Important installation notes

If the distance between the pumps and the module is less
than 50 cm, the add-on module's counting performance might
be affected.
Chromed trims interfere with optimum radio reception. We
recommend replacing chromed rosettes with "radio rosettes".
With this particular rosette type, shielding of radio signals is
only minimal.
Only mount the radio add-on module on radio-enabled water
meters with round recesses (1), above the scanning disc
(inductive scanning)!
The module must not be mounted on water meters with
square (2) recesses!
Device parameterisation must be completed prior to mounting!
A minimum distance of 5 cm between the radio add-on mod-
ule and other electrical devices shall be observed!
The radio add-on module must be protected against excessive
moisture and heat. Ingress of moisture and excessive heat
may damage the device.
Do not use solvents on the radio add-on module.
For installation of the radio add-on module we recommend
using a torque screwdriver and a tightening torque of 0,35 Nm.
