For performance information in a vacuum or with hot side temperatures other than 27°C or 50°C, consult one of our Applications
Engineers.
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.
