vent injury during automatic operation.
Disconnect the positive battery cable
before performing any maintenance.
Failure to do so may result in serious
personal injury.
Consult the operations manual furnished with the
engine.
Manual Starting
On initial start-up, set the engine speed at the half-
throttle position. Turn the keyswitch on the control
box to the “START” position until the engine starts.
Release the key and the switch will return to the
“RUN” position.
After the engine starts and the unit is fully primed,
adjust the engine RPM until the desired flow rate is
achieved.
Pump speed and operating condition
points must be within the continuous per-
formance range shown on the curve on
page E-1.
Automatic Starting
If the unit is equipped with the optional autostart
control system, install the float(s) as described in
INSTALLATION, Section B.
Follow the procedures outlined for manual starting
and throttle adjustment, then turn the key to the
“AUTO START” position.
NOTE
For security purposes, the key can be removed with
the switch in the “AUTO START” position.
Press and hold the white “AUTO” button on the
control panel until the red “AUTO” light illuminates.
The auto-start system is now armed.
NOTE
The unit can continue to be started manually with
the keyswitch in the “AUTO START” position by
pressing the white “MAN” button on the control. The
“Single Lightning Bolt” light on the control will illu-
minate in conjunction with an audible alarm before
the unit starts. The unit can then be stopped manu-
ally by pressing the “OFF/SET” button.
In the auto-start mode, the “Single Lightning Bolt”
light will illuminate in conjunction with an audible
alarm when the liquid level in the sump or wet well
rises and activates the float(s). The light will blink
and the alarm will sound for approximately 8 sec-
onds before the unit starts.
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.
