The Data Cable must be placed through the Suppression Ferrite and then looped around the

Installation Schematic
1.
Inlet and outlet isolating valves must be installed close to the DMV for ease of
maintenance.
2.
The use of supply-line or zone strainers will reduce the need to remove debris at
each mixing valve point. The recommended maximum mesh aperture dimension
for such strainers is 0.5 mm.
3.
Inlet pressure tappings which allow measurement of the inlet pressures to
the mixing valve under operating conditions are particularly recommended for
healthcare applications.
4.
Pipework must be rigidly supported and avoid any strain on the connections.
5.
Pipework dead-legs should be kept to a minimum.
6.
Supply pipework layout should be arranged to minimise the effect of other outlet
usage upon the dynamic pressures at the mixing valve inlets.
7.
Inlet and outlet threaded joint connections should be made with PTFE tape or
liquid sealant. Do not use oil-based, non-setting joint compounds.
8.
To eliminate pipe debris it is essential that supply pipes are thoroughly flushed
through before connection to the spout and to the Rada Sense DMV.
9.
The DMV may
only
be orientated in the positions shown when mounted on a rigid
vertical surface and on top of a rigid horizontal surface in any orientation.
