Setting the timer

□
To set the timer knobs, first remove the caps
(D) from the front of the timer.
□
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 (.5
seconds to 10 seconds) from the 1/4 in. or 1/2
in. condensate outlet port.
□
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.
□
To check the "time on" setting to see if it is
draining long enough, press the "TEST" button.
The compressor will drain the condensate for
the length of time set. Adjust the "time on"
setting accordingly.
□
Reattach the caps (D) to the timer knobs when
the timer is set.
