ELECTRICAL SAFETY
Capacitor voltage may be hazardous.
To discharge motor 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.
GENERAL SAFETY
Do not touch an operating motor. Modern motors are designed to operate at high
temperatures. To avoid burns when servicing pump, allow it to cool for 20
minutes after shut-down before handling.
Do not allow pump or any system component to freeze. To do so will void
warranty.
Pump water only with this pump.
Periodically inspect pump and system components.
Wear safety glasses at all times when working on pumps.
Keep work area clean, uncluttered and properly lighted; store properly all
unused tools and equipment.
Keep visitors at a safe distance from the work areas.
Pump body may explode if used as a booster pump unless relief valve capable of
passing full pump flow at 75 psi is installed.
WARNING
Hazardous pressure! Install pressure relief valve in discharge pipe.
Release all pressure on system before working on any component.

Discharge Pipe and Pressure Tank Connections
Figure 6: Pre-charged Tank Connections
Figure 7: Standard Tank Connections
PRE-CHARGE TANK CONNECTION (Figure 6)
If your system uses a pre-charged tank, it should be connected to the pump as
shown in Figure 6. The relief valve must be capable of passing the entire pump
capacity at 100 PSI pressure.
Check the pre-charge of air in the tank with an ordinary tire gauge. the pre-
charge is measured when there is no water pressure in the tank. Disconnect
power to the pump and drain the tank before checking the pre-charge. Your pump
has a 30/50 PSI switch, so the tank pre-charge pressure should be 28 PSI (that
is, it should be 2 PSI lower than the cut-in pressure of the pressure switch.
No AVC is required for a pre-charged tank; the 1/8” NPT AVC port on the pump
body should be plugged.
STANDARD TANK CONNECTION (Figure 7)
If your system uses a standard tank, connect it to the pump as shown in Figure
7. The relief valve used with a standard tank must be capable of pass-ing the
entire pump capacity at 75 PSI pressure.
Connect the Air Volume Control (AVC) tube to the 1/8” NPT AVC port
on the pump body. Run the tubing from the pump’s AVC port to the AVC mounted
on the tank. See the instructions provided with tank and AVC for details.
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.
Ejector Package Installation
Shallow Well or Deep Well
Ejector Package includes both a shallow well venturi (Item 2) and a deep well venturi (Item 3). See Figure 5 to determine your pumping conditions and install appropriate venturi in ejector body (Item 1). Nozzle (Item 1A) comes pre-installed in ejector body and works with both shallow well and deep well venturis.
NOTE: If installing shallow well venturi, do not damage sealing face (See drawing) or internal leakage may occur.
Electrical
Disconnect power before working on pump, motor, pressure switch, or wiring.
Your Motor Terminal Board (under the motor end cover) and Pressure Switch look
like one of those shown below. Convert to 115 Volts as shown. Do not change
motor
wiring if line voltage is 230 Volts or if you have a single voltage motor. Connect power supply as shown for your type of switch and your supply voltage.

Hazardous voltage. Can shock, burn, or kill. Connect ground wire before
connecting power sup-ply 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 National
Electrical Code (NEC) in the U.S., 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 8. 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 8.

Preparing to Start the Pump – Deep Well
Figure 9: Fill Pump
Figure 10: Prime Pump
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. Open the control valve as far as possible (see Figure 9). Then 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 installed a priming tee in the suction piping, remove the plug from the tee and fill the suction piping.
-
Step 2. Deep Well: Replace all fill plugs; close the control valve completely (Figure 10).
Shallow Well: Leave the control valve open (in a shallow well installation, the control valve always stays open).Step 3. Power on! Start the pump and watch the pressure gauge. Deep Well: The pressure should build rapidly to 50 PSI as the pump primes.
Shallow Well: The pump should pump water in two or three minutes. -
Step 4. After 2 or 3 minutes, the gauge should show pressure or you should have water. If not, stop the pump, remove the fill plugs, reopen the control valve, and refill the pump and piping. You may have to repeat this two or three times in order to get all the trapped air out of the piping. On a deep well, don’t forget to close the control valve each time before you start the pump.
-
Step 5. Deep Well only: When pressure has built up and stabilized at about 50 PSI, slowly open the control valve (see Figure 11) and let the pressure drop until the pressure gauge needle starts to flutter. When the needle flutters, close the valve just enough to stop the flutter (see Figure 11). Your pump is now operating at its most efficient point.
-
Step 6. 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.
NOTICE: Due to normal irregularities in the cup seal leather and the inner walls of the casing, packer jets do not form a perfect seal. In a dormant system, pressure will leak off over time, causing pump to cycle periodically to maintain system pressure level.

Troubleshooting
| Symptoms | Things to Do: |
|---|---|
| A. Motor will not run. | A. Check that the disconnect switch is ON and that the |
circuit breaker has not tripped or the fuse has not blown.
DISCONNECT POWER and make sure that wires connecting motor to power supply and pressure switch are tight and correctly connected (see Page 6).
If the remedies above do not solve the problem, call your well professional.
B. Motor runs hot and overload trips.| B. Turn to electrical instructions on Page 6 and verify that motor is correctly wired.
Check with the power company or hydro authority to make sure that the voltage at the pump is within + 10% of the motor’s rated nameplate voltage.
DISCONNECT POWER and make sure that the wires connecting the motor to the power supply are sized according to Table I, Page 5.
If not, rewire according to the instructions on Page 6.
If the pump is cycling too frequently, see Section E, below.
C. Motor runs but no water is delivered.| C. FIRST, check the prime; that is, make sure that the pump and all the suction piping plus the piping in the well are full of water. If they aren’t, fill them up.
In cold weather, make sure that the pipes and pump are not frozen. If they are, thaw them, watching out for split pipes and fittings as you work. Heat the pump pit or pump house and bury all piping below the frost line.
Other possible causes (call your pump professional if you suspect one of these): Air leaks in the suction line, dropping water level in the well, foot valve stuck or plugged, ejector plugged, impeller plugged, foot valve or strainer stuck in the mud in the bottom of the well, a shallow well pump installed on a well with more than 25 ft depth to water
(in this case a deep well jet pump is needed).
D. Pump does not deliver water to full capacity.| D. Possible causes are: the well water level is lower than estimated, making a different nozzle/venturi combination necessary; steel piping (if used) is corroded or limed, restricting capacity and increasing
friction; or the piping is too small for the installation. Consult your well professional for any of these conditions.
E. Pump cycles too frequently or does not shut off at all.| E. Make sure no faucets have been left open.
If system has a standard tank, make sure it isn’t waterlogged. If it is, drain it down to the level of the air volume control. Make sure the AVC isn’t defective and that there are no leaks at any connections. If system has a precharged tank, disconnect power , open all system faucets and bleed all pressure off of tank. Use a tire gauge to check
the air pressure in the tank. This should be lower than the cut-in setting of the pressure switch by 2 PSI (that is, if the pressure switch starts the pump at 30 PSI, the precharge should be 28 PSI). Check the air valve for leaks (use a soap solution) and replace the core if necessary.
If you suspect any of the following conditions, consult your well professional: leaky pipes, leaky foot valve, water level in the well lower than estimated, clogged ejector or impeller.
F. Air spurts from faucets.| F. Pump may still be priming; when priming is complete all air will have been ejected from the system.
If you suspect leaks in the suction piping, gasses in the well, or that the pump is intermittently overpumping the well (that is, drawing the water level down below the foot valve), consult your well professional.
