VII. Defrosting, Unused and Maintenance
1. Defrost
▶
After working for a period of time in the ultra-low temperature freezer, the inner surface will be frosted, which
will affect the cooling effect and increase the power consumption. When the frost layer is too thick, it should be
defrosted;
▶
Defrost should first unplug the power plug, cut off the power supply, put on special protective gloves, open
the door, and transfer the contents in the device; then use the defrosting shovel to gently remove the surface
frost, which can also let the temperature inside the device rise naturally, melting the frost, then dry the
defrosting water with a dry cloth.
▶
After the defrosting is completed, the power can be turned on and the machine can be cooled.
▶
Put the item back into the device that has reached the temperature.
Note: No electric heaters, metal tools, sharp sharps to defrost.
2. Stop Using
If the ultra-low temperature freezer needs to be stopped for a long time, the power supply (including the battery
power supply) should be cut off, cleaned according to the method of 3 as followed, and the cover is dried to be
sealed.
Before using it again, use a dry cloth to dry the water around the cabinet (especially the part where the door
seal is in direct contact with the cabinet) to avoid freezing the door seal at low temperature.
3. Maintenance
Clean and maintain the ultra-low temperature freezer at regular intervals.(For safety reasons, the power plug
must be unplugged before scrubbing)
Wipe the inner and outer surfaces of the ultra-low temperature freezer with a warm, damp cloth.
When there is serious stain, wipe it with a neutral detergent for washing utensils, and then wipe the water stain
with a soft cloth.
Note: Do not directly sprinkle water on the cabinet to avoid the insulation of the electrical
components and the metal parts being rust. Never use hot water and corrosive detergents or
organic solvents to clean the cabinet.

other safety hazards!
