Installation and Operating Instruction
MH 6114 INT PolluTherm, Page 6
To remove the red snap-in hook, use a flat-head
screwdriver to raise and remove the housing
(refer to Figure 7).

C-rails installed
6. Connection of the Sub-Assemblies
To open the housing, press on the two locking
lugs at both lower corners of the housing cover
and lift up the cover.

6.1 Connecting the Flow Sensor
Remove the appropriate moulded rubber part from
the housing (Figure 8) and cut a hole in the
moulded rubber part. Next, lead the cable through
the hole and establish strain relief using a cable-
tie (Figure 9).
The pulse line (white) is connected to the terminal
10 (+) and the line GND (blue) connected to the
terminal 11 (-). The terminal 9 is provided for the
voltage supply (brown). The yellow connection
cable should not be connected. This is only used
for test purposes. (Figure and Table 10).
If the flow sensor is an AN130/SAN130/FAN130,
the white wire is connected to terminal 10 (+) and
the brown wire to terminal 11 (-).
If the flow sensor is an HRI-Mei FS, the white wire
is connected to terminal 10 (+) and the grey wire
to terminal 11 (-).
The above mentioned cables must not be
connected other than stated, as the
electronics of the flow sensor could get
damaged!
