Safety Warnings
SAFETY WARNINGS
TO AVOID SERIOUS OR FATAL PERSONAL INJURY OR
MAJOR PROPERTY DAMAGE, READ AND FOLLOW ALL
SAFETY INSTRUCTIONS IN MANUAL AND ON PUMP.
THIS MANUAL IS INTENDED TO ASSIST IN THE
INSTALLATION AND OPERATION OF THIS UNIT AND
MUST BE KEPT WITH THE PUMP.
This is a SAFETY ALERT SYMBOL.
When you see this symbol on the pump
or in the manual, look for one of the
following signal words and be alert to the
potential for personal injury or property
damage.
Warns of hazards that WILL cause
serious personal injury, death or major
property damage.
Warns of hazards that CAN cause serious
personal injury, death or major property
damage.
Warns of hazards that CAN cause per-
sonal injury or property damage.
NOTICE: INDICATES SPECIAL INSTRUCTIONS
WHICH ARE VERY IMPORTANT AND
MUST BE FOLLOWED.
THOROUGHLY REVIEW ALL INSTRUCTIONS AND
WARNINGS PRIOR TO PERFORMING ANY WORK
ON THIS PUMP.
MAINTAIN ALL SAFETY DECALS.

SAFETY WARNINGS
All electrical work must be performed by
a qualified technician. Always follow the
National Electrical Code (NEC), or the Canadian Electri-
cal Code, as well as all local, state and provincial codes.
Code questions should be directed to your local electrical
inspector. Failure to follow electrical codes and OSHA safety
standards may result in personal injury or equipment dam-
age. Failure to follow manufacturer’s installation instructions
may result in electrical shock, fire hazard, personal injury or
death, damaged equipment, provide unsatisfactory perfor-
mance, and may void manufacturer’s warranty.
Standard units are not designed for use in
swimming pools, open bodies of water,
hazardous liquids, or where flammable gases exist. Well must
be vented per local codes. See specific pump catalog bulletins
or pump nameplate for all agency Listings.
Disconnect and lockout electrical power
before installing or servicing any electri-
cal equipment. Many pumps are equipped with automatic
thermal overload protection which may allow an overheated
pump to restart unexpectedly.
Never over pressurize the tank, piping or
system to a pressure higher than the tank's
maximum pressure rating. This will damage the tank, voids
the warranty and may create a serious hazard.
Protect tanks from excessive moisture and
spray as it will cause the tank to rust and
may create a hazard. See tank warning labels and IOM for
more information.
Do not lift, carry or hang pump by the
electrical cables. Damage to the electri-
cal cables can cause shock, burns or death.
Use only stranded copper wire to pump/
motor and ground. The ground wire must
be at least as large as the power supply wires. Wires should
be color coded for ease of maintenance and troubleshooting.

WARNING
Install wire and ground according to
the National Electrical Code (NEC), or
the Canadian Electrical Code, as well as all local, state and
provincial codes.
Install an all leg disconnect switch where
required by code.
The electrical supply voltage and phase
must match all equipment requirements.
Incorrect voltage or phase can cause fire, motor and control
damage, and voids the warranty.
All splices must be waterproof. If using
splice kits follow manufacturer’s
instructions.
Select the correct type and NEMA grade
junction box for the application and
location. The junction box must insure dry, safe wiring
connections.
All motors require a minimum
5' submergence for proper refill check
valve operation.
Failure to permanently ground the pump,
motor and controls before connecting to
power can cause shock, burns or death.
All three phase (3Ø) controls for sub-
mersible pumps must provide Class 10,
quick-trip, overload protection.
4" motors ≥2 HP require a minimum
flow rate of .25 ft/sec. or 7.62 cm/sec.
past the motor for proper motor cooling. The following are
the minimum flows in GPM per well diameter required for
cooling: 1.2 GPM/4", 7 GPM/5", 13 GPM/6", 20 GPM/7",
30 GPM/8" or 50 GPM in a 10" well.
Pumps ≥2 HP installed in large tanks
should be installed in a flow inducer
sleeve to create the needed cooling flow or velocity past the
motor.

RULE OF THUMB
1. Use same size or larger
pipe as discharge on pump.
2. Always use a check valve
for every 200 ft. of vertical pipe.
➀On installations with a pitless adapter
the top check valve should be below
the pitless, not at the tank, as the
discharge line should be pressurized
back to the pitless.
➁On installations with well seals or well
pits it is allowable to locate the top
check valve near the tank.

TYPICAL SYSTEM
Motor Cooling, Temperature
and Time Ratings
All 4 inch CentriPro motors may be
operated continuously in water up to
86º F. Optimum service life will be
attained by maintaining a minimum
ow rate past the motor of .25 feet per
second. Use a Flow Sleeve if velocity
is below the .25'/sec, if the well is top
feeding or when the pump is used in a
large body of water or large tank.
Six (6) inch canned design motors from
5 – 40 HP will operate in water up to
95º F (35º C), without any de-rating of
horsepower, with a minimum ow rate of
.5 ft./sec. past the motor. 6" – 50 HP and
all 8" – 10" motors can operate in 77º F
(25º C) water with .5'/sec velocity past
the motor.
One way to make a ow sleeve is to install a well seal
above the pump discharge and slip a piece of casing
over the pump and afx it to the well seal. Drill three
holes at 120º intervals on the lower section of the casing
and insert (3) screws and nuts through the casing, just
touching the motor. Tighten the nuts out against the
casing. Insure that the screws do not protrude out too
far as you don’t want them catching on well joints.
Pump Cooling and Lubrication
In addition to motor cooling, another reason to
maintain minimum ow rates is pump lubrication. All
manufacturers’, either on curves or in selection charts,
show minimum ows. This insures that rotating pump
parts are properly lubricated to prolong service life and
reduce friction. A dead headed pump will super heat
water very quickly, and hot water has no lubricity.
