GENERAL INFORMATION
NOTICE: Model Number of your pump is located on the pump shell. Record this number and keep in a safe place for future reference in the event service is needed.
The most important things you should know about your well are: (l) its total depth; (2) depth to water; (3) draw down water level.
1. The well total depth is the distance from the ground level to the well bottom.
2.
Depth to water is measured from the ground level to the water level in the well when the pump is not running.
3.
Draw down water level is the distance from ground level to the water level while water is being pumped.
In most wells, the water level drops when water is being pumped.
Usually you can obtain this information driller.

If depth of well and the distance to the water level in the well are not known, proceed as follows:
1. Tie an object that will float to the end of a ball of string and drop it into the well.
2. When float hits water and string becomes slack, mark the string and pull float from well.
Measure distance between
mark and float for the water level in the well.
3. Remove float, replace with a heavy object that will sink in water and drop it into the well until string becomes slack.
Mark string and pull object from well.
4. Measure distance between mark and object for depth of well.
If drawdown water level is not known, set pump 5 feet from the bottom of the well.

relief valve.
This relief valve is designed to protect home water systems from excessive pressure.
It is factory preset to start relieving pressure at 75 PSI (pounds per square inch).
Use only on home water systems with pumps listed in this Owners
Manual.
1. For maximum protection, locate valve within 2 ft. of the pressure tank.
2.
Install valve directly in pipe tee. Do not use any reducers or pipe extensions.
Tee must be located in main pump supply line to tank.
See diagram Page 4.
3.
Protect relief valve from freezing, dirt, and any other possible damage that would cause the valve not to function.
4.
Long lengths of pipe or hose connected to the relief valve discharge port can limit the amount of water and pressure that can be relieved, ff necessary to pipe away from relief valve, use minimum 1-1/4" plastic pipe.
5. Protect everything in the immediate area of the relief valve from water damage in the event the relief valve operates.
Gauge
A Pressure Gauge, Stock No. 2768, can be installed.
It will indicate the pressure at which pump starts and stops and any pressure in between.
The Motor
The motor is water filled type, and is ready to run as received.
Pressure Switch
Install an automatic pressure switch (Stock No. 2782) set to start pump at 40 lbs. pressure and stop pump when the system pressure reaches 60 lbs. See Figures 2 and 3, Page 4.
Tank
The tank serves two functions.
It provides a reservoir of water, which can be drawn off through the house fixture.
The tank maintains a cushion of air under pressure.
When tank pressure falls far enough, pump will start.
Two types of tanks are available: Captive Air® and Standard.
The Air Volume Control (AVC) maintains the cushion of air in Standard Tanks.
No Air Volume Control is needed with a
Captive Air® Tank.
Air Volume Control
A device mounted on a standard tank in order to keep enough air in the tank to prevent waterlogging the tank.
Operating a water system with no air cushion in the pressure tank can cause water hammer, rapid pump cycling, and damage to the system.

Overload Protector
This is a safety switch which opens when a momentary short or surge of power occurs or when the pump is stuck or locked with sand.
It prevents the motor from burning out.
It is built into the pump motor (2-Wire motors and 1/2 through 1 HP 3-Wire motors) or the Control Center (1-1/2 through 3 HP 3-Wire motors).
1/2 through 1 HP motors automatleally restart after the motor cools.
If the protector continues to open, the trouble should be located before continuing operation.
1-1/2 through 3 HP motors must be manually reset at control center.
Centering Guides
Install centering guides (Stock No. 2724) to keep the pump, pipe, and electrical cable from coming in contact with the well casing wall.
Purchase separately.
Control Center (3-Wire Pumps only)
The control center contains the electrical equipment (other than the pressure switch) needed to start and run a 3-Wire motor.
Mark mounting screw locations on the wall and hang control center as close to pressure tank as possible.
BE SURE to mount Control Center so that it hangs vertically and is level.
It may not function normally otherwise.
NOTICE: References to "2-Wire" or "3-Wire" motors refer to the load-carrying wires running to the motor.
All motors have a ground wire in addition to the load conductors, so that you will see four wires when looking at a "3-Wire" motor (3 load conductors plus a ground wire), and three wires when looking at a _2-Wire" motor (2 load conductors plus a ground wire).
"3-Wire" motors require an electrical disconnect switch plus a Control Center; "2-Wire" motors use only an electrical disconnect switch.

