Stop the stopwatch when the purging indicator stops flashing.
Check stopwatch timing to verify that the actual purge time is equal to or greater than the required purge time.
Note: The recorded purge time must never be less than the required purge time.
The system is now operating correctly in leakage compensation mode.
If the system has not performed as expected, check the installation thoroughly and ensure it has been carried
out according to the instructions.
If an obvious problem has not been highlighted and corrected, follow the procedures in the
Fault Finding
section.
If all checks have been carried out and the system still does not perform as expected, contact your local
distributor or Expo Technologies.
