Maintenance
We recommend a function check once a year, or
every six months if operated with biologically pro-
duced methane.

Designed lifetime
The Pressure Equipment Directive (PED) and the
Energy Performance of Buildings Directive (EPBD)
demand regular checks on and maintenance of heat-
ing systems in order to ensure a high level of use
in the long term, a clean method of operation and
safe function.
The service life on which the construction is based,
hereinafter referred to simply as the “designed
lifetime”, is compiled from the relevant standards.
You can find further explanations in the applicable
rules and regulations and on the afecor website
(www.afecor.org).
This information on the designed lifetime is based on
using the product in accordance with these operat-
ing instructions.
The product must be serviced at regular intervals.
Once the specified designed lifetime has been
reached, the safety-related functions must be
checked in accordance with the section entitled
“Maintenance”.
If the product passes the aforementioned function
tests, you can continue to use it until the next sched-
uled maintenance operation. At this point, these tests
must be repeated.
If the product fails one of the aforementioned tests,
it must be replaced immediately.
This procedure applies to heating systems. For ther-
moprocessing equipment, observe national regula-
tions.
Designed lifetime (based on date of manufacture)
in accordance with EN 1854 for pressure switches:
Medium Designed lifetime
Switching cycles Time [years]
Gas 50,000 10
Air 250,000 10
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).
