Air pressure test (leak testing)
1. Using the "Hold/Sample/Cycle" button on the lower left corner of the keypad, press until the pump is in
the discharge cycle, as indicated on the LCD display by an arrow.
2. Allow the bladder to fully discharge, then observe the pressure reading on the gauge.
3. Leaving the controller in discharge mode, turn off the air source but DO NOT disconnect the air source
supply hose.
4. Observe the pressure gauge - it should remain steady for at least a minute (a very slow decay in the
pressure is acceptable)
5. Observe the pump discharge tubing - there should be no discharge of water or air bubbles.
