16.0 BLADDER INTEGRITY TEST
With the schematics for valve descriptions and the air test equipment for your reference, the air integrity test of the blad-
der is as follows:
1. Isolate the tank from the water system by closing the water supply valve #2 and the concentrate valve #1.
2. Attach a garden hose to water drain valve #6, open, and terminate to the drain.
3. Slowly open water vent valve #4 and concentrate vent valve #5.
Note: Continue with the following steps when the water has completely drained.
4. Perform concentrate level check. (Refer to page 15)
5. Thread the air test equipment (see enclosed schematic) to concentrate vent valve #5. Connect an air supply to
the air regulator.
Note: Important to use 3-lb pressure gauge!
6. Begin filling the bladder with air until pressure gauge reads 1 PSI maximum. Do not be alarmed at the air escap-
