Section 2 – Operation
PRIMEPACT 50 and 70 (50Hz) Recreational Vehicle Generators
2.4BEFORE STARTING THE ENGINE
NOTE:
Instructions and information in this manual assume the generator has been properly installed, connected, serviced, tested and adjusted by a qualified installation technician or installation contractor.
◆2.4.1 INSTALLATION
Generator installation must have been properly com- pleted so it complies with all applicable codes, stan- dards and regulations and with the manufacturer's recommendations.
◆2.4.2 ENGINE LUBRICATION
Have the engine crankcase properly serviced with the recommended oil before starting. Refer to Section 1.6.3 (Page 6) and Sections 3.1 and 3.2 (Page 11) for oil ser- vicing procedures and recommendations.
Any attempt to crank or start the engine before you have properly serviced it with the recom- mended oil may result in an engine failure.
◆2.4.3 FUEL SUPPLY
The engine must have an adequate supply of proper fuel to operate. Before starting it, check that sufficient fuel is available.
NOTE:
Depending on the installation, the generator may have either a separate fuel tank, or it may “share” the vehicle engine’s fuel tank.
◆2.4.4 COOLING AND VENTILATING AIR
Air inlet and outlet openings in the generator com- partment must be open and unobstructed for contin- ued proper operation. Without sufficient cooling and ventilating airflow, the engine/generator quickly over- heats, which causes it to shut down and may damage the generator.
◆2.4.5 ENGINE EXHAUST GAS
Before starting the generator engine, you should be sure there is no way for exhaust gases to enter the vehicle interior and endanger people or animals. Close windows, doors and other openings in the vehi- cle that, if open, might permit exhaust gases to enter the vehicle.
The generator engine gives off DEADLY carbon monoxide gas through its exhaust system. This dangerous gas, if breathed in sufficient concen- trations, 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. SYMPTOMS OF CARBON MONOX- IDE POISONING ARE (a) inability to think coher- ently; (b) vomiting; (c) twitching muscles; (d) throbbing temples; (e) dizziness; (f) headaches;
(g)weakness; and (h) sleepiness. IF YOU FEEL ANY OF THESE SYMPTOMS, MOVE INTO FRESH AIR IMMEDIATELY. IF SYMPTOMS PERSIST, GET MEDICAL HELP.
2.5STARTING THE GENERATOR
To start the generator from either the generator con- trol panel or from the optional remote panel, proceed as follows:
1.Turn OFF electrical loads using the means pro- vided in your vehicle (such as a main line circuit breaker or transfer switch).
NOTE:
If starting from the generator control panel, turn OFF loads by setting the generator’s main circuit breaker to the OFF (or open) position. If starting from a remote panel, turn OFF loads using the means provided in the vehicle (such as a main cir- cuit breaker). Electrical load circuits will be turned ON after the generator has started, stabi- lized and warmed up.
2.If you have not started the engine in more than two weeks, press the Fuel Pump Primer switch and hold it for about five seconds to prime the fuel system. However, if the engine is warm, skip Step 2.
3.Hold the engine Start/Stop switch in the START position to crank the engine. Release the switch when the engine starts.
If the engine does not start after it has been cranking for 15 seconds, release the Start/Stop switch and try again. Holding the switch for longer than 15 seconds can damage the starter motor.
4.Let the engine run at
5.Turn ON electrical loads using the means provided (such as a main circuit breaker or transfer switch).
