Commissioning - Mira Montpellier Installation, Operation, Maintenance Manual

Commissioning must be carried out in accordance with these instructions,
and must be conducted by designated, qualified and competent personnel.
Exercising the Thermostat
Thermostatic mixing valves with wax thermostats are inclined to lose their
responsiveness if not used. Valves which have been in storage, installed but not
commissioned, or simply not used for some time should be exercised before setting
the maximum temperature or carrying out any tests.
A simple way to provide this exercise is:
(a) ensure that the hot and cold water are available at the valve inlets, and the
outlet is open.
(b) move the temperature control rapidly from cold to hot and hot back to cold
several times, pausing at each extreme.
Maximum Temperature
The maximum blend temperature obtainable by the user should be limited, to prevent
accidental selection of a temperature that is too hot.
All Mira Thermostatic mixing valves are fully performance tested and the maximum
temperature is preset to approximately 43
factory.
Site conditions and personal preference may dictate that the maximum temperature
has to be reset following installation. For Type 3 valves in healthcare installations the
maximum blend temperature is determined by the application - see Table under
SPECIFICATION, Application and Designation Information for Type 3 Valves.
