3. Turn on appliances, lights, pumps, etc., that are on
the emergency circuits in an attempt to fully load the
generator. Be cautious not to overload the generator.
Use the following chart as a guide:
4. When full load has been achieved. Connect a
frequency meter to the output lugs of the generator’s
main line circuit breaker.
5. The fuel regulator is fitted with one (7 kW), or two (12
& 15 kW) adjustment screws. While watching the
frequency meter, slowly turn the adjustment screws
clockwise or counterclockwise one at a time until the
highest frequency is read on the meter. Only limited
adjustment is available because of the set pin. Under
no circumstances should any of the pins be removed
(Figures 1.1 and 1.2).
Figure 1.1 — Dual Fuel Regulators
6. When the highest frequency is reached maximum
power has been set. From this point turn both
adjustment screws 1/4 turn counterclockwise. The
regulator is now set.
Figure 1.2 — Placement of Regulator
7. Turn utility power to the main distribution panel back
on. This can be done by switching the service main
breaker to the on or closed position. Allow the
generator to shut down.
Do not make any unnecessary adjustments.
Factory settings are correct for most
applications. However, when making
adjustments, be careful to avoid overspeeding
the engine.
1.7 RECONFIGURING THEFUEL SYSTEM1.7.1 7 KW, 410CC ENGINE
To reconfigure the fuel system from NG to LP,
follow these steps (Figure 1.3):
NOTE:
The primary regulator for the propane supply is NOT
INCLUDED with the generator. A fuel pressure of 11
to 14 inches of water column (0.4 to 0.5 psi) to the
fuel inlet of the generator MUST BE SUPPLIED.
1. Turn off the main gas supply (if connected).
2. Open the top and remove the front panel.
3. Remove the battery (if installed).
4. Disconnect wire #0 and wire #14 from the gas
solenoid on top of the demand regulator.
5. Remove the carburetor fuel hose from the outlet port
of the demand regulator.
6. Remove the demand regulator by removing the
fastener that retains the regulator mounting bracket.
7. Remove the square headed steel pipe plug from
outlet port #1 and the brass hose barb fitting from
outlet port #2.
8. Refit the brass hose barb fitting to outlet port #1 and
the square headed steel pipe plug to outlet port #2.
