Precautions for Use
• When the biomedical freezer is running, the left and right side walls of the biomedical freezer may
be heated, which is not a fault. In order to prevent condensation around the biomedical freezer
housing, the space is lled.
• Before putting items into the equipment, conrm that the temperature in the storage chamber has
reached the set temperature, and then load items in batches. Do not put in items for more than
1/3 of the volume of the chamber at a time to prevent its temperature from rising too much.
• The equipment temperature display is the temperature at the temperature sensor in the storage
chamber. When the equipment is initially running, the displayed temperature is somewhat different
from the actual temperature at the center of the equipment. However, as the equipment operates
to a stable state, the displayed temperature will gradually approach the actual temperature.
• The equipment chamber is designed with a testing hole so that the items inside the chamber can
be led out for testing. After the testing line is pulled out, it is necessary to plug the testing hole
again with thermal insulation material; otherwise, the temperature inside the biomedical freezer
may not reach the set temperature and cause condensation around the outside of the hole (appli-
cable to biomedical freezers with testing holes).
• Please use diluted neutral cleaner to clean the equipment. Do not use brushes, acid, gasoline,
soap powder, polish, or hot water to clean this equipment, otherwise it may damage the painted
surface and plastic rubber parts. Special care must be taken not to use volatile solvents such as
gasoline to wipe plastic and rubber parts.
• When the biomedical freezer is not in use for a long period, cut off the power supply and turn off
the battery switch.
• If the biomedical freezer is not started again for a long time, a low battery level may occur. After
the battery switch is placed at "ON", the battery can be charged, and the biomedical freezer can
run continuously for about one week to charge the battery (applicable to models with batteries).
• Please minimize the times of opening the door during each access to the items, so as not to
cause great uctuations in the temperature and humidity in the chamber.
• After the door is opened, the temperature in the biomedical freezer will rise sharply in a short time,
which is normal, and it will return to the set temperature after the door is closed.
• After the biomedical freezer has been running for a period of time, a layer of frost may form on the
inner wall, caused by sharp tools such as an ice pick, knife, or screwdriver. The inner wall shall not
be scratched or damaged, or the biomedical freezer will fail.
• Before defrosting, the frozen items in the biomedical freezer shall be taken out and placed in an
appropriate suitable format for storage, so as not to damage the items due to an increase in tem-
perature.
• There are many refrigeration coils in the biomedical freezer. The frost that forms on these coils
should be removed by sharp tools such as an ice pick, knife, or screwdriver. The inner wall shall
not be scratched or damaged, or the biomedical freezer will fail.

start up the unit, monitoring whether the operating temperature reaches the required level. Observe
the normal startup and shutdown of the equipment for more than 24 hours to conrm that the freezer
is functioning properly.
Load Items Gradually:
Load items in batches, not exceeding 1/3 of the chamber volume at a time. Ensure that the unit is
shut down and operates normally after being switched on and off for more than 8 hours before plac-
ing the next batch of items.
Minimize Door Opening:
Avoid opening the door during the cooling process as much as possible, as this will cause the tem-
perature to rise.
11
Operation After Power-Off
The set temperature is retained by the equipment. After recovery from a power failure, the equipment
will resume operation with the previous settings.
Warning:
Restarting the Freezer: If the biomedical freezer is unplugged or if the power is interrupted, do not re-
start the freezer for at least 5 minutes to avoid damaging the compressor or system.
Warning:

turn off the battery switch (if applicable). This helps prevent electric shock, electric leakage, and dete-
rioration of the power cord. If the freezer will be stored unused in an unsupervised area for a long time,
ensure children do not have access, and make sure the doors are fully closed.
Maintenance and Management
Regular Checks: Assign a responsible person to regularly check the operation and record tempera-
tures (recommended every 2-4 hours). If there is a failure or shutdown, the temperature inside the
freezer will rise. If the issue cannot be resolved quickly, transfer stored items to a suitable location to
prevent damage.
Conrm Temperature Range: This freezer is designed for biomedical use. Ensure that the storage
conditions match the temperature requirements of the items. Avoid opening the door frequently to
maintain a consistent internal temperature and protect stored items.
Temperature Display: The temperature and humidity readings may differ between the display and the
actual chamber conditions. This is normal and expected.
Important Usage Guidelines
Avoid Frequent Door Openings: Because the freezer is designed for storage, it’s essential to minimize
the frequency of door openings. Repeated opening and closing will cause the internal temperature to
rise and put stress on the compressor, potentially leading to longer cooling times.
Do Not Damage the Refrigeration Circuit: Never damage the refrigeration system as it could lead to a
malfunction.
Use Only Approved Appliances: Only use electrical appliances within the freezer’s storage compart-
ment if they are approved by the manufacturer.
