If the inside temperature arises because of the failure of the freezer, which cannot be
solved within short time, please remove the sample to avoid the potential damage
Before putting samples in the freezer to be stored, first check that the freezer's
temperature for the samples conforms with the temperature that is required for the
samples, in order to prevent the samples to be stored from getting damaged or lost due to
the freezer not attaining the temperature required.
Because it takes time for the refrigeration temperature to reach the stored samples, there
is normally a temperature discrepancy between the actual shown temperature and the set
point. This is a normal phenomenon. The lower the set point is, the smaller this
temperature discrepancy becomes.
All ultra low temperature storage units are low temperature storage equipment. It is
prohibited to load an excessive amount of samples into the unit at one time. The
compressors run for a long period of time without stopping. The freezer temperature may
not decrease, and the compressors can become overheated. Samples must be loaded in
batches, and while incrementally decreasing the temperature setting. The process should
be repeated until the final 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 non manufacturer-approved electrical components in the freezer.
Operation after a Power Outage
The Haier ULT freezer control setting is stored in its memory system. Should there be a power
outage and recovery, the unit can resume its operation based on the previous settings.
In the event of a power outage and recovery, be sure to wait for at least 5
minutes before turning the unit on again to avoid damaging the compressors
and refrigeration system.
If the unit is not in use for a long period of time, make sure the power cord is
unplugged. Deteriorated insulation of the power cord may lead to electric
shock or fire.
If the freezer is not in use in an area without any supervision, please make
sure children will not approach the freezer and the doors should not be closed.

and then the buzzer rings once. Here cancellation is done. If the password entered is wrong three
time in succession, exit and lock it and re-display the temperature inside the box.
Exporting USB data
1. In unlocked mode, insert the USB flash drive. The temperature display shows USB which means
data is being exported.
2. When the temperature display shows ALL, exporting of the data is finished, please remove the
USB flash drive.
The system memory can save data for 10 years.
