Cleaning the Sediment Trap
A 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 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 off generator set fuel supply.
3. See Figure 4-7 . Unscrew and remove sediment
trap cap (A).
Figure 4-7. Cleaning the Sediment Trap
4. Use a clean-out tool (not provided) to remove
accumulated moisture and particles from sediment
trap cap and body (B).
5. Wipe inside of each component with a clean, dry,
lint-free cloth.
6. Seal threads of sediment trap cap with appropriate
sealing compound. Install sediment trap cap and
hand-tighten.
7. Tighten sediment trap cap with an appropriately
sized pipe wrench. DO NOT overtighten.
8. Turn on generator set fuel supply. Inspect for leaks
by spraying all connection points with a non-corro-
sive gas leak detection fluid. The solution should
not be blown away or form bubbles.
9. Install intake side panel.
