READ AND FOLLOW
SAFETY INSTRUCTIONS!
This is the safety alert symbol. When you see this
symbol on your pump or in this manual, look for one of
the following signal words and be alert to the potential for
personal injury.
warns about hazards that will cause serious
personal injury, death or major property damage if ignored.
warns about hazards that can cause serious
personal injury, death or major property damage if ignored.
warns about hazards that will or can cause
minor personal injury or property damage if ignored.
The word NOTICE indicates special instructions which are
important but not related to hazards.
To avoid risk of serious bodily injury and property damage,
read safety instructions carefully before installing pump.
Hazardous voltage. Can shock, burn, or
cause death. Ground pump before connecting to power supply.
Pump is non-submersible. Keep motor dry at all
times. Do not wash motor. Do not immerse. Protect
motor from wet weather.
Burn Hazard. Do not touch an operating
motor. Modern motors are designed to operate at high
temperatures. To avoid burns when servicing pump, allow it to
cool for 20 minutes after shut-down before handling.
Follow local and/or national plumbing and electrical codes
when installing.
Hazardous Pressure. DO NOT run the pump
with discharge shutoff, as pipe may burst or pump may be
damaged due to high temperatures.
Do not allow pump or any system component to freeze. To do
so may damage system and will void warranty.
Risk of electric shock. To avoid fatal shocks,
proceed as follows if pump needs servicing.
A. Disconnect power to pump before servicing. After
power is shut off, let pump cool for 20 minutes before
attempting to work on it.
B. Take extreme care when changing fuses. To reduce
chance of fatal electrical shocks, DO NOT stand in water
or put your finger in the fuse socket.
C. Ground electrical outlet box.
D. Use only Ground Fault Circuit Interrupter (GFCI)
protected, grounded, circuit with pump.
Never run pump dry. Running pump dry can damage internal
parts, overheat pump (which can cause burns to people
handling or servicing pump), and will void warranty.
Do not pump chemicals or corrosive liquids with pump.
Hazardous Pressure.
A. High pressure discharge stream is dangerous. To
avoid injury, DO NOT stand in front of the discharge
stream.
B. BE SURE that the pump suction pipe pressure plus the
pump discharge pressure does not exceed the
pressure rating of pipe and fittings.
C. Pump body may explode if pressures exceed rated
limits. Maximum inlet pressure is 80 PSI. Maximum
discharge pressure is 315 PSI. Warranty is void if these
pressure limits are exceeded.
LUBRICATION
The internal running surfaces of the pump and seals require
water lubrication for good, consistent operation. Allowing
pump to run dry will severely damage pump and seals.
It is not necessary to lubricate pump or motor. The motor is
equipped with sealed ball bearings, lubricated for the life of the
bearing. The mechanical shaft seal in the pump is self-
lubricating and requires no adjustment. Disassemble pump to
replace seal.
INSTALLATION
Use a 3/4” or 1” pipe or heavy-duty non-collapsible hose for
suction line.
OPERATION
NOTICE: Observe the following precautions when operating
the pump:
1. Keep the motor dry!
2. Hazardous pressure. Do not run the
pump with discharge shutoff, as pipe may burst or pump
may be damaged due to high pressure.
3. Do not run pump dry; dry running may damage the seal.
ELECTRICAL
Ground motor before connecting to electrical power
supply. Failure to ground motor can cause severe
or fatal electrical shock hazard.
Explosion hazard. Do not ground to a gas supply
line.
To avoid dangerous or fatal electrical shock, turn
OFF power to motor before working on electrical
connections.
Supply voltage must be within ±10% of nameplate
voltage. Incorrect voltage can cause fire or serious
damage to motor and voids warranty. If in doubt consult a
licensed electrician.
Use wire size specified in Wiring Chart (Table I). If
possible, connect pump to a separate branch
circuit with no other appliances on it.
Wire motor according to diagram on motor
nameplate.

WIRING CONNECTIONS
NOTICE: Clamp the power cable to prevent strain on the
terminal screws.
Refer to motor wiring diagram on pump motor for proper motor
wiring connection.
1. Install, ground, wire and maintain this pump in
compliance with the National Electrical Code (NEC) or the
Canadian Electrical Code (CEC) and with all local codes
and ordinances that apply. Consult your local building
inspector for local information.
2. Make sure that the voltage, frequency and phase (single
phase or three phase) of the power supply agree with that
stamped on the motor nameplate. If in doubt, check with
the power company.
3. Some models are equipped with three phase motors.
Three phase motors require magnetic starters and can
run in either direction, depending on how they are
connected to the power supply.
To Check For Proper Rotation – 3 Phase Motors
NOTICE: Some models are equipped with three phase motors.
Three phase motors require magnetic starters and can run in
either direction, depending on how they are connected to the
power supply.
Risk of electrical shock.
1. Be sure power is disconnected to motor when working on
electrical connections.
2. Remove the cap over the motor shaft. Momentarily start
pump. If hookup is correct, the shaft will rotate clockwise.
3. If rotation is not clockwise, reverse any two leads to the
starter. The rotation will now be correct.
GROUNDING THE MOTOR
Ground the pump permanently using a wire of size and type
specified by local or National Electrical Code.
MAINTENANCE
