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
Consult Marlow Industries’ Thermoelectric Installation Guide or reliability report for more details. For additional
information, please contact one of our application engineers for technical support.
Operation Cautions
For maximum reliability, storage and operation below 85°C is recommended. Excessive power cycling and powering
through thermostatic (on/off) control is not recommended.
