Take special note and follow all warnings on the unit labels and in the manuals.
TESTING POLICY: UL Automatic Transfer Switch Sizes UNIT LINE SIDE CONTACTOR Before any generator is shipped from the factory, it is fully checked for performance. The generator is loaded to its full capacity, and the voltage, current, and frequency are carefully checked. PSS15B4W Rated output of generators is based on engineering tests of typical units, and is subject to, and limited by, the temperature, altitude, fuel, and other conditions specified by the manufacturer of the applicable engines.

ENGINE GENERATOR SET MOUNTING WARNING - Personal Injury The enclosures on these units can become very hot adjacent to the exhaust areas. Special care must be taken when installing these units to insure that the risk of contact by people is minimized. The unit’s main frame should be bolted solid to a four to six inch thick cement pad. The engine-generator is mounted on a sub-frame which is isolated with special shock mounts on the main frame.
************* ***** WARNING **** ************* PERSONAL DANGER - Do not use galvanized pipe in fuel line runs. The galvanized coating can become eroded and flake off, causing possible obstructions in the regulator or fuel valve. The results could range from inoperative engine start to hazardous fuel leaks.
If you are going to operate on LPG you will need to move the fuel line from the NG port to the LPG port on the fuel outlet tee. These two ports have different orifice inserts installed in them, which provide proper engine operation with no further adjustments. When moving the fuel line from one port to the other be sure not to kink or bend the line. Use as large a sweeping curve as possible and never shorten the fuel line. For proper operation the fuel line must stay the same length as it was shipped.
BATTERY CHARGING Units equipped with electric start have a small flywheel charger built into the engine flywheel assembly for recharging the starting battery. This flywheel charger generates a small AC current that passes through a rectifier/regulator assembly on the engine to produce a DC charging current. This circuit is not designed to be used as a battery charging circuit to recharge dead batteries.
