Mira Platinum Dual Installation Manual page 20

Long inlet pipework (dead-legs) should be kept to a minimum to avoid temperature
fluctuations.
Supply pipework layout must be arranged to minimize the effect of other outlet
usage upon the dynamic pressures at the Digital Mixer Valve inlets.
To eliminate pipe debris it is essential that supply pipes are thoroughly flushed
through before connection to the Digital Mixer Valve.

Mounting on a Vertical Surface Mounting on a Horizontal Surface
The Digital Mixer Valve (which contains the thermostatic mixing valve) may
only be orientated in the positions shown above when mounted on a vertical
or horizontal surface. Failure to do so will compromise the ability of the unit to
fail-safe and deliver constant blend.
If the supply cords are damaged, they must be replaced by the manufacturer
or a service engineer.
Warning! Turn off the electrical and water supplies before proceeding with
the installation of the appliance. The electricity must be turned off at the
mains and the appropriate circuit fuse electrically isolated, if applicable.
