INSTALLATIONSTEEL PIPING INSTALLATIONSWhen steel pipe is used to install the jet, be sure all pipesare clean and the ends are reamed. Screw both 1-1/4” NPTsuction pipe and 1’’ NPT drive pipe directly into the jetbody. The special adapter nipple furnished with the jet isnot used on steel pipe installations, and should be discarded.Add sufficient piping, using pipe thread compound on thejoints until proper depth is reached.NOTICE: Pipe compound can damage plastic componentsin pump. Use only Teflon tape or Plasto-Joint Stik1 whenconnecting pipe to pump.SINGLE PIPE JETS - 2” OR 3” WELLSBefore installing jet in well, it is necessary to soften jetleathers by soaking in water for a minimum of one hour.Single pipe jets must be installed with steel suction pipingin the well. Make sure all pipes are clean and ends arereamed before lowering any piping into the well. Lookthrough pipe to make certain there are no obstructions.During the process of lowering pipe into the well, always in-stall coupling on top end of pipe and above clamp. This willprevent accidental dropping of pipe into well.Attach the jet to the first length of suction pipe 1-1/4” (NPT).Use turned couplings (furnished) on 2” wells. Standard cou-plings may be used for suction piping on 3” wells. Use pipecompound 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 thedrawdown water level. This is the level to which the waterwill drop while the well is being pumped continuously.NOTICE: Due to normal irregularities in the leather of thecup seals and the inner walls of the drop pipe, 2” packer jetsdo not form a perfect seal. In a dormant system, water willleak back into well over time and pump will normally startand cycle to maintain system pressure level.PRIMING PIPE (OR PIPES) IN WELLFill piping in well with water as each length is added, or afterpiping is complete in well. This serves to double check forleaks in piping and foot valve, and simplifies final priming ofpump.INSTALLING CASING ADAPTERSlide adapter on to well casing as far as it will go. Tightenthree bolts to seal the adapter to the casing. Place a 1” nip-ple of proper length in the drive pipe opening in the casingadapter, and tighten top nuts. This will seal the glands on toboth suction and drive piping. Add elbows and flexible pipeadapters for horizontal installations.1Lake Chemical Co., Chicago, Illinois.SHALLOW WELL INSTALLATIONAND OPERATIONInstalling the Pump on a Shallow WellA shallow well jet is available for use when the SEARS jetpump is installed on wells 20 feet or less to drawdown waterlevel.Install this jet as follows:a. Loosen the stainless steel clamp until it fits over the flangeon the jet body.b. Place O-Ring in circular groove on face of suction-driveline flange. If necessary, use petroleum jelly to hold inplace.c. Venturi that protrudes from the jet body must be insertedin top (1-1/4” NPT) tapping. For ease of assembly, lubri-cate the small O-Ring on the end of the venturi and pushthe 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 nec-essary 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 WELLA shallow well jet pump can be installed on a dug well,drilled well or with a driven point. SEARS shallow well jetpumps have a built-in check valve. In a dug or cased well, afoot valve and strainer is recommended and should be in-stalled 5 to 10 feet below the lowest level to which the waterwill drop while the pump is operating (pumping waterlevel). See Figure 4, Page 5. Your well driller can furnish thisinformation. The strainer should not be too close to the bot-tom, 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 shownin Figure 7 is recommended.7182 0893Figure 7
