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.

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.

INSTALLATION FOR SURFACE WATER (Figure 3)

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 airand water-tight. If the suction pipe can suck air,

the pump cannot pull water from the well.

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.

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 Pages 7 and 8 for electrical hookup.

Figure 5: Standard Tank Connections

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. Remove the 1/8” NPT pipe plug from the pump

Air Volume Control (AVC) port (see Figure 5). Run tubing from the pump’s AVC port (see Figure

5) to the port on the AVC mounted on the tank. See instructions provided with tank and AVC for details. AVC port location will vary, depending on your pump model (see exploded views, Page 10).

Congratulations! You have just completed the

tank connection for your jet pump.

Please go to Pages 7 and 8 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.

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

MOTOR SWITCH SETTINGS

Dual-voltage motors (motors that can operate at either 115 or 230 volts), are set at the factory to 230 volts. Do not change motor voltage setting if line voltage is 230 volts, or if you have a single voltage motor.

NOTE: Never wire a 115 volt motor to a 230 volt line.

Remove Motor End Cover

If you have a dual-voltage motor, and will connect it to 115 volts, follow the procedure below.

End Cover Screws

Motor End Cover

Figure 6: Removing Motor End Cover

To change to 115 volts: Step 1. Make sure power is off. Step 2. Turn the dial counter-clockwise until 115 shows

in the dial window.

Step 3. The wires from the pressure switch should

already be attached to to power lead terminals.

Step 4. Reinstall the Motor end cover.

Pressure Switch Wiring

Motor wires connect here.

Power supply wires connect here. 230 Volt: Connect 2 hot wires (black and red)

here and cap the white (neutral) wire. It does not matter which wire goes to which screw. 115 Volt: Connect one hot wire (black or red) to one of these screws (it doesn't matter which one). Connect the white (neutral) wire to the other screw. Cap any remaining black or red wires.

Clamp the power cable to prevent strain on the terminal screws.

Connect the green (or bare copper) ground wire to the green ground screw.

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 United States 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.

You have just completed the wiring for your

pump.
