The maintenance of low temperature refrigerator is particularly important for using normally and prolonging its life and. Today Guanya will talk something about the details of daily maintenance.

Step 1: Clean the storage box
The storage box should be cleaned once a month,  wipe out the dust on the enclosure and the interior and all the attached parts by a dry cloth. If the box is dirty, use a clean cloth soaked with neutral detergent to remove the stolen goods and wipe away the remaining detergent with a wet cloth, and then wipe it with a dry cloth.

Step 2: Clean the condenser filter net
When the alarm light of the ''dirty condenser'' is scintillating on the display panel of the storage box, it is necessary to clean the filter net. Clean the filter once a month even if the light is not on. If the filter is blocked, the compressor life will be shortened and the cooling is slower.

Step 3: Defrosting the inner wall
The frosting is usually on the upper part of the box and the inner door. The frost may cause a gap between the box and the door seal, resulting in a bad cooling. Defrost the inner door with the complimentary defrosting shovel of the equipment.

The battery of power off the alarm is also consumable. The battery life is about 3 years, if the battery is used more than 3 years, it may not function when the alarm is called, so that the storage settings may be affected.