Hazardous voltage.
Can shock, burn, cal shock during pump operation, ground and bond the pump and motor as follows:
A. To reduce risk of electrical shock from metal parts of the assembly other than the pump, bond together all metal parts accessible at the well head (including metal discharge pipe, metal well casing, and the like). Use a metal bonding conductor at least as large as the power cable conductors running down the well to the pump's motor.
B. Clamp or weid (or both if necessary) this bonding conductor to the grounding means provided with the pump, which will be the equipment_grounding terminal, the grounding conductor on the pump housing, or an equipment-grounding

will be the conductor having green insulation; it may" also have one or more yellow stripes.
C. Ground the pump, motor, and any metallic conduit that car-
ties power cable conductors.
Ground these back to the service by connecting a copper conthtctor from the pump, motor, and conduit to the grounding screw provided within the supplyconnection box wiring compartment.
This conductor must be at least as large as the circuit conductors supplying the pump.
Save these instructions.
Surge Protection
For protection against damage caused by high voltage surges, your motor has built-in surge protectors.
NOTICE: Surge protectors will not protect against direct or near direct lightning strikes!
GROUNDING
Permanently ground all electrical components in accordance with the National Electrical Code and applicable local codes and ordinances.

CABLE SPLICING
NOTICE: Match colors of wires in cable to colors of wires coming from motor.
For #14, #12, or #10 Wire
Cable Installation
Included in the splice kit are three plastic splice insulators and four butt connectors; use two insulators on "2-Wire" motors and 3 insulators on "3-Wire" motors.
The extra connector is for the ground lead.
The insulating sleeves can be used on wire cable sizes #14, #12 and #10.
No tape is required for this type of joint. To use the insulators stagger the pigtail ends of the motor leads and the cable.
Cut each lead about 4" longer than the last one.
Method #1: Soldering
(Figure 6).
Stagger the pigtail ends of the motor leads and the cable.
Cut each lead about 4" longer than the last one.
Trim the insulation back 1/2" on each lead. Unscrew the plastic caps from the insulator.
Place parts on each end of the wire to be spliced, as shown.
Unscrew the plastic caps from the insulator.
Place parts on each end of the wire to be spliced, as shown in Figure 6.
Then proceed to splice the wires.
Strip both wire ends about
1-1/2".
Be sure the surface is scraped clean.
Overlap the two ends so there is about 1/2" space between the insulation ends.
Twist the wire about 1-1/2 turns.
With pliers, wind the remaining wire on each end closely around the other wire as shown.
Use a soldering iron and a resin core solder or pure solder with a non-acid soldering paste to solder the joint.
After splicing, center the body of the insulator over the splice.
Slide the neoprene sleeves down into the recesses in the body as far as they will go. Screw the caps on to tile insulator, tightening them securely by hand.
This makes a strong, waterproof splice.
Method #2: Crimptype Connectors (Figure 6)
Stagger the pigtail ends of the motor leads and the cable. Cut each lead about 4" longer than the last one. Trim the insulation back 1/2" on each lead. Unscrew the plastic caps from the insulator.
Place parts on each end of the wire to be spliced, as shown.
Splice the wires with a butt-type connector using a crimphag tool. After splicing, center the body of the insulator over the splice.
Slide the neoprene sleeves down into the recesses in the body as far as they will go. Screw the caps onto the insulator, tightening them securely by hand. This makes a strong waterproof splice.

