Operating Instructions and Parts Manual
General Safety
Information
(Cont.)
and may restart unexpectedly. Protector
tripping is an indication of motor over-
loading because of operating pump at low
heads (low discharge restriction), exces-
sively high or low voltage, inadequate
wiring, incorrect motor connections or
defective motor or pump.
Pre-Installation
1. Inspect pump and motor for deliv-
ery damage. Report any damage
immediately to shipping carrier or
your dealer.
2. Before installing pump, remove all
fine sand particles and foreign mat-
ter. See Initial Startup section 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 oper-
ates with discharge valve closed, result-
ing in serious damage.
Electrical System
WIRING/GROUNDING
DANGER
!
Hazardous voltage! The elec-
trical system in this pump can
cause electrical shock and
death. Permanently ground pump,
motor and control box before connect-
ing to electrical outlet. 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 cop-
per conductor that matches wire
size shown in Table 3. See Cable
Splicing under Installation.
DANGER
!
Do not ground to
gas supply line.
Fire, explosion, and death or serious
injury could result.
DANGER
!
Fire and electrical
shock hazard! If
using a power supply wire larger than
No. 10 (5 mm
2
) between pump and con-
trol box, run wire to separate junction
box. Connect junction box to control
box with a No. 10 (5 mm
2
) wire.
For more information, contact your
local code officials.
WIRING CONNECTIONS
All wiring must meet National Electrical
Code or Canadian 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 exces-
sive voltage drop at motor, use wire
size at least as large as size shown in
Table 3 (based on HP and length of
wire run).

DANGER
!
Hazardous voltage! The elec-
trical 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 electri-
cal codes. For more information,
contact local code officials.
2. Permanently close all unused open-
ings 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.
NOTICE

trol box match (see Table 4). Failure to
do so will void warranty.
