INSTALLATION

NOTICE: Use Teflon tape supplied with the pump or Plasto Joint Still for making all pipe-thread connections to the pump itself. To avoid stress- cracking, do not use pipe joint compounds on the pump.

Wrap male pipe threads being attached to pump with one or two layers of Teflon tape. Cover entire threaded portion of pipe.
Do not overtighten threaded fittings in the plastic pump. Be sure you do not try to tighten joint past thread stop in pump port!
If leaks occur, remove fittings, clean off old tape, rewrap with one to two layers of tape and remake the connection. If joint still leaks, replace the fittings (fittings may be undersized).
Be sure to support all piping connected to the System.

MAJOR COMPONENTS AND WHAT THEY DO

Tank and Air Volume Control

The tank serves two functions. It provides a reservoir of water, some of which can be drawn through the house fixture before the pump must start, and it maintains a cushion of air under pressure. When Captive Air + Tanks are used, no air volume control is necessary. This tank contains a permanent pre-charge of air. When a Standard Tank is used, an air volume control adds air to the tank when it is needed. See instructions included with Air Volume Control for details on installation and operation.

Pressure Switch

The pressure switch provides for automatic operation.

Impeller, Jet and Pressure Regulator
The impeller of the pump rotates with the motor shaft, causing the water to fly out from its rim by centrifugal force. The rotation of the impeller creates a vacuum which “puns” in more water. Part of the water is diverted back to the jet where it again passes through the nozzle and venturi – creating additional vacuum to draw in more water and delivering it at high pressure to the impeller. In a deep well installation, the jet assembly is submerged in the well because the vertical distance to the water level exceeds the suction lift of the pump. Adjustment of the pressure regulator causes the fight amount of water to be diverted back to the jet for the most efficient operation.

In a shallow well installation, the jet assembly is attached directly to the pump because the vacuum created will pull water to the pump. The pressure regulator may be used to restrict the flow of water in a shallow well system if the SEARS convertible pump produces more water than the well can produce.

DEEP WELL PUMP INSTALLATION

(Figures I & 2, Page 4)
In a deep well installation, the jet assembly is submerged in the well because the vertical distance to the water level exceeds the suction lift of the pump. A single pipe system must be used in 2″ and 3″ wells. A double pipe system must be used in 4″ or larger wells. Follow instructions packed with jet package for proper nozzle and venturi combination for your ptmaping depth.

DOUBLE PIPE JET
When a double pipe jet is selected, 2 pipes are used in the well. One is the suction pipe, and the other, the pressure pipe. Plastic pipe is ideal for double pipe installations, due to its light weight mid easy installation. Use 100 ponnd flexible plastic pipe on horizontal jet pumps.

TO INSTALL 4″ DOUBLE PIPE JET
First, inspect jet to make sure no foreign matter has entered the openings. Be certain no foreign matter enters pipe openings while installing the unit.

Plastic Pipe Installations

Attach a foot valve (not furnished) to the jet with a short nipple.
Before installing, be certain foot valve operates freely.
A special plastic pipe adapter is included with the jet which screws into the 1-1/4″ suction tapping over the venturi.
Assemble a plastic pipe adapter (not furnished) into 1″ tapping in the jet body.
Use sufficient length of plastic pipe to place the jet 10-15 feet below the lowest drawdown water level. This is the level to which the water in the well will drop while being pumped continuously.
Tighten all hose clamps securely. A sanitary well seal is required on top of the well casing. Use steel nipples and elbows or specialized galvanized steel elbows to go through the well seat. Use plastic pipe adapters where special elbows are not used.

STEEL PIPING INSTALLATIONS
When steel pipe is used to install the jet, be sure all pipes are clean and the ends are reamed. Screw both 1-1/4″ NPT suction pipe and 1″ NPT drive pipe directly into the jet body. The special adapter nipple furnished with the jet is not used on steel pipe installations, and should be discarded. Add sufficient piping, using pipe thread compound on the joints until proper depth is reached.

NOTICE: Pipe compound can damage plastic components in pump. Use only Teflon tape or Plasto-Joint Stik’ when connecting pipe to pump.

SINGLE PIPE JETS – 2″ OR 3″ WELLS
Before installing jet in well, it is necessary to soften jet leathers by soaking in water for a minimum of one hour. Single pipe jets must be installed with steel suction piping in the well. Make sure all pipes are clean and ends are reamed before lowering any piping into the well. Look through pipe to make certain there are no obstructions. During the process of lowering pipe into the well, always install coupling on top end of pipe and above clamp. This will prevent accidental dropping of pipe into well. Attach the jet to the first length of suction pipe 1-1/4″ (NF1). Use turned couplings (furnished) on 2″ wells. Standard couplings may be used for suction piping on 3″ wells. Use pipe compound on male threads only.

