Do not change frequently of the using values, to avoid compressor frequently 9

open and overload , affect the service life of the equipment. the machine have the power switch, in case of failure operation, please cut off power supply, to check whether the control circuit is in good condition, then check the other parts.(see diagram) Be sure to close the inner door,before close the outdoor. If the inner door didnâ&#x20AC;&#x2122;t close well, even if close the outdoor, the device may not be able to maximum work performance, please be careful when close the door.

Recommend to use the pure water or distilled water to fill in the tank , ensure the water is clean.

In order to maintain the appearance of the equipment, do not use corrosive solution to clean the machine, use dry cloth or alcohol to wipe to keep chamber clean. pls keep chamber dry and cut off power supply when the equipment is not using.

In order to ensure the cabinet uniformity inside , should often check whether the axial flow fan is running normally .When doing the experiment, should not put too many articles to stop the fan outlet, make sure the air circulation in the chamber is in good condition. Do not touch the thermal probe in the collision to cause temperature abuse.

Make sure shelf is fixed well, otherwise may make articles damage Don not lean on the glass or press to the glass, it may cause harm to personnel do not lean on door to avoid the equipment overturned or door broken,making people harm or machine broken.

When equipment fails to work, please ask professional technician or the factory sales department for help. Please donâ&#x20AC;&#x2122;t do anything by yourself.
