WIRING INSTALLATION

Single Phase, 3 Wire

Hazardous voltage! The

electrical system in this pump

CAN cause electrical shock

and death. Permanently ground control

box, metal plumbing, and motor frame

in accordance with national and local

codes. Use copper grounding wire with

a diameter no less than wires carrying

current to motor.

1. At well head, connect grounding

wire to grounding terminal.

Grounding system must meet

all applicable national and

local electrical codes. For more

information, contact local code

officials.

2. Permanently close all unused

openings in this and other

equipment. Disconnect power

before working on or around control

box, pipes, cable, pump, or motor.

3. Install control box vertically on wall

with top side up.

NOTE: Three-wire pumps have three

power supply wires (Red/Black/Yellow)

and one ground wire (Green). When

operated without a control box, three-

wire pumps will not operate properly

and will likely cause motor to burn out.

12. Use wire of adequate size to

minimize voltage drop at the motor.

13. Pipe joint compound can cause

cracking in plastics. Use only

plumbers seal tape when sealing

threaded joints in plastic pipe

or when connecting pipe to

thermoplastic pumps.

Do NOT handle

pump or pump

motor with wet hands, when standing

on a wet or damp surface or when

standing in water. Fatal electrical shock

COULD occur!

Pump motor is

equipped with an

automatic resetting thermal protector

and MAY restart unexpectedly. Protector

tripping is an indication of motor

overloading because of operating

pump at low heads (low discharge

restriction), excessively high or low

voltage, inadequate wiring, incorrect

motor connections, inadequate cooling

or defective motor or pump.

Pre-Installation

1. Inspect pump and motor for delivery

damage.

2. Before installing pump, remove

all fine sand particles and foreign

matter. See Initial Startup section (on

page 4) for more information.

3. Install pump at least 15-20 feet

below the lowest water level

reached with pump running (lowest

drawn-down water level), and at

least 5 feet above bottom of well.

To maximize performance, pump should

process only cold water that is clear and

free of entrained air.

Warranty is void if (1) system pumps

excessive sand resulting in early

pump wear, (2) water is corrosive, (3)

entrained gas or air causes reduced flow

and cavitation, or (4) pump operates

with discharge valve closed, resulting in

serious damage.

Electrical System

WIRING/GROUNDING

Hazardous voltage! The

electrical system in this

pump can cause electrical

shock and death. Permanently ground

pump, motor and control box before

connecting to electrical supply. Ground

pump and motor in accordance with all

codes and ordinances that apply. Use

copper grounding wire with a diameter

no less than wires carrying current to

motor.

1. Permanently ground pump, motor

and control box before connecting

power cable to power supply.

Connect ground wire to approved

ground first, and then connect to

equipment being installed.

2. Motor is supplied with copper

grounding wire. Splice wire to

copper conductor that matches wire

size shown in Table 3, on page 3. See

Wire Splicing under Installation, on

page 4.

Do NOT ground to

gas supply line.

Fire, explosion,

and death or serious injury COULD

result.

Fire and electrical

shock hazard! If

using a power

supply wire larger than No. 10 (5 mm

)

between pump and control box, run

wire to separate junction box. Connect

junction box to control box with a No.

10 (5 mm

) wire.

For more information, contact your

local code officials.

WIRING CONNECTIONS

All wiring must meet National Electrical

Code requirements, as well as local code

requirements.

Use only copper wiring for connections

to pump and control box.

To prevent wire overheating and

excessive voltage drop at motor, use

wire size at least as large as size shown

in Table 3 on page 3 (based on HP and

length of wire run).
