SLOW DISCHARGE

• Throttle the back pressure valve assembly so that it takes about 10 seconds for the pump to discharge
  on each cycle.

SLOW FILL

• Throttle the refill rate valve assembly so it takes about to fill and discharge.

WATER LEAK TEST

• While cycling the pump, close the backpressure valve assembly when the pump begin discharging.
• Lift the pump out of the tube and check for significant water leaks on the bottom of the casing, a few drops are acceptable.
•  After ensuring that there are no significant water leaks, open the backpressure valve assembly so the pump can discharge in the tank.

PUMP REMOVAL

• After the pump has completely discharge, close the isolation valve on the filter/regulator until the gauge reads “0”.
• Disconnect the air and exhaust hoses.
