SYSTEM COMPONENTS
Please be sure that you have all major system components
necessary to properly install the submersible pump system . Other
components may also be necessary depending on the application
requirements .
1 .
Submersible pump end
2 .
Submersible motor
3 .
Variable speed controller
4 .
Pressure tank
5 .
Pressure switch or transducer (packaged with controller)
6 .
Pressure relief valve (purchased separately)
7 .
Pressure gauge (purchased separately)
General Information
The system is capable of flows up to 40 GPM . Discharge piping
is recommended to be 1 .25" for installations in which flows will
exceed 12 GPM . The use of smaller pipe will increase friction
losses and can severely limit the maximum capacity of the
system .
This pump may be capable of pressures exceeding 325 PSI
under maximum conditions, select pipe accordingly . Consult
your pipe supplier to determine the best pipe material for the
installation
Pump Inspection
Prior to installation check the pump, motor, controller and tank for
shipment damage .
Pressure Tank
The Air-E-Tainer® tank supplied with your system has a factory
set pre-charge of 35 PSI . Installer must recheck to make sure
tank is still 35 PSI . This is 70% of the factory preset operating
pressure of 50 PSI . Any change in operating system pressure will
require that the pre charge in the tank be modified to 70% of that
pressure . See Tank Table for minimum pressure tank size .

Many pumps can develop excessive
pressure, resulting in equipment and property damage as
well as possible injury. Always install a pressure relief valve
capable of passing full pump flow at 100 PSI. Install the
pressure relief valve between the pump and pressure tank.

Pressure Relief Valve
The pressure relief valve and the discharge outlet need a flow
rating which exceeds the flow capacity of the installation at the
relief pressure . When located in an area where a water leak or
relief valve blow-off may damage property connect an adequate
drain line to the pressure relief valve . Run the line to a suitable
drain or to an area where the water will not damage property .
Not providing an adequate relief valve
can cause extreme overpressure which could result in
personal and/or property damage. It is recommended that
you manually activate the valve monthly to keep it in good
working order.
Discharge Pipe
When discharge piping requires an adapter it is recommended
that a stainless steel adapter be used . Galvanized fittings or pipe
should not be connected directly to the stainless steel discharge
head of the pump as galvanic corrosion may occur . Barb type
connectors should always be double clamped . Torque arrestors
are not required on this installation due to the soft starting
characteristics of the motor and controller
Check Valve
A check valve is factory installed in the discharge head of the
submersible pump . This maintains water within the pipe when the
pump is not operating . For well depths exceeding 100 feet, an
additional check valve should be installed every 100 feet .
Safety Rope
A safety rope eyelet is provided at the discharge of the pump . It
is recommended to attach a nylon safety rope . This will assist in
the removal of the pump and also prevent loss of the unit in the
bottom of the well due to a loose fitting or pipe deterioration .
