• A person shall be specially assigned for daily check and record of the product operating
conditions, in case the temperature inside the bin is on the high side or on the low side, just
transfer the articles to the other freezers till the fault is removed and then replace back the
articles.
• Before putting any article in the freezer, please confi rm that the temperature required for
the article is consistent with the temperature range of this product in advance, in order not to
damage the article due to the failure of this product to reach to the temperature required for the
article.
• The indicated temperature of this product may have a certain difference with the actual
temperature inside the bins due to refrigeration inertia, this is normal.
• The temperature within the topside drawer of freezer would be relatively higher than that in
other drawers, so, for any article with strict requirements for temperature should be placed in
other drawers as possible.
• All the freezers are of storage equipment, and it is strictly forbidden to put excessive articles
that are relatively too hot in one go, this will cause long time of running of the compressor
without stop, slow drop of temperature, thus affecting service life of the compressor, the articles
must be put in batches so that the temperature drops in steps till the required temperature is
reached.
• Do not use any mechanic tool or other means without permit from manufacturer to accelerate
the process of defrosting.
• Do not spoil the refrigerating circuit.
• Inside the freezer, do not use the electric appliance without production permission.
The freezers can retain their operation parameters when there is power outage. When the power
recovers, they will continue to operate based on the saved parameters.
• Under outage or other fault, the freezer would stop and the inner temperature
will rise. If the power could not be recovered in a short time, please take out the
articles and store them by other means, in order to avoid any loss caused by article
damage.
• Once the power of the freezer is cut off, wait for over 5 minutes before it is
reconnected so as not to damage the compressor or the system.
• Pull out the power plug when the freezer is not in service for a long time and
turn off the battery switch if applicable, so as to prevent electric shock, leakage of
electricity or fi re due to aging of the power cord.
• If the freezer is left unused for a long time in an unattended area, make sure
that children will not approach the freezer and the freezer door can not be closed
completely.
Operation after a power failure

Alarm
• When the temperature captured by sensor is higher than+5
℃
(or higher than the setting value of
high-temperature alarm), "AH" and temperature will be alternately shown; when the temperature
captured by sensor is lower than -5
℃
(or lower than the setting value of low-temperature alarm), "AL"
and temperature will be alternately shown.
• For any short circuit, open circuit, or fault, or incorrect connection happens on the temperature
sensing probe, "Err" will be shown, and when the sensor's temperature is higher than 85
℃
, "EHi"
will be shown, and when lower than -50
℃
, "ELo" will be shown. At the same time, the beeper for
temperature controller will be initiated, and corresponding alarm parameter (such as Err, Ehi, Elo) will
be shown on the screen correspondingly, as well as the alarm mark (without display of temperature).
• If the temperature sensing probe is judged for error, power should be cut off, and
the connection of sensing probe should be checked fi rstly.
• If any internal code is shown when the user is adjusting the temperature
controller, please wait for 1 minute until the temperature is shown again, in order to
prevent from any fault due to any change of control parameter.
• Under alarm, the beeper alarm could be ceased by pressing any key, and the fl ashing alarm and
remote alarm will not be ceased).
• If the alarm condition is still available, the beeper alarm will be recovered automatically 30 minutes
after ceasing.
