28 Owner’s Manual for Australian 3-Phase 50 Hz Air-Cooled Generator Sets
Post Maintenance Checks
Proceed as follows to complete post maintenance
checks:
1. Perform required maintenance procedure(s).
2. Install intake side panel and front panel if removed.
(See Intake Side Panel Removal and Front
Access Panel Removal.)
3. Install 7.5A fuse in the 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 set MLCB (generator set disconnect)
to ON (CLOSED).
7. Set mains MLCB to ON (CLOSED).
System is now in automatic mode.
NOTE: If correct mains power is present at this time,
generator set will perform its usual shutdown process.
Performing Leak Test
All products are factory-tested before shipping to verify
performance and integrity of the fuel system. However, it
is important to perform a final fuel system leak test before
starting the generator set. The entire fuel system should
be tested from supply to regulator.
See Figure 4-8. Perform a final fuel system leak test
after generator set installation. The test will identify possi-
ble leaks at all connection points (A).
It is best practice to perform a fuel system leak test
during normally-scheduled maintenance.
Figure 4-8. Connection Points to Leak Check
Inspect 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.
Attention After Submersion
DO NOT start or operate generator set if it has been sub-
merged in water. Have an IASD thoroughly clean, dry,
and inspect generator set following any submersion in
water. If structure (home) has been flooded, it should be
inspected by a certified electrician to verify there will not
be any electrical problems during generator set operation
or when mains power is returned.
Corrosion Protection
Regular scheduled maintenance should be conducted to
perform an inspection of the unit for corrosion. Inspect all
metal components of generator set, including base
frame, brackets, alternator can, the entire fuel system
(inside and outside of generator set), and fastener loca-
tions. If there is corrosion found on generator set compo-
nents (e.g. regulator, engine/alternator mounts, fuel
plenum, etc.), replace parts as necessary.
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.

DANGER
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.
