14.6 Flow limiter
The M96.24SM/... model is factory fitted with a 10 litre/

rate of the d.h.w. circuit is too high, it is possible to limit
it by installing a flow limiter. The following sizes are avail-
able:
Nominal flow rate (litres/min) Colour
10 Yellow
12 Brown
14 Pink
To install the threaded ring with the flow limiter:

Remove the flow switch group as explained in the
section 14.5.
2 Remove the filter from the flow switch group.
3 Unscrew the threaded ring 7 (Fig. 61) and re-
move it from the body 2.
