Operating Instructions and Parts Manual
PRE-INSTALLATION
WATER SUPPLIES
The water supplies illustrated in Figure 16 (on page 13) are possible
sources for water. These water supplies can be divided into two
categories:
SURFACE WATER
Water from a lake, storage tank, stream, pond and cistern. This water is
usually not fit for human consumption, but may be suitable for washing,
irrigation or other household uses.
GROUND WATER
Water found in the water bearing stratum at various levels beneath the
earth. Of all the fresh water found on earth only 3 percent is found on the
surface and 97 percent is underground.
WATER STORAGE
Tanks are required for these pumps to operate as designed.
TANKS - CONVENTIONAL STORAGE
The function of the tank is to store a quantity of water under pressure.
When full, the tank contains approximately 2/3 water and 1/3
compressed air. The compressed air forces the water out of the tank
when a faucet is opened. An air volume control automatically replaces air
lost or absorbed into the water. The usable water, or draw-down capacity,
of the tank is approximately 1/6 of the tanks total volume when operated
on a 30/50 pressure setting (Figure 1).
TANKS - PRE-CHARGED STORAGE
A pre-charged storage tank has a flexible bladder or diaphragm that acts
as a barrier between the compressed air and water. This barrier prevents
the air from being absorbed into the water and allows the water to be
acted on by compressed air at initially higher than atmospheric pressures
(pre-charged). More usable water is provided than with a conventional
type tank. Pre-charged tanks are specified in terms of a conventional
tank. For example, a 20 gallon pre-charged tank will have the same
usable water or draw-down capacity as a 40 gallon conventional tank,
but the tank is smaller in size (Figure 1). Pre-charged to be set at 28 PSI
with the tank empty of water.

INSTALLATION
LOCATION
Select a location as close to the water supply as possible. Be sure to
comply with any state or local codes regarding the placement of the
pump. The equipment must be protected from the elements or voids
warranty. A basement or heated pump house is a good location. Make
sure the pump has proper ventilation. The temperature surrounding the
pump is not to exceed 100° F (38°C) or nuisance tripping of the motor
overload may occur.
This pump is designed for indoor installation
only, unless housed and protected from the elements. Failure to install
indoors will significantly increase the risk of injury or death from
electrical shock.
Cette pompe est conçue pour être installée à
l’intérieur sauf si elle est abritée et protégée contre les intempéries.
Ne pas l’installer à l’abri dans un local augmente considérablement le
risque de blessure ou de mort par électrocution.
WELLS
A new well should be pumped clear of sand before installing the
pump. Sand will damage the pumping parts and seal. The draw-
down level of the well should not exceed the maximum rated depth
for the pump. The capacity of the pump will be reduced and a loss
of prime may occur.
PIPING
Inlet piping may be copper, steel, or rigid PVC plastic.
Flexible pipe is prohibited on suction pipe (inlet
pipe).
MISE EN GARDE Un tuyau flexible est interdit sur le tuyau
d’aspiration (tuyau d’entrée).
The pipe must be clean and free of rust or scale. Use a pipe joint
compound on the male threads of the metal pipe. Plumber’s seal tape
should be used with plastic threads. All connections must be air tight to
insure normal operation.
Slope all inlet piping upwards towards the pump to prevent trapping air.
Unions or hose couplings can be installed near pump to facilitate removal
for servicing or storage. A rubber hose installed between the water
system and the house piping will reduce the noise transmitted to the
house.
Plastic pipe can be used on all installations except 2 in. deep well jet.
The 2 in. deep well jet requires 1-1/4 in. galvanized steel pipe and special
machined couplings (1-13/16 in. O. D.).
The galvanized steel pipe and the couplings restrict the flow of return
water back to the jet unless the couplings are machined.

