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. Refer to (Change the AFAM Delay) for the procedure to set the delay.

Note During unit startup, the AFAM delay prevents the
AFAM door from opening until the delay times out. The AFAM delay prevents
the AFAM door from opening due to the AFAM Rate or CO2 system settings.
