Notes:
• A defrost duration is the period of time that the refrigeration system spends in defrost mode. During the defrost
duration, the ice melts off the evaporator coil. A defrost duration may include drip time at the end of the
duration.
• A defrost interval is the time between the start of a defrost duration and the start of the next defrost duration.
