DISCHARGE PIPE SIZES FOR INSTALLATION
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 table below shows
the recommended sizes.

PRIMING
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
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 instructions. No further
priming will be necessary unless the pump is drained for
repair or storage, or the foot valve fails.

MAINTENANCE
LUBRICATION
The pump requires only water for lubrication and must
never be run dry.
DRAINING
If your pump must be drained for service or to prevent
freeze damage, remove the discharge fitting and the drain
plug from the pump case. Note; while this will drain the
pump, it will not necessarily drain all unprotected parts of
the piping system.
To drain tank, disconnect the piping at the tank outlet. The
Air Volume Control can be drained by unscrewing fittings
and turning control upside down. This will allow water
back into tank where it will drain. All piping exposed to
freezing should be drained.

SERVICE AND DISASSEMBLY

box leads are disconnected or power is turned
off. After reassembling pump, refer to priming
instructions before running.
If you experience problems with your pump, determine the
trouble from the service check list. (TROUBLESHOOTING)
If the shallow well injector needs servicing, it can quickly
be removed from the pump without disturbing pump or
piping. If you need to service the impeller, motor, or seal,
first disconnect the pressure line from the pressure switch
and remove the bolts holding the bracket to the pump
case, and take off the motor and the bracket assembly,
(you do not need to disconnect the pipes). This will expose
the impeller. Unscrew the impeller from the shaft to reach
the seal. Reassemble in reverse order. Clean the seals
and their sealing surfaces in the pump case. Lightly
lubricate the seals to aid in the assembly.
Do not run pump after it has
