The designed minimum service life of all these “critical components” is 5 years
providing the Rada 425-t3 c is operated with the recommended operating conditions
and within the recommended operating parameters. However, when supply
conditions and/or usage patterns do not conform to the recommended operating
parameters and/or the recommended operating conditions, the thermostatic unit
and other critical parts may need to be replaced more frequently (‘recommended
operating conditions’ and ‘recommended parameters’ are defined on page 7 of
this Product Manual under the headings of
‘Normal Operating Conditions’
and
‘Operating Parameters’
).
Important!
In healthcare applications such as hospitals, aged person facilities,
residential care homes, etc. and in any other applications where the user is similarly
at risk, irrespective of supply and usage conditions or the evidence of in-service
tests, the critical components should be replaced at intervals of no more than 3
years.
