california proposition 65 Warning
This product and related accessories contain
chemicals known to the State of California to cause cancer,
birth defects or other reproductive harm.
1. Before installing or servicing your pump, Be cerTain pump
power source is disconnected.
2. All installation and electrical wiring must adhere to state and
local codes and must be complete before priming the pump.
Check with appropriate community agencies, or contact
your local electrical and pump professionals.
3. Pump should be installed in a dry, convenient location close
to the well with ample space for installation and servicing
the well. A dry basement, pit, or utility room is an excellent
choice when allowed by law. The pump must be securely
fastened to a solid foundation. The pump should always
be mounted in a horizontal position on a level foundation.
Failure to properly secure the pump may result in failure of
the pump or piping and damage to the surrounding area.
4. call an elecTrician WHen in douBT. Pump motor
should be connected to a separate electrical circuit directly
from main switch. There must be a fuse box or circuit
breaker installed in this line. Plugging into existing outlets
may cause low voltage at motor, resulting in blown fuses,
tripping of motor overload, or burned-out motor. refer to
electrical diagrams for electrical connections.
5. It is mandatory that a permanent ground connection be
made from the pump motor to the grounding bar at the
service panel. Do not connect pump motor to a power supply
until permanently grounded. For maximum safety, ground
the pump motor to a circuit equipped with a fault interrupter
device.
6. Motor Grounding Instructions:
Reduced risk of electric shock during operation
of this pump requires the provision of acceptable grounding.
Failure to ground this unit properly may result
in severe electrical shock. 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. NOTE: N.E.C.
requires pump motor be grounded at installation.
7. Voltage of power supply must match the voltage of the
pump. The pump motor is dual voltage. It is factory preset
to 230V, but may be converted to 115 volts, see Figure 1.
If motor is converted to 115V, an electrician should insure
electrical and power leads can handle the higher amps.

8. During 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.
9. 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:
• 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 reprime before returning
pump to service.
10. The following may cause severe damage to pump and/or
piping and will void warranty:
• Failure to protect pump and piping against below freezing
temperature.
• Pumping chemicals or corrosive liquids.
• Pumping gasoline or other flammable liquids.
• Using extension cords.
• Using this pump in or near a swimming pool.
• Running the pump dry. Follow priming instructions.
• Discharge pressure not to exceed 100 psi.
• Torque for pump bolts is 15-20 ft.-lbs.
• Use of garden hose as discharge or suction line.
• Failure to securely fastened to a solid foundation.
11.
Running the pump without discharge water
flow will cause serious damage inside the pump due to heat
buildup.
