1.3 Precautions for use

• When the device is running, the front part of the device may get hot. This is not a
malfunction: In order to prevent dew condensation around the case body, a heated anti­condensation tube is installed in the cryogenic storage case.

• Before putting the items in the device, please make sure the temperature inside the
chamber has reached the set temperature, and then put the items in batches. Add no more
than 1/3 of the container volume each time, in case the temperature rises too much.

• The temperature display value shows the temperature of temperature sensors inside the
device. Although the displayed temperature may sometimes differ from the actual
temperature in the center of the device, it will get close to the real temperature gradually.

• A through-hole is installed on the side or back of the device to allow test lines to exit the test
box. After drawing out the test lines, be sure to re-plug the test hole with insulating material,
otherwise the temperature inside the box will not be completely lowered, resulting in
condensation around the outside of the hole.

• Clean the device with diluted neutral detergent. Do not use brushes, acid, gasoline, soap,
polish or hot water to clean the frozen storage container, as these materials may damage
the surfaces and plastic and rubber components.

• After a period of operation, mostly if the frequency of door openings is high, a layer of frost
may form on the inner wall and the inner door. If the frost layer is too thick, it will affect the
insulation effect of the device and increase the power consumption. Therefore, after a
period of time, when the frost layer reaches about 5mm, it should be defrosted with the
defrost shovel included.

• Please remove the frozen items in the device and put them in a suitable storage place
before defrost, so as to avoid the damage of goods for temperature rise.

• There are many cooling coils on the back and side of the inner wall. Don't use sharp objects
such as knives, ice chisel, or screwdrivers to remove the frost on the inner wall. Be careful
not to scratch the inner wall when defrosting, otherwise it will cause a failure of the device.

• Cut off the power when the refrigerated storage box will not be used for a long time.

PROBLEMS

CAUSES AND SOLUTIONS

Equipment does not work

Is the power outlet charged?

Is the power plug plugged in or lose?

Is the power fuse disconnected?

Is the supply voltage too low or too high?

Compressor is not running
Is the temperature set correctly?

Is the temperature inside the cabinet too low?

The temperature does not reach the set
value
Are the doors not tightly closed or open too many times?

Are there too many items put in at one time?

Is the ambient temperature too high?

High noise

Is the cabinet placed on a flat ground? Does the cabinet contact the
wall?

Condensation on cabinet surface

In rainy and humid seasons, door condensation is normal, and it shall
be wiped off with a dry cloth.

The door is not closed properly, and the
cool air leaks

Is the temperature set correctly?

Is the temperature inside the cabinet too low?

Follows are not failure

• There will be a slight crash sound of the compressor switch when the compressor is starting and
stopping. The cooling time is longer than normal for the first use of the device. These are normal
phenomenon.

• In humid ambient, there can be a little frost forming on the surface of the device, use the dry cloth to
wipe it off will be OK.

• The twice opening of the door should after 5 minutes, otherwise the outside warm air will come in, the
negative pressure inside the device caused by a decline will make the door difficult to open.

• A sound of liquid flow inside the device is a normal sound of refrigerant circulating.
