Installation Recommended mounting methods: Bonding with thermal epoxy, mounting in compression with either thermal grease or flexible graphite products. For additional information, please refer to our TEC Installation Guide. Operation Cautions For maximum reliability, storage and operation below 85°C in a non-condensing environment is recommended. To minimize thermal stress, use linear/proportional temperature control or a similar method rather than an ON/OFF method.
