Attention After Submersion
DO NOT start or operate generator if it has been sub-
merged in water. Have an IASD thoroughly clean, dry,
and inspect generator following any submersion in water.
If the structure (home) has been flooded, it should be
inspected by a certified electrician to verify there will not
be any electrical problems during generator operation or
when utility power is returned.
Corrosion Protection
Regular scheduled maintenance should be conducted to
inspect unit for corrosion. Inspect all metal components
of generator, including base frame, brackets, alternator
can, the entire fuel system (inside and outside of the gen-
erator), and fastener locations. If there is corrosion found
on generator components (e.g. regulator, engine/alterna-
tor mounts, fuel plenum, etc.), replace parts as neces-
sary.
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
Procedure
Remove From Service
If generator cannot be exercised monthly, at a minimum,
and will be out of service longer than 90 days, proceed as
follows to prepare generator for storage:
1.
Start engine and allow it to warm up.
2.
Close fuel shutoff valve in fuel supply line and
allow engine to stop.
3.
Set generator MLCB (generator disconnect) to
OFF (OPEN) once engine has stopped.
4.
Remove 7.5A fuse from generator control panel.
5.
Disconnect battery cables. Remove negative bat-
tery cable first.
6.
Drain oil completely while engine is still warm, and
then fill crankcase with oil. See
.
7.
Attach a tag to engine indicating viscosity and clas-
sification of the new oil in the crankcase.
8.
Remove spark plug(s) and spray a fogging agent
into spark plug(s) threaded openings. Install and
tighten spark plug(s) to specification.
9.
Remove battery and store in a cool, dry place.
10.
Clean and wipe down generator enclosure.
Return to Service
Proceed as follows to return unit to service after storage:
1.
Check tag on engine for oil viscosity and classifica-
tion. Drain and fill with correct oil if necessary.
2.
Verify state of battery. Fill all cells of unsealed bat-
teries to correct level with distilled water.
DO NOT
use tap water. Charge battery to 100% state of
charge. Replace battery if faulty.
3.
Clean and wipe down generator enclosure.
4.
Verify 7.5A fuse is removed from generator control
panel.
5.
Connect battery. Observe battery polarity. Damage
will occur if battery is connected incorrectly. Install
positive battery cable first.
6.
Open fuel shutoff valve.
7.
Insert 7.5 A fuse into generator control panel.
8.
Complete Install Wizard procedure (diagrammed in
generator installation manual).
9.
Press MANUAL button to start unit. Allow unit to
warm up for a few minutes.
10.
Press control panel OFF button to stop unit.
11.
Set generator MLCB (generator disconnect) to ON
(CLOSED).
12.
Press AUTO button on control panel.
The generator is ready for service.
NOTE:
Exercise timer and current date and time must be
reset if a battery has been completely discharged or dis-
connected.
(000238)
Explosion. Batteries emit explosive gases.
Always disconnect negative battery cable
first to avoid spark. Failure to do so could
result in death or serious injury.
WARNING
(000133)
WARNING
Explosion. Batteries emit explosive gases.
Always connect positive battery cable first to
avoid spark. Failure to do so could result in
death or serious injury.
