Cleaning The Sediment Trap; Attention After Submersion; Corrosion Protection; Remove From, And Return To Service Procedure - Generac Power Systems 8 kVA Owner's Manual

•
DO NOT smoke when near the battery.
•
DO NOT cause flame or spark in the battery area.
•
Discharge static electricity from the body before
touching the battery by first touching a grounded
metal surface.

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

Attention After Submersion

DO NOT start or operate the generator if it has been
submerged in water. Have an IASD thoroughly clean, dry,
and inspect the generator 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 operation or
when utility 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, including
the base frame, brackets, alternator can, the entire fuel
system (inside and outside of the generator), and
fastener locations. If there is corrosion found on
generator components (e.g. regulator, engine/alternator
mounts, fuel plenum, etc.), replace parts as necessary.
Periodically wash and wax the enclosure using
automotive type products. Do not spray the unit with a
Intake Side
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 Procedure
B

Remove From Service

If the generator cannot be exercised monthly, at a
minimum, and will be out of service longer than 90 days,
proceed as follows to prepare the generator for storage:
A
1. Start the engine and let it warm up.
2. Close the fuel shutoff valve in the fuel supply line
001821
and allow the engine to stop.
3. Once the engine has stopped, set the generator
MLCB (generator disconnect) to OFF (OPEN).
4. Turn off the utility power to the transfer switch.
5. See
T1/T2 (has white sleeve) at controller.
6. Remove the 7.5 amp fuse from the generator's
control panel.
7. Disconnect the battery cables. Remove the
negative cable first.
8. Drain the oil completely while the engine is still
warm, and then refill the crankcase with oil.
9. Attach a tag to the engine indicating the viscosity
and classification of the new oil in the crankcase.
10. Remove the spark plug(s) and spray a fogging
agent into the spark plug(s) threaded openings.
Reinstall and
specification.