Tighten each length of pipe as it is lowered into the well. Lower it to proper depth which is 10-15 feet below the drawdown water level. This is the level to which the water will drop while the well is being pumped continuously.

NOTICE: Due to normal irregularities in the leather of the cup seals and the inner walls of the drop pipe, 2″ packer jets do not form a perfect seal. In a dormant system, water will leak back into well over time and pump will normaUy start and cycle to maintain system pressure level.

PRIMING PIPE (OR PIPES) IN WELL
Fill piping in well with water as each length is added, or after piping is complete in well. This serves to double check for leaks in piping and foot valve, and simplifies final priming of pump.

INSTALLING CASING ADAPTER
Slide adapter on to well casing as far as it will go. Tighten three bolts to seal the adapter to the casing. Place a 1″ nipple of proper length in the drive pipe opening in the casing adapter, and tighten top nuts. This will seal the glands on to both suction and drive piping. Add elbows and flexible pipe adapters for horizontal installations.

SHALLOW WELL INSTALLATION AND OPERATION

Installing the Pump on a shallow Well
A shallow well jet is available for use when the SEARS jet pump is installed on wells 20 feet or less to drawdown water level.

Install this jet as follows:
a. Loosen the stainless steel clamp until it fits over the flange on the jet body.
b. Place O-Ring in circular groove on face of suction-drive line flange. If necessary, use petroleum jelly to hold in place.
c. Venturi that protrudes from the jet body must be inserted in top (1-1/4″ NV_ tapping. For ease of assembly, lubricate the small O-Ring on the end of the venturi and push the shallow well jet assembly into place.
d. Align lugs on jet body with slots in pump.
e. Place clamp over the flanges and tighten securely.
For standard tank installations, an air volume control is necessary and is connected to the 1/8″ tapping in the jet body. Connect as shown in installation drawing, Figure 4, Page 5.

PIPING IN THE WELL
A shallow well jet pump can be installed on a dug well, drilled well or with a driven point. SEARS shallow well jet pumps have a built-in check valve. In a dug or cased well, a foot valve and strainer is recommended and should be installed 5 to 10 feet below the lowest level to which the water will drop while the pump is operating (pumping water level). See Figure 4, Page 5. Your well driller can furnish this information. The strainer should not be too close to the bottom, or sediment may clog it. Before installing foot valve, check to see if it works freely.

When using a foot valve, a priming tee and a plug as shown In Figure 7 is recommended.

CAUTION
NEVER run pump dry. Running pump without water may overheat unit, damaging seals and possibly burning persons handling pump.

WARNING
VER run pump against closed discharge. To do so can boil water inside pump, causing hazardous pressure in unit and possible scalding to persons handling pump. Be sure the total lift from the pumping water level to the pump does not exceed 20 feet ff the pump is over the well, or less if the pump is offset from the well. Both figures are for sea level – the maximum lift at which the pump can operate satisfactorily, decreases with the elevation at the approximate rate of 1 foot per 1,000 feet of elevation; thus, ff the lift is 17 feet and your elevation is 3,000 feet above sea level, you would then be pumping 17 plus 3 or 20 feet, which is still satisfactory for shallow well pumping.

Horizontal Piping From Well To Pump
On well point installations where the horizontal piping is more than 25 feet, a check valve should be installed as shown in Figures 3 and 4, Page 5. When the pump is offset more than 25 feet from the well, horizontal piping should be increased in size to reduced friction losses. In no case should the offset piping be smaller than the suction tapping of the pump.

Horizontal Offset Piping Sizes
Shallow Well Jets

Horizontal Offset Piping Sizes
Deep Well Jets

Discharge Pipe Sizes
When the pump is set a distance from the house, barns, or other points of water use, the discharge pipe size should be increased to reduce pressure losses.

PUMP INSTALLATION
SEARS jet pumps can be used with Captive Air s Tanks as shown in Figure 1, Page 4, and Figure 3, Page 5. For mounting pump to tank, order tank fittings Kit No. 2788. Captive Air* Tanks are pre-charged with air at the factory. Check operating instructions with tank to determine if air charge needs adjustment. Models 390.2519 and 390.2522 require 40 pounds for proper operation.

EMERGENCY POWER
In some areas and with some installations, an emergency power supply to guard against power failure is a good idea. If you install an engine-generator set for emergency backup power for your pump, supply the generator set manufacturer with the nameplate data from the pump motor. He will then be able to provide a generator of the correct size to power your pump. Also, be sure to add the load from any other accessories (such as lights) that may be on the same circuit.

ELECTRICAL

Disconnect power before working on pump, motor, pressure switch, or wiring.

Motor Switch Settings
If the motor can operate at either 115 or 230 volts, it is set at the factory to 230 volts. Do not change motor voltage setting if line voltage is 230 volts, or if you have a single voltage motor.
NOTICE: Never wire a 115 volt motor to a 230 volt line.

