Long-term use in the upper ambient temperature
range accelerates the ageing of the elastomer ma-
terials and reduces the service life (please contact
manufacturer).
The set switching point may palpably change in media
and ambient temperatures below -22°F (-30°C).
Transport temperature = ambient temperature.
