COMMISSIONING
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 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:
1.
Make sure that hot and cold water is available at the valve inlets, and the outlet
is open.
2.
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.
Note!
For Type 3 valves in healthcare installations the maximum blend temperature
is determined by the application, refer to the TMV3 Requirements Manual.
The Rada Thermotap-3 is fully performance tested, and the maximum temperature
is preset to approximately 41°C under ideal installation conditions at the factory.
Site conditions and personal preference may dictate that the maximum temperature
has to be reset following installation.
This product includes an
adjustable stop ring
which limits the rotation of the lever
control. The stop ring and lever will need to be assembled correctly to make sure
that the flow shuts off and the maximum temperature limit is set.
If the tap has been dismantled for servicing of the internal parts, or the lever
removed for any reason, refer to sections:
'Flow Shut Off Setting'
and
'Maximum
Temperature Setting'
.
