Operation; Maintenance - Franklin Electric SP25A Manual

The electrical power outlet required for this pump is a
separate 15 amp circuit of 115 volts, AC 60HZ, with a
proper fused switch in the line. This must be located
within 8 feet of the pump. The ground terminal on the
plug is provided for your protection. Do not remove.
Plug the pump cord into the 115 volt grounded service
and connect the discharge piping, your pump is then
ready for operation.
3) Sump Preparation Requirements:
a) level bottom - can be levelled with bricks.
b) size: minimum 24" deep x minimum 12" diameter
(Note: pump will operate more effi ciently in an 18"
diameter sump.)
4) Float Switch: (where applicable)
The fl oat switch (if so equipped) is sealed and factory
adjusted to be suitable for most sumps. Be sure that
the fl oat has adequate clearance and cannot become
stuck on the sides of the sump. Do not allow the cord to
interfere with the free movement of the fl oat or to drape
over the motor housing. The cord should be taped to
the pump discharge piping with electricians tape.
NOTE: Range of pumping levels can be varied by
adjusting the free length of cable between the fl oat switch
and the cable clamp. The free length of cable must be
at least 4" to allow free movement of the fl oat. Longer
free length allows a larger pumping range. Always check
operation of switch after making any adjustments!
5) Discharge Piping:
a) The pump has a threaded discharge opening.
b) PVC or ABS adapters may be used to adapt to
other sizes of pipe.
c) We recommend that you not reduce the discharge
pipe size, use as large as possible.
d) Keep piping length to a minimum (extra length
increases friction losses).
e) A check valve must be installed for proper
installation.
Automatic Models
The pump operation is designed to be completely
automatic, the integral switch (if so equipped) is preset
at the factory to turn the pump on and off when the fl uid
level in the tank reaches a specifi c height. Separate,
piggyback-style switches must be carefully adjusted
If the pump is placed into the water while running, it will air
lock. This means that air is trapped in the pump, preventing
it from pumping water. To avoid this, always place the pump
Your pump has been built to give many years of satisfactory
service. No regular maintenance is required since the
pump is completely self lubricating. The following routine
checking procedure is recommended to be carried out
once a year and is especially important for occasional use
applications.
6) Operational Check: (never operate pump dry)
Upon installation manually fi ll the sump to check the
fl oat switch operation. Ensure the start and stop levels
are satisfactory and the fl oat has adequate clearance
to the sump sides. While the pump is operating check
that all connections are tight and are not leaking.
IMPORTANT: To avoid freezing in the discharge line
during cold weather operation drill a 1/4" hole in the
discharge pipe above the check valve in sump pit. This
will allow any liquid in the discharge pipe to drain back
into the sump pit and avoid freezing.
If the back fl ow of water in the discharge pipe causes
the pump to turn on again, then the length of the
discharge pipe needs to be reduced.

OPERATION

during installation to ensure proper operation.
Manual Models
Plug in and unplug the electrical cord as required or
use a certifi ed control for starting and stopping, of equal
or greater horsepower rating than the pump.
AIR LOCKING
in the water when it is off, and then plug it in. If the pump
does air lock, simply unplug it and then plug it back in.

MAINTENANCE

a) Check the power cords and electrical outlet for
damage or corrosion.
b) Ensure there is no build-up of sludge or sediment
in the sump.
c) Manually fi ll the sump to check for correct switch
adjustment and pump operation.
