Before installing the pump, the
drainage system served should be
flushed out and the pump basin thoroughly cleaned
of any foreign matter [such as chunks of wood,
stones, wire, sludge, and rags] that is liable to affect
pump operation, damage the unit, or clog the
strainer. Also check the float rod guide [21] to see
that the rod alignment is correct so that the float rod
mechanism is able to move freely.
Do not work under a suspended
object unless there is a positive
support under it to stop its fall in event of sling or
hoist failure. Disregard of this warning could result
in grave personal injury.
Never attempt to lift, lower or raise
the sump pump with the motor power
cord. Always use a sling or wire rope, secured only to
pedestal, and a hoist to lower or raise pump.
SETTING THE UNIT:
If the pump is of the floor plate
type, check pump length (from bottom of floor plate
to bottom of strainer) and compare with basin depth;
be sure of minimum 4-inches clearance. Se the unit
carefully into the basin, taking precautions not to
crush or damage the float. Face the discharge pipe
as desired and bolt the unit firmly into place.
PIPING:
The discharge pipe should include a union,
a horizontal swing check valve, and a gate valve all
near the pump, and should be run to a point above
the sewer level so as to drop into the sewer from
above. This facilitates easy removal of the unit for
repairs or cleaning and helps prevent backing-up of
sewer water in the event of high water conditions.
The size of the discharge pipe should not be smaller
than that of the discharge connection on the pump,
and where runs are long should be at least a size or
two larger.
It is important that the pipe connections to the unit
be made so that there is no pipe strain upon the
unit. Where quiet operation is important a small
section of rubber hose can be included in the
discharge line to prevent transmission of vibration
noise.
CONTROLS:
With standard single phase LG pumps,
no controls or wiring are necessary. These units are
Due to automatic switch opera-
tion
of
sump
pumps,
tie
the
main disconnect switch open or remove fuses from
main lines before attempting lubrication,
self contained, have the switch already mounted and
wired, and are provided with cords and standard
plugs for connection to any socket. But the line used
must have the proper electrical characteristics and be
provided with the proper fuse. In the event that this
line is used for other appliances or for lighting, a
special fuse serving only the sump pump should be
incorporated in the line.
CAUTON
Before attempting hook-up,
handling, or repair of electrical
wiring, be certain that the electrical supply source is
shut off. An electrical shock from contact with live
wires or cords can be fatal.
WARNING
WARNING
The single phase LGL2 pumps must be wired to the
service provided. Always provide a fused, manual,
motor disconnect switch in the main line. If a fused
motor disconnect switch is not provided in the motor
circuit, there will be danger to life when necessary to
work on the circuit, or there may be danger of fire if
the motor is overloaded and overheats.
CAUTION
All three phase motors must be wired to the service
through a magnetic starter. The float switch provided
must only be used to pilot the magnetic starter in
three phase installations.
Be sure the voltage and frequency
Indicated on motor nameplate are the
same as service provided. If the motor has been
wired at the factory, note the voltage caution card. If
available service is other than that indicated, consult
motor manufacturer’s instructions for proper wiring
changes.
CAUTION
WIRING:
Connect the electric service to the controls
and make inter-control electrical connections when
necessary according to wiring instructions accom-
panying the switches, using conduit and wire sizes
as required by local and national electrical codes. It
is best to include a short section of flexible conduit
adjacent to the motor for convenience in pump or
motor repair.
FUSES:
It is recommended that Fusetron (duel
element) fuses be used if not other thermal or motor
protecting device is used. The Fusetron provides for
motor protection against burn-out. Care must be
taken in selecting the proper size Fusetron. When a
fuse blows it indicated that something is wrong
either in the motor, pump, switch, fuse rating or
service. Do not replace a fuse until you find and
remove the cause of the blow-out.
LUBRICATION
WARNING
mechanical and electrical examinations, or repairs.
attach a card “DO NOT CLOSE SWITCH – PUMP
REPAIR IN PROGRESS.” Disregard of this warning
may result in serious personal injury or death.
