2. Set the generator's AUTO/OFF/MANUAL switch to the OFF
position.
3. Turn OFF all breakers on the load center of the transfer box (T1
and T2).
4. Turn OFF all loads connected to the transfer switch terminals
T1 and T2.
5. Check the engine crankcase oil level and, if necessary, fill to
the dipstick FULL mark with the recommended oil. Do not fill
above the FULL mark.
6. Check the fuel supply. Gaseous fuel lines must have been
properly purged and leak tested in accordance with applicable
fuel-gas codes. All fuel shutoff valves in the fuel supply lines
must be open.
During initial start up only, the generator may exceed the normal
number of start attempts and experience an "over crank" fault (See
the "Overcrank" section). This is due to accumulated air in the fuel
system during installation. Reset the control board and restart up
to two more times, if necessary. If unit fails to start, contact the
local dealer for assistance.
Never operate the engine with the oil level

below the "Add" mark on the dipstick. Doing
this could damage the engine.
2.3 CHECK TRANSFER SWITCH
OPERATION
Refer to the "Manual Transfer Operation" section, of the owner's
manual for procedures.

DO NOT attempt manual transfer switch oper-
ation until all power voltage supplies to the
transfer switch have been positively turned
off. Failure to turn off all power voltage sup-
plies will result in extremely hazardous and
possibly fatal electrical shock.
2.4

ELECTRICAL CHECKS

Complete electrical checks as follows (voltages and frequencies
will be approximate):
1. Set the generator's main circuit breaker to its OFF (or OPEN)
position.
2. Set the generator's AUTO/OFF/MANUAL switch to the OFF
position.
3. Turn OFF all breakers on the load center of the transfer box (T1
and T2).
4. Turn on the utility power supply to the transfer switch using
the means provided (such as a utility main line circuit break-
er).

The transfer switch is now electrically
"hot." Contact with "hot" parts will result in
extremely hazardous and possibly fatal
electrical shock. Proceed with caution.
Post Installation Start-up and Adjustments
5. Use an accurate AC voltmeter to check utility power source
voltage across transfer switch terminals N1 and N2. Nominal
line-to-line voltage should be 240 volts AC.
6. Check utility power source voltage across terminals N1 and
the transfer switch neutral lug; then across terminal N2 and
neutral. Nominal line-to-neutral voltage should be 120 volts
AC.
7. When certain that utility supply voltage is compatible with
transfer switch and load circuit ratings, turn OFF the utility
power supply to the transfer switch.
8. On the generator panel, set the Auto/Off/ Manual switch to
MANUAL. The engine should crank and start.
9. Let the engine warm up for about five minutes to allow inter-
nal temperatures to stabilize. Then, set the generator's main
circuit breaker to its ON (or closed) position.

Proceed with caution! Generator power volt-
age is now supplied to the transfer switch.
Contact with live transfer switch parts will
result in dangerous and possibly fatal electri-
cal shock.
10. Connect an accurate AC voltmeter and a frequency meter
across transfer switch terminal lugs E1 and E2. Voltage
should be 240-244 at a frequency of 59.5-60.5 Hertz.
11. Connect the AC voltmeter test leads across terminal lugs E1
and neutral; then across E2 and neutral. In both cases, voltage
reading should be 120-122 volts AC.
12. Set the generator's main circuit breaker to its OFF (or OPEN)
position.
13. Set the generator's AUTO/OFF/MANUAL switch to OFF. The
engine should shut down.
It is important not to proceed until certain that generator AC
voltage and frequency are correct and within the stated limits.
2.5

GENERATOR TESTS UNDER LOAD

To test the generator set with electrical loads applied, proceed as
follows:
1. Set generator's main circuit breaker to its OFF (or OPEN) posi-
tion.
2. Turn OFF all breakers on the load center of the transfer box (T1
and T2).
3. Set the generator's AUTO/OFF/MANUAL switch to OFF.
4. Turn OFF the utility power supply to the transfer switch,
using the means provided (such as a utility main line circuit
breaker).

Do not attempt manual transfer switch opera-
tion until all power voltage supplies to the
transfer switch have been positively turned
off. Failure to turn off all power voltage sup-
plies will result in extremely hazardous and
possibly fatal electrical shock.
