eter 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 backflow 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. See chart below.

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.
