initial start-up (no Load)
Before operating the home generator or placing it into
service, inspect the entire installation carefully. Then begin
testing the system without any electrical loads connected,
as follows:
note: 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 secure control panel to
enclosure to expose unit’s circuit breaker.
2. Connect an accurate frequency meter to line side of
generator’s main circuit breaker.
3. Set generator’s main 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.
note: 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. Check generator output at load side of circuit breaker.
Voltage should be 239 - 262 Volts, frequency should
be 62.0 - 62.5 Hz.
note: 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.
iMPortant: 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 control panel into enclosure.
