Operation - Franklin Electric Shallow Well El Manual Del Propietario

Convertible Jet Pump
Consult your local voltage
supply to make
appropriate changes. Check
motor terminal
cover for wiring instructions.
Use permanently enclosed
three-conductor wiring such
as conduit or BX cable. The
pump must be grounded by
attaching the ground wire to
the ground screw in the switch case. The other two wires
are attached to the line terminals of the switch.

OPERATION

SHALLOW WELL INSTALLATION
Connect pump to well as shown in Figure 1. Support
suction pipe so its weight is not carried by the pump.
Installation should include a foot valve in the well or a
check valve close to the pump. If the distance from the
well to the pump is more than 40', a check valve (installed
close to the pump) is recommended in addition to the
foot valve. Special care should be taken to ensure that all
suction fittings are tight and sealed. Otherwise the pump
will not prime.

HORIZONTAL OFFSET SUCTION PIPING
When the pump is offset from the well, the horizontal
offset suction piping may have to be increased in
diameter to reduce the friction loss. The table below
shows recommended pipe sizes, depending on the offset
distance. Pipe from the pump to the well should slope
downward (about 4" to every 10').

DISCHARGE PIPE SIZES FOR SHALLOW WELL
INSTALLATIONS
When the pump is located at a distance from points of
water use, it is necessary to increase the discharge pipe
size in order to reduce friction loss. The Discharge Pipe
Size table shows the recommended sizes.

PRIMING (SHALLOW WELL)
The motor should not be started before
pump is primed.
This is a self-priming pump only when filled with water.
To prime the pump, fill the pump case and suction
pipe completely with water. Install discharge fitting
using thread sealant. After closing faucets, start pump.
Water will start pumping in a few minutes with the time
dependent on the depth of the water level and the length
of the piping. If after a few minutes of running you do not
get water, repeat the priming process as all air was not
discharged from the pump. Once the pump is operating,
open faucets slowly and let pump operate until water
runs clear. If after a reasonable time your water continues
to run sandy or dirty, check with your dealer for further
instruction. No further priming will be necessary unless
the pump is drained for repair or storage, or the foot
valve fails.
DEEP WELL INSTALLATION (DOUBLE PIPE)
Control valve must be used with deep well injector.
The double pipe installation is used for a 4" or larger well.
The Installation should be made as shown in Figure 2.
If plastic piping is used, the suction tapping is 1-1/4"
and the pressure tapping is 1". Mount plastic pipe with
two clamps on both 1-1/4" and 1" adapters. Sufficient
amount of pipe should be used to lower the jet 10 to 15
