EQUIPMENT DESCRIPTION
This equipment is a revolving field, alternating current Stationary
Emergency 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, inter-
nally mounted muffler, control console, mainline circuit breaker,
battery charger, and protective alarms as explained in the following
paragraph.
All AC connections, including the power leads from the alterna-
tor, 120 volt battery charger input and control connections to the
transfer switch are available in the main connection box.
The Stationary Emergency Generator incorporates the following
generator features:
• Rotor and Stator insulation is Class H rated as defined by NEMA
MG1-32.6, 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 5W-20 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.
When changing the engine oil, be sure to use 5W-30 engine oil
(synthetic oil is recommended).
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:
For temperatures below 32° F, it is strongly recommended to
use the optional Cold Weather Start Kit. The oil grade for tem-
peratures 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.
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 eth-
ylene 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.
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.
