Safety Warnings
The function of a Thermostatic Mixing Valve is to deliver water consistently at a pre-designated
temperature.
Rada Thermostatic Mixing Valves are precision engineered to give continued superior and
safe performance provided:
1.
They are installed, commissioned, operated and maintained in accordance with the
recommendations provided and accepted plumbing practices.
2.
Periodic attention is given, as necessary, to maintain the product, the accessory fittings
and the plumbing system in good functional order.
In keeping with every other mechanical product, Rada Mixing Valves should not be considered
as functionally infallible and, as such will never totally replace the vigilance and attention of
maintenance, supervisory and safety staff. Provided that they are installed, commissioned,
operated and maintained, the risk of product failure and its associated consequences, if not
eliminated, are reduced to the minimum achievable.

Important! To ensure continued safe operation of this product, it should be checked and
maintained (see servicing and maintenance section). In addition All ' Critical Components '
must be changed every
5 years
, irrespective of supply and usage conditions or the evidence
of in-service tests. However, when supply conditions or usage patterns do not conform to the
recommended operating parameters the cartridge may need to be replaced more frequently
in line with appropriate risk assessments.
Critical components are Cartridge Assembly pt. no. 1812.007 and inlet service pack 1847.232
or 1847.233 where applicable.
*Note! For optimum performance it is recommended that the maximum hot water temperature
is limited to 65°C.
Caution!
During thermal disinfection the mixing valve can operate up to 85°C for short
periods ensure safety precautions are followed during discharge. Chemical disinfection agents
e.g. chlorine/chloramines combined with higher temperatures will affect the life of the product
adversely and could detrimentally affect the thermostatic performance, to ensure continued
safe operation refer to ‘Safety’ Critical components.
