Installation

We sincerely appreciate your patronage. For this reason, we have made every effort to provide for a safe, streamlined and cost-effective installation. Because each installation is unique, it is impossible to know of and advise the trade of all conceivable procedures and methods by which installation might be achieved. Neither could we know of possible hazards and/or the results of each method or procedure.

For these reasons, only current licensed electrical

and plumbing professionals should attempt generating set system installations. Installations must strictly comply with all applicable codes, industry standards and regulations.

Your generating set is supplied with this “Operator’s Manual” and a separate “Installation Manual”. These are important documents and should be retained by the owner after the installation has been completed.

For the Owner:

To help you make informed choices and communicate effectively with your installation contractor(s), read

and understand Owner Orientation in this manual before contracting or starting your generating set installation.

To arrange for proper installation, contact the store at which you purchased your generating set, your dealer, a licensed electrician or your utility power provider.

The generating set warranty is VOID unless the system is installed by licensed electrical and plumbing professionals.

Every effort has been made to ensure that information in this manual is accurate and current. However, we reserve the right to change, alter, or otherwise improve the product and this document at any time without prior notice.

For the Installing Dealer/Contractor:

For most applications, the installation manual contains all the information required to properly install and start the generating set. This operator’s manual describes routine operation and owner maintenance procedures.

Owner Orientation

This section provides generating set owners with the information necessary to achieve the most satisfactory and cost effective installation possible.

The illustrations are for typical circumstances and are meant to familiarize you with the installation options available with your generating set. A thorough understanding of these options will provide fundamental control over the cost of your installation, as well as ensure your final satisfaction and security.

Federal and local codes, appearance, noise levels, fuel types, and distances are the factors that must be considered when negotiating with an installation professional. Remember that as the distance from the existing electrical service and gaseous fuel supply increases, and the number of 90 degree bends in the fuel supply increases, compensations in piping and wiring materials must be made. This is necessary to comply with local codes and overcome electrical voltage drops and gaseous fuel pressure drops.

The factors mentioned above will have a direct affect on the overall price of your generating set installation.

In some areas you may need to acquire electrical permits for installing the generating set, building permits for installing gas lines, and permits for noise allowances. Your installer should check your local codes AND obtain the permits before installing the system.

Fuel Factors

An important consideration affecting the entire installation is the type of fuel used by your generating set. The system was factory tested and adjusted using either natural gas or liquid propane (LP vapor). For proper engine function, factors that are inherent to each of these fuels, your location and the duration of possible utility interruptions are important considerations in the following fuel guidelines:

• Use clean, dry fuel, free of moisture or any particulate material. Using fuels outside the following recommended values may cause performance problems.

• In engines set up to run on propane (LP), commercial grade HD5 propane with a minimum fuel energy of 2500 BTUs/ft3 with maximum propylene content of 5% and butane and heavier gas content of 2.5% and minimum propane content of 90%.

Natural gas rating will depend on specific fuel but typical derates are between 10 to 20% off the LP gas rating.

WARNING Propane and Natural Gas are

extremely flammable and explosive, which could cause burns, fire or explosion resulting in death, serious injury and/or property damage.

• DO NOT operate the equipment if the emergency “fuel shut-off” valve is missing or inoperative.

• After the generating set is installed, you should inspect the fuel system periodically.

• NO leakage is permitted.

• DO NOT operate engine if smell of fuel is present or other explosive conditions exist.

Natural gas or LP engines are certified to operate on natural or liquid propane gas. The emissions control system for this engine is EM (Engine Modifications).

Power Decrease at High Altitude or High Temperature

Air density is less at high altitudes, resulting in less available engine power. Specifically, engine power will decrease 3.5% for each 300 meters above sea level and 1% for each 5.6°C above 25°C. Make sure you and your installer consider these factors when determining total generating set load.

Generating Set Location

The actual physical location of your generating set has a direct affect on:

1. The amount of plumbing required to fuel your generating set.

2. The amount of wiring required to control and connect your generating set.

Specific location guidelines are discussed in the installation manual. Acquaint yourself with that information and confer with your installer. Be sure to ask how your site might affect installation costs and compliance with local codes and standards.

• Install generating set outdoors in an area that will not accumulate deadly exhaust gas.

• DO NOT install generating set where exhaust gas could accumulate and enter inside or be drawn into a potentially occupied building or structure.

• It may be required to have a Carbon Monoxide (CO) detector in operating condition in your home. Carbon monoxide detector(s) (A) MUST be installed and maintained indoors according to the manufacturer’s instructions/recommendations. A CO monitor is an electronic device that detects hazardous levels of CO. When there is a buildup of CO, the monitor will alert the occupants by flashing visual indicator light and alarm. Smoke alarms cannot detect CO gas.

WARNING Running engine gives off carbon

monoxide, an odorless, colorless, poison gas. Breathing carbon monoxide could result in death, serious injury, headache, fatigue, dizziness, vomiting, confusion, seizures,

nausea or fainting.

