INSTALLATION & OPERATION
MOTOR GROUNDING INSTRUCTIONS
Failure to ground this unit properly may result in
severe electrical shock.
1.
If the means of connection to the supply-connection box is
other than grounded metal conduit, ground the pump motor
back to the service by connecting a copper conductor, at
least the size of the circuit conductors supplying the pump
motor, to the grounding screw provided on rib underneath
wiring compartment cover. N.E.C. requires pump motor be
grounded at installation.
2.
Voltage of power supply must match the voltage of the
pump. The 2 hp is factory preset to 230V and will not
operate at any other voltage.
However, the 3/4 hp, 1 hp and 1-1/2 hp are dual voltage
motors. They are preset to 230 volts, but may be converted
to 115 volts (Figure 1).
3.
Convert Dial Type by turning dial to select 115 volts. Insert
tool in slot to turn dial. If motor is converted to 115V, an
electrician should insure electrical and power leads can
handle the higher amps.

PRIOR TO INSTALLATION
Cover well to prevent foreign matter from contaminating the
well or later damaging the pump during operation. Test well
water for purity. Chlorination may be necessary. Check local
health department for proper testing and recommendations.

FLUSHING
Hand pump new wells until clear. Pumping sand or other
sediment will seriously damage the pump and void warranty.
Periodic flushing will remove internal pump sediment buildup. To
flush:

(For cased shallow wells only)
Tie a small but heavy weight to the end of a piece of string.
Lower the weight into the well until it reaches the bottom. Take
up the slack and mark the string at ground level.

PIPING
All piping must be clean and free of all foreign matter to prevent
clogging. Plastic PVC pipe is shown in the illustrations, but
galvanized steel pipe may be used if desired.
All joints and connections in the well assembly must be airtight.
Even a pinhole leak will prevent the proper operation of the
pump (this is the most common problem). Use thread compound
on all threaded joints unless specified otherwise.
Remove 1-1/2" plug from top of discharge tee, or remove
piping if no discharge tee has been installed.
Remove 1/4" plug from the lower front of pump.
Pour water into top of pump until water flowing from lower
front of pump is clear.
Scrape out any stubborn debris from the lower front
opening with a wire or pipe cleaner.
Reinstall pipes and plugs and re-prime before returning
pump to service.
Running the pump without discharge water
flow will cause serious damage inside the pump due to heat
buildup.
DETERMINE OPERATING DEPTH
Tie a small but heavy weight to the end of a length of string.
Lower into the well until the string goes slack.
Take up slack until string is taut and mark the string at
ground level.
Pull string out of well and measure length from mark to
heavy weight. This is the water depth. A shallow well pump
operates at 25 feet or less water depth. A deep well pump
operates at 70 feet or less water depth.