Remove Motor End Cover

You will need to remove the motor end cover to change the voltage setting. The illustration above also shows the pressure switch. If the power supply connection still needs to be made, the pressure switch cover will need to he removed. Your motor terminal board (located under the motor end cover) should look like the one at right.

Dial Type Voltage Selector

To change to I 15 volts:

Make sure power is off.
Turn the dial counter-clockwise until 115 shows in the dial window.
Reinstall the Motor end cover
Go to Wiring Connections, Page 10.

WARNING
Hazardous voltage. Can shock, burn, or kill. Connect ground wire before connecting power supply wires. Use the wire size (including the ground wire) specified in the wiring chart. If possible, connect the pump to a separate branch circuit with no other appliances on it.

WARNING
Explosion hazard. Do not ground to a gas supply line.

Wiring Connections
WARNING
Fire hazard. Incorrect voltage can cause a fire or seriously damage the motor and voids the warranty. The supply voltage must be within _+10% of the motor nameplate voltage.

NOTICE: Dual-voltage motors are factory wired for 230 volts. If necessary, reconnect the motor for 115 volts, as shown. Do not alter the wiring in single voltage motors. Install, ground, wire, and maintain your pump in compliance with the National Electrical Code (NEC) or the Canadian Electrical Code (CEC), as applicable, and with all local codes and ordinances that apply. Consult your local building inspector for code information.

Power supply wires connect here. 230 Volt: Connect 2 hot wires (black and red) here and cap the white (neutral) wire. it does not matter which wire goes to which screw. 115 Volt: Connect one hot wire (black or red) to one of these screws (it doesn’t matter which one). Connect the white (neutral) wire to the other screw. Cap any remaining black or red wires. prevent strain on the terminal screws.
Connect the green (or bare copper) ground wire to the green ground screw.

Connection Procedure

Connect the ground vdre first as shown in Figure 10. The ground wire must be a soEd copper wire at least as large as the power supply wires.
There must be a solid metal connection between the pressure switch and the motor for motor grounding protection. If the pressure switch is not connected to the motor, connect the green ground screw in the switch to the green ground screw under the motor end cover. Use a solid copper vdre at least as large as the power supply wires.
Connect the ground wire to a grounded lead in a service panel, to a metal undergrotmd water pipe, to a metal well casing at least ten feet (3/7I) long, or to a ground electrode provided by the power company or the hydro authority.
Connect the power supply wires to the pressure switch as shown in Figure 10.

RECOMMENDED FUSING AND WIRING DATA

Time delayed fuses are recommended instead of fuses in any motor circuit.

OPERATION

PRIMING THE SHALLOW WELL PUMP
TO PREVENT DAMAGE TO INTERNAL PARTS, DO NOT START MOTOR UNTIL PUMP HAS BEEN FILLED WITH WATER.

Be sure pressure regulator located on pump body is open at all times during priming and running. Turn counterclockwise all the way.
Remove priming plug. Fill pump with water. Replacepriming plug. ff a priming tee and plug have been provided for a long horizontal run, be sure this line is filled and the plug replaced, using pipe compound on plug threads. See Figure 7, Page 7.
Start the pump and run for approximately thirty (30) seconds. Stop pump, remove prime plug and refill with water. Replace prime plug and gauge and restart pump. Water will be pumped in a few minutes, the time depending on the depth to water and length of horizontal run. If pump does not prime, check for a possible leak on the suction side of pump. Check to be sure suction lift – distance from water level to pump – does not exceed twenty (20) feet.

PRIMING THE DEEP WELL PUMP
TO PREVENT DAMAGE TO INTERNAL PARTS, DO NOT START MOTOR UNTIL PUMP HAS BEEN FILLED WITH WATER.

Remove the priming plug. Open pressure regulator (turn counter-clockwise) located on the pump body. Fill pump and piping with water and replace plug and tighten only until it seals.
NOTICE: For location of pressure regulator, see Installation Diagrams on Pages 4 and 5.
Close the pressure regulator (turn clock-vflse).
Open several fancets in the house or near the tank to prevent pressure build up in tank.
Start pump. Pressure should build up rapidly as the jet and pump prime. Pressure vddl be in excess of 60 pounds. If this fails to happen, repeat 2 and 3 above.
Once unit has primed on pressure has stabilized, slowly open (turn cotmter-clockw’tse) the pressure regulator and water vdfll begin to be pumped into tank.
Continue to open pressure regulator until pressure falters (becomes erratic). At this point, close (turn clockwise) the pressure regulator slightly until pressure stabilizes. Close faucets and allow pump to pressurize the tank and shut off.
To insure pump is operating properly, alternately open and close faucets in system. With faucets open, pressure will drop until pressure switch starts pump; and with faucets closed, pressure will build up until pressure switch shuts off pump.
There are certain conditions of deep well operation whereby the pressure regulator can be completely open without any faltering of pressure and ff so, pump should be operated in this manner.