NOTICE: If there is a chance that pump can overpump well, install a Pump Guard (Stock No.
2721) to prevent running pump dry.
ff depth of well and the distance to the water level in the well are not known, See page 4. The pump should not be set closer than 5 feet from the bottom of the well and should be submerged 15 to 20 feet below the draw down water level.
If the draw down water level is not known, set the pump 5 feet from the bottom of the well.
Install centering guides (purchase from Sears - Stock No.
2724).
These are used to keep pump, pipe and electrical cable centered in the well.
NOTICE: Install a torque protector (available locally) to protect pipe from twisting damage due to motor starting.
To prevent dropping anything into the well, keep the top of the casing covered.
Lay pump near the well, discharge end pointing outward.
Also lay out the well seal or pitless adapter if used, plastic pipe, safety rope, hose clamps, centering guides, tape, electrical cable and tools.
If this is a standard pressure tank installation, also lay out the bleeder orifice piping as shown in

Polyethylene Pipe is recoumaended in all "Dolt-YourselF' installations.
Steel pipe weighs 12 times as much as plastic pipe and special equipment is required.
100 PSI plastic pipe can be used to depths of 100'.
160 PSI plastic pipe can be used to depths of 220'.
The depth and the drawdown level of a new well can be obtained from the well driller.
The drawdown water level is
the lowest level to which the water in the well will drop while being pumped.

1. Install a nylon adapter in the pump discharge tapping.
Use
Teflon tape on male threads only.
2. Unroll the plastic pipe in a line away from the pump.
Be sure the ground is smooth so as not to damage the pipe or electrical cable.
3. Cut off sealed ends of plastic pipe.
Use a sharp knife or hacksaw.
PIPING INSTALLATION
4. Trim centering guides if necessary.
Centering guides will fit 6 inch or larger well casings and 1 inch drop pipe.
For
4 or 5 inch casings, the outside tabs must be trimmed with a hacksaw or knife. See marks on tabs. For drop pipe sizes
1-1/4 and 1-1/2 inch, inside hole of guide must be trimmed.
See marks on guide.
NOTE: Do not cut hole oversize.
A snug fit works best.
5. Slide centering guides on the plastic pipe.
First guide should be located about 6 inches above the pump discharge connection.
Additional guides should be located at equal intervals on the plastic pipe.
After placing first guide about 6 inches above the discharge connection, place a stainless steel hose clamp above the guide.
This will prevent guide from sliding up pipe as pump is lowered in well.
On other guides, place clamp above and below it to maintain position.
6. Slide plastic pipe on to the nylon adapter until it is up to the shoulder on the adapter.
Clamp pipe to adapter with
2 stainless steel hose clamps.
Place the screw mechanisms on clamps opposite each other.
Tape down excess length of hose clamp band.
7. Feed motor leads through the first centering guide.
Make electric cable splices according to choices on Pages 7 and
8. Stagger the splices by cutting one lead about 4 inches longer than the other one. Tape splices to the plastic pipe.
Note that staggering prevents the splices from rubbing on the well casing.
8. Unroll the balance of the electrical cable along side of plastic pipe.
Be sure not to damage the insulation or kink the wire.
Now go back and feed the cable through the centering guides located along the pipe.
9. If necessary, cut plastic pipe shorter than proper depth setting to allow for bleeder orifice piping assembly or distance down to your pitless adapter.
10. ffa standard pressure tank system is being used, make up bleeder orifice assembly as shown in installation drawings (Figure 1, Page 4).
Using teflon tape on all male threads.
Assemble this unit to the plastic pipe in same manner as outlined in Step 6.
I "x CAUTION ] Assembly may slip through well seal.
Install an elbow on the pipe above the well seat.
This safety measure will prevent dropping the pipe and pump into the well when lowering it.
11. ff a Captive Air@ pressure tank system is being used, assemble as shown in the typical pump installation with
Captive Air@ Tank (Figure 1, Page 4). Note that bleeder orifices and check valves are not used.
12. ff well seal is used, assemble safety ring in bottom part of the seal.
13.At
about every five feet, tape electrical cable to the pipe
(Figure 9). Use 1-1/2 to 2 wraps of tape.
This will allow some freedom of cable movement to allow for stretch of the plastic pipe.
Leave a surplus of electrical cable at the top for splicing purposes.
Surplus can be neatly rocked into top of well casing.
Figure 9
14.Tie
safety rope to pump discharge casting in holes provided.
Thread the rope through the centering guides.
It is not necessary to tape rope to the pipe.
Remove as ranch slack as practical and tie to ring in well seal or well cap in the case of a pidess adapter.
I& CAUTION ] Risk of cable damage and electrical shock.
Never support the weight of the pump and pipe
on the electrical cable. Use the drop pipe for this purpose.
Protect the cable from damage when lowering the unit in the well.
15. To lower the pump into the well will require one person at the well doing the actual lowering, and another at the top end of the assembly.
Stand as close as possible to well and lower the unit.
(Figure 10).
Figure I 0
Do not rub the pipe or electrical cable on the top of the casing.
The second person will bring the assembly toward the well during the lowering process.
Clean off any material picked up from the ground as you lower.
16.If this is a well seal installation, wiring can be completed after well seal is in place.
If this is a pidess adapter installation, make final splice at time of well development or when pittess adapter connection has been made.

