Automatic Stopping
In the automatic mode, the pump will stop when
the liquid in the wet well or sump lowers and acti-
vates the Off" float switch(s) or Off" setpoint
stored in the optional EPS. The pump will restart
automatically when the liquid rises and activates
the On" float switch(s) or On" setpoint stored in
the optional EPS.
Safety Shutdown System
The unit is equipped with a safety system to auto-
matically shut down the engine under certain con-
ditions. The engine will automatically shut down:
1. If the engine exceeds its safe operating tem-
perature.
2. If the engine oil pressure drops below design
limits.
3. If the engine fails to start within a pre-set peri-
od of time.
4. If the engine speed exceeds the safe operat-
ing range.
5. If the engine V-belt breaks.
Lights on the control panel will indicate which of the
safety features has caused the engine to shut
down.
Should any of the safety features cause the engine
to shut down, the cause must be determined and
corrected before putting the unit back into service.
The engine will not restart until the keyswitch has
been returned to the ‘OFF’ position for at least 10
seconds.
All safety shutdown features are pre-set at the fac-
tory for optimum performance and safety; do not
attempt to adjust these settings.
Never disconnect any of the safety shut-
down features; this will void the warran-
ty and could result in serious damage to
the unit and/or injury to personnel. Safe-
ty shutdown features are pre-set at the
factory; do not attempt to adjust any of
the settings. Determine the cause of
shutdown before
putting the unit back
into service. Consult the factory for ad-
ditional information.
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 equipped with the optional auto-start
control, the float(s) may need to be adjusted to al-
low shorter run and longer cooling periods, if pos-
sible.
This pump is equipped with an automat-
ic starting system, and is subject to au-
tomatic restart. Keep hands and cloth-
ing away from the unit to prevent injury
during automatic operation. Disconnect
the positive battery cable before per-
forming any maintenance. Failure to do
so may result in serious personal injury.
Cold Weather Preservation
In below freezing conditions, drain the pump to
prevent damage from freezing. Also, clean out any
solids by flushing with a hose. Operate the pump
for approximately one minute; this will remove any
remaining liquid that could freeze the pump rotat-
ing parts. If the pump will be idle for more than a
few hours, or if it has been pumping liquids con-
taining a large amount of solids, drain the pump,
and flush it thoroughly with clean water. To prevent
large solids from clogging the drain port and pre-
venting the pump from completely draining, insert
a rod or stiff wire in the drain port, and agitate the
