1. Setting the preset temperature in the non-adjustable form.
• Remove the cap and the cam.
• Refit the cap and, at approx. 50% flow rate, adjust the
temperature to 40°C.
• Remove the cap and refit the cam so that the index mark on the
body is between the two lugs on the cam.
• Refit the cap with the index mark on the body between the Max
and Min markings on the cap and check the temperature at the
maximum and minimum flow rates. There should be no more
than a 3°C difference from the nominal temperature setting.
• The cap should be locked in position.
2. Setting the maximum temperature in the adjustable form with
a maximum preset temperature.
• Remove the cap and the cam.
• Refit the cap and, at approx. 50% flow rate, adjust the
temperature to the required maximum temperature.
• Refit the cap with the figures on the cap indicating the maximum
temperature aligned with the index mark on the body.
• Mark on the body of the valve (use a felt tip or similar temporary
marker) the point between the Max and Min marks.
• Remove the cap and fit the cam so that the outer edge of the
clockwise lug line up with the temporary mark.
• Refit the cap with the maximum temperature figure aligned with
the index mark. The cap should not be able to rotate
anti-clockwise.
• Check the maximum temperature is correct.
3. Commissioning in an adjustable form with no preset maximum
temperature.
• Remove the cap and the cam.
• Refit the cap and, at approx.. 50% flow rate, adjust the
temperature to 40°C.
• Remove the cap and refit the cam so that the index mark on the
body is between the two lugs on the cam.
• Refit the cap with the 40°C marking lining up with the index
The inlet fittings can be stripped down
and cleaned except for the non-return
valve that, if removed, needs to be
replaced by a new cartridge.
In-service tests and any necessary maintenance should be carried out
on a regular basis, at least once a year. A record of the results should be
retained for future checks.
