Change the AFAM Delay
NOTE: The fresh air exchange time delay
should be established by the shipper.
The AFAM delay setting keeps the fresh air vent
closed for a preset time when the unit starts. This
allows faster product temperature pull-down. The
AFAM delay can be set from 1 to 72 hours in
1-hour increments.
WARNING: The vent door and motor
actuator arm move immediately when the
F4
key is pressed to turn the AFAM system
to Demand, Units or Off. Keep hands and
tools away from the air exchange system
components to prevent personal injury or
unit damage.
