in permanent damage to the motor. All
electrical wiring should meet the local
electrical code.
NOTICE
READ AND FOLLOW ALL INSTRUCTIONS!
Pump connection must comply with National Electric
Code (NEC) or Canadian Electric Code (CEC), and all
applicable local codes.
All dual voltage units come factory preset for 230
volts. (Figure 3)
Disconnect power at electrical panel before making any
electrical connections.
Supply voltage must be +/- 10% of motor nameplate
voltage. Low or high voltage can damage the motor and
will void the warranty.
If possible, connect pump to dedicated branch circuit with
no other appliances on it.
Do not operate pump unless pump is grounded
DUAL VOLTAGE ADJUSTMENT
NOTE: To change the motor voltage(Figure 4) unplug the
dual voltage connector on the motor and reconnect it in
the position required to match the available electrical
system. The motor can be set for 115 volts or 230 volts.

Voltage setting of the motor can be determined by looking
at the alignment of the arrow on the plug and the arrow
on the motor terminal board (located under the motor's
end cover). Any questions as to which voltage setting is
required for proper motor and pump operation in your
system should be directed to an electrical professional.
The factory preset is 230 volts.

Check Valve
NOTICE: Check motor terminal cover or nameplate for wiring
instructions. The essential pump motor facts are as follows:
1. 3450 RPM
2. Single Phase
3. Dual Voltage, 115/230
4. 1/2, 3/4, 1, 1-1/2, and 2 Horsepower motors are wired
for 230 volts as a factory standard.
Note that all wiring is subject to official inspection and must
conform to the local electrical code. Install a circuit breaker or
fused disconnect switch near the pump. Connect the
incoming power wires to the LINE terminals and the green or
bare wire to the ground screw, then ground the entire unit.
OPERATION
PRIMING (FIGURE 4)
The motor should not be started before pump is primed.
To prime the pump, fill the pump case and suction
pipe completely with water. Install discharge and
suction fittings securely to ensure there are no system
leaks. Use Priming Port.
Close all system outlets, then slightly crack one system outlet
to allow for excess air to bleed from the plumbing system.
Start the pump. Water will start pumping in a few minutes; the
time is dependent on the distance to the water source. 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 system outlets slowly and let
pump operate until water runs clear. No further priming
should be necessary unless: the pump is drained for repair or
storage, there is a leak in the suction line plumbing, or there
is a failure of the system's foot or check valves.
Note: Three-phase units are designed to run in a
counter clockwise manner when viewed from the pump
end. Improper rotation can result in low performance or
hydraulic failure.
