Location Of Unit

Locate the pump as near the liquid source as possible,
using a short, direct suction pipe. Keep the static suction
lift (vertical distance between the center line of the pump
and the liquid level) to a minimum. Mount the pump
on a solid, level foundation, which provides a rigid and
vibration-free support. It should be located where the
unit is readily accessible for service and maintenance.
The pump should be protected against flooding and
excessive moisture.

Piping

Both suction and discharge piping should be
independently supported at a point near the pump to
avoid strains being placed on the pump. Start all piping
at pump to avoid strains left by a gap at last connection.

Suction Piping

The suction pipe must be kept free of leaks. The suction
pipe must have a gradual slope upward to the pump.
Avoid any fittings which may cause an air trap. On units
that have a suction fitting, a check valve is a built-in
feature and no foot valve is required.

Discharge Piping

A gate valve and union should be installed in the
discharge line. For removal of the pump for service, close
the gate valve, and disconnect at union.

Electrical Information

Hazardous voltage. Disconnect power at

service panel be fore connecting motor. Single phase
motors come factory wired for 230 volt operation. Do
not alter wiring in single phase motors. Match motor
voltage to power supply voltage. Do not connect three
phase motors to single phase power supply or single
phase motors to three phase power supply.
• Ground motor before connecting to electrical

power supply.

• Failure to ground motor can cause severe or fatal

electrical shock 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 seriously
damage motor and voids warranty. If in doubt
consult a licensed electrician.

• Use wire size specified in Wiring Chart. If possible,

connect pump to a separate branch circuit with no
other appliances on it.

Wiring

1. Install, ground, wire and maintain this pump in

ac cordance with your local electrical code and all
other codes and ordinances that apply. Consult your
local building inspector for local code information.

2. Ground the pump permanently using a wire of size

and type specified by local or National Electrical
Code. Do not ground to a gas supply line.

3. Connect ground wire first. Connect to ground

first, then to green grounding terminal provided
(identified as GRD or ). Make ground connection
to this terminal. Do not connect motor to electrical
power supply until unit is permanently grounded;
otherwise serious or fatal electrical shock hazard
may be caused.

4. For best ground connection, connect to a grounded

lead in the service panel or to a metal underground
water pipe or well casing at least 10 ft. long. If
plastic pipe or insulated fittings are used, run ground
wire directly to the metal well casing or use ground
electrode furnished by the power company.

Hazardous voltage. Before using pump, check

your motor nameplate for voltage. Your electric supply
voltage and the stamped nameplate voltage must agree.
Motors stamped 200 volts only or 230 volts only, must
be used with that voltage only. Motors stamped with
two voltages (for example 230/460 volts), may be used
with either supply voltage. For these motors check
connections against wiring diagram on motor nameplate
and make any changes necessary to agree with your
supply voltage. If in doubt, call a licensed electrician.
Incorrect voltage will cause serious damage to the motor.
Some models are equipped with three phase motors.
Three phase motors require magnetic starters.
To check motors for proper rotation: The shaft can be
seen through the motor - pump adapter bracket. A mark
can be made on the shaft to make it easier to notice
rotation. Jog the motor (start it briefly) and note the
rotation. It should rotate clockwise when viewed from
the motor-end. If rotation is not clockwise, see motor
nameplate for hookup information. BE SURE power is off
to the motor when working on electrical connections.
