Clog Removal and Wear Plate Clearance
Before attempting to open or service the
pump:
1. Familiarize yourself with this man
ual.
2. Disconnect or lock out the power
source to ensure that the pump will
remain inoperative.
3. Allow the pump to completely cool
if overheated.
4. Check the temperature before
opening any covers, plates, or
plugs.
5. Close the suction and discharge
valves.
6. Vent the pump slowly and cau
tiously.
7. Drain the pump.
This pump is equipped with an inspection cover to
provide easy access to the interior of the pump for
removal of debris and to check the im
peller‐to‐wear plate clearance. Remove the inspec
tion cover and check for clogging any time pump
performance appears to be below the desired ap
plication levels. Check the wear plate clearance
monthly and adjust the clearance if necessary as
described in
Back Cover Installation and Adjust
ment
in Section E,
Maintenance and Repair
. The
recommended impeller‐to‐wear plate clearance is
.010 to .020 inch (0,25 to 0,50 mm).
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.
