Important Owner’s Considerations

Engine Oil

notice

Any attempt to crank or start the engine before it has been properly serviced with the recommended coolant or oil will result in equipment failure.

•Refer to Maintenance in the Operator’s Manual and engine manual for coolant and oil fill information.

•Damage to equipment resulting from failure to follow this instruction will void engine and generator warranty.

This engine is shipped from the factory pre-run and filled with non-synthetic oil (API SL 10W-30W). This allows for system operation in a wide range of temperature and climate conditions. Before starting the engine, check oil level and ensure that engine is serviced as described in the engine operator’s manual.

NOTE: The use of multi-grade oil does not alter the required oil change intervals described in the engine operator’s manual.

Coolant System

This engine is shipped from the factory filled with a

50-50 mix of automotive (Dex-Cool™ orange) anti-freeze and water. This will provide optimum year round protection against freezing, boiling and corrosion. The coolant system incorporates a water heater that operates when ambient temperature is below 80ºF AND utility power is present at the transfer switch. Before starting the engine, check coolant level as described in the engine operator’s manual.

Battery

The installer must supply a sealed, rechargeable 12 Volt DC, 650 Cold Cranking Amps (CCA) 55 amp hour starting battery. The battery may not be at full charge when installed. If battery voltage is below 12 Volts, charge the battery. See Battery in the Maintenance section for details.

15 Amp Fuse

The generator’s 15 Amp fuse is critical to correct system operation. Your installer will ensure the fuse is properly installed upon completion of the installation.

To select automatic operation, do the following:

1.Confirm 15 Amp fuse is installed in control panel.

2.Set the main distribution panel circuit breaker that sends utility voltage to the transfer switch to ON.

3.Set the generator’s main circuit breaker to its ON position.

4.Set the control panel System switch to AUTO.

caution

With the system switch set to AUTO, the engine may crank and start at any time without warning. Such automatic starting normally occurs when utility source voltage drops below a preset level or during the normal exercise cycle.

•To prevent possible injury that may be caused by such sudden starts, always set the system switch to OFF if performing maintenance on the system.

•Remove the 15 Amp fuse before working on or around the generator or transfer switch.

Checking Automatic Operation

To check the system for proper automatic operation, proceed as follows:

1.Turn OFF main distribution panel circuit breaker sending power to automatic transfer switch.

The engine will crank and start when utility voltage is lost and the sensor has timed out. Let the system go through its entire automatic operation sequence.

2.With generator output supplying its loads, turn ON main distribution panel circuit breaker that supplies utility power to Automatic Transfer Switch.

3.The automatic transfer switch will transfer loads back to utility power after 5 minute minimum run time and utility is restored.

4.The generator will run for an additional one minute for engine cool down, then shut down.

NOTE: If utility is restored and generator does not shut down after 10 minutes, set system switch to OFF and contact your installer or local service center.

This completes the test procedures for automatic operation. The home generator will now start automatically and will supply power to the transfer switch when utility power is lost.
