Installation
Before Installation
Inspect pump and motor for delivery damage.
Report any damage immediately to the shipping
carrier or to your dealer.
The well driller should thoroughly develop the
well (that is, pump out all fine sand and foreign
matter) before pump is installed.
Pump performance is based on pumping clear,
cold, liquid water.
Warranty is void in the following conditions:
• If pump has pumped excessive sand –
excessive sand can cause premature wear
to pump.
• If water is corrosive.
• If entrained gas or air are present in the water
being pumped – these can reduce flow and
cause cavitation which can damage pump.
• If pump has been operated with discharge
valve closed – severe internal damage
will result.
Install pump at least 15 to 20' (4.5 to 6 m) below
the lowest water level reached with pump
running (lowest draw-down water level), and at
least 5' (1.5m) above the bottom of the well.
Electrical Grounding Information
Risk of electric shock. Can shock,
burn or kill. To reduce the risk of electrical
shock during pump operation, ground and bond
the pump and motor as follows:
Ground pump and motor in accordance with
all codes and ordinances that apply. Use copper

ground wire at least as large as wires carrying
current to motor.
See Tables 1 and 2 for recommended fuses and
also see Cable Splicing. Motor is supplied with
copper ground wire. Splice to copper conductor
that matches motor wire size specified in
Table 3a or Table 3b.
Permanently ground pump, motor and control
box before connecting power cable to power
supply. Connect ground wire to approved
ground first, then connect to equipment
being installed.
Risk of explosion. Do not ground to
a gas supply line.
Risk of electric shock and fire.
If using a drop cable larger than AWG 10
(5.5mm²) [for example, AWG 8 (8.4mm²) wire]
between pump and control box, run drop cable
to a separate junction box. Connect junction
box to control box with AWG 10 (5.5mm²) wire.
For more information, contact your local
code officials.
Wiring Connections
All wiring must meet Canadian Electrical
Code or National Electrical Code and local
code requirements.
Use only copper wire for connections to pump
and control box.
To avoid over-heating wire and excessive
voltage drop at motor, be sure wire size is at
least as large as size listed in Table 3 for your
horsepower pump and length of wire run.
