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.
Perform all steps in
2.
Remove intake side panel (see
3.
Turn generator set fuel supply off.
4.
. Unscrew and remove cap (A).
Figure 4-8. Cleaning the Sediment Trap
5.
Use a clean-out tool (not provided) to remove
accumulated moisture and particles from cap and
body (B).
6.
Wipe inside of each component with a clean, dry,
lint-free cloth.
7.
Seal threads of cap with appropriate sealing com-
pound. Install cap and hand-tighten.
8.
Tighten cap with an appropriately sized pipe
wrench. DO NOT overtighten.
9.
Turn generator set fuel supply on. 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.
10.
Install intake side panel.

Generator Set Enable/Disable Procedure
Attention After Submersion
DO NOT start or operate generator set if it has been sub-
merged in water. Have an IASD thoroughly clean, dry,
and inspect generator set following any submersion in
water. If structure (home) has been flooded, it should be
inspected by a certified electrician to verify there will not
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 unit for corrosion. Inspect
all metal components of generator set, including base
frame, brackets, generator housing, entire fuel system
(inside and outside of generator set), and fastener loca-
tions. If corrosion is found on generator set components
(for example: regulator, engine/generator mounts, fuel
plenum, etc.), replace parts as necessary.
Periodically wash and wax enclosure using automotive
type products. Do not spray unit with a hose or power
washer. Use warm, soapy water and a soft cloth. Fre-
quent 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 generator set cannot be exercised monthly, at a mini-
mum, and will be out of service longer than 90 days, pro-
ceed as follows to prepare generator set for storage:
1.
Start engine and allow it to warm up.
2.
Turn off generator set fuel supply and allow engine
to stop.
3.
Once engine has stopped, set MLCB (generator
disconnect) to OFF (OPEN).
4.
Remove 7.5A fuse from generator set control
panel.
5.
Disconnect battery charger AC input T1/T2 cable
(white sleeve) at controller.
6.
Disconnect battery cables. Remove negative bat-
tery cable first, then positive battery cable.
7.
Drain oil completely while engine is still warm, and
then fill crankcase with oil.
8.
Attach a tag to engine indicating viscosity and clas-
sification of new oil in crankcase.
9.
Remove spark plugs using a 5/8 in socket wrench.
Spray a fogging agent into spark plug(s) threaded
openings. Install and tighten spark plug(s) to speci-
fication.
10.
Remove battery and store in a dry place where
temperatures do not drop below freezing.
11.
Clean and wipe down entire generator set.
