WATER-LOGGED TANKS
CONVENTIONAL TANKS
When a tank system has an inadequate
ratio of air and water, the pump will
start and stop often and erratically.

3. Prime the pump.
4. Reconnect power.
As the pump refills the tank, the air vol-
ume control supplies the tank with the
correct air to water ratio. The pump
will then shut off at desired pressure. If
tank water-logs again, examine air vol-
ume control and replace if necessary.
PRE-CHARGED TANKS
If a pre-charged tank becomes water-
logged, the bladder is probably leaking
or broken.
1. Test the tank by depressing the air
valve. The valve will discharge water
if the bladder is broken.
2. If bladder is broken, replace tank.
Once a tank bladder is ruptured, the
tank should be replaced. Repairing the
bladder is not recommended, and may
cause further problems such as: repeat-
ed water-logging, debris in pipes and
clogged discharge in tank.
AIR PRESSURE CHECK FOR PRE-
CHARGED TANKS
Small amounts of air loss is normal in
any tank. To prevent failure and prop-
erly maintain a pre-charged water tank,
check the pressure on a yearly basis.
1. Disconnect power to pump.
2. Open a faucet nearest the tank and
allow all water to drain from the
tank.
3. Measure the tank pre-charge at the
valve stem using a tire gauge.
4. If necessary, adjust the pre-charge
with an air pump: Precharged pres-
sure for the JSU50 pump is
18-20 psi.
5. Prime the pump.
6. Reconnect power.
7. Close faucet.

2. Drene todas las tuberías hasta un
nivel por debajo de la línea de
congelamiento.
CÓMO DRENAR EL TANQUE
Se pueden drenar los tanques
convencionales al abrir una salida en el
punto más bajo del sistema. Retire un
tapón o el control de volumen de aire
para ventilar el tanque.
Los tanques pre-cargados fuerzan
prácticamente toda el agua fuera del
tanque cuando se libera la presión del
sistema. No se necesita drenaje.
TANQUES INUNDADOS
TANQUES CONVENCIONALES
Cuando un sistema de tanques tiene
una proporción inapropiada de aire y
agua, la bomba empezará a funcionar y
dejará de funcionar frecuente e
irregularmente.
1. Desconecte la energía eléctrica de la
bomba.
2. Abra la llave en la parte más baja
del sistema para liberar toda la
presión.

3. Cebe la bomba.
4. Vuelva a conectar la energía
eléctrica.
A medida que la bomba vuelve a llenar
el tanque, el control de volumen de
aire proporciona al tanque la
proporción correcta de aire y agua.
Luego la bomba se apagará en la
presión deseada. Si el tanque se vuelve
a inundar, revise el control de volumen
de aire y cámbielo si es necesario.
TANQUES PRE-CARGADOS
Si un tanque pre-cargado se inunda,
quizás la bolsa tenga una fuga o esté
rota.
1. Pruebe el tanque desenroscando la
válvula de aire. La válvula
descargará agua si la bolsa está
rota.
2. Si la bolsa, está rota, cambie el
tanque.
Cuando la bolsa de un tanque esté
rota, se deberá cambiar el tanque. No
se recomienda reparar la bolsa pues
puede causar problemas más adelante,
por ejemplo: continuas inundaciones,
desechos en las tuberías y descarga
obstruida en el tanque.

VERIFICACIÓN DE LA PRESIÓN DE
AIRE PARA TANQUES
PRE-CARGADOS
Es normal que haya pequeñas pérdidas
de aire en cualquier tanque. Para
prevenir cualquier falla y mantener
correctamente un tanque de agua pre-
cargado, verifique la presión
anualmente.
1. Desconecte la energía para
bombear.
2. Abra la llave más cercana al tanque
y deje drenar toda el agua del
tanque.
3. Mida la pre-carga del tanque en el
vástago de la válvula utilizando un
medidor de presión de
neumáticos.
4. Si es necesario, ajuste la pre-carga
con una bomba de aire; la presión
pre-cargada para la bomba JSU50 es
1,24-1,38 bar.
5. Cebe la bomba.
6. Vuelva a conectar la energía.
7. Cierre la llave.
