1.When the unit operates normally, the door frame is slightly warm. The embedded hot gas halo tube
provides free heat to prevent condensation to from on the door frame.
2.Before samples are loaded into a freezer, make sure the unit has reached the set temperature.
Samples should be loaded into the freezer in batches. Each batch should be no more than 1/3 of the
freezer capacity. This process allows the freezer to pulldown the temperature in a reasonable time.
3.The temperature display indicates the temperature where the temperature sensor is mounted
inside the unit chamber, which may vary from the temperature at the center of the freezer, but it will
gradually reach the actual temperature of the freezer over time.
4.Two access ports are available for testing in the back of the freezer. Thermocouple wires can go
through the port holes to reach the interior of the freezer for temperature mapping. The gap of the
holes should be sealed with insulation materials so that the interior temperature is not infl uenced by
the ambient temperature.
5.When cleaning the unit, mild and neutral detergent solution should be used. Never use a hard wire
brush, acid, gasoline, detergent powder, polished powder or hot water for cleaning. These tools and
materials can damage the paint and coating of the unit. Particularly, never use gasoline or a solution
with volatile chemicals to clean plastic or rubber parts.
6.After the freezer runs for some time, a layer of frost usually forms on the interior wall and inner
doors. When the frost gets too thick, the refrigeration eff ect can be impaired. Energy consumption
will increase. If the thickness reaches 5 mm, please use the supplied scrapper to remove the frost.
7.Before removing the frost, temporarily transfer the stored samples to another freezer. This is so that
the temperature does not rise in the unit and damage the samples.
8.Behind the interior walls, there are many refrigeration tubes. Do not use a knife, an ice pick, or a
screwdriver to cut ice and frost. This may damage not only the liner but also the refrigeration tubes.
9.If the freezer is not in use for a long time, please turn off the power and switch off the backup
battery. The power cord should be unplugged.
