Section 1 Safety INTRODUCTION: Thank you for purchasing this compact, high performance, air-cooled, engine-driven stationary automatic standby generator set. Every effort was made to make sure that the information and instructions in this manual were both accurate and current at the time the manual was written. However, the manufacturer reserves the right to change, alter or otherwise improve this product or manual at any time without prior notice.
1.1 General Safety Study these safety rules carefully before operating or servicing this equipment. Become familiar with this Owner’s Manual and with the unit. The generator can operate safely, efficiently and reliably only if it is properly installed, operated and maintained. Many accidents are caused by failing to follow simple and fundamental rules or precautions. The manufacturer cannot anticipate every possible circumstance that might involve a hazard.
1.3 Exhaust Hazards • Generator engine exhaust contains DEADLY carbon monoxide, an odorless, colorless, poisonous gas. Breathing carbon monoxide can cause dizziness, throbbing temples, nausea, muscular twitching, headache, vomiting, weakness, sleepiness, inability to think clearly, fainting, unconsciousness or even death. If any carbon monoxide poisoning symptom is experienced, move into fresh air and immediately seek medical attention. • This generator is designed for OUTDOOR installation ONLY.
If this generator is used to power electrical load circuits normally powered by a utility power source, it is required by code to install a transfer switch. The transfer switch must effectively isolate the electrical system from the utility distribution system when the generator is operating (NEC 702). Failure to isolate an electrical system by such means will result in damage to the generator and also may result in injury or death to utility power workers due to backfeed of electrical energy.

2.3 Emission Information The U.S. Environmental Protection Agency (EPA) requires that this generator comply with exhaust emission standards. This generator is certified to meet the applicable EPA emission levels, and is certified for use as a stationary engine for standby power generation. Any other use may be a violation of federal and/or local laws.

2.4.3 Fuel Requirements The engine has been fitted with a dual fuel carburetion system. The unit will run on natural gas or LP gas (vapor), but it has been factory set to run on natural gas. The fuel system will be configured for the available fuel source during installation. Recommended fuels should have a btu content of at least 1,000 Btus per cubic foot (37.26 megjoules per cubic meter) for natural gas, or at least 2,500 Btus per cubic foot (93.15 megajoules per cubic meter) for LP gas (vapor).

Section 3 Operation 3.1 Control Panel Interface The control panel on this unit is intended to only be operated by qualified service personnel. The Control panel interface is located under the lid of the enclosure. Before attempting to lift the lid of the enclosure, verify that both left and right side locks are unlocked. To remove the front cover, lift the cover straight up to disengage the side hooks, then tilt and lift it away from the unit.
Figure 3-2: Generator Control Panel 3.2 Using the Auto/Off/Manual Buttons Button Description of Operation Auto of It (see to t section). Off This button shuts down the engine and also prevents automatic operation of the unit. Manual This button will crank and start the generator. Transfer to standby power will not occur unless there is a utility failure. NOTE: Damage caused by mis-wiring of the interconnect wires is not warrantable. 3.

3.4 Automatic Transfer Operation To select automatic operation: 1. Make sure the transfer switch main contacts are set to their UTILITY position (loads connected to the utility power source). 2. Be sure that normal UTILITY power source voltage is available to transfer switch terminal lugs N1 and N2. 3. Press the AUTO button on the Control Panel Interface. 4. Set the Main Circuit Breaker (Generator Disconnect) to its ON (Closed) position.
3.5 Turning the Generator Off When Operating Under Load NOTE: Important! To turn the generator off during prolonged utility outages to perform maintenance or conserve fuel, follow these simple, but important steps: To turn the generator OFF (while running in AUTO and online): 1. Turn OFF (or OPEN) the main Utility disconnect. 2. Turn OFF (or OPEN) the Main Line Circuit Breaker (MLCB) on the generator. 3. Turn the generator OFF. To turn the generator back ON: 1.
3.6.2 Transfer Back to Utility Power Source When utility power has been restored, transfer back to utility source and shut down the generator. To manually transfer back to utility power and shut down the generator: 1. Set the Main Circuit Breaker (Generator Disconnect) to its OFF (OPEN) position. 2. Allow the engine to run for 2 minutes at no-load to stabilize the internal temperatures. 3. Press the Control Panel OFF button. The engine should shut down. 4.
3.7.3 120V GFCI Outlet/15 Amp Breaker (17 & 20 kW Only) All units are equipped with an external 15 amp, 120 volt GFCI convenience outlet located in the top corner of the compartment. When the generator is running, in the absence of utility power, this outlet may also be used to power items outside the home such as lights or power tools. This outlet may also be used when utility power is present by running the generator in manual mode. This outlet does not provide power if the generator is not running.

4.2.1— Maintenance Log 1. Battery inspection and charge check (recommended every year (1) for the life of the battery) NOTE: Check electrolyte level (unsealed batteries only) every 6 months. Dates Performed: 2. Oil, oil filter and air filter replacement (recommended after the first 25 hours after installation and every 200 hours or 2 years, whichever occurs first) NOTE: Spark plug replacement (recommended every 4 years or 400 hours, whichever occurs first). Dates Performed: 3.
4.3.1— Engine Oil Recommendations To maintain the warranty, genuine Generac replacement parts MUST be used, including Generac oil kits (which include an oil and air filter). Generac oil kits can be obtained through an Authorized Dealer or purchased on-line. To purchase on-line, access the maintenance kits page through [[[ KIRIVEG GSQ or directly at WLST KIRIVEG GSQ. Follow the prompts to enter delivery information and complete the purchase.
Figure 4-2: Oil Filter and Drain Location 4.4 — Changing the Engine Air Cleaner 1. With the generator shut down, lift the lid and remove the front panel. 2. Remove the cover clips and air cleaner cover (11-20kW), or disengage the wire clip and open the air cleaner access door (8kW). 3. Pull out the old air filter and discard. 4. Thoroughly clean the air cleaner enclosure of any dust or debris. 5. Install a new air cleaner. 6.
4.6 — Valve Lash Adjustment After the first six (6) months or 500 hours of operation, check the valve clearance. Adjust if necessary. Important: Please contact the Dealer for service assistance. This is a very important step to ensure longest life for the engine. To check valve clearance: • The engine should be cool before checking. If valve clearance is 0.002" - 0.004" (0.05 - 0.1mm), adjustment is not needed. • Remove spark plug wires and position wires away from plugs. • Remove spark plugs.
Rocker Arm Valve Stem Figure 4-4: Valve Clearance Adjustment 4.7 — Battery Maintenance The battery should be regularly inspected per the Service Schedule: 1. With the generator shut down, lift the lid and remove the front panel. 2. Inspect the battery posts and cables for tightness and corrosion. Tighten and clean as necessary. 3. Check the battery fluid level of unsealed batteries, and if necessary, fill with distilled water only. DO NOT use tap water.
