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.
TOOLS REQUIRED
SPECIFICATIONS
POWER SUPPLY 115V/230V, 60 HZ., 20/15 Amp Circuit
LIQUID TEMP. RANGE 32°F to 95°F (0°- 35°C)
DISCHARGE SIZE 1 in. FNPT
SUCTION SIZE 1-1/4 in. FNPT
SHALLOW WELL WATER LEVEL 25 ft.
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.
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.

AVANT L’INSTALLATION
UTILISATION
Cet appareil est une pompe à jet monocellulaire pour puits de surface, où le niveau d’eau est inférieur à 25 pi de
profondeur. Si le niveau d’eau à la pompe est plus profond que 25 pi, il faut se servir d’une pompe à jet convertible
ou d’une pompe submersible pour puits profond. Cette pompe est équipée d’un pressostat préréglé à 30 lb/po²
«marche», 50 lb/po² «arrêt». Le pressostat met en marche et arrête automatiquement la pompe en fonction de la
pression du système.
Ne pas utiliser pour les pompes à eaux usées, sinon cela annulera la garantie.

Diamètre du tuyau d’aspiration° 1-1/4 po. FNPT
Pompage de puits peu profonds 25 pi.
Déterminez la profondeur du puits.
Attachez un poids de petite taille mais lourd (p. ex., un plomb de pêche) à l’extrémité d’une ficelle de coton
(assurez-vous que la ficelle est suffisamment longue; certains puits sont très profonds). Descendez le poids dans le
puits jusqu’à ce qu’il touche le fond. Tendez la ficelle et faites une marque au niveau du sol. Tirez le poids hors du puits
et mesurez la distance entre le bas du poids et la marque de niveau du sol. Cette mesure correspond à la profondeur du
puits. De cette mesure, enlevez cinq pieds. Ce nombre ne doit pas dépasser la profondeur nominale maximale de votre
pompe. Si c'est le cas, cela gênera ou empêchera considérablement le bon fonctionnement de la pompe.
EMPLACEMENT DE LA POMPE
Déterminez l’endroit où vous placerez la pompe. Celui-ci doit offrir suffisamment d’espace pour permettre l’entretien de
la pompe. Elle peut être placée au sous-sol ou dans une pièce de rangement de votre maison, près du puits ou entre la
maison et le puits. Si elle est installée à l’extérieur de la maison, elle doit être protégée par une remise avec chauffage
auxiliaire pour éviter qu’elle ne gèle. Protégez la pompe contre les dommages causés par les inondations et l’humidité
excessive. Afin de protéger le puits de toute source de contamination, montez la pompe le plus près possible du puits.

RÉSERVOIR PRÉCHARGÉ
Pour obtenir un rendement optimal de la pompe et en prolonger la vie, il est recommandé d’utiliser un réservoir sous
pression à membrane (vendu séparément). Il est préférable que ce réservoir soit mis en place avant d’installer la
pompe. Le réservoir de 6 gallons préchargé est muni d'une paroi souple (une membrane) qui agit en quelque sorte
comme une barrière entre l'air comprimé et l'eau. Cette barrière empêche l’absorption d’air dans l’eau et permet l’action
par l’air comprimé aux pressions de début plus élevées que la pression atmosphérique. Ce réservoir permet de fournir
plus d’eau qu’un réservoir standard.
La précharge doit être de 2 lb/po2 inférieure au réglage de la pression d'enclenchement du manocontacteur de la
pompe.
MISE EN GARDE: Pour que la pompe et le réservoir fonctionnent correctement, le réservoir doit être vidangé au
complet AVANT D’INSTALLER UNE NOUVELLE POMPE. Après avoir vidangé l’eau du réservoir, si vous utilisez le
régulateur de pression préréglé à 30/50 lb/po2, réglez le niveau de l’air à 28 lb/po2 à l’intérieur AVANT de mettre la
pompe en marche.

Application pour puits peu profond
Les systèmes de puits peu profonds sont identifiés par un tuyau allant au puits, au lac ou à la rivière.
1. APPLICATION DE PUITS EN BOÎTIER, BOÎTIER DE 4 PO OU
PLUS (Fig.1)
Un trou creusé dans la terre avec des machines. Les profondeurs
varient de quelques pieds à 25 pieds. Les diamètres de puits courants
sont de 4po, 5po, 6poet 8po pour les puits d'eau domestique.
2. POINT DE PUITS D'APPLICATION (POINT CONDUIT) (Fig.2)
Un tuyau avec un écran pointu est enfoncé dans le sol sous la nappe
phréatique. La profondeur est généralement inférieure à 25 pieds. Les
diamètres disponibles sont de 1po à 2.
3. APPLICATION POUR L'EAU DE SURFACE (Fig.3)
Un tuyau entre dans un lac, une rivière, une citerne ou des étangs, la
hauteur d'aspiration est inférieure à 25 pi.
Installez un écran autour du tuyau d'entrée pour empêcher le piégeage
des nageurs, de la faune et des débris.
ATTENTION: Contamination possible. N'utilisez pas d'eau de surface
pour boire. L'installation illustrée peut être utilisée pour des applications
d'arrosage automatique.
ASSEMBLAGE
Le tuyau flexible est interdit sur le tuyau d'aspiration (tuyau d'entrée). Des raccords ou des raccords de tuyau peuvent
être installés près de la pompe pour faciliter le retrait pour l'entretien ou le stockage. Un tuyau en caoutchouc installé
entre le système d'eau et la tuyauterie de la maison réduira le bruit transmis à la maison.
