2.5ATTENTION REQUIRED AFTER SUBMERSION, Load

Section 2 – Operation

IMPACT-36 plus II Recreational Vehicle Generator

2.4APPLYING LOADS TO GENERATOR

When applying electrical loads to the generator, observe these guidelines:

•Before applying electrical loads, let the generator stabilize and warm up for a minute or two.

•DO NOT overload the generator.

◆2.4.1 LETTING ENGINE STABILIZE

The generator supplies correctly rated frequency and voltage only at the proper governed speed. Some elec- trical appliances may be extremely sensitive to volt- age and frequency. Incorrect frequencies and/or volt- ages can damage those appliances.

If electrical loads are applied at reduced operating speeds, such loads imposed on the engine when suf- ficient power is not available may shorten engine life. Never turn ON electrical loads until after the genera- tor engine has started and stabilized ON-speed.

2.5ATTENTION REQUIRED AFTER

SUBMERSION

If the motor home generator has been submerged in water, it must NOT be started or operated. Following any submersion in water, have an authorized Generac Service Facility thoroughly clean and dry the generator.

2.6OPERATION IN HIGH GRASS OR

BRUSH

Never operate the generator while the vehicle is parked in high grass, weeds, brush or leaves. Such materials can ignite and burn from the heat of the exhaust system. The generator exhaust system becomes extremely hot during operation and remains hot for a long time after it has shut down.

2.7OPERATING PRECAUTIONS

Never operate the motor home generator set while the vehicle is parked over dry leaves, dry grass or any other combustible substance. The generator’s exhaust system becomes extremely hot and can cause a fire if it is too close to combustible materials.

2.8FUEL REQUIREMENTS (LP UNITS)

These generators are equipped with a liquefied petro- leum (LP) gas fuel system. LP gas is usually supplied as a liquid in pressure tanks.

These generators require a “vapor withdrawal” type fuel system. This type of gaseous fuel system uses the vapors forming above the liquid fuel in the storage tank. Air temperature around the storage tank must be high enough to sustain adequate fuel vaporization. In colder climates, use of an independent heat source may be needed to be sure the fuel sufficiently vapor- izes in the storage tank.

LP gas may consist of propane, butane or a mixture of the two gases. Propane vaporizes at temperatures as low as -20°F (-29°C), but butane returns to its liq- uid state when the temperature drops below about 32°F (0°C). For that reason, a higher ratio of propane is desired in the gas mixture when temperatures drop below freezing.

FUEL CONSUMPTION (IN GALLONS PER HOUR):

	LOAD	LP
	NO	0.20
	HALF	0.41
	FULL	0.77

2.9ENGINE OIL REQUIREMENTS

The recommended oils include the following:

•During summer months: SAE 30. An acceptable substitute is SAE 10W-30.

•During winter months: SAE 5W30. DO NOT USE SAE 10W-40.

Crankcase and oil filter capacity is about 950ml or one (1) quart. Use no special additives. See “Maintenance” section for oil level check and fill pro- cedures.
