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.

DANGER

CAUTION

WARNING

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

Important notice: Read safety instructions before

proceeding with any wiring.

WARNING

DANGER

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.

FLOW SLEEVE

IMPORTANT

This manual is intended ONLY for use by

professionals familiar with NEC (National

Electric Codes) electrical codes and

hydraulic and safety procedures of pump

installations.
