The remote panel includes a Start/Stop switch, hourmeter, generator run lamp, a fuel prime switch, and a wire harness. Figure 2.2 — Optional Remote Panel (Part Numbers 0F0429 and 0F0430) FUEL RUN PRIME 2.
Section 2 – Operation QUIETPACT 55, 65, and 75 Recreational Vehicle Generators DANGER ! The generator engine releases DEADLY carbon monoxide gas through its exhaust system. This dangerous gas, if breathed in sufficient concentrations, can cause unconsciousness or even death. Never operate the generator set with the vehicle inside any garage or other enclosed area. DO NOT OPERATE THE GENERATOR IF THE EXHAUST SYSTEM IS LEAKING OR HAS BEEN DAMAGED.
Section 2 – Operation QUIETPACT 55, 65, and 75 Recreational Vehicle Generators ◆ 2.7.2 DO NOT OVERLOAD THE GENERATOR Read the rated wattage/amperage capacity of the generator on the generator data decal (see Section 1.1). Applying electrical loads in excess of the unit’s rated capacity will cause the engine/generator to automatically shut down. To avoid overloading, add up the wattage of all connected electrical lighting, appliance, tool and motor loads.
Section 3 – Maintenance QUIETPACT 55, 65, and 75 Recreational Vehicle Generators ◆ 2.8.4 OVERVOLTAGE PROTECTION A solid-state voltage regulator (Figure 2.5) controls the generator’s AC output voltage. This regulator supplies an excitation current to the rotor. By regulating the rotor’s excitation current, the strength of its magnetic field is regulated and, in turn, the voltage delivered to connected electrical loads is controlled. When the AC frequency is 60 Hertz, voltage is regulated at 115 volts.
Section 3 – Maintenance QUIETPACT 55, 65, and 75 Recreational Vehicle Generators 3.2 CHANGING THE ENGINE OIL AND/OR OIL FILTER 9. Start the engine and check for leaks. Figure 3.2 — Engine Oil Filter • Change the engine oil after the first 25 hours of operation (after the 25-hour break-in period, see Section 2.8.5). Thereafter, change the oil every 100 operating hours. Change the oil more frequently if operating consistently under heavy load or at high ambient temperatures.

Clean the area around the base of the spark plug to keep dirt and debris out of the engine.
Section 3 – Maintenance QUIETPACT 55, 65, and 75 Recreational Vehicle Generators 3.7 CLEANING THE GENERATOR Keep the generator set as clean and dry as possible. Protect the unit against excessive dust, dirt, corrosive vapors, road splash, etc. Permitting dirt and moisture to accumulate on generator windings will have an adverse effect on the insulation resistance of those windings.
Section 3 – Maintenance QUIETPACT 55, 65, and 75 Recreational Vehicle Generators 3.9 MAJOR SERVICE MANUAL To obtain a service manual for the generator, contact the nearest Generac Authorized Service Dealer. Make sure to identify the MODEL NUMBER and SERIES. Manuals can be obtained from the internet website (www.generac.com) or a service dealer. 3.10 DRIVE BELT The engine drives the generator rotor by means of a pulley and drive belt arrangement.

Section 6 – Installation QUIETPACT 55, 65, and 75 Recreational Vehicle Generators • If the generator cannot be bolted directly to the supporting frame or support tubing, consider using additional tubing, angle brackets or other supports to give the supporting frame sufficient strength. Figure 6.3 – Typical Generator Restraint ◆ 6.1.
Section 6 – Installation QUIETPACT 55, 65, and 75 Recreational Vehicle Generators • If the compartment is lined with galvanized steel, it may be constructed of any material. Generac recommends that the compartment be constructed of 1/2-inch thick plywood (not strandboard), with the floor made of a double thickness of 1/2-inch plywood with the grain of the wood at cross section for added strength (Figure 6.5).
Section 6 – Installation QUIETPACT 55, 65, and 75 Recreational Vehicle Generators Using a combination of sound insulating materials can often reduce noise more effectively than a single material. For example, a sheet of lead or visco-elastic material, along with a layer of other acoustical material, is more effective than when a single material is used. ◆ 6.2.4 ACOUSTICS For additional noise abatement, the installer may wish to consider the following: • Using special sound insulating materials.

Section 6 – Installation QUIETPACT 55, 65, and 75 Recreational Vehicle Generators Figure 6.12 – LP Gas Carburetion Diagram ◆ 6.5.8 EXCESS FLOW VALVE LP gas tanks should have an excess flow valve, according to NFPA 501C, Paragraph 3-4.4. This valve and the gas lines must be carefully sized so the valve will close when a fuel line is severed or broken. Consult the Natural-LP Gas Association for information and limitations of excess flow valves.
Section 6 – Installation QUIETPACT 55, 65, and 75 Recreational Vehicle Generators ! Never tee the generator engine exhaust pipe into the vehicle engine exhaust piping. This causes excessive back pressure on the generator engine. Also, water from one engine can damage the other engine. ◆ 6.6.1 MUFFLERS AND SPARK ARRESTORS This muffler meets code and standard requirements of the U.S. Forest Service. Use only mufflers and parts approved by Generac.
