TIMER SETTINGS
The "time off" setting determines the interval between
cycles from 30 seconds to 45 minutes�� The "time on"
setting determines the actual time the compressor drains
condensate��
The timer's cycle rate and drain opening time should
be adjusted to open just long enough to discharge the
condensate�� The timer is properly set when it opens
and discharges condensate and then vents air for
approximately one second before closing�� Adjustments
may be made depending on many factors, including
humidity and duty cycle��
