STOPPING
Manual Stopping
In the manual mode, reduce the throttle speed
slowly, and allow the engine to idle briefly before
shutting down the engine.
If the application involves a high discharge
head, gradually close the discharge
throttling valve before stopping the pump.
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” liquid level device(s). The pump will
restart automatically when the liquid rises and acti
vates the “On” liquid level device(s).
Safety Shutdown System
The unit is equipped with a safety system to auto
matically shut down the engine under certain con
ditions.
Displays 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.
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.
PERIODIC CHECKS
Seal Cavity and Bearing Lubrication
Both the seal and bearing cavities were fully lubri
cated at the factory. Check the lubrication levels
before startup, and regularly thereafter as indi
cated in Section E,
Maintenance and Repair
.
When lubrication is required, use
only
SAE No. 30
non‐detergent oil.
Bearing Temperature Check
Bearings normally run at higher than ambient tem
peratures because of heat generated by friction.
Temperatures up to 160
_
F (71
_
C) are considered
normal for bearings, and they can operate safely to
at least 180
_
F (82
_
C).
Checking bearing temperatures by hand is inaccu
rate. Bearing temperatures can be measured ac
curately by placing a contact‐type thermometer
against the housing. Record this temperature for
future reference.
A sudden increase in bearing temperatures is a
warning that the bearings are at the point of failing
to operate properly. Make certain that the bearing
lubricant is of the proper viscosity and at the cor
rect level (see
LUBRICATION
in Section E,
Main
tenance and Repair
). Bearing overheating can
also be caused by shaft misalignment and/or ex
cessive vibration.
When pumps are first started, the bearings may
seem to run at temperatures above normal. Con
tinued operation should bring the temperatures
down to normal levels.
Engine Fuel Filter
Consult the manual accompanying the engine,
and change the fuel filter periodically as indicated.
If operated under extremely dusty and/or humid
conditions, change the filter more frequently. Irreg
ular performance and loss of power usually indi
cate a dirty fuel filter.
Engine Oil
The engine was lubricated for test at the factory.
However,
always
check the lubrication level before
startup.
