32 Owner’s Manual for 60 Hz Air-Cooled Generators
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 cle
an sediment trap:
1. Rem
ove intake side panel. See Intake Side Panel
Removal.
2. T
urn generator fuel supply OFF.
3. See Figure 4-10. Unscrew and remove cap (A).

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. Sea
l threads of cap with appropriate sealing com-
pound. Install cap and hand-tighten.
7. T
ighten cap with an appropriately sized pipe
wrench. DO NOT overtighten.
8. T
urn generator fuel supply ON. Inspect for leaks by
spraying all connection points with a non-corrosive
gas leak detection fluid. The solution should not be
blown away or form bubbles.
9. Install intake side panel.
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 W
izard information.
5. Pr
ess AUTO button on control panel. Allow unit to
run for one minute with no load (if running during a
utility outage).
6. Set
MLCB (generator disconnect) on generator to
ON (CLOSED).
7. T
urn main utility disconnect ON (CLOSED).
The system is now in AUTO.
NOTE: If
correct utility is present at this time, generator
will perform its usual shutdown process.
Performing Fuel System Leak Test
All products are factory-tested before shipping to verify
the performance and integrity of the fuel system. How-
ever, it is important to perform a final fuel system leak test
bef
ore starting the generator. The entire fuel system
should be tested from supply to regulator.
See Figure 4-11. Perform a final fuel system leak test
after generator installation. The
test will identify possible
leaks at all connection points (A).
It is best practice to perform a fuel system leak test
du
ring normally-scheduled maintenance.
Figure 4-11. Connection Points to Leak Check
Inspect for leaks by spraying all connection points with a
no
n-corrosive gas leak detection fluid. The solution
should not be blown away or form bubbles.

DANGER
Explosion and fire. Fuel and vapors are extremely
flammable and explosive. No leakage of fuel is
permitted. Keep fire and spark away. Failure to do
so will result in death or serious injury.
