◆2.4.2 ENGINE LUBRICATION

Section 2 – Operation

QUIETPACT 40G Recreational Vehicle Generator

◆2.4.2 ENGINE LUBRICATION

Have the engine crankcase properly serviced with the recommended oil before starting. Refer to Section 1.5.4 (Page 6) and Sections 3.1 and 3.2 (Page 12) 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.

Any attempt to crank or start the engine before◆2.4.3 FUEL SUPPLY DANGER

The generator engine releases 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) nausea, (c) vomiting, (d) twitching muscles, (e) throbbing temples, (f) dizziness, (g) headaches, (h) weakness, and (i) sleepiness. IF YOU EXPERIENCE ANY OF THESE SYMPTOMS, MOVE INTO FRESH AIR IMMEDIATELY. IF SYMP- TOMS PERSIST, GET MEDICAL HELP. Shut down the generator and do not operate it until it has been inspected and repaired.

Never sleep in the vehicle while the genset is

!running unless the vehicle has a working carbon monoxide detector. The exhaust system must be installed in accordance with the genset installa- tion manual. Make sure there is ample fresh air when operating the genset in a confined area.

2.5STARTING THE GENERATOR

NOTE:

Read the vehicle manufacturer’s instructions. The owner/operator should become familiar with the vehicle in which this generator is installed. Differences exist between vehicles. For example, some vehicles may use a transfer switch to isolate dockside power from the generator, while other vehicles may use an isolating receptacle. Some vehicles may be equipped with a DC converter, which allows the generator to power certain DC lighting and other DC loads.

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 10 to 15 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, wait one minute and try again. Holding the switch for longer than 15 seconds can dam- age the starter motor.

4.Let the engine run at no-load for a few minutes to stabilize and warm up.

5.Turn ON electrical loads using the means provided (such as a main circuit breaker or transfer switch).
