OPERATION
PAGE C − 4
When the liquid level in the sump or wet well is suffi-
ciently pumped down, the unit will automatically
shut down.
NOTE
If the keyswitch is moved to the OFF" position
while in the auto-start mode, the engine will stop.
However, the auto-start process will continue as
soon as the keyswitch is moved back to the AUTO
START" position. To cancel the auto-start process,
press the OFF/SET" button.
The control panel is equipped with high oil temper-
ature, low oil pressure, V-belt and start failure (3 at-
tempts) safety shutdowns. If any of these problems
occur, the red Double Lightning Bolt" light will illu-
minate to indicate a system fault. When the prob-
lem is corrected, press the OFF/SET" button to re-
set the control.
NOTE
The OFF/SET" button has dual functionality when
in program mode. If necessary, consult the factory
for details on programming functions.
The unit can be started manually with the key-
switch in the AUTO START" position by pressing
the white MAN" button. The Single Lightning
Bolt" light will illuminate in conjunction with an au-
dible alarm before the unit starts.
Stop the unit manually by pressing the OFF/SET"
button.
Automatic Starting (John Deere Powered Units
With Float System)
If the unit is equipped with the autostart control sys-
tem, install the float(s) as described in INSTALLA-
TION, Section B.
Follow the procedures 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 (All Engine Driven
Models)
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
