Pressurized (Bladder) Storage Tank (if equipped)
This chart shows the storage capacity for pressurized storage tanks at various precharges.
To determine this volume:
1.
First locate the line that represents the air precharge of
the tank.
2.
Find the point on the horizontal axis at the bottom of
the graph that represents the total pressure (air plus
water) in the tank. Move vertically to the appropriate
air precharge line found in step 1.
3.
Move horizontally to the left axis and read the percent
of "maximum total volume" in the tank under the
above conditions. Multiply this percentage by the
maximum total water volume to determine the volume
of water in the tank.
Bladder Tank Fill and Test
With the product line connected to the tank and with the system running, close the inlet valve to the tank. The tank pressure gauge
should start to rise and the system should shut off when the gauge reads about 65 psi. Opening the tank valve will allow the pressure
to drop. The system should turn on when the pressure falls below 40 psi.

2.
The tank pressure gauge should start to rise and the system should shut off when the gauge reads about 65 psi .
Opening the tank valve will allow the pressure to drop. The system should turn on when the pressure falls below
40 psi.
3.
After the pressurized tank reaches 65 psi, the system will go into stand-by mode (the pump will turn off).
4.
Drain the tank using the flush valve on the postfilter of the filtration array.
5.
Allow the tank to refill. Proceed to Blending Valve Adjustment, if required.
