We mentioned that do not power the TEC modules for a long time when there is no heat sink. 

Here is the right installation method:

A. Install a heat sink in one side of TEC module, while the other side installs a thermal load. The installation surface flatness is less than 0.03mm. Remove any burrs or pollutant.

B. Make sure a good contact between TEC module and Thermal load, as well as TEC module and heat sink. Thermal conductive pad needs to be put in the contact surface.

C. Fix the TEC module with proper stress so as not to damage the TEC.

Operation conditions:

1. The voltage of DC power supply doesn't exceed default voltage of the TEC modules. The ripple coefficient is less than 10%.

2. The current cannot exceed default current.

3. When the TEC is working, do not reverse the voltage instantaneously. Reverse the voltage after    5 mins.

4. The ambient humidity cannot exceed 80%.
