Before You Install Your Pump NOTE: For proper performance, pump MUST be matched to ejector and to well depth. Use shallow well installation for wells up to 25 ft depth to water and deep well ejector for depths up to 130 ft. Step 1.Long runs and many fittings increase friction and reduce flow. Locate pump as close to well as possible: use as few elbows and fittings as possible. Use New Pipe for Best Results. Step 2.Be sure well is clear of sand. Sand will plug the pump and void the warranty. Pump Body Clean Flow! From Well 1096 0697 Figure 1: No Dirt or Scale in Suction Pipe Step 3.Protect pump and all piping from freezing. Freezing will split pipe, damage pump and void the warranty. Check locally for frost protection requirements (usually pipe must by 12” below frost line and pump must be insulated). Step 4.Be sure all pipes and foot valve are clean and in good shape. Step 5.No air pockets in suction pipe. Step 6.No leaks in suction pipe. Use PTFE pipe thread sealant tape to seal pipe joints. Step 7.Match pump to well. IMPORTANT: Flow into well must at least equal flow out through pump! Step 8.Unions installed near pump and well will aid in servicing. Leave room to use wrenches. 1100 0697 Figure 2: Foot Valve Must Work Freely Step 9.Plug 1” drive port when installing on shallow well. Shallow Well/Centrifugal Installation No ejector is used in this case, plug the smaller of the two inlet ports, using the larger for the suction pipe. Refer to Figure 6 for installation tips. Maximum depth to water for shallow well/centrifugal operation is 25 feet. No Sags NOTE: To avoid pump overloading and motor failure, install a flow control valve at the discharge to limit flow to 20 gallons per minute.

Water pressure in the casing will then soak the cup seals (see Figure 8). They should seal within 2-3 hours after installation. Step 5.With ejector set, install well casing adapter. Re­move pipe holder. Align locating lugs and tighten adapter to form seal with well casing. Cup Leathers 5 Feet or more Figure 8 NOTE: Fill pipe with water as each length is added to be sure foot valve and connections do not leak. 2357b 0697 DISCHARGE PIPE SIZES Step 1.If increasing discharge pipe size, install reducer in pump discharge port. Do not increase pipe size by stages. Step 2.When the pump is set away from the points of water use, the discharge pipe size should be increased to reduce pressure losses caused by friction. • Up to 100 ft run: Same size as pump discharge port. • 100 ft. to 300 ft run: Increase one pipe size. • 300 ft. to 600 ft run: Increase two pipe sizes. Installation7 PRESSURE TANK INSTALLATION – DEEP WELL Standard Tank Air Volume Control (AVC) Pressure Regulator 1" Discharge STANDARD TANK CONNECTION AVC Port When a standard tank is used, an air volume control (AVC) adds air to the tank when it is needed. See Figure 10 for typical standard tank installation. To connect AVC to pump, thread a 1/4” compression fitting into tapped hole on the front of the pump. Cut tubing to length to reach AVC; assemble to fitting on pump and to AVC on tank. See installation instructions provided with tank and AVC for details. 2355b 0697 PRECHARGED TANK CONNECTION Relief Valve AVC Tubing The Pressure Tank provides a reservoir of water under pressure and maintains cushion of air pressure to prevent pipe hammering and possible damage to plumbing components. When water is drawn off through house fixtures, the pressure in the tank is lowered and the pressure switch starts the pump. Well Seal Figure 9: Pump With Standard Tank When a precharged tank is used, no AVC is necessary. See Figure 10 for typical precharged tank installation. A precharged tank contains a factory provided air charge. IMPORTANT: your pump pressure switch is set for a 30-50 PSI range and requires a tank pre-charge of 28 PSI for proper operation (see Figure 11). See tank owner’s air charge. An annual check on tank charge is recommended.

