Operation after Power-off
The set value is memorized by the equipment. After recovery from a power failure, the
equipment will resume operation with the setting parameters before the power failure.
WARNING
Ì
If the biomedical freezer is unplugged or the power to the
biomedical freezer is interrupted, do not restart the biomedical
freezer for at least 5 minutes to avoid damage to the compressor
or system.
WARNING
Ì
When the biomedical freezer is not in use for a long period,
unplug the power plug and turn off the battery switch (applicable
to biomedical freezers with batteries) to prevent electric shock,
electric leakage, or fire due to the deterioration of the power
cord.
Ì
If the biomedical freezer is to be stored unused in an
unsupervised area for a long period, ensure that children do not
have access to the biomedical freezer and that doors cannot be
closed completely.
y
The product shall be managed by a specially-assigned person to check
the operation and make records every day (it is recommended to record
the inspection once every 2~4 hours). In case of failure or shutdown, the
temperature in the biomedical freezer will rise. If it cannot be repaired in
a short time, the articles shall be transferred to other places that meet the
temperature requirements for storage to avoid damage to the articles.
y
This product is a biomedical freezer. Please confirm in advance that the
temperature required for the stored articles is consistent with the tem-
perature range of the biomedical freezer to avoid damage to the stored
articles due to mismatch of the temperature range.
y
Due to the inertia of refrigeration, the temperature and humidity displayed
for this product may differ from the actual temperature and humidity in-
side the chamber, which is a normal phenomenon.
y
Since all biomedical freezers are storage equipment, it is strictly prohib-
ited to put too many relatively hot items at one time, which will cause the
compressor to not stop for a long time, the temperature will drop slowly
and affect the service life of the compressor. The items must be put in
batches to allow the temperature to decrease by steps until the required
temperature is reached!
y
Do not damage the refrigeration circuit.
y
Do not use electrical appliances without production permits inside the
biomedical freezer.
y
No mechanical tools or other means without the manufacturer's permis-
sion shall be used to accelerate the defrosting process.
CAUTION
Ì
Since the ambient temperature has a large impact on the
equipment, the equipment may not operate normally if the above
environmental requirements cannot be met. Please improve the
environment before using the equipment. The equipment has an
intermittent operation working system.
Preparations before Use
1. Remove all transport packaging materials and belts.
2. Counting the accompanying accessories. Check the items in the box against the
contents of the packing list. If there is any discrepancy, please contact with after-
sales service in time.
3. The placement conditions shall be such that clearances of at least 30cm are
reserved around the biomedical freezer for ventilation and heat dissipation.
4. Rotate the horizontal supporting feet clockwise with a wrench or manually to extend
downward so that they are supported on the ground to ensure that the biomedical
freezer does not move when used.
5. Take out the back bracket in the biomedical freezer, and fix the back bracket on the
back plate with screws.
6. Take out the handle, align the handle with the hole on the right side of the door, fix
the door handle to the door with an electric screwdriver, and then fasten the handle
trim cover to the upper and lower ends of the handle.
WARNING
Ì
Place the plastic packing bags in a place not accessible to
children to avoid suffocation accidents.
First Power-up
Follow the steps below when using the equipment for the first time:
1. After the equipment is placed and leveled and cleaned, it shall be left for more than
24 hours before it is powered on to ensure normal operation.
2. Connect the power cord to a dedicated socket of suitable specification under no-
load condition.
3. After the power supply is turned on, turn on the power switch of the equipment first;
if the equipment is equipped with a battery, turn on the battery switch again.
4. Set the required temperature, do not put anything in the empty biomedical freezer, power
on and start up, check whether the operating temperature of the equipment reaches the
required temperature, observe the normal startup and shutdown of the equipment for
more than 24 hours, and demonstrate that the performance of the biomedical freezer is
normal.
5. Store items in batches, not exceeding 1/3 of the chamber volume at a time. Ensure
that the equipment is shut down and operates normally after being switched on and
off for more than 8 hours before placing the next batch of items.
6. Avoid opening the door during the cooling process as much as possible, otherwise
it will cause the temperature to rise.
