Standby Generator Sets Equipment Description

EQUIPMENT DESCRIPTION

This equipment is a revolving field, alternating cur- rent generator set. It is powered by a gaseous fueled engine operating at 1800 rpm for 4-pole direct drive units, 3600 rpm for 2-pole direct drive units and 2300 - 3000 rpm for quiet drive gear units. See the Specifications section for exact numbers. The unit comes complete with a sound attenuated enclosure, internally mounted muffler, control console, main- line circuit breaker, battery charger, and protective alarms as explained in the following paragraph.

All AC connections, including the power leads from the alternator, 120 volt battery charger input and control connections to the transfer switch are avail- able in the main connection box.

The generator incorporates the following generator features:

•Rotor and Stator insulation is Class F rated as defined by NEMA MG1-32.6, NEMA MG1-1.66. The generator is self ventilated and drip-proof con- structed.

•The voltage waveform deviation, total harmonic content of the AC waveform and telephone influ- ence factor have been evaluated and are acceptable according to NEMA MG1-32.

ENGINE OIL RECOMMENDATIONS

The unit has been filled with 15W-40 engine oil at the factory. Use a high-quality detergent oil classified “For Service CC, SD, SE, SF.” Detergent oils keep the engine cleaner and reduce carbon deposits. Use oil having the following SAE viscosity rating, based on the ambient temperature range anticipated before the next oil change:

	Temperature	Oil Grade (Recommended)
	Above 80° F (27° C)	SAE 30W or 15W-40
	32° to 80° F (0° to 27° C)	SAE 20W-20 or 15W-40
	Below 32° F (0° C)	See Note

Any attempt to crank or start the engine before it has been properly serviced with the recom- mended oil may result in an engine failure.

NOTE:

COOLANT RECOMMENDATIONS

Use a mixture of half low silicate ethylene glycol base anti-freeze and deionized water. Cooling system capacity is listed in the specifications. Use only deion- ized water and only low silicate anti-freeze. If desired, add a high quality rust inhibitor to the recommended coolant mixture. When adding coolant, always add the recommended 50-50 mixture.

Do not use any chromate base rust inhibitor with ethylene glycol base anti-freeze or chro- mium hydroxide (“green slime”) forms and will cause overheating. Engines that have been oper- ated with a chromate base rust inhibitor must be chemically cleaned before adding ethylene glycol base anti-freeze. Using any high silicate anti-freeze boosters or additives will also cause overheating. The manufacturer also recommends that any soluble oil inhibitor is NOT used for this equipment.

DANGER

Do not remove the radiator pressure cap while the engine is hot or serious burns from boiling liquid or steam could result.

Ethylene glycol base antifreeze is poisonous. Do not use mouth to siphon coolant from the radiator, recovery bottle or any container. Wash hands thoroughly after handling. Never store used antifreeze in an open container because animals are attracted to the smell and taste of antifreeze even though it is poisonous to them.

For temperatures below 32° F, it is strongly recom- mended to use the optional Cold Weather Start Kit (part number listed in the Specification Section). The oil grade for temperatures below 32° F is 5W- 30 synthetic oil.
