volume of each batch of items to be placed in the ULT freezer 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
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 ULT freezer 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.
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
in the ULT freezer.
After the door is opened, the temperature in the ULT freezer 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 ULT freezer 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
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 ULT freezer shall be taken out with ice
