cleaner and/or cleaning products.
Maximum medium and ambient temperatures: 
-15 to +60°C (5 to 140°F).
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).
Storage and transport temperature: 
-20 to +40°C (-4 to +104°F).
Enclosure to IEC 60529: IP 54, IP 65.

Designed lifetime

This information on the designed lifetime is based on 
using the product in accordance with these operating 
instructions. Once the designed lifetime has been 
reached, safety-relevant products must be replaced.
Designed lifetime (based on date of manufacture) in 
accordance with EN 13611, EN 1854 for pressure 
switches: 10 years.
You can find further explanations in the applicable 
rules and regulations and on the afecor website 
(www.afecor.org). This procedure applies to heating 
systems. For thermoprocessing equipment, observe 
local regulations.
