EQUIPMENT DESCRIPTION
This equipment is a revolving field, alternating current Stationary
Emergency Generator. 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, mainline circuit breaker, bat-
tery charger, and protective alarms as explained in the following
paragraph.
The Stationary Emergency Generator incorporates the following
alternator features:
• Rotor and Stator insulation is Class H rated as defined by NEMA
MG1-32.6, NEMA MG1-1.66. The generator is self ventilated
and drip-proof constructed.
• The voltage waveform deviation, total harmonic content of the
AC waveform and telephone influence factor have been evalu-
ated 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 SJ or SH.”
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
n
Any attempt to crank or start the engine
before it has been properly serviced with the
recommended oil may result in an engine
failure.
NOTE:
For temperatures below 32° F, it is strongly recommended 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.
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 deionized water and only low silicate
anti-freeze. If desired, add a high quality rust inhibitor to the rec-
ommended coolant mixture. When adding coolant, always add the
recommended 50-50 mixture.
n
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 operated with a chromate base rust
inhibitor must be chemically cleaned before
adding ethylene glycol base anti-freeze.
Using any high silicate anti-freeze boost-
ers or additives will also cause overheating.
The manufacturer also recommends that
any soluble oil inhibitor is NOT used for this
equipment.
n
Do not remove the radiator pressure cap
while the engine is hot or serious burns from
boiling liquid or steam could result.
n
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 poi-
sonous to them.
