Page 5Jandy® PumpsSECTION 2.General Information2.1 IntroductionThis manual contains information for the properinstallation, operation and maintenance of Jandy®HHPlus Pumps. Procedures in this manual must befollowed exactly. To obtain additional copies of thismanual contact us at 707-776-8200, ext. 237. Foraddress information see back cover.2.2 DescriptionJandy® HHPlus Pumps are designed to meet theneeds of today's more hydraulically demanding poolequipment. The pump housing, seal plate, diffuser, hairand lint pot (pump basket), and impeller are all madefrom high quality thermoplastic materials. Thesematerials were chosen for their strength and corrosionresistance.The pump is driven by an electric motor directlyattached to the pump impeller. As the electric motorturns it causes the impeller to turn which forces waterto flow through the pump. The water flows into thehair/lint pot inlet and through the basket assembly. Thebasket assembly will pre-strain large particles. Theflow then enters the center of the pump housing, goesthrough the impeller, into the diffuser, and out thepump discharge port.SECTION 3.Preparation and Location3.1 Pump Preparation3.1.1 Upon receipt of the pump, check for cartondamage. After opening the carton, check forconcealed damage such as cracks, dents or abent base. If damage is found contact theshipper or distributor where the pump waspurchased.3.1.2 Inspect for missing parts, unions, lid, or basket.See the part lists on page 14.3.2 Pump Location3.2.1 The pump should not be elevated more than afew feet above the water level of the pool, it isbest to locate the pump within one (1) foot ofthe water level. A check valve is recommendedon the suction line to the pump.3.2.2 If the pump is located below water level, valvesshould be installed on both the suction andreturn lines to prevent back flow of pool waterduring any routine servicing that may berequired.3.2.3 The pump and other circulation equipmentshould be located a minimum of five (5) feetfrom the water. Choose a location that willminimize turns in the piping.3.2.4 The pump must be placed on a solid foundationthat will not vibrate. To further reduce thepossibility of vibration noise the pump can bebolted down, or placed on a rubber mat.3.2.5 The pump foundation must have adequatedrainage to prevent the motor from getting wet.Protect the pump from the rain and sun.3.2.6 Proper ventilation is required for the pump tooperate normally. All motors generate heat thatmust be removed by providing properventilation.3.2.7 Provide access for future service by leaving aclear area around the pump. Allow plenty ofspace above the pump to remove the lid andbasket for cleaning.3.2.8 If the equipment is under cover, provideadequate lighting.SECTION 4.Piping Design & Installation4.1 Size of Suction Pipe4.1.1 Recommended pipe size for the suction side ofthe pump is 2" for ¾ to 1½ HP. For 2 HP pumpsrecommended pipe size is 2½". For 3 HP pumpsrecommended pipe size is 3".4.2 Size of Discharge Pipe4.2.1 Recommended pipe size for the discharge sideof the pump is 2" for ¾ to 2 HP. For 3 HP pumpsrecommended pipe size is 2½".Note: All pipe sizes are able to withstand thepressures the pump will deliver, but not the flow.If the pipe is too small for the pump, or it iselevated above water, the maximum gallons perminute (GPM) may not be delivered.
