Cleaning the Sediment Trap
The sediment trap removes contaminants (moisture and
fine particles) from gaseous fuels before they enter the
fuel regulator. Accumulated moisture and particles must
be emptied from the sediment trap per local codes and
guidelines.
Proceed as follows to clean sediment trap:
1. Remove intake side panel. See Intake Side Panel
Removal.
2. Turn generator fuel supply OFF.
3. See Figure 4-11. Unscrew and remove cap (A).
Figure 4-11. Cleaning the Sediment Trap
4. Use a clean-out tool (not provided) to remove
accumulated moisture and particles from cap and
body (B).
5. Wipe inside of each component with a clean, dry,
lint-free cloth.
6. Seal threads of cap with appropriate sealing com-
pound. Install cap and hand-tighten.
7. Tighten cap with an appropriately sized pipe
wrench. DO NOT overtighten.
8. Turn generator fuel supply ON. Inspect for leaks by
spraying all connection points with a non-corrosive
gas leak detection fluid. Solution should not be
blown away or form bubbles.
9. Install intake side panel.
Post Maintenance Checks
Proceed as follows to perform post maintenance checks:
1. Perform required maintenance procedure(s).
2. Install intake side panel and front panel if removed.
(See Intake Side Panel Removal and Front
Access Panel Removal.)
3. Install 7.5A fuse in control panel.
4. Complete Install Wizard information.
5. Press AUTO button on control panel. Allow unit to
run for one minute with no load (if running during a
utility outage).
6. Set generator MLCB (generator disconnect) to ON
(CLOSED).
