intervals.

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.
AIR FILTER MAINTENANCE
In order to ensure optimum compressed air quality the filter element
should be replaced as follows. (Used filter elements must be disposed
of in accordance with local regulations.)
Use only genuine Ingersoll Rand replacement elements.
