B. Cover Installation
1. Reverse previous procedures for cover installa-
tion.
NOTE!
When installing the upper screws, at-
tempt to reuse the original threads. The

the threads line up, then begin to turn
the screw clockwise to tighten to 15-18

better system performance, the filter element should be

1. Remove power from the power supply; turn OFF
the gas supply and bleed down the system.
2. Remove the system cover. See "A Cover Re-
moval" in this section.

the filter assembly. Number 1 in the following
illustration.
4. Hold a wrench or similar tool against the locking
ring on the filter assembly fitting, then pull on
the hose to release it. (Numbers 2 and 3 in the
