DESCRIPTION
Little Giant GP-A231/GP-A201 series automatic grinder pumps are
recommended for use in basins or lift stations and are suitable for
pumping residential sewage, effluent, wastewater, and other non-
explosive, non-corrosive liquids.
Little Giant grinder pumps use a cutting mechanism, located on
the suction side of the pump, that cuts solids into a slurry. A semi-
vortex, non-clog impeller then passes this slurry directly through
the volute and into the discharge line.
Little Giant automatic grinder pumps are equipped with a float
switch that allows the pumps to operate automatically by cycling
them on and off. The float switches are attached to the pumps
at a pre-determined tether length of 9". CHECK THE TETHER
LENGTH ON YOUR PUMP TO ENSURE THAT IT HAS NOT
CHANGED DURING SHIPPING. A tether length of more than 9"
could damage the pump by allowing it to run dry.

WARNING: RISK OF ELECTRIC SHOCK. READ INSTRUCTIONS
AND SAFETY GUIDELINES THOROUGHLY. FAILURE TO
FOLLOW THESE COULD RESULT IN SERIOUS INJURY OR

PROPERTY DAMAGE!
SERVICE
WARNING: DURING NORMAL OPERATION THE SWITCH AND
PUMP ARE IN CONTACT WITH WATER. EXERCISE EXTREME
PROTECT
CAUTION WHEN WORKING NEAR THESE AREAS!
Ensure that rising water can not reach electrical connections.
THESE
Refer to the National Electrical Code and local requirements. A
separate branch circuit is recommended for each pump. Do not
use an extension cord.
Always turn off the circuit breaker before touching, servicing, or
repairing the switch or pump.
Do not stand in water while changing fuses, resetting circuit
breakers, or repairing the switch.
This pump is supplied with a grounding conductor. To reduce
the risk of electric shock, be certain that it is connected only to a
properly grounded, grounding-type receptacle or ground wire in
the junction box.
When a pump is in a basin, etc., do not touch motor housing,
pipes or water until unit is unplugged or shut off. If your installation
has water or moisture present, do not touch wet area until all
power has been turned off. If shut-off box is not accessible, call
the electric company to shut off service to the house, or call a
certified electrician for instructions. Failure to follow this warning
can result in fatal electric shock.
In any installation where property damage and/or personal injury
might result from an inoperative or leaking pump due to long term
power outages, discharge line blockage or any other reason, a
backup system with an alarm should be installed.
Do not use to pump flammable or explosive fluids such as
gasoline, fuel oil, kerosene, etc. Failure to follow this warning can
result in personal injury and or property damage.
The pump motor is equipped with an internal thermal protector
switch that opens to stop the motor when exceeding normal
operating temperatures or the pump draws excessive current.
This switch will reset itself and start the pump when cooled to
normal temperatures.

The motor housing contains a dielectric oil to cool
the motor and lubricate the bearings and seals.
This pump is capable of operating with the motor
housing partially exposed for extended periods of
time, providing sufficent motor cooling and bearing
lubrication. However, for the best cooling and the
longest motor life, the liquid level being pumped
should normally be above the top of the cast iron
motor cover.
