Your pump has been carefully packaged at the factory to prevent
damage during shipping. However, occasional damage may
occur due to rough handling. Carefully inspect your pump for
damages that could cause failures. Report any damage to your
carrier or your point of purchase.

Use the included ow control valve to connect your pump to your home plumbing distribution

pipe system. Install this valve to the pump discharge and close the valve completely by
turning the top screw clockwise. Then, turn the screw counter-clockwise for one turn only
and proceed to the following priming process of the pump.

Follow all these inside step by step instructions to install your pump. Use teon tape on all
threads. (1) Install the pump discharge ttings as illustrated. (2) Fill the suction line with
water and connect it to the suction inlet. (3) Remove the priming plug and ll the pump body

with water. (4) Screw the plug to the priming inlet. (5) Turn the power on. The pump should
deliver water to the plumbing line within 30
seconds. If not, unplug the pump and repeat the
process at step 3.

After priming the pump, you can adjust the ow

control valve to obtain the best performance of
the pump. Remember that when you open this
valve, you reduce the suction capacity. This

valve is used to balance the discharge ow with

the suction requirement. The deeper your suction
distance, the more closed the valve should be for
optimum performance.

Your ejector is factory pre-assembled with the venturi

510066.2, for an optimum performance when the
pumping level is between 25’ to 60’ (7.5 meters to 18
meters) depth, in reference to the pump position.
So, this is a deep well application mode. The ejector is
positioned into the well and is connected to the pump
using 2 pipes (see page 5).

• High performance noryl impeller..

• Industrial motor totally enclosed, fan cooled.

• Full time connected run capacitor, to eliminate star-

ting wear vs regular motor.

• Thermal and overload protection.

• Built for a continuous use.

it by the venturi 510066.1. Then screw the

ejector to the pump body. This becomes a shallow well mode application where only one pipe is required
to pump water (see page 4).

INSTALLATION STEPS

We recommend that you install your pump in a clean and dry location where there is adequate room

STEP 1

for servicing at a later date. Protection from freezing temperatures and good ventilation should be
considered as well, to provide the pump an environment for long life. Locating the pump as close as
possible to the water source will reduce friction losses encountered in the suction pipe.

Friction losses in the suction pipe must be taken into consideration when the horizontal offset is greater
than 50 feet. The suction pipes should be increased from 1” to 1 1/4”. This will reduce friction losses and
allow the pump to give maximum performance.

A new well should be checked to determine that it is free from sand. Sand will damage the seal and the
impeller. Have your well driller clean the well before your installation.

Never run the pump dry. Damage to the seal may occur. Fill pump body and suction pipe with water
before turning on the power.

THE RUN OF HORIZONTAL PIPE FROM THE TOP OF YOUR WELL INTO THE HOUSE, WHERE
YOUR PUMP WILL BE LOCATED, MUST BE INSTALLED IN A TRENCH, BELOW THE FROST LEVEL
OF YOUR AREA.

Locate your injector body in your package. Using teon tape, screw the 1 1/4” venturi adaptor

over the injector venturi (black tube), into the 1 1/4” opening of injector body. Install the 1”
male thread adaptor in the 1” opening in injector body. Securely tighten both adaptors with
pipe wrench.

With teon tape on threads, install a 1” nipple into the 1” foot valve, then screw this assembly

into the 1” bottom opening of the injector.

Cut the desired length of 1” and 1 1/4” poly pipes to run from the top of the well to the pumping

level. Smooth the pipe cuttings with your round le. (Check that no cut-out parts are left

inside of pipe. This may block pump injector or impeller). Slide 2 stainless steel clamps over
one end of each pipe and use torch to soften pipe. Fix the 1” and 1 1/4” pipes respectively
on the 1” adaptor and 1 1/4” venturi adaptor. Tighten clamps with screwdriver when cool.

For security against leaks, we suggest to install 2 stainless steel clamps on each
adaptor.

Insert both well seal elbows thru their opening of the seal. Slide 2 stainless steel clamps over
the free ends of the previously cut pipes and soften pipes with your torch. Attach pipes to the
well seal elbows (ends protruding at bottom of well seal). Tighten clamps with screwdriver
when cool.

To facilitate servicing at a later date, you may use a pitless adaptor and a sealed well cap
instead of an elbow and a well seal as describe in steps 3 and 4.

STEP 8

Install the well seal and the injector piping assembly into your well casing. Tight down the well
seal bolts using your adjustable wrench.

Install your pump in the house, on a sound foundation, as close as possible to the basement
wall. Locate the openings in the front of the pump body. Thread respectively 1” and 1 1/4”

adaptors into corresponding openings using teon tape. Do not over tighten.

Cut the desired length of pipes from pump location to the well seal and connect
both ends using the previous way, with stainless steel clamps and torch.

