6.
Unsealed batteries only: Completely dis-
connect battery, removing negative battery
cable first. Check battery fluid level and, if
necessary, fill with distilled water only. DO
NOT use tap water. Have an IASD or a
qualified service technician verify state of
charge and condition.
7.
Connect positive battery cable, then nega-
tive battery cable.
8.
Connect battery charger cable.
9.
Install intake side panel, and install 7.5 A
fuse.
10.
Press AUTO button on controller.
11.
Install front panel and close generator lid.

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 sediment trap:
1.
Remove intake side panel. See
Side Panel Removal.
2.
Turn generator fuel supply OFF.
3.
See Figure 4-11. Unscrew and remove cap
(A).
Figure 4-11. Cleaning the Sediment Trap
4.
Use a clean-out tool (not provided) to
remove accumulated moisture and parti-
cles from cap and body (B).
5.
Wipe inside of each component with a
clean, dry, lint-free cloth.

6.
Seal threads of cap with appropriate seal-
ing compound. Install cap and hand-
tighten.
7.
Tighten cap with an appropriately sized
pipe wrench. DO NOT overtighten.
8.
Turn generator fuel supply ON. Inspect for
leaks by spraying all connection points
with a non-corrosive gas leak detection
fluid. Solution should not be blown away
or form bubbles.

9.
Install intake side panel.

Post Maintenance Checks

Proceed as follows to perform post mainte-
nance checks:
1.
Perform required maintenance proce-
dure(s).
2.
Install intake side panel and front panel if
removed. (See
and
Front Access Panel
3.
Install 7.5A fuse in control panel.
4.
Complete Install Wizard information.
5.
Press AUTO button on control panel.
Allow unit to run for one minute with no
load (if running during a utility outage).
6.
Set generator MLCB (generator discon-
nect) to ON (CLOSED).
7.
Set utility MLCB to 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

Intake
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.
All products are factory-tested before ship-
ping to verify the performance and integrity of
B
the fuel system. However, it is important to
perform a final fuel system leak test before
starting the generator. The entire fuel system
should be tested from supply to regulator.
A
See Figure
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 during normally-scheduled mainte-
nance.
