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. SHALLOW WELL AND OPERATION Installing the Pump INSTALLATION 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. 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. 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. 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. 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.

Use pipe 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 e. Place clamp PIPING Co., Chicago, securely.

When using a foot valve, a priming in Figure 7 is recommended. 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.

CASING until it fits over the flange 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 PIPE (OR PIPES) IN WELL INSTALLING steel clamp Illinois.

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.

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. 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. 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 tnbing and turn (loosen) it 180 ° on the 1/4" pipe fitting in the tank.

In installation already in use: a. Check all connections on suction line, air volume control, jet and shaft seal b. Lower suction line into water and re-prime. If receding water in well exceeds suction lift, a deep well pump is needed of pump in closed starting switch a. Re-ptime according to instructions b. Check all connections on suction line, air voltlme c. Replace foot valve Pump has lost prime through: a. Air leaks Check fuse 3. Replace foot valve b. Water level below 4. 2. Replace pipe where (over 20 ft. to water) possible, otherwise with new steel pipe 3. Use larger offset piping is clogged pressure switch 3. Clean jet or impeller 4. Water level in well is lower estimated than 5. Motor is wired incorrectly 5. Refer to instructions 1. Standard pressure tank is waterlogged and has no air cushion 1. Drain tank to air volume control tapping. Check air volume defects. Check for air leaks at any connection 2. Pipe leak 2. Check 3. Faucets or valves are open 3. Close faucets 4. Foot valve leaks 4. Replace foot valve 5. Replace pressure 4. Check possibility of using a deep well jet pump on wiring control for connections or valves 5. Pressure 6. Air charge too low in Captive Air* Tank Models 390.2519 and 390.2522 require 40 pounds for proper operation 6. Disconnect electrical power and open faucets until all pressure is relieved. Using automobile tire pressure gauge, check air pressure in tank at the valve stem located at top of tank. If air pressure is lower, pump air into tank from outside source until proper air pressure is reached. Check air valve for leaks, using soapy solution, and replace core if necessary. 1. 2.

First check the clamp tightening screw to see flit is tight, flit is tight and slight leakage still occurs, place a piece of wood on the clamp and firmly tap the wood with a hammer. Repeat tlxis 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.
