Initial Start-Up (No Load) - GE HOME GENERATOR SYSTEM 18000 WATT Installation And Start-Up Manual

initial start-up (no Load)

Before operating the generator or placing it into service,
inspect the entire installation carefully. Then begin testing the
system without any electrical loads connected, as follows:
Unit has been set-up for NG operation at the factory. Fuel
conversion, if needed, must be completed prior to performing
these steps. See Fuel Conversion later in this section.
1. Remove four screws that hold circuit breaker cover to
air intake guard.
2. Connect an accurate AC voltmeter and a frequency
meter to line side of generator's circuit breaker.
3. Set generator's circuit breaker to on (closed) position.
4. Install 15 Amp fuse in control panel.
5. Set generator's system switch to auto.
6. Push and hold ManuaL oVer-riDe button on control
panel for about six seconds. Engine will start.

When the generator is started for the very first time, it will
require that air in the gaseous fuel lines be purged. This may
take a few minutes.
7. Listen for unusual noises, vibration or other
indications of abnormal operation. Check for oil leaks
while engine runs.
8. Let engine warm up for about five minutes to allow
internal temperatures to stabilize.
9. No-load voltage should be 239 - 262 Volts, frequency
should be 62.0 - 62.5 Hz.
If either parameter is outside these ranges, perform Engine
Adjustment described later in this section.
10. Check generator output between one generator
connection lug and neutral lug, then between
other generator connection lug and neutral lug.
In both cases, voltage reading should be between
119 and 131 Volts.
DO NOT proceed until you are certain that generator AC
voltage and frequency are correct and within the stated
limits. To obtain the proper generator frequency, see
Engine Adjustment.
11. Push and hold ManuaL oVer-riDe button on
control panel until engine stops.
12. Reinstall circuit breaker cover.
