TANKS - PRE-CHARGED STORAGE
The well pump must be mounted to either a pre-charged or conventional type tank. One 20 gallons tank is recommended,
the bigger tank the better.It is best to have this in place before installing the pump. For best performance of the pump, it
is recommended that you use a diaphragm pressure tank (sold separately). A pre-charged storage tank has a flexible
bladder or diaphragm that acts as a barrier between the compressed air and water. This barrier prevents the air from
being absorbed into the water and allows the water to be acted on by compressed air at initially higher than atmospheric
pressures (pre-charged). More usable water is provided than with a conventional type tank.
Air pressure in the tank must be 2 psi lower than the "cut-in" of the pressure switch.
NOTE: The pump has a 30/50 psi pressure switch, which means the "cut-in" is 30 psi; therefore, the tank needs to be set
to 28 psi. To check the pressure in the tank, use a tire pressure gauge (not included). If more air is needed, add air to the
tank with a tire pump or air compressor. If less is needed, bleed out some air.
CAUTION: In order for the pump and tank to operate properly, the pressure tank needs to be drained of all water
BEFORE INSTALLING THE NEW PUMP. After draining, if you are using the supplied 30/50 psi pressure switch at the
pre-set settings, add or adjust the air pressure in the tank to 28 psi of pressure BEFORE start up.
