GENERAL INFORMATION NOTICE : Model Number of your pump is located on the Record the following information at the time of pump shell . Record this number and keep in a safe place for installation and retain R for future reference : future reference in the event service is needed . Pump Model No . The most important things you should know about your well Control Center Model No . are : ( l ) its total depth ; ( 2 ) depth to water ; ( 3 ) draw down water level . Horsepower 1 . The well total depth is the distance from the ground Volts level to the well bottom . Phase 2 . Depth to water is measured from the ground level to the Hertz water level in the well when the pump is not running . Full Load Amps 3 . Draw down water level is the distance from ground level to the water level while water is being pumped . In Well Casing Diameter most wells , the water level drops when water is being Wetl Depth pumped .

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 dis - charge connection . Additional guides should be located at equal intervals on the plastic pipe . After placing first guide about 6 inches above the dis - charge 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 Figure 9 clamp above and below it to maintain position . 6 .
