PRE-INSTALLATION
APPLICATION
This unit is a single stage jet pump designed for shallow well applications, where the water level is less than 25 ft.
deep. If the water level to the pump is deeper than 25 ft., a convertible jet pump or a deep well submersible pump
should be used. A pressure switch pre-set at 30 PSI “on”, 50 PSI “off” has been installed on the pump. The pressure
switch will automatically turn the pump on and off based on the system pressure.
TOOLS REQUIRED
WARNING: All joints and connections must be AIRTIGHT. A single leak will prevent the proper operation of the pump.
Wrap thread tape clockwise on all threaded connections. For all non-threaded connections, you must use PVC Purple
Primer and PVC Cement to ensure airtight seals. Measure all pipe lengths before attaching.
NOTE: A foot valve is a check valve that is used to keep the water from running back into the well from the pump and
maintain hydraulic pressure when the pump is not running. If the foot valve does not hold the water the pump will lose
it’s prime and will not pump water. If the foot valve open pressure is too high (the spring is too stiff), or the flow area is
too small, the pump suction head and flow rate will significantly drop.
NOTE: For SKU # WPS05003K, SKU #WPS07503K, the suction pipe size should not be less than 1-1/4 in. the
suction size of this pump is 1-1/4 in. FNPT. For SKU # WPS05002TK, the suction pipe size should not be less than 1
in. the suction size of this pump is 1 in. FNPT.

DETERMINE THE DEPTH OF YOUR WELL
Tie a small but heavy weight such as a fishing weight to the end of a piece of cotton string. Lower the weight into the
well until it reaches the bottom of the well. Make a mark on the string at ground level. Pull the weight out of the well
and measure from the bottom of the weight to the ground level mark. This is the depth of your well. Subtract 5 ft. from
the depth of your well. If this number is less than 25 ft., shallow well installation should be taken. If this number is more
than 25 ft. and less than 70 ft., deep well installation should be taken. If this number is more than 70 ft., a deep well
submersible pump should be selected. Measure the ground level mark to the mark where the cotton string is wetted.
This number is your well’s water level. It should also be at least 10 ft. below the well’s water level while the pump is
running in order to prevent the pump from sucking air due to water level drawdown.
LOCATION OF THE PUMP
Decide on the area for the pump installation. Select a pump location with adequate space for future pump
maintenance. It can be located in the basement or utility room of the house, at the well, or between the house and the
well. If installed outside of the house, it should be protected by a pump house with auxiliary heat to prevent possible
freezing. Protect the pump against flooding and excess moisture. The well also should be protected for sanitary
reasons. Mount the pump as close to the well as possible.
TANKS - PRE-CHARGED STORAGE
For best performance of the pump, it is recommended that you use a diaphragm pressure tank (sold separately). It is
best to have this in place before installing the pump. A pre-charged storage tank has a flexible bladder or diaphragm
that acts as a barrier between the compressed air and water. This barrier prevents the air from being absorbed into
the water and allows the water to be acted on by compressed air at initially higher than atmospheric pressures (pre-
charged). More usable water is provided than with a conventional type tank.
The pump has a 30/50 PSI pressure switch, which means the "cut-in" is 30 PSI; therefore, the tank needs to be set to
28 PSI. To check the pressure in the tank, use a tire pressure gauge (not included). If the tank pre-charged less than
28 PSI, re-charge air to the tank to 28 PSI with a tire pump or air compressor. If the tank pre-charged over 28 PSI,
bleed out some air to 28 PSI.
NOTE: For AUTO series tank is included and the tank was pre-charged at 28 PSI.
WARNING: ELECTRICAL SAFETY Capacitor voltage may be hazardous. To discharge the motor capacitor, hold the
insulated handle screwdriver BY THE HANDLE and short capacitor terminals together. Do not touch the metal
screwdriver blade or capacitor terminals. If in doubt, consult a qualified electrician.
CAUTION: Do not touch an operating motor. Modern motors are designed to operate at high temperatures. To

Do not allow pump or any system component to freeze.
To do so will void warranty.
Pump water only with this pump.
Periodically inspect the pump and system components.
Wear safety glasses at all times when working on pumps.
Keep the work area clean, uncluttered and properly lighted; store properly all unused tools and equipment.
Keep visitors at a safe distance from the work areas.
WARNING: The pump body may explode if used as a booster pump unless a relief valve capable of passing full pump
flow at 75 PSI is installed.

For Well Point Installation
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.

PUMP ELECTRICAL CONNECTIONS
WARNING: It is recommended all electrical work be performed by a licensed electrician.
WARNING: When wiring from the power source to the pressure switch, it is recommended that you use either a 14-
gauge or 12-gauge cord.
WARNING: Before wiring the pressure switch, turn off the power source to which you are connecting to avoid
potentially life threatening electrical shock.

14 For Professional Technical Support call 1-844-242-2475
Wiring The Pressure Switch
To complete the installation, you must connect the
power source to the pressure switch. A 30/50 PSI
pressure switch has been installed on the pump. The
pressure switch allows for automatic operation; the
pump starts when pressure drops to the “cut-in” setting
(30 PSI pre-set).
To wire the pressure switch:
Remove the pressure switch cover on the pump to
expose the wiring terminals.
Connect the green ground wire of the power supply
to the switch ground terminal.
Connect the power supply wires to the two outside
terminals marked “LINE” and replace the switch
cover.
230 Volt: Connect 2 hot wires (black and red) to the two outside terminals on the pressure switch and cap the white
(neutral) wire. It does not matter which wire goes to which terminal.
115 Volt: Connect one hot wire (black or red) to one of the outside terminals on the pressure switch (it doesn't matter
which one). Connect the white (neutral) wire to the other terminal. Cap any remaining black or red wires.
CAUTION: Do NOT use a pressure switch set at a pressure greater than 50 psi. The pump will not create pressures
greater than 50 psi, if so the pump will never shut off, resulting in damage to the pump and voiding the warranty.
To change from 230V to 115V
This pump is pre-wired at 230 volts.
If the power source is 115 volts, remove the electrical housing cover.
Flip the switch to 115 volts. Replace the cover.
NOTE: All electrical work should be performed by a licensed electrician.
PUMP PRIMING&STARTUP
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.
WARNING: Risk of explosion and scalding. 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.
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.

For Professional Technical Support call 1-844-242-2475 15
2. Open the faucet closest to the pump/tank a small amount to allow air to escape the system.
3. Power on! Start the pump.
4. If you don’t have water, stop the pump and remove the fill plugs. 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.
5. 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.
Congratulations on a successful installation.
If you were unsuccessful, please refer to Troubleshooting or call our customer service technical staff.
CARE AND MAINTENANCE
WARNING: Disconnect power and release all pressure from the system before attempting to install, service, relocate
or perform any maintenance.
Winterizing
CAUTION: Drain the entire system if there is danger of
freezing. A drain plug is provided at the bottom of the pump
case for this purpose.
Drain openings are provided on all models to drain the
pump:
Unplug the pump from power supply outlet.
Remove drain plug close to the inlet hole.
Drain all piping to a point below the freeze line. This will
drain the pump.
NOTE: While this will drain the pump, it will not necessarily drain all the unprotected parts of the piping system. To
drain tank, disconnect the piping at the tank outlet.
SEAL ASSEMBLY REPLACEMENT
CAUTION: Make certain that the power supply is disconnected before attempting to service the unit! The
rotary seal assembly must be handled carefully to avoid damaging the precision lapped faces of the sealing
components.
1. Disengage pump body (Ref. No. 9) from motor mounting ring (Ref. No. 11).
2. Remove diffuser (Ref. No. 6).
