Owner’s Manual for PWRgenerator Air-Cooled Generators 27
Always recycle batteries in accordance with local laws
and regulations. Contact your local solid waste collection
site or recycling facility to obtain information on local
recycling processes. For more information on battery
recycling, visit the Battery Council International website
at:
http://batterycouncil.org .
Strictly observe the following precautions when working
on batteries:
•
Remove 7.5A fuse from generator control panel.
•
Disconnect battery charger as directed in Battery
Maintenance .
•
Use tools with insulated handles.
•
Wear rubber gloves and boots.
•
Do not place tools or metallic objects on top of bat-
tery.
•
Set generator MLCB (generator disconnect) to
OFF (OPEN) to prevent REbus voltage from CES
powering battery charger in DC converter within
the generator.
•
Wear full eye protection and protective clothing.
•
If electrolyte contacts skin, wash it off immediately
with water.
•
If electrolyte contacts eyes, flush thoroughly with
water immediately and seek medical attention.
•
Wash down spilled electrolyte with an acid neutral-
izing agent. A common practice is to use a solution
of 1 lb (454 g) bicarbonate of soda to 1 gal (3.8 L)
of water. Add bicarbonate of soda solution until evi-
dence of reaction (foaming) has ceased. Flush
resulting liquid with water and dry area completely.
•
DO NOT smoke near battery.
•
DO NOT cause flame or spark in battery area.
•
Discharge static electricity from the body before
touching battery by first touching a grounded metal
surface.
Battery should be regularly inspected per Service
Schedule . Contact an IASD for assistance if necessary.
Inspecting the Battery
Proceed as follows to inspect battery:
1. Press OFF button to shut down generator, then lift
lid and remove front panel.
2. Set generator MLCB (generator disconnect) to
OFF (OPEN).
3. Remove 7.5A fuse from control panel.
4. Remove intake side panel. (See Intake Side Panel
Removal .)
5. See Figure 4-4 . Inspect battery posts and cables
for tightness and corrosion. Tighten and clean as
necessary.
Figure 4-4. Battery Cables
6. Unsealed batteries only: Completely disconnect
battery. 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 ver-
ify state of charge and condition.
7. Connect battery cables, install intake side panel,
and install 7.5 A fuse when inspection is complete.
8. Press AUTO button on controller.
9. Set generator MLCB (generator disconnect) to ON
(CLOSED).
10. 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 Intake Side Panel
Removal .
2. Turn generator fuel supply OFF.

Electrical shock. Disconnect battery ground
terminal before working on battery or battery
wires. Failure to do so could result in death
or serious injury.
(000138a)
WARNING
Risk of burns. Batteries contain sulfuric acid and can
cause severe chemical burns. Wear protective gear
when working with batteries. Failure to do so could
result in death or serious injury.
WARNING

Environmental Hazard. Always recycle batteries at an
official recycling center in accordance with all local
laws and regulations. Failure to do so could result in
environmental damage, death, or serious injury.
