Installation

Replacing An Old Pump

Hazardous voltage. Disconnect power to pump before working on pump or motor.

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

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.
Mount the pump as close to the well as possible.
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)

Mount the pump as close to the well as possible.
Assemble the foot valve, strainer, and well pipe (see Figure 2). Make sure that the foot valve works freely.
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.
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 fordischarge pipe and tank connections.

Installation for Surface Water (Figure 3)

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.
Assemble a foot valve and suction pipe (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).
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.
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)

Install two tees in the pump discharge port (see Figure 4). The pipe size must be at least as large as the discharge port.
Run a pipe or reinforced hose from one arm of the first tee to the port on the pre-charged tank.
Connect the other end of the discharge tee to your plumbing system.
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 8 for electrical hookup.

Standard Tank Connection (Figure 5)

Install one tee in the pump discharge port (see Figure 5).
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.
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 view, Page 11).
Congratulations! You have just completed the tank connection for your jet pump.
Please go to Page 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.

Typical Pressure Booster System

Installation

Hazardous pressure. Install a relief valve as shown capable of passing entire pump flow at 75 PSI. Pump body may explode if internal pressure exceeds 75 PSI.

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.

NOTICE: The incoming flow rate must equal or exceed the minimum pump flow requirement of 6 Gallons per Minute or the pump will fail. As a rule, the pump will not increase the flow rate in the system.
A low pressure safety cutoff switch is recommended to shut off power to the pump in case of low discharge pressure caused by plugged nozzle, interruption to the incoming water supply, etc.

For pressure switch adjustment instructions, refer to the label inside the cover of the pressure switch.
The system can be located indoors or outdoors. Make sure that the site is level, solid, well drained, and protected from the weather and from freezing.

Turn off city water to house.
Install pipe as shown (Figures 6 & 7). Be sure to include unions and stop valves so pressure booster unit can be removed for service without interrupting household water supply. A spring loaded check valve ahead of the booster system and a low pressure cut offs itch after it are recommended (You may wish to replace the standard pressure switch with a pressure switch that includes a low pressure cutoff).
Use PTFE pipe thread sealant tape on all piping joints to prevent leaks. Please go to Pages 8 and 9 for electrical hookup.

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.
NOTICE: Never wire a 115 volt motor to a 230 volt line.
NOTICE: Wire TEFC motors according to wiring diagram in junction box on motor. Be sure motor is connected for correct line voltage.
NOTICE: Wire 3-Phase motors according to wiring diagram on motor. Be sure motor is connected for correct line voltage.

Remove Motor End Cover

If you have a dual-voltage motor, and will connect it to 115 volts, follow the procedure below.
You will need to remove the motor end cover to change the voltage setting.
Electrical
Your motor terminal board (located under the motor end cover) should look like the one below.

Dial Type Voltage Selector To change to 115 volts:

Make sure power is off.
Turn the dial counter-clockwise until 115 shows in the dial window.
Attach the power lead wires to the power lead terminals. Make sure the wires are secure.
Attach the ground wire to the green ground screw.
Reinstall the Motor end cover. Go to Wiring Connections below.

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.

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:

Connect the ground wire first as shown in Figure 9. The ground wire must be a solid copper wire at least as large as the power supply wires.
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.
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.
Connect the power supply wires to the pressure switch as shown in Figure 9.

Preparing to Start the Pump

Preparing to start 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

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.

Remove the priming plug from the priming tee 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.
Replace all fill plugs.
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.
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.

Nozzle Clean Out (Low Pressure)

Use an icepick or brad awl to clean out the nozzle – 3/16” maximum diameter (see Figure 11). Be sure you DO NOT enlarge the hole in the nozzle. Use PTFE pipe thread sealant tape on plug when reassembling to seal it.

Preparing to Start the Pump

Congratulations on a successful installation.
If you were unsuccessful, please refer to the Troubleshooting section (Page 14).

Troubleshooting

SYMPTOM	POSSIBLE CAUSE(S)	CORRECTIvE ACTION
Motor will not run	Disconnect switch is off

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 8). 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*

(Notice: Stop pump; then check prime before look- ing for other causes. Unscrew priming plug and see if water is in priming hole).| Pump in new installation did not pick up prime through:
1. Improper priming
2. Air leaks
3. Leaking foot valve or check valve Pump has lost prime through:
4. Air leaks
5. 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
