Assemble a plastic pipe tapping in the jet body. Regulator The impeller of the pump rotates with the motor shaft, cansing the water to fly out from its rim by centrifugal force. The rotation of the impeller creates a vacuum which _pulls" 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 right amount of water to be diverted back to the jet for the most efficient operation.

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. 6. 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. INSTALLATION 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 Stikl when connecting pipe to pump. SINGLE SHALLOW WELL AND OPERATION Installing 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 on the jet body. b. Place O-Ring in circular line flange. If necessary, place. c. Venturi that protrudes from the jet body must be inserted in top (1-1/4" NP'I') 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. PIPE JETS - 2" OR 3" WELLS Be_foreinstalling jet in well, it is necessary to soften jet leathers by soaking in water for a minimum of one hour. the Pump INSTALLATION steel clamp until it fits over the flange groove on face of suction-drive use petroleum jelly to hold in 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. d. Align lugs on jet body with slots in pump. 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. 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. Attach the jet to the first length of suction pipe 1-1/4" (NPT). 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. Tigl3t.en gac!_l_¢ngth 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 normally start and cycle to maintain system pressure level. PRIMING PIPE (OR PIPES) e. Place clamp PIPING CASING Co., Chicago, securely. WELL 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 check to see if it works freely. When using a foot valve, a priming in Figure 7 is recommended. IN WELL 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 _ nippie of proper length in the drive pipe opening in the ciksing 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. 'Lake Chemical IN THE and tighten 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 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 over the flanges Illinois.

IAWARNING]_ run pump against closed Be sure the total lift from the pumping water level to the pump does not exceed 20 feet if 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. Piping From Well To Pump On well point installations where the horizontal piping more than 25 feet, a check valve should be installed shown in Figures 3 and 4, Page 5. is as 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 S_ .ha!!..Qw,_W.ellJets 1-1/4" 1-1/2" 2" Up to 25 Ft. 25 to 50 Ft. 50 to 200 Ft.

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.

Be sure pressure regulator located on pump body is open at all times during priming and running. Turn counterclockwise all the way. DRAINING FOR WINTER 2. Remove priming plug. Fill pump with water. Replace priming plug. If 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. 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. 3. 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. To drain an air volume control, remove AVC tubing and turn (loosen) it 180 ° on the 1/4" pipe fitting in the tank.

A GASEOUS 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 12). Since the gases rise in the well casing, the water sucked down through the pipe and into the suction pipe is free of gas. It is imperative that this type of well be vented to the outside of any enclosure. JET matter TO HANDLE 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 12. and reassemble. CLEANING 1. HOW with a socket wrench, if possible, and dean. If nozzle cannot be removed, clean as explained in steps 5, 6, and 7 under Cleaning Shallow Well Jet section above. Figure HOW TO AVOID OVER-PUMPING A SHALLOW WELL In the section on Pa'iming 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. 12 12 TROUBLESHOOTING _m6sm_ causes) SYMlqOM Motor will not rtax CORRECIIVE 1.

If it is tight and slight leakage still occurs, place a piece of wood on the clamp and firmly tap the wood with a hammer. Repeat this operation around the edge of the clamp and retighten the clamp screw. If leak continues, disassemble clamp and pump halves and check to see that O-Ring is properly seated and no foreign material is on O-Ring or O seat. Reassemble pump.
