Little Giant 14EH Series, Установка, Страница: 3 / 8

Pump can be installed with ABS, PVC, polyethylene or galvanized
steel pipe. Proper adapters are required to connect plastic pipe
to pump.
A union should be installed just above the cover to facilitate pump
removal if necessary.
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.
WIRING
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 feet, 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.

CAUTION: When working on pump or switch, always unplug
pump power cord in addition to removing fuse or shutting of
circuit breaker before working on pump.
