WARNING

IMPORTANT SAFETY INSTRUCTIONS

RULES FOR SAFE INSTALLATION AND OPERATION

1. Read these warnings and instructions carefully.
Failure to follow them could cause serious bodily
injury and/or property damage.

2. Follow all local electrical and safety codes as well
as the National Electrical Code (NEC) and the
Occupational Safety and Health Act (OSHA).

3. The power supply should be a separate circuit,
independent of all other circuits. Be sure it is
equipped with a fuse and disconnect box of ample
capacity.

4. For fire protection, the power supply should be free
of any building, preferably on a direct line from the
transformer. In the event of fire, the wires will not be
destroyed and the water supply not cut-off.

5. Always disconnect power source before performing
any work on or near the motor or its connected load.
If the power disconnect point is out-of-sight, lock it in
the open position and tag it to prevent unexpected
application of power. Failure to do so could result in
fatal electrical shock.

6. DO NOT handle pump with wet hands or when
standing in water as fatal electrical shock could occur.
Disconnect main power supply before handling pump
for any reason.

7. Shut off power source when voltage drops 10% below
the rated voltage of the motor.

8. Protect the power cable from coming in contact with
sharp objects, oil, grease, hot surfaces or chemicals.
DO NOT kink the power cable. If damaged replace
immediately.

9. NEVER leave the control box, fused disconnect
switch, or covers open (either partially or completely)
when not being worked on by a competent electrician
or repairman.

10. Always use caution when operating electrical controls
in damp areas. If possible, avoid all contact with
electrical equipment during thunderstorms or extreme
damp conditions.

11. Install all electrical equipment in protected area to
prevent mechanical damage which could produce
serious electrical shock and/or equipment failure.

12. Pump is designed to pump cold ground water that is
free of air or gases. Decreased pump performance
and life expectancy can occur if the ground water is
not cold (86°F/30°C) or contains air or gases.

13. Pump and controls must be securely and adequately
grounded as specified in section 250-43 item (A) of
the U.S.A. National Electric Code (NEC) and Section
26-954 Canadian Electrical Code. Failure to do so
could result in a fatal injury.

14. DO NOT use this pump to pump flammable liquids
such as gasoline, fuel oil, kerosene, etc. Failure to
follow the above warning could result in property
damage and/or personal injury.

The pump is intended for use in a well.
Motor frame must be connected to power supply ground or
fatal electrical shock may result. Do not use this pump in
swimming pools.

15. Capacitors inside CP WATER

Subdrive controllers can still hold a lethal voltage
even after power has been removed. Allow 10 minutes
for dangerous internal voltage to discharge before
operating the unit.

16. Use of this unit with motors from

other manufacturers may result in damage to both
motor and electronics.

17. Do not use power factor correction

capacitor with the CP WATER Subdrive. Damage
will result to both motor and electronics.

NOTE: Pumps with the “CSA” mark are tested to UL
standard UL778 and certified to CSA standard C22.2 No.

READ THESE INSTRUCTIONS COMPLETELY BEFORE INSTALLATION

1. Check that the pump and motor mounting faces are
free from dirt.

2. Assemble the pump liquid end and motor together
so that mounting faces are in contact. Then tighten
assembly bolts evenly in a crossing pattern.

NOTE: Apply non-toxic FDA approved waterproof grease
such as Mobile 102, Texaco CYGNUS2661 or equivalent
to the coupling before assembly of pump coupling to
motor shaft. This will prolong spline life and prevent
abrasives from entering the spline area.

3. Check for free rotation of the pump and motor. A
slight drag is permissible.

4. Assemble the pump lead guard over the motor leads.

Do not cut or pinch lead wire during

assembly.

5. Assemble suction screen to pump mounting ring.

PRE-INSTALLATION

To save possible added expense and extra trips, observe
and complete as many as possible of the following
precautions and pre-installation procedures before going
to the job site or beginning the installation.

IMPORTANT PRECAUTIONS

1. Prior to installation, inspect the pump for damage.
Check for free pump and motor rotation. A slight drag
is permissible.

