Page 3: Generator Installation
Keep hands, feet, clothing, etc., away from drive belts, fans and other moving or hot parts. Never remove any drive belt or fan guard while the unit is operating. Adequate, unobstructed flow of cooling and ventilating air is critical to prevent buildup of explosive gases and to ensure correct generator operation. - Page 4 NFPA 0, LIFE SAFETY CODE NFPA 0, STANDARD FOR EMERGENCY AND STANDBY POWER SYSTEMS NFPA 0, STANDARD TYPES OF BUILDING CONSTRUCTION NOTE: It is essential to use the latest version of any standard to ensure that the generator and its accessories comply with all the applicable standards and local codes.
- Page 5 Do not open or mutilate the battery. Released electrolyte can be toxic and harmful to the skin and eyes. The battery represents a risk of high short-circuit current. When working on the battery, always remove watches, rings or other metal objects, and only use tools that have insulated handles.

Page 6: Before You Begin
Carefully read and follow all of the procedures and safety precautions detailed in the installation guide. If you do not completely understand any portion of the installation manual, technical manual or other factory-supplied documents, contact an authorized dealer for assistance. Fully comply with all relevant NEC, NFPA and OSHA standards as well as all federal, state and local building and electric codes. - Page 7 Make sure the lifting equipment you’ll be using has sufficient capacity to safely handle the weight of the generator. Use nylon lifting straps and connect them to the lifting eyes on each corner of the base frame to avoid damaging the enclosure. Set the generator onto the pad so that the gravel bed extends several inches beyond the generator on all sides.
- Page 8 Check the engine oil, and if necessary, add enough of the recommended oil to bring the level up to the FULL mark on the dipstick. Be careful not to overfill the crankcase. Converting To LP Vapor The generator was configured for natural gas operation at the factory.

Page 9: Installing & Connecting Gas Lines
Replace the fuel hose and clamp. Then reconnect the wires to the solenoid. Finally, insert the plastic plug that came with the generator into the hole on the bottom of the air cleaner base. Installing & Connecting Gas Lines Both natural gas and LP vapor are highly volatile substances, so strict adherence to all safety procedures, codes, standards and regulations is essential. - Page 10 When connecting the gas line to the generator, use a short section of UL Listed or AGA- approved flexible fuel line in accordance with local regulations. The purpose of the flexible fuel line is to ensure that vibration from the generator does not cause a gas leak at one of the connection points, so it’s important that the line be installed with as few bends as possible.

Page 11: External Electrical Connections
External Electrical Connections Drill a ¾ inch hole and feed the conduit through the hole. Remove the knockout in the back of the connection box, feed the wires through the back of the box and secure the conduit with the lock nut. Seal the hole with silicone caulk. - Page 12 Installing The Automatic Transfer Switch Before beginning any installation, make sure power is shut OFF to the main distribution panel and carefully read the Installation Guide that came with your transfer switch. The distributed load center switch must be mounted close enough to the main distribution panel to accommodate the two-foot, pre-wired conduit.
- Page 13 When three-conductor wiring is used, two 0 volt circuits will often share the same neutral wire. To avoid overloading the neutral, you should either move BOTH of the circuits that share the neutral or don’t move either of them. When moving two circuits with a shared neutral, they should be connected to adjacent positions (one above the other) in the transfer switch.

Page 14: Operational Tests
Install a -pole breaker in the distribution panel to protect the transfer switch. The required Amp rating of the breaker depends on which transfer switch you’re using, so refer to the Installation Guide before purchasing the breaker. Install the breaker in two adjacent empty slots (one above the other) in the main panel. - Page 15 Locate the transfer handle and insert the metal end into the slot in the main contactor assembly. Pull the handle DOWN to move the main contacts to the standby power (generator) position. NEVEr OPErATE THE TrANSFEr SWITCH MANuALLY WHEN LOADS ArE CONNECTED.
- Page 16 Use the transfer handle to move the main contacts in the transfer switch to the UP (utility) position. Switch the -pole breaker ON in the distribution panel. Now switch the generator’s main breaker ON and put the mode switch in AUTO. Shut OFF utility power and make sure the generator starts automatically.
- Page 17 After the engine has completed its cool down cycle and shut down, shut OFF utility power again. When the generator is supplying power to the transfer switch, move the breakers in the switch to the ON position one at a time until the generator has accepted the entire emergency load.
-
Page 18: Setting The Automatic Exercise Function
Shut OFF utility power again. The generator should start and the entire emergency load should transfer to the generator. Close the main breaker to restore utility power and allow the engine to cool down and shut itself OFF. Setting The Automatic Exercise Function With the mode switch in AUTO, press the EXERCISER switch. - Page 19 Notes...
