Precautions for machine:
1
In order to avoid machine failure of constant temperature and humidity test chamber, please provide power supply within the rated voltage range

2
In order to prevent electric shock or misoperation and failure, please do not turn on the power supply before the installation and wiring are completed

3
This product is non explosion-proof
Please do not use the constant temperature and humidity machine in the bad environment with combustible or explosive gas

4
Please try not to open the door of the test chamber during the operation of the instrument
Opening it at high temperature may cause scald to the operator, and opening it at low temperature may cause frostbite to the staff in the morning, and may cause icing of the evaporator and affect the refrigeration effect
If it must be opened, please do some protection work,
5
It is forbidden to disassemble, process, transform or repair the constant temperature and humidity machine without authorization, otherwise there will be danger of abnormal action, electric shock or fire

6
The ventilation hole of the machine body shall be kept unobstructed to avoid failure, abnormal action, reduced service life and fire

7
If the machine is damaged or deformed during unpacking, please do not use it

8
During the installation and setting of the machine, pay attention not to let dust, thread ends, scrap iron or other things enter, otherwise wrong actions or faults will occur

9
The wiring must be correct and grounded
Non grounding may cause electric shock, wrong action accident, abnormal display or large measurement error

10
Regularly check the terminal screws and fixing bracket
Please do not put them in the loose position
