D.H.W. fLoW SWITCH, fILTER AND fLoW LIMITER

14.6 flow limiter

The M110B.24SM/... model is factory fitted with a 10 litre/min.
flow limiter.
If on the M110B.32SM/... model the flow 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 available:

Nominal flow rate (litres/min)

Colour

10

Blue

12

Red

14

Pink

To install the flow limiter:
1 Remove the flow switch group as explained in the section

"Removal of the flow switch group and d.h.w. circuit filter"
page 31.

2 Separate the flow switch plug 1 from the body 4 (Figure 14.4)

levering with a screwdriver one of the two hooks.
