The Air Volume 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. 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.

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. 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. 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. The control center contains the electrical equipment (other than the pressure switch) needed to start and run a 3-Wire motor.

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 lead. The equipment-grounding lead, when provided, 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 carties 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 surges, your motor has built-in surge protectors. NOTICE: Surge protectors will not protect near direct lightning strikes! against voltage direct or GROUNDING 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 (Figure 6) 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. Wire Ends Ready to Splice: Strip 1/2" back for crimp-type connectors Strip 1-1/2" back for soldered connection ff plastic well casing is used in your installation, ground the metal well cap or well seal, providing electrical leads to the pump motor go through the well cap or well seal. The grounding conductor need not be larger than the circuit conductors supplying the motor providing circuit conductors conform to the wiring data provided in this manual. NOTICE: Connectors 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. Permanently ground all electrical components in accordance with the National Electrical Code and applicable local codes and ordinances. Make a permanent ground using a conductor of correct size from a grounded lead in the service panel or a properly driven and grounded ground rod. DO NOT ground to a gas supply line. DO NOT connect to electric power supply until unit is permanently grounded. CABLE #2: Crimptype Wire Spliced (Cdmped) SPLICING Match colors of wires in cable to colors of wires / coming from motor. For #14, #12, or #10 Wire Wire Spliced (Soldered) 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.

If these simple instructions are followed, you will have a successful and professional installation that will last as long as there is water in the well NOTE: The bleeder orifices, check valve and air volume control required for standard tanks are not furnished. A special Air Volume Control Kit containing these parts is available from Sears Product Service, 1-800-366-7278. Not needed with Captive Air@ tank. 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'. 1. Install a nylon adapter in the pump discharge Teflon tape on male threads only. 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. Assembly of all components that go into the well should be made horizontally on the ground and then lowered into well. tapping. Use 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 hacksaw. ends of plastic pipe. Use a sharp knife or 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. Figure 9 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. 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. 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. 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. 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. 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.

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. 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. 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. 9 INSTALLATION 17.

Before piping up a Captive Air@ Tank, be certain air pressure in tank is the same as the cut-in pressure of the pressure switch. For additional information, see instructions on tank or in the tank owners manual. Complete piping to pressure tank. 6. Installation Well 1. with Pipe pipe into discharge and pump test The amount of time spent on well development will vary depending on the condition of the water. Allow yourself at least 2 hours continuous running and do not become alarmed if it takes 4, 5 or more hours to clear up the water. 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. q IA CAUTION] Risk of cable damage and electrical This well development no-pump wear, trouble procedure will assure free operation. you of long, Do not start pump with discharge open unless velopment procedure has been done and well 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. development 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. of pump. 3. With the pump and pipe in vertical position, tape cable to pipe just above and below the splice connections. 4. and Pump Proper well development will normally clear out all solid materials 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.
