START-UP OF UNIT
The following procedure should be adhered to for initial
<D Connect unit to dedicated power supply. Do not put any product in the unit at this time.
®When the power is initially applied, the audible alarm may sound. Set the BUZZER switch to OFF to silence the alarm.
@ Set the desired temperature.
@Check that the chamber temperature has reached to the desired temperature.
@When you are satisfied that the unit is working correctly, begin slowly placing product into the chamber to minimize the temperature rise.
Handling of the containers
Arrange containers not to disturb air circulation in the unit. Disturbance of air circulation may cause freeze of containers or incline of temperature.
<D Air intake vent
Avoid the disturbance of air circulation in the unit by containers. Disturbance of air circulation may causes freeze of containers or incline of temperature.
®Air exhaust vent
Do not disturb the exhaust air port by putting containers near the exhaust air port. Containers near the exhaust air port may freeze when the unit runs with low temperature (less than 5°C).
Note:
Never store the material of corrosive such as acid or alkaline of which container is not sealed up completely. It may cause poor cool by refrigerant leakage resulted from corrosion of the evaporator.

There are two types of defrost cycles present in this blood bank refrigerator, and both cycles occur automatically.
1.Cycle defrost
To keep the temperature stable inside the chamber, the refrigeration compressor is cycled on and off. During the "off'periods any frost which has accumulated on the refrigeration coils is melted by energizing a small heater, this will not have any discernable effect on the
chamber temperature.
2.Forced defrost
When ambient humidity is high, or a large amount of damp product is being stored inside the refrigerator, there is a possibility that cycle defrost may not be enough to remove all of the frost on the refrigeration coils. In this case, a forced defrost cycle will be initiated. While the unit is operating under a forced defrost cycle, the defrost lamp on the control panel will be lit. Once the forced defrost cycle is complete,
normal operation will resume. The chamber temperature rises to about 10°C during the defrosting.
