Section 2 — Post Installation Start-up and Adjustments

Air-cooled Generators

1.	Turn off utility power to the main distribution
	panel in the house. This can be done by switching
	the service main breaker to the off or open posi-
	tion.
2.	Allow the generator to start. Before loading the
	generator, confirm that the No Load Frequency,
	with the roof open and door off, is set to 63-63.5
	Hz. Transfer load to emergency circuits.
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:
	Unit	120 Volts	240 Volts
	7 kW	50.0 amps	25.0 amps
4.	When 3/4 load has been achieved. Connect a fre-
	quency meter to the output lugs of the generator’s
	main line circuit breaker.
5.	The fuel regulator is fitted with one adjustment
	screw. While watching the frequency meter, slowly
	turn the adjustment screw clockwise or counter-
	clockwise 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 (Figure 2.1).

If this procedure or the test equipment is not avail- able, locate the nearest Dealer and they can perform the adjustments.

NOTE:

A service fee may be charged for this adjustment.
