Installation

REPLACING AN OLD PUMP
Hazardous voltage. Disconnect power to pump before working on pump or motor.

• Step 1. Drain and remove the old pump. Check the old pipe for scale, lime, rust, etc., and replace it if necessary.
• Step 2. Install the pump in the system. Make sure that all pipe joints in the suction pipe are air-tight as well as water tight. If the suction pipe can suck air, the pump will not be able to pull water from the well.
• Step 3. Adjust the pump mounting height so that the plumbing connections do not put a strain on the pump body. Support the pipe so that the pump body does not take the weight of piping or fittings.
  You have just completed the well plumbing for your new shallow well jet pump. Please go to Page 6 for discharge pipe and tank connections.

WELL POINT (DRIVEN POINT) INSTALLATION (Figure 1)

• Step 1. Drive the well, using “drive couplings” and a “drive cap”. “Drive fittings” are threaded all the way through and allow the pipe ends to butt against each other so that the driving force of the maul is carried by the pipe and not by the threads. The ordinary fittings found in hardware stores are not threaded all the way through the fitting and can collapse under impact. “Drive fittings” are also smoother than standard plumbing fittings, making ground penetration easier.
• Step 2. Mount the pump as close to the well as possible.
• Step 3. Use the fewest possible fittings (especially elbows) when connecting the pipe from the well point to the pump suction port. The suction pipe should be at least as large as the suction port on the pump
  (include a check valve if your pump is not equipped with one – see Figure 1). Support the pipe so that there are no dips or sags in the pipe, so it doesn’t strain the pump body, and so that it slopes slightly upward from the well to the pump (high spots can cause air pockets which can air lock the pump). Seal the suction pipe joints with PTFE pipe thread sealant tape. Joints must be air- and water-tight. If the suction pipe can suck air, the pump cannot pull water from the well. If one well point does not supply enough water, consider connecting two or three well points to one suction pipe.
  You have just completed the suction piping for your new shallow well jet pump. Please go to Page 6 for discharge pipe and tank connections.

Figure 1: Driven Point Installation

CASED WELL INSTALLATION, 2″ OR LARGER CASING (Figure 2)

• Step 1. Mount the pump as close to the well as possible.
• Step 2. Assemble the foot valve, strainer, and well pipe (see Figure 2). Make sure that the foot valve works freely.
• Step 3. Lower the pipe into the well until the strainer is five feet above the bottom of the well. It should also be at least 10 feet below the well’s water level while the pump is running in order to prevent the pump from sucking air. Install a sanitary well seal.
• Step 4. Install a priming tee, priming plug, and suction pipe to the pump (see Figure 2). Connect the pipe from the well to the pump suction port, using the fewest possible fittings – especially elbows – as fittings increase friction in the pipe (however, include a foot valve – see Figure 2). The suction pipe should be at least as large as the suction port on the pump. Use PTFE pipe thread sealant tape on threaded pipe joints. Support the pipe so that there are no dips or sags in the pipe, so it doesn’t strain the pump body, and so that it slopes slightly upward from the well to the pump (high spots can cause air pockets which can air lock the pump). Seal the suction pipe joints with PTFE pipe thread sealant tape. Joints must be air- and water-tight.
  If the suction pipe can suck air, the pump cannot pull water from the well.
  You have just completed the suction piping for your new shallow well jet pump. Please go to Page 6 for discharge pipe and tank connections.

Figure 2: Cased Well Installation

INSTALLATION FOR SURFACE WATER (Figure 3)
Do not use surface water for drinking. The installation shown could be used for sprinkler applications.

• Step 1. The pump should be installed as close to the water as possible, with the fewest possible fittings (especially elbows) in the suction pipe. The suction pipe should be at least as large as the suction port on the pump.
• Step 2. Assemble a foot valve and suction pipe (see Figure 3). Make sure that the foot valve works freely. Use PTFE pipe thread sealant tape on threaded pipe joints. Protect the foot valve assembly from fish, trash, etc, by installing a screen around it (see Figure 3).
• Step 3. Lower the pipe into the water until the strainer is five feet above the  bottom. It should also be at least 10 feet below the water level in order to prevent the pump from sucking air.
• Step 4. Install a priming tee, priming plug, and suction pipe to the pump (see Figure 3). Support the pipe so that there are no dips or sags in the pipe, so it doesn’t strain the pump body, and so that it slopes slightly upward from the well to the pump (high spots can cause air pockets which can air lock the pump). Seal the suction pipe joints with PTFE pipe thread sealant tape. Joints must be air- and water-tight. If the suction pipe can suck air, the pump cannot pull water from the well.
  You have just completed the plumbing for your new shallow well jet pump. Please go to Page 6 for discharge pipe and tank connections.