Motor Switch Settings 1 HP motor terminal boards (located under the motor end cover) should look like those below. If the motor can operate at either 115 or 230 volts, it is set at the factory to 230 volts. Do not change motor wiring if line voltage is 230 volts, or if you have a single voltage motor. Never wire a 115 volt motor to a 230 volt line. Dial Type Voltage Selector Hazardous voltage. Can shock, burn, or kill. Connect ground wire before connecting power supply wires. Use the wire size (including the ground wire) specified in the wiring chart. If possible, connect the pump to a separate branch circuit with no other appliances on it. Power Supply Connections supply line. Voltage Change Dial Explosion hazard. Do not ground to a gas WIRING CONNECTIONS Pressure Switch Ground Wire Connection Figure 12: Voltage set to 230 volts, Dial Type Voltage is factory set to 230 volts. To change to 115 volts: 1.Make sure power is off. 2.Turn the dial counter-clockwise until 115 shows in the dial window as shown in Figure 13. Figure 13: Voltage set to 115 volts, Dial Type 3.Attach the incoming power leads to the two outer screws on the pressure switch as shown in Figure 14. 4.Attach the ground wire to the grounding connections as shown in Figure 12. 5.If there are other wires, they should be capped. 6.Reinstall the Motor end cover. Fire hazard. Incorrect voltage can cause a fire or seriously damage the motor and voids the warranty. The supply voltage must be within ±10% of the motor nameplate voltage. NOTICE: Dual-voltage motors are factory wired for 230 volts. If necessary, reconnect the motor for 115 volts, as shown. Do not alter the wiring in single voltage motors. Install, ground, wire, and maintain your pump in compliance with the National Electrical Code (NEC) or the Canadian Electrical Code (CEC), as applicable, and with all local codes and ordinances that apply. Consult your local building inspector for code information. Electrical 9 Connection Procedure: Step 1.Connect the ground wire first as shown in Figure 12. The ground wire must be a solid copper wire at least as large as the power supply wires. Step 2.There must be a solid metal connection between the pressure switch and the motor for motor grounding protection. If the pressure switch is not connected to the motor, connect the green ground screw in the switch to the green ground screw under the motor end cover. Use a solid copper wire at least as large as the power supply wires. Step 3.Connect the ground wire to a grounded lead in a service panel, to a metal underground water pipe, to a metal well casing at least ten feet (3M) long, or to a ground electrode provided by the power company or the hydro authority. Step 4.Connect the power supply wires to the pressure switch as shown in Figure 12. WIRING CHART – Recommended Wire and Fuse Sizes BRANCH DISTANCE IN FEET FROM MOTOR TO METER MAX.

Operation10 PRIMING THE PUMP NEVER run pump dry. Running pump without water may cause pump to overheat, damaging seal and possibly causing burns to persons handling pump. Fill pump with water before starting. 40 60 20 NEVER run pump against closed dis­charge, to do so can boil water inside pump, causing hazardous pressure in unit and possibly scalding persons handling pump. 80 100 NOTE: Open water system faucets before priming pump for the first time. 2361a 0697 Figure 14A: Close Regulator Step 1. Remove pressure gauge. a. Close regulator valve (turn clockwise - see Figure 14A). b. Fill pump and suction pipe with water (Figure 14B). c. Replace pressure gauge, using PTFE pipe thread sealant tape on thread; tighten gauge. IMPORTANT: If a priming tee and plug have been provided for a long horizontal run, be sure to fill suction pipe through this tee and replace plug. (Don’t forget to PTFE pipe thread sealant tape the plug.) Step 2. Start Pump: Pressure should build rapidly to 50 pounds per square inch or more as ejector and pump prime. IF NO PRESSURE OR NO WATER, REPEAT Step No. 1 (above) two or three times to remove entrapped air from the suction pipes. 2360a 0697 Figure 14B: Fill Pump with Water ON Figure 14C: Start Pump 1060a 0697 Step 3.If, after priming pump several times, no water is pumped, check the following: a. Suction pipe in the water and has no leaks. NOTE: Air can leak in even where water won’t leak out. Make sure all joints are tight. b.Control valve, check valve, or foot valve installed and operating correctly. c. Pump trying to lift water more than 25 feet (shallow well) or more than rated lift for deep well ejector used (including compensation for horizontal offset). d.Be sure pump is not airlocked. In offset installations, pump suction port should be highest point in suction pipe; there should be no sags in suction pipe (run it straight and at a slight angle upward from well head to pump). NOTE: For deep well installation, go to Step 4 (Page 11). Shallow well installations go to Step 6 (Page 11). 