Thermostatic mixing valves only operate correctly when all components have
been serviced and have been tested for correct performance. If any component
is faulty, including the thermostat, the valve will not operate correctly and could
allow full hot water to pass through the valve.
3.
As with all other thermostatic mixing valves, the critical sensing element in the
Rada Exact-3 together with other "critical components" will exhibit wear over a
period of time and usage. All of these parts are contained within the Thermostatic
cartridge.
The designed minimum service life of all cartridges used in Kohler/Mira products
is five years providing the Rada Exact-3 is operated with the recommended
operating conditions and within the recommended operating parameters. However
when supply conditionsand/or usage patterns do not conform to the recommended
conditions and/or parameters the cartridge may need to be changed more
frequently(for definitions of "recommended operating conditions" and
"recommended parameters" see pages 8 and 9).
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 cartridge should be replaced at intervals of no more than
three years.
