Installation

Replacing An Old Pump
WARNING Hazardous voltage. Disconnect power to pump before working on pump or motor.

1. Drain and remove the old pump. Check the old pipe for scale, lime,rust, etc., and replace it if necessary.
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.
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)

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.
2. Mount the pump as close to the well as possible.
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 or a PTFE-based pipe joint compound. Joints must be airand 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)

1. Mount the pump as close to the well as possible.
2. Assemble the foot valve, strainer, and well pipe (see Figure 2). Make sure that the foot valve works freely.
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.
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. 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 or a PTFE-based pipe joint compound.
   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)

CAUTION
Possible contamination. Do not use surface water for drinking.
The installation shown could be used for sprinkler applications.

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.
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 or a PTFE-based pipe joint compound on threaded pipe joints. Protect the foot valve assembly from fish, trash, etc, by installing a screen around it (see Figure 3).
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.
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 or a PTFE-based pipe joint compound. Joints must be airand water-tight. If the suction pipe can suck air, the pump cannot pull water from the water source.
   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)

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.
2. Run a pipe or reinforced hose from one arm of the first tee to the port on the pre-charged tank.
3. Connect the other end of the discharge tee to your plumbing system.
   Cap the tee with a threaded plug or a pressure gauge.
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. Adjust the tank pre-charge pressure to 28 PSI for a model CJ90E pump (30/50 pressure switch), or to 38 PSI for a model CJ90F pump (40/60 pressure switch).
   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 or PTFE-based joint compounds 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
NOTICE: 1 and 1-1/2 HP motors are dual voltage and are factory set to 230 V. The motor terminal board (located under the motor end cover) should look like that shown below. Use the instructions to set your motor to match your power source.

WARNING
Never connect a motor set to 115 V to a 230 V power source.

Plug Type Voltage Selector
Voltage is set to 230 V. To change to 115 V:

1. Make sure power is off.
2. Pull the voltage change plug off of the tabs.
3. Move the voltage change plug to the 115 V position.
   The plug will now cover 2 metal tabs and the arrow on the plug will line up with the 115 V arrow on the label (see Figure 6).
4. Attach the incoming power leads to the two outer screws on the pressure switch as shown in Figure 5.
5. Attach the ground wire to one of the grounding connections, shown in Figure 5.
6. If there are other wires, they should be capped.
7. Reinstall the motor end and pressure switch covers.

Dial Type Voltage Selector
Voltage is set to 230 volts. To change to 115 V:

1. Make sure power is off.
2. Turn the dial counter-clockwise until 115 shows in the dial window as shown in Figure 8.
3. Attach the incoming power leads to the two outer screws on the pressure switch as shown in Figure 7.
4. Attach the ground wire to the grounding connections as shown in Figure 7.
5. If there are other wires, they should be capped.
6. Reinstall the motor end and pressure switch covers.

WARNING
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.

Risk of explosion. Do not ground to a gas supply line.

Wiring Connections

WARNING
Risk of fire. 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 may be set for 115 V or 230 V. If necessary, reset the motor to the desired voltage, 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:

1. Connect the ground wire first as shown in Figure 5. The ground wire must be a solid copper wire at least as large as the power supply wires.
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.
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 (3 m) long, or to a ground electrode provided by the power company or the hydro authority.
4. Connect the power supply wires to the pressure switch as shown in Figure 5.
   You have just completed the wiring for your pump. Please go to Page 9 for startup preparations.

Preparing to Start the Pump

Priming

WARNING
Risk of explosion. 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.

CAUTION
Risk of burns. 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.

1. Remove the priming plug or tee 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.
2. Replace all fill plugs. Open a sink faucet.
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.
4. After the pump begins building pressure in the system, shut the faucet off. Let the pump build pressure until it shuts 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.

Winterizing the Pump
To prepare the pump for freezing temperatures:

1. Shut off power to the pump.
2. Relieve system pressure. Open a faucet and let it drain until water stops flowing.
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. Leave the plug out until you are ready to re-prime.