3. With the pump and pipe in vertical position, tape cable to pipe just above and below the splice connections.
4.
Lower pump into well and tape cable to pipe every 10' with plastic tape.
For easy and safe handling in lowering pump into well, it is advisable to use a tripod with a block and tackle.
A pipe holder shotfld always be used to support the assembly on top of the well casing while making
up the next length of pipe.
See Figure 11 below.

IA CAUTION] Risk of cable damage and electrical shock.
Never support the weight of the pump and pipe on the electrical cable. Use the drop pipe for this purpose.
Protect the cable from damage when lowering the unit in the well.
5.
Add sufficient length of pipe to tbe pump discharge, using pipe joint compound on male threads, until the pump is at the proper setting.
The pump should not be set closer than 5 feet from the bottom and should be submerged 15 to 20 feet below the draw down water level. If drawdown level is not known, set the pump 5 feet from the bottom of the well.

7. Refer to Typical Pump Installation Drawings for proper method of piping depending on the type of pres-
sure tank used.
Well development and pump test
Proper well development will normally clear out all solid ma-
terials in the well water.
It will also tell you if the well is capable of supplying the full capacity of the pump.
If you are not certain of the draw down water level in your well, this can also be measured after pumping at maximum flow for a period of time.
Well development simply means pumping at very low flow rate to start with and gradually increasing the flow to its maximum.
The quality of the water must be visually checked throughout the procedure.

Low flow will not harm your pump.
With the gate valve set in this position, allow water to be pumped on the ground until it is completely clear of solids such as silt and sand.
This can be checked by catching some water in a glass container and waiting a period of time to let the solids in the water settle to the bottom of the container.
When the water completely clears, open the valve several turns to increase the flow rate and repeat the checking procedure for solids.
Continue the flow-checking procedure until the valve is completely open and water is free of solids.

Well Seal
Tighten the 4 bobs on the well seal, thus compressing the rubber sealing member and sealing the well casing, the drop pipe and the cable conduit.
A conduit fitting should be used in order to seal the cable at the top of the well seal. Install an air vent in the third opening in the sanitary well seal as shown in the diagrams, Figure 1, Page 4.
Complete Installation and Check Operation
At this point the necessary piping to complete this installation to the tank should be added.
For suggested methods of piping to the tank, refer to Figures
2 and 3, Page 4, for the pressure tank system being installed.
Where the tank and controls are installed in a basement or at another location away from the well, it is necessary that the pipe leading from the tank back to the well be buried below the frost fine to prevent freezing.
When all connections have been made, the pump is ready for operation.
Turn on switch.
The pressure switch will stop the pump at
60 PSI, and will allow it to start again when enough water has been drawn to reduce the water system pressure to 40
PSI. This can be checked by opening a faucet and drawing water until the pump starts again.
NOTICE: Be sure there is no excessive sand in the water.
Sears, Roebuck and Co. and the manufacturer cannot be responsible for damage to the pump and motor caused by excessive sand. (See Well Development.)
NOTICE: If there is a chance the pump can over-pump well, install a Pump Guard (Stock No. 2721) to protect against dry running.
Trouble
Little or no water delivered.
Air or milky water discharges
from faucets.
Pump starts too frequently,
