If the freezer temperature warms up, and the issue can’t be resolved within a short time, please transfer the
stored products to another freezer to avoid potential damage.
•
Before placing samples in the freezer for storage, check the freezer temperature to make sure the
temperature meets the storage requirement for the samples. This is to prevent any potential damage to the
samples due to incorrect storage temperature.
•
Since it takes time to remove lower the temperature of the stored product, there can be a
difference between
the set temperature and the displayed temperature. This difference will get smaller as the set point is lowered.
Samples must be loaded in batches
, while gradually decreasing temperature setting. The process should be
repeated until the fin
al temperature is reached.
•
Do not use any unauthorized mechanical tools or other means to accelerate the defrosting process.
•
Do not damage the refrigeration circuit.
•
Do not use any unapproved electrical components in the freezer.
It is not recommended to load excessive amounts of samples into the unit at one time
. Overloading may result
in inadequate performance. The freezer and the compressors can become overheated and malfunction.
