Operating Instructions and Parts Manual

Shallow Well Model Systems

1.  Shut off the power to the pump.
2.  Open the faucet nearest the tank and 

allow all water to drain from the tank.

3.  Measure the tank precharge at the 

valve stem using a tire pressure gauge.

4.  If necessary, precharge with an air 

pump to 28 - 30 psi on 1/2, 3/4 and 1 
HP pumps.

5.  Slope the horizontal pipes upward 

toward the pump to prevent trapping 
air.  If the horizontal distance 
exceeds 25 feet, see Chart 2 for the 
recommended pipe size.

Electrical

Risk of electrical

  shock.  This pump is 

designed for indoor installation only.

The voltage of power supply must match 
the voltage of the pump. All above 
ground well pumps except SWS50BOOST 
have dual voltage motors preset at the 
factory to 115 volts. The motors can be 
converted to 230 volts by turning the 
voltage selector to the desired voltage 
(See Figure 7).  Use a needle nose pliers 
to pull the selector out approximately 
1/4”, rotate and then reinsert in correct 

position. 

Select the proper size wire and 
fuse (Chart 3).  Time delay fuses are 
recommended over standard fuses for 
motor circuit protection.  All pump 
motors have built-in automatic overload 
protection that will prevent damage to 
the motor due to overheating.

Do not connect to

  electric power supply 

until unit is permanently grounded.  
Connect ground wire to approved 
ground then connect terminal provided.

A metal underground water pipe or well 
casing at least 10 feet long makes the 
best ground electrode.  If plastic pipe or 
insulated fi ttings are used, run a wire 
directly to the metal well casing or use 
a ground electrode furnished by the 
power company.

There is only one proper ground 
terminal on the unit.  The terminal(s) is 
located under the pressure switch cover, 
is painted green and is identifi ed as 
GRD.  The ground connection must be 
made at this terminal (Figure 8).  The 
ground conductor must not be smaller 
than the circuit conductors supplying the 
motor.

 Disconnect 

power

  and release all 

pressure from the system before 
attempting to install, service, relocate or 
perform any maintenance.

Operation

PRIMING THE SHALLOW WELL PUMP

To prevent damage

  to the pump, do not 

start motor until pump has been fi lled 
with water.

1.  Remove prime plug (Figure 4 or 5).
2.  Fill pump and piping completely full 

of water.

3.  Replace the prime plug.
4.  Open a faucet to vent the system.
5.  Start the motor.  Water will pump in 

a few minutes.  If pump fails to prime 
in 5 minutes, stop motor and refill 
pump with water.  Priming time is 
proportional to the amount of air in 
inlet pipe.

6.  Let the system operate for several 

minutes to flush all pipes.

7.  Close faucet and allow pump to build 

pressure in tank.  When the pressure 
reaches the cut-out setting, the 
motor will stop.

The system is now in operation and will 
automatically cycle on demand.

Maintenance

 Disconnect 

power

  and release all 

pressure from the system before 
attempting to install, service, relocate 
or perform any maintenance.  Lock the 
power disconnect in the open position.  
Tag the power disconnect to prevent 
unexpected application of power.

Protect the pump

  from freezing during 

winter conditions.

DRAINING THE PUMP

Drain openings are provided on all 
models.  To drain the pump:

1.  Remove drain plug and prime plug to 

vent the system.

2.  Drain all piping to a point below the 

freeze line.

DRAINING THE TANK

Conventional tanks can be drained by 
opening an outlet at the lowest point 
in the system.  Remove plug or the air 
volume control to vent the tank.

Precharged tanks force virtually all 
the water from the tank when system 
pressure is released.  No draining is 
necessary.

RESTARTING PUMP

If the pump has been serviced, drained 
or has not been used for some time, 
be sure there is water in the pump 
housing (volute) and the piping to the 
well.  There must be water in the pump 
housing (volute) at all times when 
the pump is running to avoid internal 
damage of seal members (Priming the 
Shallow Well).
