Use

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.

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 setting +10. 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.
