Winco PSS21-3 Liquid-Cooled Packaged Sta

Owner's Manual

The Winco PSS21 is an 1800 RPM standby generator. With a new housing design, this generator is our cleanest design to date. We have substantially reduced the number of exposed bolts, added large removable panels for ease of maintenance and quick release oil and coolant fluid check plates are among the improved features of this design. Contact a sales representative for additional information.

This generator comes standard with selectable fuel and is available in 120/240 1-PH, 120/208 3-PH, 120/240 3-PH, and 277/480 3-PH.

The 4 cylinder, overhead valve GM 3.0L engine meets EPA/Carb Emission Regulations for LSI Engines. All engine functions are controlled by an engine mounted ECM. The engine features include an electronic ignition, engine blockheater and vapor fuel system. A critical grade muffler is installed to reduce engine noise levels. Battery rack, cables, and battery tender (charger) are factory installed. A BCI Group 24 650 CCA battery must be purchased separately. Engine cooling is provided by a unit mount radiator. The engine is equipped with a belt driven pusher type fan.
