3. Points needing attention during normal use-disposal of special circumstances
If the equipment has any fault, please check the following faulty points before maintenance:
The equipment can’t be started
●
Check the power is normally connected or the mains switch is switched on or not?
●
Is the voltage is too low?
●
Is there too much articles stored in the storage box one time?
Bad cooling
●
Is the ambient temperature too high?
●
The inside and the outside door are opened tightly? (Frost between the box body and the door
seal will damage the sealing of door).
●
Is the filter net of the condenser blocked by dirt?
●
Is the temperature setting is correct?
●
Is the storage box far away the direct sunshine?
●
Is the storage box close to heat source?
●
Are the rubber cover and heat insulating material used by the testing through hole placed
correctly?
●
Is there too much unfrozen articles placed in the storage box within several hours? (Under this
case, it is a temporary problem. The setting temperature can be adjusted to high, making the
storage box normally start and shutdown within a short time, so as to reduce the setting
temperature gradually).
●
Is the storage box installed on the solid ground?
●
Does the casing of storage box touch any object?
●
Is the storage box supported with horizontal supports?
●
Is the storage box in low temperature running status?
●
There is noise with the storage box when it is in high temperature due to too much load. This noise
will become smaller and smaller with temperature reduction of the storage room.
●
Please check whether the noise is from the compressor (noise of the ultralow equipment’s
compressor is bigger than the household products).
●
Tapping: It may be caused by the urgent cooling and shrinkage of the parts inside the equipment;
