EQUIPMENT DESCRIPTION

This equipment is a revolving field, alternating cur-rent Stationary
Emergency Generator. It is powered by a propane vapor or natural
gas fueled engine operating at 1800 rpm for 4-pole direct drive
unit. The unit comes complete with a sound attenuated enclosure,
internally mounted muffler, control console, mainline circuit break-
er, battery charger, fuel tank set and protective alarms as explained
in the following section.
All AC connections, including the power leads from the alternator,
and control connections to the transfer switch are avail-able in the
main connection box.
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
Above 80° F (27° C)
32° to 80° F (0° to 27° C)
Below 32° F (0° C)
Any attempt to crank or start the engine
before it has been properly serviced with the
recommended oil may result in an engine
failure.
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.
Equipment Description
Oil Grade (Recommended)
SAE 30W or 15W-40
SAE 20W-20 or 15W-40
See Note
NOTE:

COOLANT RECOMMENDATIONS

Use a mixture of propylene glycol base anti-freeze and deionized
water. Cooling system capacity is listed in the "Specifications"
section. Use only deionized water and only propylene anti-freeze. If
desired, add a high quality rust inhibitor to the recommended cool-
ant 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 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.
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 poi-
sonous to them.
