The buzzer and remote alarm will be activated again after certain suspension if the alarm condition is continued. The suspension time can be set by following the procedure shown in the Table 6 below.
DEFROSTING Refrigerator The following 2 kinds of defrost methods are adopted for the refrigerator, which control defrosting automatically. 1. Cycle defrost To keep the temperature stable inside the chamber, the refrigeration compressor is cycled on and off. During “off” periods any frost which has accumulated on the evaporator is melted by energizing a heater. This will not have any discernible effect on the chamber temperature.
MAINTENANCE WARNING Always disconnect the power supply to the unit prior to any repair or maintenance of the unit in order to prevent electric shock or injury. Ensure you do not inhale or consume medication or aerosols from around the unit at the time of maintenance.
OPTIONAL COMPONENT Automatic temperature recorder To record the chamber temperature, an optional automatic temperature recorder is available.