INSTALLATION (CONTINUED)
PRESSURE SWITCH
The pressure switch provides for automatic operation. The pump starts
when pressure drops to a cut-in setting. The pump stops when pressure
reaches a cut-out setting. The pressure switch preset and is NOT
adjustable.
PIPE SIZES
Long horizontal pipe runs and an abundance of fittings and couplers
decrease water pressure due to friction loss. See Chart 1, on page 5, to
determine the proper pipe size.
SHALLOW WELL INSTALLATION
A shallow well jet assembly can be used with the deep well pump when
the pump is located a maximum of 25 ft vertically above the water level
(see converting to shallow well pump on page 7). Shallow well installations
have only one pipe between the pump and water supply (Figure 2).
DRILLED WELL (FIGURE 16, PAGE 13)
1. Install a foot valve on the first section of pipe (Figure 2, Illustration A).
2. Lower the pipe into the well.
3. Add pipe until the foot valve is 5 feet below the lowest anticipated
water level.
The foot valve must be at least 18 in. from the
bottom of the well or sand or sediment could be drawn into the system.
MISE EN GARDE Le clapet de pied doit au moins être à 45,7
cm (18po) du fond du puits, sinon du sable ou des sédiments pourraient
être aspirés dans le système.
4. After proper depth is reached, install a well seal or pitless adapter to
support pipe and prevent surface. water and other contaminants
from entering well.
5. Slope the horizontal pipe upward toward the pump to eliminate
trapping air. Sloping the pipe will also aid in priming the pump.
DRIVEN WELL (FIGURE 16, PAGE 13)
• Drive the point several feet below the water table.
NOTE: A packer type foot valve can be installed in the well (Figure 2,
Illustration B). This type of foot valve allows the piping to be filled with
water when priming and makes the inlet pipe much easier to test for
leaks. Follow the manufacturer’s instructions when installing the packer
type foot valve.
As an alternative, an in-line check valve can be used with a driven well
(Figure 2, Illustration C). The pipe between the check valve and the water
level will always be under a vacuum.
Leaking joints or couplings will allow air to leak into the pipe and cause
abnormal pump operation. Make sure to use pipe joint compound on all
male pipe threads.
DUG WELL, CISTERN, LAKE AND SPRING INSTALLATION
(FIGURE 16, PAGE 13)
• Install a foot valve on inlet pipe and lower into water.
The foot valve must be at least 18 in. from the
bottom of the well or sand or sediment could be drawn into the system.
MISE EN GARDE Le clapet de pied doit au moins être à 45,7
cm (18po) du fond du puits, sinon du sable ou des sédiments pourraient
être aspirés dans le système.
NOTE: When a lake is used as a water supply, make sure the inlet pipe
is deep enough to be submerged at all times.
Slope the horizontal piping upward toward the pump to prevent trapping
air. The pipe must be removed during winter months or protected against
freezing.
Protect the pipe from damage from swimmers and boats.
Install a screen around the inlet pipe to prevent
the entrapment of swimmers, wildlife and debris.

DRILLED WELL (2 IN.) WITH SINGLE PIPE PACKER (FIGURES 16
AND 4)
NOTE: Single pipe packer jets rely on the space between single pipe and
inside of well casing for return water to operate jet. Two inch installations
must use 1-1/4 in. galvanized steel pipe with special turned couplings (1-
13/16 in. O.D.) to avoid restricting flow of return water back to jet.
1. Assemble the foot valve and packer to the jet body.
2. Lubricate the rubber cups with petroleum jelly.
3. Attach the first section of pipe and lower jet into well.
4. Add pipe until the jet is positioned 5 - 15 feet below the lowest
anticipated water level. The jet should never be closer than 5 feet
from the bottom of the well or sand and sediment may be drawn
into the system.
5. With the jet in position, fill the pipes with water to make sure the
rubber cups are sealed against inside of the well casing. It may be
necessary to move the jet up and down to seat the cups.
6. Install the casing adapter and the horizontal pipes.

Select the proper size wire and fuse. Time delay fuses are recommended
over standard fuses for motor circuit protection. All pump motors have
built-in automatic overload protection that will prevent damage to the
motor due to overheating. If wire run is a short distance, a cord/plug
assembly may be used as long as it meets the minimum wire gage size
called out in Chart 2.

Do not connect to electric power supply until
unit is permanently grounded. Connect ground wire to approved ground
then connect terminal provided.
Ne pas connecter à l’alimentation électrique
tant que l’unité n’est pas mise à la terre en permanence. Brancher le fil
de mise à la terre à la masse approuvée puis raccorder la borne fournie.
A metal underground water pipe or well casing at least 10 feet long
makes the best ground electrode. If plastic pipe or insulated fittings
are used, run a wire directly to the metal well casing or use a ground
electrode furnished by the power company.
There is only one proper ground terminal on the unit. The terminal is
located under the pressure switch cover, is painted green and is identified
as GRD. The ground connection must be made at this terminal (Figure 9).
The ground conductor must not be smaller than the circuit conductors
supplying the motor.
The voltage of power supply must match the voltage of the pump.
The unit has dual voltage motors preset at the factory to 115 volts. The
motors can be converted to 230 volts by changing the voltage selector to
the desired voltage (Figure 10). Disconnect power, use needle nose pliers
to pull the selector out approximately 1/4 in., point too, and then reinsert
in correct position.
Disconnect power and release all pressure from
the system before attempting to install, service, relocate or perform any
maintenance.

