Caution
The freezer should be in the charge of a specially assigned person. He/she checks
and records the freezer’s running condition (every 2-4 hours). And, in case of a fault
or power failure, the temperature inside the freezer will rise. If the fault cannot be
cleared in a short time, please take out all articles stored in the freezer and put them
in another freezer meeting their temperature requirement to avoid deterioration.
Before putting articles to be stored in the freezer, make sure that the freezer’s
temperature range meets the temperature requirement of these articles. Otherwise
they may deteriorate because the freezer cannot reach the required temperature,
resulting in loss.
Due to the inertia of refrigeration, there is a certain difference between actually
displayed temperature and set temperature (the lower set temperature, the less
temperature difference and vice versa). It is normal.
Prohibition
All low-temperature freezers are storage equipment. It is strictly prohibited to put
too many relatively hot items in the freezer at a time; otherwise the compressor will
keep working for a long time without stop and be damaged easily and the
temperature will not reduce. Be sure to put articles in batches and make the
temperature inside the freezer reduce in steps to the desired temperature.
Do not accelerate defrosting by using any tool or method not approved by the
freezer’s manufacturer.
Do not damage the refrigerating loop.
Dot use any appliance not approved by the freezer’s manufacturer in the freezer.
Operation after power failure
The freezer can memorize the settings. In case of power failure, the freezer will still
operate with the parameters set before power failure when power supply resumes.

The freezer’s temperature is set and
adjusted as follows:
1.
Unlocking
When the “Lock” indicator lights up, all keys except the “
” key are locked.
Press and hold the “
” key for 5s, the display area for internal temperature will
show F0 and “0” will flash; then press the “ ” key, the display area for internal
temperature will show F1; finally press the “Set” key, the keyboard will unlock
and the display panel will show internal temperature. If any key is pressed in 10s,
the keyboard will automatically be locked.
2.
Temperature setting
In initial power-on state, press the “Set” key, the display screen will show L0 and
“0” will flash; press this key again, the display screen will show the default
temperature setting (i.e. -30
℃
) and the second digit will flash. (If the freezer is
not used for the first time, the display screen will show the temperature set last
time) Adjust the freezer to the desired temperature by pressing the “
” key to
switch the flashing digit and pressing the “ ” key to change the value of current
flashing digit, and then press the “Set” key to confirm and memorize the
temperature setting. Temperature setting range: (-20
℃
~-45
℃
)
3.
High temperature alarm setting
After unlocking, press the “Set” key, the display screen will show L0 and “0”
will flash; press the “ ” key, the display screen will show L1; press the “Set” key
again, the display screen will show the default temperature setting for high
temperature alarm with the second digit flashing (the default temperature setting
for high temperature alarm is internal temperature s10. Note: When
showing the temperature, the “
” sign followed by digits means the “+” sign)
and then adjust the temperature setting by pressing the “
” key to switch the
flashing digit and pressing the “ ” key to change the value and sign of current
flashing digit; after finishing setting, press the “Set” key to memorize the setting.
Temperature setting range for high temperature alarm: maximum displayed
temperature ≥ set temperature for high temperature alarm - set temperature ≥5
℃
;
otherwise use the default setting.
4.
Low temperature alarm setting
After unlocking, the display screen will show L0 and “0” will flash. Press the
“ ” key twice, the display screen will show flashing L2; press the “Set” key, the
display screen will show the default temperature setting for low temperature
alarm with the second digit flashing (the default temperature setting for low
temperature alarm is internal temperature setting -10), and then adjust the
temperature setting by pressing the “
” key to switch the flashing digit and
pressing the “ ” key to change the value of current flashing digit; after finishing
setting, press the “Set” key to memorize the setting. Temperature setting range
for low temperature alarm: minimum displayed temperature ≤ set temperature for
low temperature alarm - set temperature ≤-5
℃
; otherwise use the default setting.