2. Check to make certain that the voltage of the motor
end and controls agree with the available phase
and voltage. Check power source. Check electrical
supply for correct fusing, correct wire size, and
adequate grounding and transformer size.

Since most submersible pump problems
are electrical, it is very important that all electrical work
be done properly. Therefore, all electrical hook-up work
or electrical service work should be done by a qualified
electrician or service man only!

3. Throughout installation, take care not to damage

the insulation of the electrical cable or motor leads.
Never support the weight of the unit by electrical cable
or motor leads.

4. Before the pump is installed, the well should be

pumped free of sand and other foreign matter with
a test pump. The warranty is void if it is used to

clean the well.

MAJOR WELL COMPONENTS

1. Submersible Pump — A submersible pump is a multi­stage centrifugal. Each stage consists of an impeller
and diffuser. Water pressure increases in equal
amounts as it passes from stage to stage. The more
stages, the higher the pressure the pump will develop.

2. Submersible Motor — The submersible motor is
powered by three phase electricity. Make sure the
motor is designed for three phase operation.

3. Subdrive Controller — Subdrive is designed for use
in residential and light commercial applications with a
3-phase submersible motor using single-phase input.

Motor Design Designation

Subdrive 75 Controller 1-1/2 HP

Subdrive 100 Controller 2 HP

Subdrive 150 Controller 3 HP

This variable speed controller can be used to provide

constant pressure delivery over a wide range of
settings (25 to 80 PSI). Factory preset is 50 PSI.

4. The Well — The well should be sand free and have a
sufficient flow of water to supply the pump. Clear well
of sand and any other foreign matter with a test pump
before installing the new submersible pump.

Using the submersible pump to clean the

well will void the warranty.

a. When drilling a new well in an area where sand is

a problem, a sand screen should be installed to
protect the pump and motor.

b. The well should be straight so damage during

installation does not occur to the pump or motor by
becoming lodged in a crooked well casing.

c. The complete pump and motor should be

submerged at least ten feet below the draw
down level of the well, and the motor should be a
minimum of ten feet off the bottom of the well.

5. The Piping — Install the pump with pipe of the same
diameter as the discharge port of the pump or larger.

NOTE: Use of pipe smaller than the discharge port of the
pump will restrict the capacity of the pump and lower its
operating performance.

6. Check Valve — A check valve is required on all
submersible installations. This valve maintains water
within the pipe when the pump is not running. A line
check should be installed within 25 feet of the pump
and below the draw down level of the water supply.

a. For well depths exceeding 200 feet, it is suggested

that an additional check valve be installed every
125 feet.

b. An additional check valve should be installed in the

horizontal line between the well top and the pressure
tank.

Make certain that the check valve is

pointing in the right direction, arrow pointing towards the
tank.

7. Torque Arrester — To center the pump as it is
being lowered into the well, a torque arrester is
recommended.

8. Pressure Tank — Any change to operating system
pressure will require that the precharge in the tank be
modified to 70% of that pressure.

9. Pressure Relief Valve — The pressure relief valve and
the discharge outlet need a flow rating which exceeds
the flow capacity of the installation at the relief
pressure. When located in an area where a water leak
or relief valve blow-off may damage property, connect
an adequate drain line to the pressure relief valve.
Run the line to a suitable drain or to an area where
the water will not damage property.

Not providing an adequate relief valve
can cause extreme overpressure which could result in
personal and/or property damage. It is recommended that
you manually activate the valve monthly to keep it in good

working condition.

10. Pitless Adapter — A pitless adapter provides below

grade discharge while maintaining above grade
access to the well. Placed below the frost line they
are frost proof and also prevent well contamination by
providing a water tight seal between the vertical drop
pipe and the horizontal service pipe connection.

11. Well Seal — On well seal installations the piping in

the well projects above the well and is connected
above ground to the system piping by means of a tee
or elbow. Since the plumbing is above ground, it must
be protected from freezing.

12. Submersible Cable — Submersible power cable must

be UL listed for submersible pump application. Selecting
the proper cable size is important. Undersized cable
results in a too low voltage supply to the pump motor
