4.3 Cautions before use：
ØRemove all package components (include the protection foam inside the package)
Caution: Do not put the packing plastic bag within reach of children as suffocation may result。
ØCheck the device, accessories and document with the device as per list of packing
ØClean：make a clean of the device before use it.
ØDo not turn on the freezer at once when the freezer is well located, must wait 24 hours for the
first start.
4.5 Standing
Operate as follows for the first start：
1. Connect the power cord to the appropriate socket during no-loading.
2. Turning on the power-lock at the right-side of the bottom. (If a back-up cooling system is
installed with, turn off its power at first ).
3. Set the desired temperature point between -10°C to -86°C, for the best performance of the
machine, when the user need to set the temperature below -80°C, should set the temperature
at -80°C at first, once the temperature of the freezer come down to -80°C, keep it work stable
at -80°C, after 3.5 hours, set the temperature below -80°C as desired. Factory setting at -80℃.
4. The high temperature alarm will be activated when the power is on. That's a normal
phenomenon. Once the temperature come down to the set point, the alarm will be closed. The
alarm buzzer voice could be eliminated by touch the MUTE button.
5. Articles could be stored inside the freezer after a 24-hour normal running. (Make batch
treatment to store articles, each time do not over a third, after 12 hours of normal running, then
store another a third .)
6. Do not open the door during the cooling process, will cause the temperature rise.
7. For back up cooling system, if installed, do not open it when the freezer is working properly.
When the freezer is failure, could turn on the system to keep the inside temperature at a proper
value.
4.6 First initial starting
ØThere must be an authorized person responsible for the freezer in customer's office, to
check the operation status and make daily record. The inside temperature of cabinet will rise
up during the failure problem, if it is not available to be repaired in a short time, take out the
stored items and transfer to other safe locations.
ØPrior to put the articles inside the freezer, should check if the temperature set range of this
device is matching the requirement of the articles.
ØDue to the Inertia of refrigeration, there is a little difference between the actual temperature
displayed on the controller and the set temperature. This is a normal phenomenon.
ØMeiling's ultra low temperature freezers are storage devices, do not put excess "hot"
samples into the freezers at one time, or will cause compressor damage after long time
working without stop. Attention to put in samples and set temperatures in batches.
ØDo not put electric devices in the freezers without permission.
ØDo not change the setting temperature frequently within a short time, or the current
temperature may not reach the setting temperature as the inertance; Do not cover sensors
in the freezer when you put in samples and keep some distances between the samples and
the inner side of the freezer to make sure the cold air will circulate successfully in the
freezer, or will cause the instability of the inner temperature and inaccuracy of the display
temperature.
CAUTION.
ØPlease use the wrench to rotate the supporting feet clockwise to extend them, so that it rests
on the ground. Make sure the freezer does not move when using.

After the alarm sound is artificially eliminated in the fault state, the fault delay alarm will not start if a
new fault occurs, that is, the digital tube will flash to display the fault code, and the buzzer will no
longer alarm; The fault delay alarm will not be effective until all faults have been eliminated, and the
buzzer can re-alarm.
Do not immediately put any items in the medical freezer when just connect to the power. Let the
refrigerator run for a period (about 24 hours), and then put the items in the refrigerator.
When put in items to the refrigerator, if the item is too moist or too dry, it will affect the change of
humidity in the box. The item is best sealed and stored. Similarly, the humidity of the working environment of
the medical freezer will also affect the humidity change in the box, especially the excessive opening of the
door or the door is not closed.
Each time for storing items, they cannot exceed 1/3 of the cabinet capacity, after reach the
actual temperature and run normally for 24 hours, then put another 1/3 of the cabinet capacity items.
Please be careful not to block the air outlet and the air inlet when put in the items.
Do not place the item directly on the bottom of the medical freezer. It should be placed on the bottom
rack; otherwise it will affect the cooling effect of the medical freezer.
Do not open the door during the cooling process; otherwise it will cause the temperature to rise.
Due to the cooling inertia, the display temperature and the set temperature may be different when the
product reaches the set value and shutdown. This is a normal phenomenon.
Warning: Please keep the medical freezer out of reach of children.
7.Defrost, Unused and Maintenance
Warning:
In order to prevent personnel electric shock or injury, please cut off the power supply of the storage
box before any repair and maintenance to ensure that no drugs or suspended particles around the
device will be inhaled during the maintenance, otherwise it will endanger your health
7.1 Defrost, Unused and Maintenance
After working for a period of time, the inner surface of the product will be frosted, which will affect the
cooling effect and increase the power consumption. It is recommended that the frost layer should be
defrosted when it is too thick.
Turn off the power, open the door, and transfer the items to a cool place;
Use a defrosting shovel to gently remove the surface area cream (also let the temperature inside the
cabinet rise naturally, melting the frost);
In order to speed up the defrosting process, a flat-bottomed container filled with hot water of less than 50 °
C can be placed in a storage cabinet. Then use a dry cloth to clean the remaining ice water from other
places. Reload the item into the storage cabinet;
Turn on the power and turn it on.
