Can shock, burn or cause
death. Permanently ground
pump, motor and
submersible motor control
before connecting power supply to motor.
5
Ground submersible motor in accordance with all codes
and ordinances that apply. Use copper ground wire at
least as large as wires carrying current to motor.
Motor is supplied with copper ground wire. Splice to cop-
per conductor that matches motor wire size specied in
Table 3. See “cable splicing” under installation.
Permanently ground pump, motor and submersible motor
control before connecting power cable to power supply.
Connect ground wire to approved ground rst, then con-
nect equipment being installed.
Do not ground to a gas supply line.
PLANNING INSTALLATION
Inspect the pump and motor for delivery damage. Report
any damage immediately to the shipping carrier or to your
dealer.
The well driller should pump out all ne sand and foreign
matter before the pump is installed. See the Initial Start-
Up section of this manual.
Pump performance is based on pumping clear, cold, liquid
water with no entrained air. Warranty is void in the follow-
ing conditions:
• If the pump has pumped excessive sand - excessive
sand can cause premature wear to pump.
GROUNDING THE PUMP
• If water is corrosive
• If entrained gas or air are present in water being
pumped - these can reduce ow and cause cavitation
which can damage pump.
• If pump has been operated with discharge valve
closed - severe internal damage will result.
Install the pump at least 15 to 20 ft. (4.5 to 6 m) below the
lowest water level reached with the pump running (lowest
draw-down water level), and at least 5 ft. (1.5M) above the
bottom of the well.
To avoid over-heating wire and excessive voltage drop at
motor, be sure wire size is sucient per NEC standards for
the pump horsepower and length of wire run.
NOTICE: See installation Wiring Diagrams for typical wiring
hookups and submersible motor control identication.
PRE-INSTALLATION
WIRING CONNECTIONS
All wiring must meet National Electrical Code or Canadian
Electrical Code and local code requirements.
Use only copper wire for connections to pump and sub-
mersible motor control.
