Ensure that all gas line shutoff valves are OPEN and that
adequate fuel pressure is available whenever automatic
operation is desired.
INITIAL START -UP
Begin testing the system without any electrical loads
connected, as follows:
1.
Set the AUTO/OFF/MANUAL switch to OFF.
2.
Set the generator's main circuit breaker to its OFF
(open) position.
3.
Install the 15 Amp fuse in the control panel.
4.
Set the AUTO/OFF/MANUAL switch to MANUAL.
NOTE: When the Home Generator System 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.
5.
Use short starting cycles (15 sec. per min.) to reduce
heat in the starter.
6.
Repeat process until lines are purged of air and engine
starts.
7.
Listen for unusual noises, vibration or other indications
of abnormal operation. Check for oil leaks, evidence of
overheating etc. while the unit runs.
Electrical Checks
With the AUTO/OFF/MANUAL switch set to OFF:
1.
Turn ON the main distribution panel circuit breaker
that supplies utility power to the Automatic Transfer
Switch.
WARNING
! The Automatic Transfer Switch is
now electrically "HOT." Contact with "HOT" parts
will result in extremely hazardous and possibly fatal
electrical shock. Proceed with caution.
2.
Use an accurate AC voltmeter to check utility power
voltage across "UTILITY CONNECTION" lugs in the
Automatic Transfer Switch (see Interconnection
Diagram on page 12). Nominal line-to-line voltage
should be 240 Volts.
3.
Check utility power between one of the UTILITY
CONNECTION lugs and the neutral lug, then between
the other UTILITY CONNECTION lugs and the
neutral lug. Nominal line-to-neutral voltage should be
120 Volts.

(NO LOAD)
4.
When certain that utility voltage is as specified above,
turn OFF the main distribution panel circuit breaker
that supplies utility power to the Automatic Transfer
Switch.
5.
Set the generator's main circuit breaker to the OFF
position. Initial tests will be conducted at "no-load"
condition.
6.
Set the AUTO/OFF/MANUAL switch to MANUAL.
The engine should crank and start.
7.
Let the engine warm up for about five minutes to allow
internal temperatures to stabilize.Then, set the
generator's main circuit breaker to its ON (or closed)
position.
WARNING!
output voltage is now supplied to the Automatic
Transfer Switch. Contact with "HOT" Automatic
Transfer Switch parts will result in dangerous and
possibly fatal electrical shock.
8.
Connect an accurate AC voltmeter and a frequency
meter to check generator output across
"GENERATOR CONNECTION" lugs in the Automatic
Transfer Switch (see Interconnection Diagram on
page 12).Voltage should be 239-250 Volts, frequency
should be 62.0 - 62.5 Hz.
NOTE: If either parameter is outside these ranges,
perform the Engine Adjustments described on page 18.
9.
Check generator output between one of the
GENERATOR CONNECTION lugs and the neutral
lug, then between the other GENERATOR
CONNECTION lug and the neutral lug. In both cases,
voltage reading should be between 121-126 Volts.
10. Set the generator's main circuit breaker to OFF. Let
the engine run at "no-load" for a few minutes to
stabilize internal engine/generator temperatures.
11. Set the AUTO/OFF/MANUAL switch to OFF. Engine
should stop.
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 Adjustments on page 18.
