1.6.3 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 or 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:
1.6.4 COOLANT
Use a mixture of half Propylene glycol base antifreeze
and half de-ionized water. Use only de-ionized water
and Propylene glycol antifreeze. When adding cool-
ant, always add the recommended 50-50 mixture.
DANGER

Do not remove the radiator pressure cap while
the engine is hot or serious burns from boiling
liquid or steam could result.

Propylene 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.

Do not use any chromate base rust inhibitor
with propylene glycol base antifreeze. Using any
high silicate antifreeze boosters or additives also
will cause overheating. It is also recommend that
any soluble oil inhibitor is NOT USED for this
equipment.

1.7 GENERATOR AC LEAD
CONNECTIONS
The electrical wires in the unit’s AC connection
(lower) panel should be installed according to the
number of leads and the voltage/phase required for
the application. If there is any question regarding
lead connection, refer to the wiring diagrams at the
back of this manual.
1.7.1 FOUR-LEAD, SINGLE-PHASE STATOR
Four-lead generators are dual voltage coils or wind-
ings (Figure 1.1). Units may be assigned the following
voltage code:
• “A” units are rated 120/240 VAC, single-phase, 60
Hertz.
Each stator winding in this case delivers a 120 VAC
output. Connecting the two windings in series results
in a 240 VAC output.
The neutral line is formed by a junction of stator
leads 22 and 33. Therefore, a 120 VAC load can be
connected across leads 11 and neutral, or across
leads 44 and neutral.

1.8 GENERATOR AND LOAD
COMPATIBILITY
The generator must be fully compatible with the
rated voltage, phase and frequency of the connected
electrical loads. The generator, connected electrical
devices, or both, can be damaged if voltage, phase
and frequency are not compatible.
NOTE:
This manual assumes that the standby generator
has been properly selected, installed and inter-
connected by a competent, qualified electrician
or installation contractor. Once the installation is
complete, do nothing that may result in noncom-
patibility between the generator and connected
electrical loads.