Do not ll in your trench to the house until you have checked for any leaks in your

connections or trouble in your water system.

for sand

or well

points

Install your pump in the house, on a sound foundation, as close as possible to the basement
wall. Locate the suction inlet in the front of the injector. Thread an adaptor into inlet using

teon tape. Do not over tighten.

Cut the desired length of pipe from pump location to the well seal and connect both ends
using the previous way, with stainless steel clamps and torch. Do not ll in your trench to

the house until you have checked for any leaks in your connections or trouble in your
water system.

Sand or well points are limited to areas where water bearing sand or gravel lies below the
surface, and where there are no boulders or rocks to interfere with the driving into the ground
of the point.
The amount of water any “one” well point will supply is usually rather limited. Sometimes, it is
necessary to use more than one point to increase the supply of water, entering to the pump’s
suction.

THE IMPORTANT INSTALLATION STEP IN USING WELL POINTS IS THAT A CHECK
VALVE MUST BE USED IN THE SUCTION PIPE LEADING TO THE SUCTION INLET,
AS CLOSE TO THE PUMP AS POSSIBLE, TO KEEP SUCTION LINE AND PUMP WELL
PRIMED.

STEP 8

for captive

air tanks

TANKS INSTALLATION

SEE DIAGRAM ON PAGE 10

Packaged systems have the pump mounted directly to the tank. The pump to tank plumbing

ttings are pre-assembled in factory. You only have to connect the discharge line of your

system to your home’s plumbing distribution line. When using a separate tank from your
pump, we recommend to install a captive air tank as shown in our typical installation diagram,
that is air injected into the tank at the factory. This air, which is in addition to atmospheric
pressure, increase the ability of the tank to deliver more water between on/off cycles, thus

increasing the efciency of your water system. Connect the pump discharge to the tank T,

using adaptors and braided hose, then, connect the other side of tank T to your home’s
plumbing distribution line.

Make sure that the precharged air pressure (before connecting the tank) is 2 PSI less
than the starting pressure setted on the pressure switch of your pump. If you adjust the

air pressure after the installation, follow these steps:

- Check the starting pressure of the pump on the pressure gauge;

- Disconnect the power to the pump;

- Open nearest fawcet to the tank and relieve all pressure in tank, then close
the fawcet;

- Adjust the air pressure of the tank (by pumping or removing air at the snifter valve)
2 PSI below pressure switch “ON” setting;

- Turn power back on to pump.

Your tank is now well precharged. Run the pump through a few cycles to verify that it works
properly.

STEP 8

for epoxy or

glass lined

tanks

Not recomende

for galvanized

tanks

Other types of tanks may be used, as galvanized standard tanks, epoxy or glass lined tanks.

These products do not achieve the benets of the captive air tanks.

Epoxy or glass lined tanks with oat have to be precharged by the installer. Assuming tank is

plumbed to pump and all connections are checked for leaks, follow these steps:

- Run pump thru one complete cycle, until pump shuts off;

- Disconnect the power to the pump;

- Open nearest fawcet to the tank and relieve all pressure in tank, then close
the fawcet;

- Close service line gate valve;

- With a car tire pump, inject air into the snifter valve located in tank. Watch pump
pressure gauge and stop pumping air when pressure reachs 2 PSI below pressure
switch “ON” setting;

- Return power back on to pump;

- Run pump through one complete cycle;

- Open service line gate valve.

Your tank is now well precharged. Run the pump through a few cycles to verify that it works
properly.

Galvanized standard tanks require an air volume control to be used with jet pump. We do not
recommend the installation of this type of tank with your jet pump. This type of galvanized
tank is recommended with piston pumps.

GREEN

GROUND

To motor lead

We recommend that a licensed electrician be employed to do the proper wiring to the pressure switch,
and to permanently ground the motor in accordance to the electrical codes in your area.

Do not use an extension cord to connect your pump to the power source. From your distribution panel to the
pressure switch, we recommend a wire gauge not smaller than 14 gauge.

This is a dual voltage 115/230 pump. The voltage selection switch is located inside the terminal box.
The motor is factory wired on 115V. For 230V selection, please open the terminal cover and set the switch to
the proper voltage. (See above drawing on right ).

Pressure switch setting (start/stop 20/40 or 30/50) has been made at the factory. Adjustments may be done
to give other operating pressures.

Adjustment or modication of start/stop setting of pressure switch have to be done carefully.

Turn adjustment nut half turn at a time.

Turn nut 1 clockwise to raise start and stop pressure setting. Never turn nut 2. This will change the 20 PSI

range between start and stop pressure and may damage your tank’s bladder or modify the efciency

of your water system. Check system operation after each adjustment.
