I. Precautions

When no lighting is needed in the chamber, please turn off the light so as not to affect

the temperature of the upper layer. Turn off the power supply before changing the light

tube.

Handle with care. The angle between the instrument and the ground shall not be less

than 45°.

There is a water outlet pipe behind the equipment. When the inside temperature is

low, a small amount of water will be discharged. Please use a pipe to connect to the

container or sewer.

Do not use acid or alkali and other corrosive articles to wipe the surface. The inside

chamber can be cleaned regularly with dry cloth.

When the set temperature is lower than the room temperature, the over temperature

alarm will be generated if the door opening time is too long, which is not a fault.

When change the fuse tube, please cut off the power sup

ply and replace the one
