Maintenance
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 the sediment trap:
1. Perform all steps in
Disable
Procedure.
2. Remove the intake side panel (see
Intake Side
Panel).
3. Turn the generator set fuel supply off.
4. See
Figure
4-8. Unscrew and remove the cap (A).
Figure 4-8. Cleaning the Sediment Trap
5. Use a clean-out tool (not provided) to remove
accumulated moisture and particles from the cap
and body (B).
6. Wipe the inside of each component with a clean,
dry, lint-free cloth.
7. Seal the threads of the cap with appropriate
sealing compound. Install the cap and hand-
tighten.
8. Tighten the cap with an appropriately sized pipe
wrench. DO NOT overtighten.
9. Turn the generator set fuel supply on. Check 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.
10. Install the intake side panel.
11. Perform "To turn the generator set back ON" in

Procedure.
Attention After Submersion
DO NOT start or operate the generator set if it has been
submerged in water. Have an IASD thoroughly clean, dry,
and inspect the generator set following any submersion
in water. If the structure (home) has been flooded, it
should be inspected by a certified electrician to verify
there won't be any electrical problems during generator
set operation or when mains power is returned.
Corrosion Protection
Regular scheduled maintenance should be conducted to
perform a visual inspection of the unit for corrosion.
Inspect all metal components of the generator set,
including the base frame, brackets, generator housing,
the entire fuel system (inside and outside of the
generator set), and fastener locations. If there is
corrosion found on generator set components (for
example:
regulator,
engine/generator
plenum, etc.), replace parts as necessary.
Periodically wash and wax the enclosure using
automotive type products. Do not spray the unit with a
hose or power washer. Use warm, soapy water and a soft
cloth. Frequent washing is recommended in salt water/
coastal areas. Spray engine linkages with a light oil such
as WD-40.
Remove From, and Return To
Service
Remove From Service
If the generator set cannot be exercised monthly, at a
minimum, and will be out of service longer than 90 days,
proceed as follows to prepare the generator set for
storage:
1. Start the engine and let it warm up.
2. Tun off generator set fuel supply and allow the
engine to stop.
3. Once the engine has stopped, set the MLCB
(generator disconnect) to OFF (OPEN).
4. Remove the 7.5A fuse from the generator set
control panel.
5. Disconnect battery charger AC input T1/T2 cable
(white sleeve) at controller.
6. Disconnect the battery cables. Remove the
negative cable first.
Disconnect the negative battery cable,
then the positive battery cable, when
working on unit.
7. Drain the oil completely while the engine is still
warm, and then refill the crankcase with oil.