LUBRICATION
It is not necessary to lubricate the pump or its motor. The motor has two bali bearings lubricated for life. The mechanical shaft seal in the pump is water lubricated mad selfadjusting.

DRAINING FOR WINTER
When the pump is to be disconnected from service, or is in danger of freezing, it should be drained. The pump has a drain cock which must be opened. Remove the priming plug to vent the pump. Drain the pressure tank. Drain all piping to a point below the freeze line. To drain an air volume control, remove AVC tnbing and turn (loosen) it 180 ° on the 1/4″ pipe fitting in the tank. This vdll permit any water remaining in the air volume control to drain back into the tank.

DISASSEMBLY AND ASSEMBLY OF PUMP
The SEARS Hydroglass* pump is designed for ease in servicing and maintenance.

Disassemble pump as follows:
A. Disconnect power.
B. Drain pump by opening drain cock on bottom of pump body and remove pressure switch tubing from fitting on top of pump body. This will allow air to replace the water in the pump.
C. Remove clamp, Key No. 11, Page 16, which holds the two pump halves together.
D. Remove pump base mounting bolts. Motor assembly and back half of pump can now be pulled away from pttmp front half. Carefully remove O-Ring and place in a clean area. Inside of pump is now accessible for service.
Reassembly of pump.
A. With a clean cloth, wipe out all foreign material from the large O-Ring groove on the pump back half. Also wipe clean the large O-Ring and also the small O-Ring, Key No. 6, Page 16 on the difflaser, Key No. 10, Page 16. This will insure a good tight seal.
B. Lubricate O-Rings with petroleum jelly for ease of assembly. Place large O-Ring in groove.
C. Pump halves can now be slid together tmtil they are parallel and are as close together as possible.
D. BE SURE inside of clamp is clean. Place clamp on pump halves and snug up. Alternately tighten clamp screw and tap around outside of clamp with a plastic mallet. This will insure proper seating of O-Ring and clamp.
E. Assemble base mounting bolts. Reconnect pressure switch tubing and tighten drain cock.
F. Reprime pump and turn on power.

CLEANING IMPELLER

Disassemble pump per disassembly instruction on Page 11.
Remove diffuser and impeller from pump.
Clean impeller and reassemble,

CLEANING SHALLOW WELL JET
To remove a stone or other foreign matter from venturi or nozzle, proceed as follows:

Disconnect power, and release all pressure on system.
If pump has an air volume control, unscrew compression nut from fitting in lower portion of jet body. Tube will not pull out of fitting.
Remove suction piping from pump.
Remove stainless steel clamp and remove the jet assembly by pulling it STRAIGHT out and away from the pump body.
Turn venturi counter-clockwise and remove it. Tile nozzle is now exposed and should also be removed by using a 5/8″ Hex socket wrench with extension. Turn counterclockwise. If socket wrench is not available, insert an ice pick, or other similar pointed tool carefully into the nozzle. This will dislodge foreign material.
Flush foreign material out by running water through the nozzle in the smue direction as the dislodging tool was inserted. Jet body should be in a horizontal position for flushing.
Replace nozzle and venturi.
Replace jet assembly as explained under “Installing the pump on a shallow well,” Page 7.

CLEANING DEEP WELL JET

Disconnect power.
Disconnect piping and well seal or well casing adapter. Of pitless adapter is used, piping does not have to be dis. connected).
Withdraw jet assembly from well.
Unscrew and remove the venturi. Remove nozzle with a socket wrench, if possible, and clean. If nozzle cannot be removed, clean as explained in steps 5, 6, and 7 reader Cleaning Shallow Well Jet section above.

HOW TO AVOID OVER-PUMPING A SHALLOW WELL
In the section on Priming The Shallow Well Pump, Page 10, the instructions were to open the pressure regulator all the way after the pump starts to deliver water. If you are over-pumping your well, however, you can partially close the pressure regulator on your SEARS jet pump to increase the pressure and reduce the delivery.

HOW TO HANDLE A GASEOUS WELL
In some localities well water contains gases which must be allowed to escape before the water is used. This can be done as shown in Figure 14. A good way of delivering gas-free water is to suspend a pipe, closed at the bottom and open at the top, surrounding the suction pipe (Figure 14). Since the gases rise in tile well casing, the water sucked clown through the pipe and into the suction pipe is free of gas. It is imperative that this _’pe of well be vented to the outside of any enclosure.

AIR CONTROL IN FLOWING WELLS
Flowing wells, or wells with little or no drawdown, could create a special problem in air control in the operation of your water system. In such cases, it is recommended that you install a Captive Tank, in which an air control mechanism is not required.