40 20 60 80 100 1030a 0697 Figure 14D: Adjust Regulator Operation11 40 Step 4.Once unit has primed and pressure stabilized, slowly open regulator valve (turn counterclockwise - Figure 15A) until pressure falters (pressure gauge needle flutters; pump may become noisy see Figure 15B). At this point, close regulator valve slightly (turn clockwise) until pressure stabilizes. This setting provides maximum flow (Figure 15C). 60 20 80 100 2871 0697 Figure 15A: Open Regulator Valve 40 Step 6. Check system by alternately opening and closing faucets in the system. With faucets open, pressure will drop until pump starts; with faucets closed, pressure will build up until pump shuts off. 60 20 Step 5.Pump may draw well down far enough at this point to lose its prime. If so, close regulator valve until pressure is stable throughout pumping cycle. Close faucets and allow pump to pressurize tank and shut off. 80 100 Step 7.There are conditions of deep well operation when the regulator valve may be completely open without any faltering of pressure. In this case, operate pump with regulator valve completely open. HOW TO HANDLE A GASEOUS WELL 2872 0697 Figure 15B: Watch for Pressure Gauge to Flutter 40 60 20 80 100 In some areas well water contains gases which must be allowed to escape before the water is used. To deliver gas-free water suspend a pipe, closed at the bottom and open at the top, so that it surrounds the suction pipe inlet. (See Figure 16). Since the gases rise in the well casing, the water sucked down through the pipe and into the suction pump is free of gas. This type of well must be vented to the outside of any enclosure. AIR CONTROL IN FLOWING WELLS 2873 0697 Figure 15C: Close Regulator Valve until Pressure Stabilizes Gases rise to surface Ejector Pipe strap or wire to hold pipe sleeve Tail pipe Foot valve Pipe sleeve Pipe cap 2876 0697 Figure 16: Gas/Air Control in Well Flowing wells or wells with little or no drawdown, could create a special problem in air control in the operation of your standard tank system. In such cases, a pre-charged tank (which needs no air control) is recommended. Maintenance 12 Pump DISAssembly/ASSEMBLY Step 1. Pull disconnect switch. Disconnect power lines from pressure switch. Step 2. Remove the two cap screws holding the pump to the flange adapter. Don’t disturb the piping in the well. Step 3. Remove the flange adapter gasket and scrape the surfaces clean. Step 4. Leaving the tubing in place, unscrew and remove the straight barbed fitting at the pressure switch. Figure 17 Step 5. Draw a line down the side of the pump with a marker to help alignment during reassembly. Mark the pump from the motor to the base volute (see Figure 17). 1801 0595 Step 6. Turn the pump upside down on the bench and block it. Remove the four cap screws from the base. With a mallet, tap upward on the base to loosen it. Lift the base off of the intermediate volute (see Figure 18). Step 7. To reduce the chance of dropping the pump onto your foot, lay it down on the bench; block it so it won’t roll. Step 8. Hold the motor shaft with pliers or vice grips through the opening in the pump adapter. Unscrew the impeller nut off the end of the shaft (see Figure 19). Figure 18 1802 0595 Step 9. The impellers are keyed to the shaft and do not unscrew. Insert two screw drivers on opposite sides under the exposed impeller and pry the impeller off (Figure 20) to remove it. Step 10.Carefully tap a small screwdriver or thin bladed chisel in between the intermediate volute and the pump adapter in two or three places around the pump to separate the castings (Figure 21). Do not mar the seal­ing surfaces; do not break pieces out of the adapter or volute – the castings are easily damaged. Step 11.Remove the intermediate volute and slide the impeller spacer off of the shaft. Figure 19 Step 12.Remove the impeller. Don’t disturb the shaft keys if you are only replacing the seal. Step 13.Rotate the seal spring retainer cup so that the slot lines up with the shaft keys; remove the cup and spring. Step 14.Remove the two cap screws holding the adapter bracket to the motor. Step 15.With two screwdrivers on opposite