Change the TK Fresh Delay

Note The fresh air exchange time delay should be established by the shipper.

The TK Fresh delay setting keeps the fresh air vent closed for a preset time when the unit starts. This allows faster product temperature pull-down. The TK Fresh delay can be set from 1 to 72 hours in 1-hour increments. Refer to (Change the TK Fresh Delay) for the procedure to set the delay.

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