Defrosting Inside Biomedical Freezer
Frosting may cause a gap between the biomedical freezer and the door sealing strip,
resulting in poor refrigeration. The inner door shall be defrosted with an ice shovel
attached to the biomedical freezer. The following steps are natural defrosting.
1. Shut down the auxiliary cooling device if any.
2. Remove items from the biomedical freezer and transfer them to an
environment suitable for storage.
3. T
urn off the power switch
4. Open the outer and inner doors to allow the biomedical freezer to open
naturally for a period of time for defrosting.
5. Dry the accumulated water at the bottom of the biomedical freezer with a
piece of dry cloth.
6. After cleaning the biomedical freezer and inner door, restart the biomedical
freezer.
7. Put the items back into the fully cooled biomedical freezer.
8. If there is an auxiliary cooling device, restart the device.
CAUTION
Do not use knife, screwdriver or any other tool with a sharp edge to
defrost.
Equipment out of Service
Out of service: 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.
Scrap: The scrapping disposal of the biomedical freezer shall be carried out by
corresponding professionals. In order to prevent something like
suffocation, the
biomedical freezer doors must be removed.
Optional Parts
Temperature Recorder
Please refer to the Temperature Recorder Instructions provided by the temperature
recorder for use.
CAUTION
Please install the temperature recorder by professional technicians
or after-sales personnel.
WARNING
Please cut off the power supply before installing the temperatur
e
recorder; otherwise, electric shock or fire may occur
.

Fault
Troubleshooting Method
Biomedical freezer
does not work
Is the power circuit breaker normal?
Is the power voltage too low?
Is the power switch off?
Is the fuse blown?
Poor cooling
Is the ambient temperature too high?
Is the door closed tightly?
(The frost between the biomedical freezer and the door seal-
ing strip may damage the door sealing performance)
Is the air inlet dirty and blocked?
Are the condenser and filter screen dirty and blocked?
Is the temperature set correctly?
Is the biomedical freezer away from direct sunlight?
Is the biomedical freezer close to the heat source?
Are the rubber hole cover and insulation material of the test
through hole properly placed?
Is a large amount of high temperature articles placed in the
biomedical freezer for a short time?
Excessive noise
Is the biomedical freezer installed on a solid and flat ground?
Are other items contacted to the biomedical freezer housing?
Is the base of the biomedical freezer leveled?
Note: If the fault cannot be eliminated after the above items are checked, or the fault is
different from the above list, please contact the after-sales personnel.
