4.
Once the desired maximum blend temperature is achieved, refit the hub without
disturbing the spindle, positioning it so that the lug is against the stop on cartridge
face, preventing further rotation towards hot. Check that blend temperature has
not altered.
5.
Refit the temperature knob so that the lever is aligned with the maximum hot
position shown on the body shroud.
6.
Refit the locking screw.
Commissioning Checks
(Temperatures should always be recorded using a thermometer with proven accuracy)
1.
Check inlet pipework temperatures for correct function of checkvalves.
2.
Operate the flow control and check:
- Flow-rate is sufficient for purpose.
- Temperatures obtainable are acceptable.
- All connections and control body are watertight.
- Check that the supply pressures are within the range of operating pressures
for the valve.
- If the outlet temperature is set correctly then refer to
Commissioning Checks
.
- If adjustment of the temperature is required, carry out the procedure shown
below;
1.
Remove the temperature knob, using the 3 mm A/F hexagonal wrench (supplied).
2.
Pull off the temperature hub.
3.
Rotate the spindle until the required maximum blend temperature is obtained
at the discharge point (clockwise = decrease temperature).
When resistance is felt do not use force to turn any further, as this can
damage the internal parts.
For Type 3 valves in healthcare installations the maximum blend temperature is
determined by the application - see table under Application and Designation
Temperature and flow knobs are also available with a short lever.