sides of the pump, carefully pry the pump adapter away from the motor. This will pull the seal off of the motor shaft. Use caution to make sure that the ceramic seal does not dig into the shaft and scratch the shaft’s sealing surface. Figure 20 Installation of New Seal Step 1.Clean all gasket surfaces thoroughly before reassembly. Clean the seal bore cavity in the pump adapter. Step 2.Wet the rubber seat ring with soapy water and push the stationary part of the seal into the seal bore cavity. Use a piece of 1” pipe pressing on a cardboard washer (to prevent damaging seal surface) as a press. Make sure that the seal half is fully seated in the seal bore cavity. Remove the cardboard once the seal is in place. Figure 21 Maintenance 13 Step 3. Make sure that the shaft keys are in place on the shaft. If they are not, squeeze them in place now with slip joint pliers. Do not tap them or hit them with a hammer; you could bend the shaft (see Figure 22). When the keys are correctly installed, the adapter will pass over the keys without interference. Step 4. Carefully slide the adapter over the shaft (see Figure 23). Do not damage the shaft sealing surface; it is highly polished and any slight scratches or nicks will ruin it. Use pliers – with care – no hammers. Step 5. Using the alignment marks made before disassembly, line up the adapter with the motor and bolt the adapter in place. Tighten the cap screws evenly. Step 6. Push the shaft seal and seal spring onto the shaft, after making sure that the seal faces and shaft are clean. Take care that the shaft shoulder does not damage the carbon seal face. Follow the seal spring with the spring holder; compress the spring and give the spring holder a quarter turn to lock it under the first shaft key (see Figure 24). Figure 22 Step 7. Slide the first impeller onto the shaft; follow it with the impeller spacer. Twist the impeller on the shaft to make sure that the shaft key is still in place and the impeller is locked to the shaft (the shaft should turn with the impeller). Align Marks Step 8. Install a new volute gasket, lining up the bolt holes with the bolt holes in the adapter. Make sure the gasket is right side up so that the water passage holes line up with the water passages in the volutes. Step 9. Install the intermediate volute, aligning it with the mark made before disassembly. Use the long cap screws to check this alignment. It cannot be stressed too strongly that all bolt holes and water passages of all gaskets and volutes MUST line up with each other, or the pump will not be assembled correctly. Figure 23 Step 10.Make sure the second shaft key is in place and install the second impeller. Twist the impeller to make sure that the shaft key is still in place. Hold the motor shaft with slip-joint pliers or vicegrips and install and tighten the impeller locknut. Tightening the lock nut automatically spaces the impeller correctly. Do not overtighten. Step 11.Install the base volute gasket. Make sure the gasket is right side up so that the water passage holes line up with the water passages in the volutes. Install the base volute, using the alignment marks made before disassembly. Make sure that the pump discharge will correctly meet the the piping when the pump is reinstalled. Figure 24 Step 12.Insert the four base capscrews and tighten evenly (see Figure 25). These should be easy to install if every­thing is correctly aligned. If not, don’t force them; go back over your work and find and correct the misalignment. Bolts should be easy to insert. Step 13.Reinstall the pressure switch barb fitting and pressure tube. Step 14.Reinstall the pump on the adapter flange (use a new gasket) and reconnect the wiring and grounding. Pump is now ready for operation. Make sure all marks line up.

If less than pressure switch cut-in setting (30-50 PSI), pump air into tank from outside source until air pressure is 2 PSI less than cut-in setting of switch. Check air valve for leaks (use soapy solution) and replace core if necessary. Air spurts from faucets When pump has picked up prime, it should pump solid water with no air. Suction pipe is sucking air. Check joints for leaks with soapy water. Consult factory about installing a sleeve in the well Lower foot valve if possible, otherwise restrict pump discharge Pump is picking up prime Leak in suction side of pump Well is gaseous Intermittent over-pumping of well. (Water drawn down below foot valve.) DISCONNECT POWER; adjust or replace pressure switch. Close faucets. Clean venturi, nozzle or impeller.
