ELECTRICAL
• Disconnect power at electrical panel before
WARNING
making any electrical connections.
• Supply voltage must be +/- 10% of motor
nameplate voltage. Low or excessive
voltage can damage the motor and will
void the warranty.
• If possible, connect pump to dedicated
branch circuit with no other appliances on it.
• Connect motor ground wire before connecting power
supply wires.
• Do not operate pump unless pump is grounded.
NOTICE: Read and follow all safety 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.
CAUTION! If you are not sure of proper electrical
connections, consult a licensed electrician.
Step 1:
Remove motor access cover at back of motor.
Step 2:
Feed the grounding wire (green or bare copper) through
the electrical conduit port in the side of the motor. First
connect the ground wire then connect the power supply
wires. Attach the grounding wire to the motor ground
screw (green). Secure wires to prevent electrical shorts.
Step 3:
Adjust the voltage switch to match the power supply.
Dual voltage pump motors come factory pre-set for
230 volts. Convert to 115 volts by sliding the "Easy Flip"
switch to the 115 volt setting.
Step 4:
Connect the incoming power supply wires to the motor
terminal.
Step 5:
Replace and secure motor cover.
NOTE: Single phase motors rotate counter-clockwise
only (when facing suction port) and cannot be reversed.

PRIMING AND START UP
WARNING
NEVER run pump dry. Fill pump with
WARNING
water before starting pump. Operating pump dry may cause
damage to pump and will void warranty.
WARNING
WARNING
NEVER run pump against a closed
discharge. This may cause hazardous pressure and risk of
explosion.
Step 1:
Remove priming port plug from pump.

DRAIN PLUG
Step 2:
Open discharge valves and any hoses on discharge side
of pump.
Step 3:
Fill pump with water through the priming port on
top of pump. Allow trapped air to escape for a few
minutes, then add more water until full.
Step 4:
Replace priming port plug and tighten with wrench,
using tefl on tape on pipe threads.
Step 5:
Start the pump. A properly primed pump should
discharge water without air at a consistent pressure. If
the pump does not produce water after a few minutes,
stop the pump, release all pressure, remove priming port
plug, add more water, replace plug, and try again. Make
sure that a foot valve is properly installed on the suction
pipe. (See "Suction Port Connection" in PLUMBING
section.)
