polish or hot water to clean the frozen storage container, as these materials may damage
the painted surfaces and plastic rubber components.
uAfter a period of operation, a layer of frost will form on the inner wall and the inner door. If
the frost layer is too thick, it will affect the insulation effect of the freezer 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 attached.
uPlease remove the frozen items in the freezer and put them in a suitable storage
environment before defrost, so as to avoid the damage of goods for temperature rise.
uThere 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 freezer .

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.
