Precautions for Use
★When the ULT freezer is running, the contact part between the front of the ULT
freezer and the outer door may be heated, which is not a fault. In order to prevent
condensation around the ULTfreezer housing, the heating condensate pipe is
installed.
★Before storing items in the equipment, check that the temperature in the storage
compartment reaches the set temperature and then store the items in batches. The
volume of each batch of items to be placed in the ULTfreezer shall not exceed 1/3
of the volume inside the ULT freezer to prevent excessive temperature rise.
★The displayed equipment temperature is the temperature at the temperature sensor
in the storage compartment. There is a certain difference between the temperature
displayed at the beginning of the operation of the equipment and the actual tem-
perature in the center of the equipment, but as the equipment enters a stable state,
the displayed temperature will gradually approach the actual temperature.
★An inspection hole is installed on the enclosure of the equipment to pull out the
testing line in the ULT freezer during the testing. After the testing line is pulled out,
it is necessary to plug the testing hole again with thermal insulation material, oth-
erwise the temperature in the ULTfreezer may not reach the set temperature and
cause condensation around the outside of the hole (applicable to ULT freezers with
testing holes).
★Please clean the equipment with a diluted neutral detergent.Do not use brushes,
acids, gasoline, soap powder, polishing agents, or hot water for cleaning, otherwise
the painted surface and plastic rubber parts may be damaged. Pay extra attention
to not wipe plastic and rubber parts with volatile solvents such as gasoline.
★When the ULT freezer is not in use for a long period, cut off the power supply and
turn off the battery switch.
★If the ULT freezer is not started again for a long time, a low battery level may occur.
After the battery switch is placed at "ON", the battery can be charged, and the ULT
freezer can run continuously for about one week to charge the battery (applicable
to models with batteries).
★Please minimize the time of opening the door during each access to the items, so
as not to cause great uctuations in the temperature and humidity in the ULT freez-
er.
★After the door is opened, the temperature in the ULTfreezer will rise sharply in a
short time, which is normal, and it will return to set temperature of normal operation
after the door is closed.
★After the ULTfreezer has been running for a period of time, a layer of frost is
formed on the inner wall and inner door of the ULT freezer. If the frost layer is too
thick, it will affect the thermal insulation effect of the ULT freezer and increase the
power consumption. Therefore, after the frost layer reaches 5 mm, the attached
shovel shall be used to defrost.
★Before defrosting, the frozen items in the ULTfreezer shall be taken out with ice
items due to teperature rise in the ULT freezer.
★There are many refrigerating coils behind and on the side of the inner wall. The
frost from the inner wall shall not be removed by sharp tools such as knife, ice
chisel or screwdriver. The inner wall shall not be scratched during defrosting, or the
ULT freezer will fail.
