequency of inspection and replacement depends upon the severity of
service conditions and upon applicable codes and government regulations .
To ensure a tight seal, check the condition of the O-ring and lubricate it with Multi-Purpose
Polytetrafluoroethylene (PTFE) lubricant whenever disassembling and assembling the filter .
The upper seat is lightly pressed into the filter head . To replace the upper seat, it may be
necessary to remove the 1/4 inch / 6 .35 mm pipe plug and push the upper seat out of the
filter head . (Refer to Figure 5 for a cross-sectional view of filter .)
To Replace C195-X Filter cartridge
1 . Close the upstream and downstream shutoff valves .
2 . Bleed off the pressure .
3 . Open the drain valve and drain the moisture from the filter body .
4 . Unscrew the filter body from the filter head . Inspect the O-ring and replace if damaged .
5 . Remove the filter element .
6 . Lubricate the O-ring with Multi-Purpose PTFE lubricant and reassemble the new
filter element .
7 . Slowly reapply pressure and check for leaks .
