Read and understand all instructions in the manual before starting and operating the generator set. PROPER USE AND INSTALLATION You must be sure your new engine generator set is: * * * * * * * USING THIS MANUAL Congratulations on your choice of a Winco generator set. You have selected a high-quality, precision-engineered generator set designed and tested to give you years of satisfactory service.
b. c. SAFETY INFORMATION This engine generator set has been designed and manufactured to allow safe, reliable performance. Poor maintenance, improper or careless use can result in potential deadly hazards; from electrical shock, exhaust gas asphyxiation, or fire. Please read all safety instructions carefully before installation or use. Keep these instructions handy for future reference. Take special note and follow all warnings on the unit labels and in the manuals.
TESTING POLICY: 2) ENGINE/GENERATOR 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. PSS8000 - The engine generator set consists of a Briggs & Stratton Vanguard, two cylinder, air cooled engine equipped to run on L.P. or N.G. fuel. The engine operates at 3600 rpm and frequency regulation is maintained by the engine governor within 4 cycles variation (62.
** NOTICE ** The rated power of each engine-generator is limited by the temperature, altitude and all other ambient conditions specified by the engine manufacturer. Engine power will decrease 3-1/2% for each 1000 ft. above sea level, and will decrease an additional 1% for each 10 degrees Fahrenheit above 60 degrees Fahrenheit. This unit will automatically transfer if a power outage occurs while running in an exercise mode.
INSTALLATION FUEL INSTALLATION General Information The fuel supply should be as close as possible to the engine. This will reduce the installation cost of fuel runs. The information in this manual is offered to assist you in providing the proper fuel for your engine. However, this information is only provided to inform you of the engine’s requirements and assist in making you aware of the decisions you must make.
regulator in the fuel line will interfere with each other. When this two (2) stage regulator system is used, a fuel line size of 1/2 to 5/8 inch is generally adequate for distances up to 300 feet from the primary to the secondary regulator. (Consult your local fuel supplier for your exact requirements.) The appropriate line size from the table below is then installed from the second regulator to the generator set.
Adjust back and forth until the highest Hz is achieved. Do not turn the valve richer after the Hz quits rising, this would cause the engine to run rich. If the Hz is out of upper or lower limits, a governor adjustment will be necessary.

On the PSS8000 & PSS12000 see your engine manual for governor adjustment procedures.
7. If the pressure is correct, remove the meter and reinstall the pipe plug. 8. You are now ready to make the final fuel mixture adjustment. Refer to adjustment section in this manual. PSS8000 - A customer supplied twelve-volt BCI group U1 battery rated 235 CCA (minimum) is required to complete the installation. Install the highest CCA rated battery available for best cold weather starting performance.
MOUNTING THE AUTOMATIC TRANSFER SWITCH (A.T.S.) ************* ***** WARNING ***** ************* EQUIPMENT DAMAGE- Protect the switch from construction grit and metal chips to prevent a malfunction or shortened life of the switch. FIGURE 3 The Automatic Transfer Switch connects the load (lights, furnace, outlets, etc.) to the normal power line during standby. When normal power fails, the A.T.S.
AT 240 VOLTS. You must also take this into consideration when deciding whether to install an emergency distribution panel. PSS20000 - The Automatic Transfer Switch shipped with the PSS20000 system has a 225 Amp line side contactor installed to handle your normal power needs and a 100 Amp generator side contactor to handle the emergency generator output. Before installing the A.T.S. you must first ensure that the 225 Amp line side contactor will be sufficient to handle your complete service. See Figure 5.
PSS20000 Single Phase Generator Connections To gain access to the customer connections, remove the panel the warning light and the selector switch are mounted on, inside the left hand access door. Both AC and DC connections are made behind this panel. Three AC power leads are required between the generator and the A.T.S. The power leads coming into this connection box from the generator end are run in parallel. (i.e.
D.C. ELECTRICAL INTERCONNECTION Setting the Exerciser Program: *******CAUTION****** 1. Position the top right hand (RUN) slide switch to the right hand position. Never run the AC and DC wiring in the same conduit. 2. Position the top left hand (AUTO) slide switch to the center position. PSS8000 Three control wires are required to be installed between the A.T.S. panel and the generator control terminal box. Depending on the distance 14 to 16 gauge stranded wire should be used.
INITIAL START UP ************* ***** WARNING ***** ************* DO NOT jump start these engine generator sets. Starting these units on a low battery or jump starting them will cause damage to the engine control module. Use the following check list to verify correct installation before starting the engine: 1 Engine oil.* Check level & fill as required with proper grade/qty. 2 Engine coolant.* Check level & fill as required with proper mixture. 3 Unit mounting base properly bolted down.
