depicts normal purge pump-out times, small leaks, and
large leaks based on chiller tonnage.
If the purge pump-out time is in the small leak region,
then a leak check should be performed and all leaks
repaired at the earliest convenience. If the purge pump-
out time is in the large leak region, a thorough leak
check of the unit should be performed immediately to
find and fix the leaks.
