OPERATION - SECTION C
Review all SAFETY information in Section A.
Follow the instructions on all tags, labels and
decals attached to the pump.
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.
OPERATION
This pump is designed to handle most
non‐volatile, non‐flammable liquids
containing specified entrained solids
and corrosives. Do not attempt to pump
volatile, corrosive, or flammable liquids
which may damage the pump or endan­
ger personnel as a result of pump fail­
ure.
Pump speed and operating condition
points must be within the continuous per­
formance range shown on the perfor­
mance curve in Section E on page E-1.
PRIMING
Install the pump and piping as described in IN­
STALLATION. Make sure that the piping connec­
tions are tight, and that the pump is securely
mounted. Check that the pump is properly lubri­
cated (see LUBRICATION in MAINTENANCE
AND REPAIR).
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 Maintenance and
Repair, Section E for further details.
STARTING
Check the fuel level and oil levels in the engine, air
compressor, pump bearings and seal housing.
Make sure the pump is level. Lower the jack stands

This pump is equipped with automatic
liquid level controls, and is subject to
automatic restart. Keep hands and
clothing away from the unit to prevent

sonal injury.
Consult the engine operations manual before at­
tempting to start the unit.