Discharge Pipe and Pressure Tank Connections

PRE-CHARGE TANK CONNECTION (Figure 4)

• Step 1. Install two tees in the pump discharge port (see Figure 4). The pipe size must be at least as large as the discharge port.
• Step 2. Run a pipe or reinforced hose from one arm of the first tee to the port on the pre-charged tank.
• Step 3. Connect the other end of the discharge tee to your plumbing system. Cap the tee with a threaded plug or a pressure gauge.
• Step 4. Check the pre-charge of air in the tank with an ordinary tire gauge. The pre-charge should be 2 PSI less than the cut-in setting of the pump’s pressure switch. The pre-charge is measured when there is no water pressure in the tank. Your new pump has a 30/50 PSI switch, so adjust the tank pre-charge pressure to 28 PSI.
  Congratulations! You have just completed the tank connection for your jet pump.
  Please go to Page 7 for electrical hookup.

Figure 4: Pre-charged Tank Connections

STANDARD TANK CONNECTION (Figure 5)

• Step 1. Install one tee in the pump discharge port (see Figure 5).
• Step 2. Run a pipe from the pump discharge port to the inlet port of your tank. The pipe size must be at least as large as the discharge port.
• Step 3. Install a tee in the suction pipe near the pump. Install a reducer bushing down to 1/8” NPT in the tee. Run tubing from the tee to the port on the AVC mounted on the tank. Seal all joints with PTFE pipe thread sealant tape. See instructions provided with the tank and the AVC for details.
  Congratulations! You have just completed the tank connection for your jet pump.
  Please go to Page 7 for electrical hookup.

Sealing Pipe Joints
Use only PTFE pipe thread sealant tape for making all threaded connections to the pump itself. Do not use pipe joint compounds on plastic pumps: they can react with the plastic in pump components. Make sure that all pipe joints in the suction pipe are air tight as well as water tight. If the
suction pipe can suck air, the pump will not be able to pull water from the well.

Electrical

Disconnect power before working on pump, motor, pressure switch, or wiring.

MOTOR SWITCH SETTINGS
NOTE: 1/2 HP motors are wired for 115 volts only, and have no motor wiring to change.
3/4 HP or 1 HP motor terminal boards (located under the motor end cover) should look like one of 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

Figure 6: Voltage set to 230 volts, Dial Type

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.
Explosion hazard. Do not ground to a gas supply line.

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 7.

Figure 7: 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 6.
4. Attach the ground wire to the grounding connections as shown in Figure 6.
5. If there are other wires, they should be capped.
6. Reinstall the Motor end cover.

WIRING CONNECTIONS
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.

Connection Procedure:

• Step 1. Connect the ground wire first as shown in Figure 6. 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 6.

Preparing to Start the Pump

PRIMING
Never run pump against closed discharge. To do so can boil water inside pump, causing hazardous pressure in unit, risk of explosion and possibly scalding persons handling 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.

• Step 1. Remove the priming plug from the pump and fill the pump, fill all piping between the pump and the well, and make sure that all piping in the well is full. If you have also installed a priming tee in the suction piping, remove the plug from the tee and fill the suction piping.
• Step 2. Replace all fill plugs.
• Step 3. Power on! Start the pump. If you don’t have water after 2 or 3 minutes, stop the pump and remove the fill plugs. Refill the pump and piping. You may have to repeat this several times in order to get all the trapped air out of the piping. A pump lifting water 25’ may take as long as 15 minutes to prime.
• Step 4. After the pump has built up pressure in the system and shut off, check the pressure switch operation by opening a faucet or two and running enough water out to bleed off pressure until the pump starts. The pump should start when pressure drops to 30 PSI and stop when pressure reaches 50 PSI. Run the pump through one or two complete cycles to verify correct operation. This will also help clean the system of dirt and scale dislodged during installation.

