box to the MANUAL" position, then press and hold
the ENTER" button until the engine starts.
Pump speed and operating condition
points must be within the continuous per-
formance range shown on the curve on
Page E-1.
Automatic Starting
With the float system installed, follow the proce-
dures outlined for manual starting and adjust the
throttle to the desired flow rate. Turn the key switch
to OFF", then move it to the AUTO" position.
The pump will start automatically when the liquid
level in the sump or wet well increases and the
float(s) rise to the on" position. An alarm will sound
and the control box will begin a countdown display
before the unit starts. When the liquid is sufficiently
pumped down, the unit will automatically shut
down.
The unit can be stopped while in the AUTO" mode
by moving the key switch to the OFF" position.
NOTE
If the key switch is moved to the OFF" position
while in the AUTO" mode, the engine will stop.
However, the auto-start process will continue as
soon as the key switch is moved back to the AUTO"
position.
The control panel is equipped with high oil temper-
ature, low oil pressure, engine overspeed and en-
gine overcrank safety shutdowns. If any of these
problems occur, the engine will not start. When the
problem is corrected, turn the key switch to the
OFF" position to reset the control.
Priming
The pump will begin to prime upon startup. The air
in the suction line will be discharged from the educ-
tor discharge line. Complete priming is indicated
by a positive discharge pressure reading.
If full priming is not achieved, the discharge check
valve may be malfunctioning. If this occurs, shut
down the pump and consult the separate Mainte-
nance and Repair manual for further details.
Routine Operation
Do not operate an internal combustion
engine in an explosive atmosphere.
When operating an internal combustion
engine in an enclosed area, make sure
exhaust fumes are piped to the outside.
These fumes contain carbon monoxide,
a deadly gas that is colorless, tasteless
and odorless.
Adjust the engine speed to achieve the desired
output. Do not exceed the factory set engine speed
and system operating pressure. Do not operate
below the recommended operating speed (if appli-
cable).
Never tamper with the governor to gain
more power. The governor establishes
safe operating limits that should not be
exceeded. Refer to the Performance
Curve in the separate Parts List Manual
for the maximum continuous operating
speed for this pump.
Operation In Extreme Heat
The safety shutdown system will automatically
stop the unit if engine operating temperature ex-
ceeds design limits. If engine over-temperature
shutdown occurs, allow the unit to cool before re-
starting.
If engine overheating continues, check the engine
lubricant level and viscosity. Consult the engine
operation manual for the recommended lubricant
for operation in extreme heat.
If the unit is being operated in the automatic mode,
adjust the float(s) to allow shorter run and longer
cooling periods, if possible.
