Improper impeller rotation will result in damage to the pump. Rotation must
be checked at installation. After completing the wiring and with the disconnect
switch in the "OFF" position, lay pump on the side to observe the direction of
rotation through the intake. NOTE: contact with pump when energized could
result in electrical shock. Turn disconnect switch to the "ON" position momentarily.
The impeller should be rotating counterclockwise. An alternate method is to
observe the kickback of the freely suspended pump as it starts. The kickback
should be in counterclockwise direction looking onto the top of the pump. To
change the direction of rotation, interchange any two of the white, red, or black
wires of the pump at the disconnect box.
Pump must be installed in a suitable gas tight basin which is at least 24" in
diameter and 36" deep, and vented in accordance with local plumbing codes.
Pump must be placed on a hard level surface. Never place pump directly on
clay, earth or gravel surfaces.

Pump can be installed with ABS, PVC, polyethylene or galvanized steel pipe.
Proper adapters are required to connect plastic pipe to pump.
Always install a union in the discharge line, just above the sump pit, to allow for
easy removal of the pump for cleaning or repair.
A check valve must be used in the discharge line to prevent back flow of liquid
into the basin. The check valve should be a free flow valve that will easily pass
solids.
CAUTION: For best performance of check valves, when handling solids install
in a horizontal position or at an angle of no more than 45°. Do not install check
valve in a vertical position as solids may settle in valve and prevent opening on
start-up.
A gate valve should follow the check valve to allow periodic cleaning of the check
valve or removal of the pump.
The remainder of the discharge line should be as short as possible with a
minimum of turns to minimize friction head loss. Do not restrict the discharge
to sizes below 2".
Sewage and effluent applications will require a separate sump vent. A connection
is provided on top of the sump or cover which must be piped to the existing
building vent or extended outside with its own standpipe.
Check local electrical and building codes before installation. The installation
must be in accordance with their regulations as well as the most recent National
Electrical Code (NEC).
To conform to the National Electrical Code, all pumps must be wired with 14
AWG or larger wire. For runs to 250', 14 AWG wire is sufficient. For longer runs,
consult a qualified electrician or the factory.
Pump should be connected or wired to its own circuit with no other outlets
or equipment in the circuit line. Fuses and circuit breaker should be of ample
capacity in the electrical circuit.
MAINTENANCE
If pump does not operate properly, consult the troubleshooting chart. If trouble
cannot be located with these steps shown, consult your pump dealer or take
pump to a Little Giant authorized service center.
CAUTION: When working on pump or switch, always unplug pump power
cord in addition to removing fuse or shutting off circuit breaker before working
on pump.

CLEANING IMPELLER AND VOLUTE

WARNING: DO NOT REMOVE THE SOCKET HEAD CAP SCREWS (ITEM #2
ON PARTS LIST). THE MOTOR SECTION OF YOUR PUMP IS PERMANENTLY
LUBRICATED WITH DIELECTRIC OIL AND SEALED AT THE FACTORY.
REMOVAL OF THESE SOCKET HEAD CAP SCREWS BY ANYONE OTHER
THAN AN AUTHORIZED LITTLE GIANT SERVICE CENTER WILL BREAK THIS
SEAL AND VOID THE WARRANTY.
1. Remove (3) screws (item #11 on parts list) that hold volute to motor hous-
ing.
2. Remove volute and clean impeller and volute passage. Do not use strong
solvents on impeller.
3. Be sure impeller turns freely after cleaning.
