• 2" for .75 to 1.5 HP*• 2½" for 2.0 HP*• 3" for 3.0 HP*• 4" for 5.0 HP** HP refers to full-rated pumpsNOTE All pipe sizes are able to withstand the pressuresthe pump will deliver, but not necessarily the flow. Ifthe pipe is too small for the pump, or it is elevatedabove water, the maximum gallons per minute (GPM)may not be delivered. If this happens, the pump willdevelop an air pocket (cavitation) that will make noiseand the pump life will be shortened.3.1.3.3 Installation Recommendations1. If the pump is located below water level,isolation valves must be installed on both sidesof the pump to prevent back flow of pool waterduring any routine or required servicing.2. To help prevent difficulty in priming, install thesuction pipe without high points (above inletof pump - inverted “U”s in plumbing), whichcan trap air. For installations of equipmentup to 100 feet from the water, refer to thepipe sizing chart, Table 1. For installations ofequipment more than 100 feet from the water,the recommended pipe must be increased to thenext size.Table 1.

SHP Pumps come equipped with unions onboth the suction and discharge ports. Thisfeature simplifies installation and service, andeliminates the possibility of leaks at threadedadapters.4. The SHP Pump must be connected to at least two(2) hydraulically balanced main drains (suctionoutlets) for each pool pump suction line. Eachdrain (suction outlet) assembly must be providedwith covers and must be listed or certified to thelatest version of ANSI®/ASME® A112.19.8, or itssuccessor standard, ANSI/APSP-16. The suctionoutlets of the main drains must be at least three(3) feet apart or at different planes. The suctionoutlets can be a drain and skimmer, two (2)drains, two (2) skimmers, or a skimmer with anequalizer line installed. Check the local codes forproper installation requirements.NOTE To prevent entrapment, the system must be built sothat it cannot operate with the pump drawing waterfrom only one (1) main drain. At least two (2) maindrains must be connected to the pump when it is inoperation. However, if two (2) main drains run intoa single suction line, the single suction line may beequipped with a valve which will shut off both maindrains from the pump.5. The piping must be well supported and notforced together where constant stress will beexperienced.6. Always use properly sized valves. Jandy ProSeries Diverter Valves and Ball Valves typicallyhave the best flow capabilities.7. Use the fewest fittings possible. Everyadditional fitting has the effect of moving theequipment farther away from the water.NOTE If more than 10 suction fittings are needed, the pipesize must be increased.8. If this is a new installation, pressure testaccording to local codes. See Section 3.3,Pressure Testing.3.2 Electrical Installation3.2.1 Voltage ChecksThe correct voltage, as specified on the pump data plate,is necessary for proper performance and long motor life.Incorrect voltage will decrease the pump’s ability toperform and could cause overheating, reduce the motorlife, and result in higher electric bills.It is the responsibility of the electrical installer toprovide data plate operating voltage to the pump byensuring proper circuit sizes and wire sizes for thisspecific application.The National Electrical Code® (NEC®, NFPA-70 ®)requires all pool pump circuits be protected with aGround Fault Interrupter (GFCI). Therefore, it is alsothe responsibility of the electrical installer to ensure thatthe pump circuit is in compliance with this and all otherapplicable requirements of the National Electrical Code(NEC) and any other applicable installation codes.Failure to provide data plate voltage (within 10%)during operation will cause the motor to overheatand void the warranty.CAUTION3.2.2 Bonding and Grounding1. In addition to being properly grounded asdescribed below in Sec. 3.2.3, and in accordancewith the requirements of the National ElectricalCode (NEC), or in Canada the CanadianElectrical Code (CEC), the pump motor mustbe bonded to all metal parts of the swimmingPage 8ENGLISH Jandy ® Pro Series Stealth ™ Pumps | Operation Manual
