Note:

The displayed temperature represents the temperature sensed by a thermal sensor attached to the monitor bottles mounted to the upper and lower portion of the chamber.

The displayed temperature may not always be at 4 oC. The chamber probes are representative of high and low average temperatures within the chamber.

Defrost cycles

There is no need for routine defrosting of the unit as this occurs automatically as follows:

1. Cycle defrost

To keep the chamber temperature stable, the refrigeration compressor is cycled on and off. During offperiod any frost which has accumulated on the evaporator is melted by energizing a defrost heater. This will not have any discernible effect on the chamber temperature.

2. Forced defrost

When the ambient humidity is high, or a large amount of damp product is being stored inside the chamber, there is a possibility that cycle defrost may not be enough to remove all of the frost on the evaporator. In this case, a forced defrost cycle can be initiated.

When the unit is operating under a forced defrost cycle, the current chamber temperature and dFis displayed alternately on the digital temperature display.

Once the forced defrost cycle is completed, normal operation resumes.

The chamber temperature of blood bag (400mL) rises about 1 to 2 oC during the defrosting.
