Aircel VF Series - Models 10 - 1200

Automatic Drain Valve Adjustments

The automatic drain valve supplied is standard on the
separator and should open regularly and discharge
any accumulated water into the drain line. The
period between openings varies with the dryer and
operating conditions (electronic type). To minimize
air losses, the timer should be adjusted to open
the drain solenoid just long enough to discharge
the accumulated condensate. The factory sets the
automatic drains to open for 7 seconds about every 7
minutes. If more than two seconds of dry air comes
out at the end of every discharge cycle, reduce the
open time (seconds) or increase the interval of the
discharge (minutes) to minimize air loss. If liquid
is still being discharged when the discharge cycle
stops, increase the open time (seconds) or shorten the
interval of discharges (minutes) so it discharges more
often.

Operating Procedure

After the initial startup, the dryer operation is
completely automatic. To understand the details of
the operation, see the flow diagram on pages 7 and 8.

Air Cooled Condenser Requirements

Cooling air must be drawn from a clean source to
reduce dust and dirt accumulation on the condenser
coils. Air temperature should not exceed 100°F
(38°C).
