Wayne Jet Pump JSU50 - Manual (Page 3)

(A) MANANTIAL: Un manantial que emerge de la tierra. Ocurre cuando el agua en materiales permeables está atrapada entre materiales impermeables tales como roca o arcilla.
(B) LAGO, ARROYO o EST
ANQUE:
Agua superficial, que a menos que sea tratada, por lo general no es apta para consumo humano. Puede ser utilizada para fines tales como lavado o irrigación.
(C) POZO EXCA
V ADO:
Se excava un hoyo de varios pies de diámetro hasta una profundidad basante superficial. Luego se reviste con ladrillo, piedra o concreto para evitar que se derrumbe.
(D) POZO ACCIONADO: Se acciona una tubería con una pantalla con punta en la tierra, por debajo de la capa freática. La profundidad por lo general es menor a 15,25 m (50 pies). Los diámetros comunes fluctúan entre 2,5 cm (1") y 5,1 cm (2")
(E) POZO PERFORADO: Un hoyo perforado en la tierra con maquinaria y revestido con tuberías. Las profundidades fluctúan entre algunos pies hasta más de 305 m (1000 pies). Los diámetros comunes son 5,1 cm (2"), 7,6 cm (3"), 10,2 cm (4") y 15,2 cm (6") para pozos de agua de uso doméstico.
(F) CISTERNA: Un tanque subterráneo construido para recolectar agua de lluvias de los techos. El agua no es apta para consumo humano.

As an alternative, an in-line check valve
can be used with a driven well (Figure
9).
Do not use both a
check valve and
foot valve in your system. This could
significantly reduce the performance of
the pump.
DRILLED WELL
1. Install a foot valve on the first sec-
tion of pipe (Figure 10).
2. Lower the pipe into the well.
3. Add pipe until the foot valve is 10
feet below the lowest anticipated
water level.
Leaking joints or couplings will allow
air to leak into the pipe and cause poor
pump operation. Make sure to use pipe
joint compound or Teflon
® tape on all
pipe connections.
Locate foot valve
at least 2 feet from
the bottom of the well so sand or sedi-
ment is not drawn into the system.

8. Slope horizontal lines up toward
pump a minimum of 1/4" per foot.
This will prevent trapping air in the
lines.
ELECTRICAL CONNECTIONS
The voltage of power supply must
match the voltage of the pump. Above
ground well pumps covered in this
manual have dual voltage motors pre-
set at the factory to 230 volts. The
motors can be converted to 115 volts by
turning the voltage selector to the
desired voltage (See Figure 6). Use a
needle nose pliers to pull the selector
out approximately 1/4”, rotate and
then reinsert in correct position.
Connect the pump to a separate electri-
cal circuit with a dedicated circuit
breaker. Refer to the electrical specifi-
cations in the Wiring Chart for recom-
mended circuit breaker and wire size.
Install and main–
tain wiring for this
pump in accordance with the National
Electrical Code and all applicable local
codes.
The motor must be grounded by con-
necting a copper conductor to the
grounding screw provided within the
wiring compartment in the pressure
switch.
The field wiring compartment for the
jet pump is inside the pressure switch
housing. There is only one proper
ground screw on the unit. The screw is
located under the pressure switch
cover, painted green and is identified
as GRD. The ground connection must
be made to this terminal (Figure 7).
! WARNING
Refer to the wiring diagram located
under the cover of the pressure switch
(Figure 7).
To attach AC power to the switch,
loosen the screw holding the cover
onto the switch and remove the cover.
Loosen unused ground screw and
attach the exposed end of the ground
wire between the screw head and the
pressure switch body, then tighten.
Loosen the top two screws on the pres-
sure switch and retighten with the AC
power leads captured under the screw
heads. Reattach the pressure switch
cover and tighten the screw.
CONNECTION TO WATER SOURCE
DRIVEN WELL
1. Drive the point several feet below
the water table.
NOTE: A packer-type foot valve can be
installed in the well (Figure 8). This
type of foot valve allows the well pipe
to be filled with water when priming
and makes the inlet pipe much easier
to test for leaks. Follow the manufac-
turer’s instructions when installing the
packer-type foot valve.
