Section 2 – Operation

IMPACT-36 plus II Recreational Vehicle Generator

2.1.4 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 air flow, the engine-generator quickly over- heats, which causes it to automatically shutdown. Overheating could also damage the unit or the vehicle.

2.1.5 ENGINE EXHAUST GAS

Before starting the generator engine, be sure there is no way for exhaust gases to enter the vehicle interior and endangering people or animals. Close windows, doors and other openings in the vehicle that, if open, might permit exhaust gases to enter the vehicle.

◆2.1.5 ENGINE EXHAUST GAS2.2STARTING THE GENERATOR 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 EXPERIENCING 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.

2.3STOPPING THE GENERATORManual background DANGER

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.

2.2STARTING THE GENERATOR

IMPORTANT: READ THE VEHICLE MANUFACTUR- ER’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 TRANS- FER SWITCH TO ISOLATE DOCKSIDE POWER FROM THE GENERATOR, WHILE OTHER VEHI- CLES 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 crank and start the generator engine, proceed as follows:

1.Turn OFF electrical loads, using whatever means provided in the vehicle (such as a main line cir- cuit breaker or transfer switch).

NOTE:

If the engine is started with the start/stop switch on the generator control panel, turn OFF loads by setting the panel’s main breaker to its “OFF” or “OPEN” position. Electrical load circuits may be turned ON after the generator has started, stabi- lized and warmed up.

NOTE:

On gas units, use of the fuel primer is needed only during the initial startup, after the unit has not been used for an extended period of time (two weeks) or the fuel line has been disconnected. The primer is used to prime the fuel pump and carbu- retor.

2.To crank and start the engine, hold the start/stop switch at START. 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 may damage the starter motor.

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

4.Turn ON electrical loads, using whatever means provided (such as a main circuit breaker or transfer switch).

NOTE:

If starting a warm generator engine, press the start switch only slightly to engage the ignition system. However, press and hold the starter switch for a minimum of two (2) seconds to energize the field boost system. If starting the engine without ener- gizing the field boost system, the generator pro- duces no output.

2.3STOPPING THE GENERATOR

1.Turn OFF all electrical loads, using whatever means provided (such as a main circuit breaker or transfer switch).

2.Let the generator run at no-load for a few min- utes, to stabilize internal engine-generator tem- peratures.

3.Hold Start/Stop switch in its STOP position.
