B. Filter Element Replacement
The Regulator/Filter Assembly is on the rear panel. For better system performance, the Regulator/Filter Assembly filter
element should be checked per the Maintenance Schedule (Appendix 3), and either cleaned or replaced.
1. Remove power from the power supply; turn off the gas supply and bleed down the system.
2. Unscrew the bowl on the bottom of the Regulator/Filter Assembly. The filter element will be visible and still
attached to the main body of the Regulator/Filter.
3. Grasp the filter element and unscrew it from the Regulator/Filter body. The filter element will come off with a
spool and some additional pieces.
4. Note the correct assembly of the filter/spool then remove the filter from the spool and either clean it or replace
it.
5. The filter element and spool, with the baffle ring in place (teeth facing downward) can be screwed back into the
Regulator body by compressing the spring on the spool. Tighten firmly by hand.
