At system start-up, when a purger is initially installed in
a system that has fewer purge points than are available
on the purger (e.g., an APP08 used on system that has 5
purge points), the unused purge points must be set to 0.
The water collection parameters can not be changed and
are for information only. The counts indicate the time
in seconds that the water concentration as measured
by the water concentration sensor exceeds the
concentration set point. The concentration of water in
the purger evaporator must exceed 25% for 10 minutes
(600 seconds) continuously before the purge will enter