Figure 8: Prime the Pump

CUATION
Pump and piping will be damaged if frozen and not drained.
Follow winterizing instructions.

WINTERIZING THE PUMP
To prepare the pump for freezing temperatures:

• Step 1. Shut off power to the pump.
• Step 2. Relieve system pressure. Open a faucet and let it drain until water stops flowing.
• Step 3. Drain the pump. Your pump may have a separate drain plug. Remove this plug and let it drain.
  Your pump may only have a plug or connection on the side of the pump. Remove this and let the pump drain. Some water will remain in the pump. A small amount of water left in the pump will not harm it if it freezes.

Troubleshooting

Fuse is blown or circuit breaker tripped Starting switch is defective

Wires at motor are loose, disconnected, or wired incorrectly

Pressure switch contacts are dirty

| Be sure switch is on.

Replace fuse or reset circuit breaker. DISCONNECT POWER; Replace starting switch.

Refer to instructions on wiring (Page 7). DISCONNECT POWER; check and tighten all wiring.

Capacitor voltage may be hazardous. To discharge capacitor, hold insulated handle screwdriver BY THE HANDLE and short capacitor terminals together. Do not touch metal screwdriver blade or capacitor terminals. If in doubt, consult a qualified electrician.

DISCONNECT POWER and file contacts with emery board or nail file.

Motor runs hot and overload kicks off| Motor is wired incorrectly Voltage is too low

Pump cycles too frequently

| Refer to instructions on wiring.

Check with power company. Install heavier wiring if wire size is too small (See Electrical / Wiring Chart).

See section below on too frequent cycling.

Motor runs but no water is delivered*

• (Note: Stop pump; then check prime before looking

for other causes. Unscrew priming plug and see if water is in priming hole).

| Pump in new installation did not pick up prime through:

Improper priming

Air leaks

Leaking foot valve or check valve Pump has lost prime through:

Air leaks

Water level below suction pipe inlet

Foot valve or strainer is plugged Ejector or impeller is plugged

Check valve or foot valve is stuck shut Pipes are frozen

Foot valve and/or strainer are buried in sand or mud

Water level is too low for shallow well setup to deliver water

| In new installation:

Re-prime according to instructions.

Check all connections on suction line, AVC, and ejector with soapy water or shaving cream.

Replace foot valve or check valve. In installation already in use:

Check all connections on suction line and shaft seal.

Lower suction line into water and re-prime. If receding water level in well exceeds 25’ (7.6M), a deep well pump is needed.

Clean foot valve or strainer. Clean ejector or impeller.

Replace check valve or foot valve.

Thaw pipes. Bury pipes below frost line. Heat pit or pump house. Raise foot valve and/or strainer above bottom of water source.

Clean foot valve and strainer.

A deep well jet package may be needed (over 25 ft. to water) to deliver water.

Pump does not deliver water to full capacity| Water level in well is lower than estimated

Steel piping (if used) is corroded or limed, causing excess friction

Piping is too small in size Packed well point

| A deep well jet will be needed if your well is more than 25’ (7.6M) depth to water.

Replace with plastic pipe where possible, otherwise with new steel pipe.

Use larger piping.

Backflush well point or sink new point.

Pump delivers water but does not shut off or pump cycles too

frequently

| Pressure switch is out of adjustment or contacts are welded together

Faucets have been left open

Venturi, nozzle or impeller is clogged

Standard pressure tank is waterlogged and has no air cushion

Pipes leak

Foot valves leak

Air charge too low in pre-charged tank

| DISCONNECT POWER; adjust or replace pressure switch.
Close faucets.Clean venturi, nozzle or impeller.

Drain tank to air volume control port. Check AVC for defects. Check all connections for air leaks.

Check connections. Replace foot valve.

DISCONNECT POWER and open faucets until all pressure is relieved.

Using tire pressure gauge, check air pressure in tank at valve stem located on the tank. 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| 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.)

| 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
