Note: See Installation Wiring Diagrams for typical wiring hookups and control box identification.

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.

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 mm2) between pump and control box, run wire to separate junction box. Connect junction box to control box with a No. 10 (5 mm2) 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).

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.
