PRE-INSTALLATION
APPLICATION
This unit is a single stage jet pump designed for shallow water 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.
Do not use for sewage pumps, if do this, will void the warranty.

DETERMINE THE DEPTH OF YOUR WELL
Tie a small but heavy weight to the end of a piece of string. Lower the weight into the well until it reaches the bottom.
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. This number should not
exceed the maximum rated depth for your pump. If it does, it will greatly hinder or prevent the proper operation of the
pump.
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.
Air pressure in the tank must be 2 psi lower than the "cut-in" of the pressure switch.

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 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.
(Fig. 1)
2. Replace all fill plugs, 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 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.
5. 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
reaches50 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.
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.

APLICACIÓN
Esta unidad es una bomba de chorro de una etapa para aplicación con pozos poco profundos. La bomba puede
bombear agua donde el agua está ubicada menos de 25 pies (7.62 metros) verticales de la bomba. Si el agua está más
profundo que 25 pies (7.62 metros), una bomba de chorro convertible o una bomba sumergible de pozo profundo se
debería usar. Un interruptor de presión preprogramado a 30psi “ON” (PRENDIDO) y 50psi “OFF” (APAGADO) se ha
instalado en la bomba. El interruptor de presión puede prender o apagar la bomba automáticamente en cuanto a la
presión de sistema.

UBICACIÓN DE LA BOMBA
Decida el área para la instalación de la bomba. Seleccione una ubicación de la bomba con espacio adecuado para el
futuro mantenimiento de la bomba. Puede ubicarse en el sótano o lavadero de la casa, junto al pozo, o entre la casa y el
pozo. Si se instala fuera de la casa, debe estar protegida por una casa de bombas con calor auxiliar para evitar posible
congelamiento. Proteja a la bomba de inundaciones y exceso de humedad. El pozo también debe protegerse por
razones sanitarias. Monte la bomba tan ceca del pozo como sea posible.
ALMACENAMIENTO EN TANQUES PRECARGADOS
Para un mejor funcionamiento de la bomba, se recomienda que use un tanque de presión de diafragma (se vende por
separado). Lo mejor es tener éste en su lugar antes de instalar la bomba. Un tanque de almacenamiento pre-cargado
tiene una cámara flexible o diafragma que actúa como una barrera entre el aire comprimido y agua. Esta barrera impide
que el aire sea absorbido en el agua y permite que el agua actúe por aire comprimido inicialmente a presiones
atmosféricas mayores (pre-cargada). Se proporciona más agua utilizable que con un tanque de tipo convencional.
La precarga debe ser de 2 PSI menos que el ajuste de cierre del interruptor de presión de la bomba.
PRECAUCIÓN: Para que la bomba y el tanque funcionen correctamente, el tanque de presión tiene que ser drenado de
toda el agua ANTES DE INSTALAR LA NUEVA BOMBA. Después del drenaje, si está utilizando el interruptor de presión
suministrado de 30/50 psi en los ajustes preestablecidos, añada o ajuste la presión de aire en el tanque a 28 psi de
presión ANTES del arranque.

Aplicación para pozo superficial
Los sistemas de pozos superficiales se identifican mediante una tubería que va al pozo, lago o río.
1. APLICACIÓN PARA POZO ENTUBADO, ENTUBADO DE 4pulg O
MÁS (Fig. 1)
Un orificio perforado en la tierra con maquinarias. Las profundidades
oscilan entre unos pocos pies y 25 pies. Los diámetros comunes de pozos
son de 4pulg, 5pulg, 6pulg y 8pulg para pozos de agua doméstica.
2. APLICACIÓN DE PUNTO DE POZO (PUNTO ACCIONADO) (Fig. 2)
La tubería con un filtro en punta se introduce en el suelo debajo de la capa
freática. La profundidad habitualmente es inferior a 25 pies. Los diámetros
disponibles son de 1pulg a 2.
3. APLICACIÓN PARA AGUA SUPERFICIAL (Fig. 3)
Una tubería va al lago, río, cisterna o estanques, la elevación por
succión es inferior a 25pi.
Instale un filtro alrededor de la tubería de entrada para evitar el
atrapamiento de nadadores, vida silvestre y escombros.
PRECAUCIÓN: Posible contaminación. No use aguas superficiales para
beber. La instalación que se muestra podría usarse para aplicaciones de
rociadores.
MONTAJE
La tubería flexible estáprohibida en la tubería de succión (tubería de entrada). Se pueden instalar uniones o
acoplamientos de manguera cerca de la bomba para facilitar la extracción para el mantenimiento o el almacenamiento.
Una manguera de goma instalada entre el sistema de agua y la tubería de la casa reduciráel ruido transmitido a la casa.
