V. 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 supply and replace the one
with the same model and specification.
Fans are installed in the operation room. Don't put fingers or any objects into the
cover. Please cut off the power supply before maintenance.
Please turn off the power switch when stop using.
