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. Disconnect  battery  charger  AC  input  T1/Neutral 
cable (with white sleeve) at controller.
5. Remove 7.5A fuse from generator control panel.
6. Disconnect  battery  cables.  Remove  negative  bat-
tery cable first.
7. Drain oil completely while engine is still warm, and 
then  fill  crankcase  with  oil.  See 
Engine Oil 
Requirements.
8. Attach a tag to engine indicating viscosity and clas-
sification of the new oil in the crankcase.
9. Remove  spark  plug(s)  and  spray  a  fogging  agent 
into  spark  plug(s)  threaded  openings.  Install  and 
tighten spark plug(s) to specification.
10. Remove battery and store in a cool, dry place.
11. 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 cable first.
6. Connect battery charger AC input T1/Neutral cable 
(with white sleeve) at controller.
7. Open fuel shutoff valve.
8. Insert 7.5 A fuse into generator control panel. 
9. Complete Install Wizard procedure (diagrammed in 
generator installation manual).
10. Press  MANUAL  button  to  start  unit. Allow  unit  to 
warm up for a few minutes.
11. Press control panel OFF button to stop unit.
12. Set  MLCB  (generator  disconnect)  to  ON 
(CLOSED).
13. 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.
WARNING
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.