• Operate this product ONLY outdoors in an area that will not accumulate deadly exhaust gas.

• Carbon monoxide detector(s) MUST be installed and maintained indoors according to the manufacturer’s instructions/recommendations. Smoke alarms cannot detect carbon monoxide gas.

WARNING Exhaust heat/gases could ignite

combustibles or structures resulting in death, serious injury and/or property damage.

• Exhaust outlet side of weatherproof enclosure must have at least 1.5 m minimum clearance from any structure, shrubs, trees, or any kind of vegetation.

• Weatherproof enclosure must be at least 1.5 m from windows, doors, any wall opening, shrubs or vegetation over 30.5 cm in height.

• Weatherproof enclosure must have a minimum of 1.5 m overhead clearance from any structure, overhang or trees.

• DO NOT place weatherproof enclosure under a deck or other type of structure that may confine airflow.

• USE ONLY flexible fuel line provided. Connect provided fuel line to generating set. DO NOT use with or substitute any other flexible fuel line.

• Smoke detector(s) MUST be installed and maintained indoors according to the manufacturer’s instructions/recommendations. Carbon monoxide alarms cannot detect smoke.

• DO NOT place weatherproof enclosure in manner other than shown in illustrations.

• Ensure exhaust gas is kept away from any windows, doors, ventilation intakes, soffit vents, crawl spaces, open garage doors or other openings that can allow exhaust gas to enter inside or be drawn into a potentially occupied building or structure. Your neighbor’s may be exposed to the engine exhaust from your generating set and must be considered when installing the unit.

• Wind and air currents should be taken into consideration when positioning the unit.

See the installation manual for full details on safe generating set location.

Important Owner’s Considerations

Engine Oil

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

• DO NOT attempt to crank or start the engine before it has been properly serviced with the recommended oil. This may result in an engine failure.

• Damage to equipment resulting from failure to follow this instruction will void generating set warranty.

The engine is shipped from the factory pre-run and filled with synthetic oil (API SJ/CF 5W-30). 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 Maintenance.

Battery

The installer must supply a rechargeable 12 volt DC starting battery. See Battery in Final Installation Considerations in the installation manual.

With the battery installed, all wiring to transfer switch and generating set completed, utility power supplied to the automatic transfer switch, and the unit in AUTO mode, the battery receives a trickle charge while the engine is not running. The trickle charge

cannot be used to recharge a battery that is discharged.

15 Amp Fuse

The generating set’s 15 Amp fuse is critical to correct system operation. The 15 Amp fuse was removed at the factory to prevent the unit from starting during shipping. Your installer will ensure the fuse is properly installed upon completion of the installation.

completely

Automatic Operation Sequence

The generating set’s control board constantly monitors utility voltage. Should utility voltage drop below a preset level, the control board will signal the engine to crank and start.

When utility voltage is restored above a preset voltage level, the engine is signaled to shut down.

The actual system operation is not adjustable and is sequenced by sensors and timers on the control board, as follows:

CAUTION With the system switch set to AUTO, the engine could crank and start at any time without warning, resulting in minor or

moderate injury.

• 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 generating set or transfer switch.

Utility Voltage Dropout Sensor

• This sensor monitors utility source voltage.

• If utility source voltage drops below about 70 percent of the nominal supply voltage, the sensor energizes a 3 second timer. The timer is used to ‘sense’ brown-outs.

• Once the timer has expired, the engine will crank and start.

Utility Voltage Pickup Sensor

This sensor monitors utility power voltage. When utility voltage is restored above 80 percent of the nominal source voltage, a time delay starts timing and the engine will go to engine cool-down.

Engine Cool-down Timer

When utility power is sensed and the load transfers to the utility source, the engine will go into a cool down period as described below:

• If the generating set has run for MORE than 5 minutes, once the utility transfer occurs, the engine will continue to run for about 1 minute before shutting down.

• If the generating set has run for LESS than 5 minutes, once the utility transfer occurs, the engine will continue to run until 5 minutes has

elapsed before shutting down.

Setting Exercise Timer

The generating set is equipped with an exercise timer. During the exercise period, the unit runs for approximately 20 minutes and then shuts down. Electrical load transfer DOES NOT occur during the exercise cycle (unless an utility power outage occurs).

The generating set will only enter the exercise cycle if the unit is in the AUTO mode and this exact procedure is followed.

To set the exercise timer:

CAUTION With the system switch set to AUTO,

the engine could crank and start at any time without warning, resulting in minor or moderate injury.

• 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 generating set or transfer switch.

NOTICE The generating set is set with a deservice code exercise cycle setting of Tuesday at 2:00 P.M, Central Time. To change the cycle setting, proceed to the following steps:

1. Choose the day and time you want your generating set to exercise.

2. Press and hold the left arrow and right arrow simultaneously for 3 seconds to enter the General Set-Up program mode. See General Set-Up flow chart in Menu Section.

3. Verify and/or set the time and date on the unit.

4. Go to the SET EXERCISE prompt and hit the “OK” button.
