• 1. Be sure to check the positive and negative terminals. If you are not sure, check them on the specification drawings available on our membership website (free registration required). If you cannot find the specification drawings on the website, please contact us.
• 2. The recommended maximum operating temperature of our thermo-electric modules is 135℃ or below (instantaneous temperature limit is 200℃). If a thermo-electric module is used under temperature conditions exceeding the recommended maximum operating temperature, the devices inside the thermo-electric module may deteriorate earlier.
• 3. There is a maximum value of cooling efficiency of a thermo-electric module with respect to the current (voltage) value. However, the value does not correspond to Imax (maximum current) or Vmax (maximum voltage) in the catalog. If you are not sure, check them on the specification drawings and characteristic diagrams available on our membership website (free registration required). If you cannot find the specification drawings or characteristic diagrams on the website, please contact us. Exceeding the maximum current or voltage shall void the warranty.
• 4. Any water or conductive liquid entering inside the thermo-electric module may cause a short circuit, performance degradation, or damage of the thermo-electric module. When using the product in an environment where it may easily be exposed to moisture, we recommend that you use a seal type product.
• 5. Multistage thermo-electric modules cannot be used for polarity inversion applications. Make sure to use them only for cooling applications.
• 6. Thermal strain of any unit such as the heat sink may add pressure on the module due to unbalanced load, which may damage the module. Please ensure proper design and installation.
• 7. Thermo-electric modules are relatively resistant to compressive stress (when evenly loaded) but have a low tolerance for tensile stress. Therefore, avoid any design in which a thermo-electric module serves as a mechanical structural member.

• 1. Do not bend or pull an end of the lead wire forcefully. Do not lift the module by holding the lead wire. Doing so may break the lead wire.
• 2. Do not apply power to the thermo-electric module without installing any heat exchanger such as a heat sink. Doing so raises the temperature of the thermo-electric module, which may cause burns or damage of the thermo-electric module.
• 3. Before installing the thermo-electric module, clean the surfaces of the cooling plate and heat sink that will come into contact with the thermo-electric module. If any contact surface is stained, the thermo-electric module may not show its maximum performance due to low heat conductivity or defective bonding.
• 4. When applying heat conductive grease to the contact surface between the thermo-electric module and the cooling plate or heat sink, make sure that the layer of heat conductive grease is not contaminated with air. Any air in the grease layer inhibits heat conduction, preventing the thermo-electric module from showing its maximum performance.
• 5. Use a milling machine to flatten the surfaces of the cooling plate and heat sink that will come into contact with the thermo-electric module. Any contact surface that is not flat enough inhibits heat conduction, preventing the thermo-electric module from showing its maximum performance. It may also cause damage of the thermo-electric module.
• 6. When you need to remove the thermo-electric module after installing it, apply a force to gradually slide it sideways instead of trying to pull it out vertically. Note that using a pointed tool may damage the interior of the thermo-electric module. If the heat conductive grease is hardened, heat it to reduce its viscosity for easy removal.
• 7. The recommended storage conditions are temperature 0 to 30℃ and humidity 60%RH or less.
• 8. Multistage thermo-electric modules cannot be used for polarity inversion applications. Make sure to use them only for cooling applications.

The warranty period of the thermo-electric module is one year after the shipment from Ferrotec. Ferrotec shall be responsible for any failure occurring during the warranty period resulting from manufacturing and replace the faulty units. However, Ferrotec shall not be responsible for repair and other costs related to the thermo-electric module. Ferrotec shall not be responsible for any damage to any equipment other than the thermo-electric module due to moisture from condensation on the thermo-electric module. The warranty shall not cover the failures listed below even during the warranty period.

• 1. Failure caused by improper handling by the customer
• 2. Failure caused by modification or repair performed by a party other than Ferrotec
• 3. Failure caused by anything other than the thermo-electric module
• 4. Failure caused by use of the product under conditions exceeding the specifications
• 5. Failure caused by a natural disaster such as fire or earthquake, or other disaster such as war.