MISE EN GARDE
Protéger la pompe du gel pendant l’hiver.
DRAINING THE PUMP
Drain openings are provided on all models. To drain the pump:
1. Remove drain plug and prime plug to vent the system.
2. Drain all piping to a point below the freeze line.
DRAINING THE TANK
Conventional tanks can be drained by opening an outlet at the lowest
point in the system. Remove plug or the air volume control to vent the
tank.
Pre-charged tanks force virtually all the water from the tank when system
pressure is released. No draining is necessary.
RESTARTING PUMP
If the pump has been serviced, drained or has not been used for some
time, be sure there is water in the pump housing (volute) and the piping
to the well. There must be water in the pump housing (volute) at all times
when the pump is running to avoid internal damage of seal members
(See Priming the Shallow Well or Priming the Deep Well Sections).
WATERLOGGED TANKS: CONVENTIONAL
When a tank system has an inadequate ratio of air and water, the pump
will start and stop often and erratically.
1. Disconnect the power to the pump.
2. Open the lowest faucet in the system to release all pressurized water
in the system.
3. Prime the pump (See Priming the Shallow Well or Priming the Deep
Well Sections).
4. Reconnect the power to the pump.
NOTE: As the pump refills the tank with water, the air volume control
supplies the tank with the correct air to water ratio for the system to
operate. If the air volume control is good, the pump will shut off at the
desired cut-off and will be adjusted correctly.
WATERLOGGED TANKS: PRE-CHARGED
If a pre-charged tank becomes waterlogged, the bladder is normally
leaking or broken.
1. Test the tank by depressing the air valve. The air valve will expel
water if the bladder is broken.
2. Replace the tank.
NOTE: Once an internal bladder is leaking or broken, the bladder cannot
be repaired. The tank must be replaced.
PRE-CHARGED TANK
Some air is lost through the internal bladder in any tank. To prevent tank
failure, check the tank pre-charge on a yearly basis.
1. Disconnect power to the pump
2. Open a faucet nearest the tank and allow all water to drain from the
tank.
3. Measure the tank pre-charge at the valve stem using a tire gauge.
4. If necessary, adjust the pre-charge with an air pump 28 - 30 psi on
1/2, 3/4 and 1 HP pumps.
LUBRICATION
The bearing used in the pumps are lifetime lubricated at the factory and
require no additional lubrication.
CWS REPAIR KIT
1. Disconnect power from the pump.
2. Open faucet nearest the tank and allow all of the water to drain from
the tank and pump.
3. Remove 4 cap screws holding pump housing, do not disconnect
pressure switch (Figure 12).
4. Remove pump housing from pump assembly, move it out of the
way.
5. Using a 5/16” socket or flat blade screw drive remove the 2 screws
from the diffuser on the pump assembly.
6. Remove the diffuser.
7. Remove the black plastic cap from the back of the motor, exposing
the motor shaft end.
8. Using a large flat bladed screw driver hold the motor shaft while
unscrewing the impeller.
9. Remove the seal plate. Pay attention to how the original shaft seal is
installed before disassembly.

10. Remove the shaft seal from the impeller, make sure the stainless
steel sleeve comes off the impeller, all you should see on the back of
the impeller is the brass colored threaded insert (Figure 13).
11. Remove the ceramic seat and rubber boot part of the seal from the
cast iron seal plate (Figure 13).
12. Remove the square cut gasket from the seal plate.
13. Reassemble the pump with new parts in reverse order.
14. Wipe down the seal plate to remove any debris or loose rust.
15. Push the ceramic seat of the shaft seal into the seal plate using the
cardboard ring provided to keep the ceramic face clean. You can
use a little water or dish soap to lubricate the seal pocket to make
assembly easier.
16. Slide the square cut gasket over the flange on the seal plate, make
sure not to let the gasket twist.
17. Carefully slip the seal plate over the shaft so as not to disturb seal
position in the seal plate. The seal plate must be orientated during
assembly so the two holes are on a horizontal line across the motor
shaft (Figure 14).
18. Push the bellows side of the shaft seal over the impeller hub, you
can use a little water or dish soap to lubricate the impeller hub to
make assembly easier (Figure 15). Make sure after assembly the
back carbon and white ceramic surfaces are in contact.
19. Holding the motor shaft with a flat blade screw driver thread the
impeller onto the motor shaft, hand tighten. Lubricate the nose of the
impeller with potable water safe lubricant.
20. Replace the plastic cap over the motor shaft end.
21. Reassemble the diffuser, make sure the arrow indicating the top is
pointed toward the top of the pump, torque the two screws to 30
±10 inch pounds.

22. Using the (4) cap screws reattach the pump housing and base to
the pump body. Torque the screws to 140 ±40 inch pounds.
23. Reattach the plumbing connections, reconnect the power and prime
the pump (See section on priming the pump). After reassembling the
pump check for leaks. If a leak is detected, repair before using the
pump.
