Operation

Wet Stacking

The unit is powered by a diesel engine. Diesel engines
are subject to "wet stacking" if lightly loaded. Wet
stacking occurs when an engine is run at less than 30%
of its full load capacity, causing unburned fuel to
accumulate in the exhaust system. Wet stacking can be
detected by continuous black exhaust when the unit is
under a constant load. It can also cause fouling of
injectors and buildup on engine valves. Diesel engines
operate properly when applied loads are between 30%
and 100% capacity. Appropriate generator sizing is
determined by the anticipated load.
If the unit is in a wet stack condition, load the unit heavily
for five hours or until the exhaust is clear.

Customer Convenience Outlets

See Figure 3-9. The unit is equipped with two
convenience outlets for powering accessories or tools
from the generator. Power is supplied to the outlets any
time the engine is running and the 240VAC outlet breaker
is switched ON (I). Each outlet has an individual circuit
breaker, located on the control box. See

See Figure 3-9. The circuit breakers are labeled with the
corresponding voltage for the receptacle they protect.
With all of the lights OFF, full generator power output is
available to the receptacles.
NOTE: All equipment or load panels connected to the
generator MUST be properly grounded. If these
appliances do not have grounded plugs, a ground wire
MUST be added between the equipment and the
grounding stud on the receptacle panel per the National
Electrical Code (NEC), state, and local regulations.

Shutting Down the Unit

Check with personnel using power supplied by the unit
and let them know the power is going to be turned off.
Verify the power shutdown will not create any hazards by
accidentally turning off equipment that needs to remain
running (pumps, compressors, lights, etc.).
1. Remove all loads from the outlets.
2. Switch the individual circuit breakers for each light
OFF (O).
3. Switch the main circuit breaker OFF (O).
4. Turn the Engine Start switch OFF (O).
NOTE: Disconnect the battery if the unit is to be stored
for an extended period. Refer to the engine operator's
manual for additional extended storage procedures.
Shutting Down the Unit (with
PowerZone Controller, If
Equipped)
Check with personnel using power supplied by the unit
and let them know the power is going to be turned off.
Verify the power shutdown will not create any hazards by
accidentally turning off equipment that needs to remain
running (pumps, compressors, lights, etc.).
1. Remove all loads from the outlets.
2. Turn the lights OFF using the controller.
3. Switch the outlet breaker OFF (O).
4. Press the Stop (O) button.
5. After the unit shuts down, switch the main circuit
breaker OFF (O).
NOTE: Disconnect the battery if the unit is to be stored
for an extended period. Refer to the engine operator's
manual for additional extended storage procedures.

Automatic Shutdown

This unit is equipped with a low oil pressure and high
coolant temperature automatic shutdown system. This
system will automatically shut off the fuel supply to stop
the engine if oil pressure drops too low or the engine
exceeds normal operating temperature. Return the main
circuit breaker to the STOP position to reset the unit after
the cause of shutdown has been determined.
Lower Radiator Hose Heater (If
Equipped)
The lower radiator hose heater is designed to prevent
engine coolant from freezing in extreme cold weather
conditions. While the heater is designed to be operated
overnight if necessary, two to five hours of heating just
prior to starting is usually sufficient for proper engine
starting.
