INSTALLATION
General
The installation must be carried out in accordance with these instructions, and
must be conducted by designated, qualied and competent personnel.
The plumbing installation must comply with the requirements of the U.K water
regulations/Bye-laws (Scotland), or any particular regulations and practices,
specied by the local water company or water undertakers.
The Digital Mixer Valve may be installed in a loft space, under the bath
or in a convenient cupboard space provided there is enough room for
maintenance (e.g. Removal of Digital Mixer Valve lid). Failure to do so may
result in an inability to carry out any maintenance. Safe and easy access to
the product should be available at all times.
When installing a mixer valve in an area not regularly accessed,
consideration for potential leaks must be taken into account. While such
events are unlikely, it is advisable to periodically check the installation
for traces of water on or around the product. If possible, site the valve in
a location where any leak would be contained or routed to avoid areas
sensitive to water damage.
Isolating valves must be installed to both inlets (supplied) and outlet, close to the
Digital Mixer Valve for ease of maintenance.
Caution! Risk of product damage. The Digital Mixer Valve must be installed
in a dry, ventilated area where it will not freeze.
Important Information Regarding Radio Controlled Devices
• Metal objects such as steel baths or sinks, cold water storage tanks, hot
water cylinders, foil lined plaster board walls, radiators and even thick brick
walls, can all dramatically reduce the radio operational range of any radio
controlled product.
• Interference from other radio signals can dramatically reduce the ability of the
Mira Vision User Interface / digital mixer to register or communicate. This may
include; mobile phones, radio control boiler thermostats, wireless broadband
routers, radio control toys, cordless phones, remote outdoor weather stations
etc.
• If you encounter difculty registering the user interface and digital mixer
ensure all other radio interference is temporarily switched off.
• Note! Failure to follow these guidelines can result in poor, intermittent or
complete failure to communicate with the digital mixer.

that excess expansion or pulse pressures do not damage the product or plumbing
system. The expansion vessel may already be tted within the boiler (check
with the manufacturer) and is in addition to the normally larger central heating
expansion vessel.

Use of Flow Regulators with Combination Boilers
The Mira Digital Mixer Valve can demand hot water quicker than some
instantaneous water heaters/combination boilers can provide, especially in winter
when the mains water is colder. A ow regulator may need to be used to ensure
that the Digital Mixer Valve can deliver a full range of water temperatures. The
table indicates the ow regulator to be tted in the hot water inlet of the Mira
Digital Mixer Valve.

Use of Warm-up Feature with Combination Boilers
When using the warm-up feature (see User Guide) with the Digital Mixer Valve
supplied via an instantaneous water heater/combination boiler, the user may
experience a brief temperature uctuation. This is caused by the normal operation
of a standard instantaneous water heater/combination boiler whereby the boiler
will turn off when the ow is stopped (as happens after the warm-up sequence
has been completed). Upon restart of the shower, a cold shot will be ushed
through followed by a brief hot shot until the hot water supply has stabilised.
Unscrew hot inlet plastic nuts and remove pipe and seal to gain access to the
checkvalve cartridge and lter.
Use at blade screwdriver to carefully lever cartridge out.
Fit ow regulator in checkvalve cartridge behind lter as shown.
Ret seal, pipe and plastic nut. Plastic nuts require hand tightening only.

Digital Mixer
Valve (Pumped)
The shower control must be fed from a cold water storage cistern and a hot
water cylinder providing nominally equal pressures. Pipework layouts and
connections must be such that other draw-offs will not effect water supplies to the
shower, shared supplies may lead to airlocking or water starvation. It is therefore
best practice to have independent hot and cold supplies to the Low Pressure
(pumped) Digital Mixer Valve.

Typical Examples of Poor Plumbing and Installation Practices
DO NOT:
• Install the Digital Mixer Valve where it can become frozen
• Position the Digital Mixer Valve where maintenance access is poor
• Install into a system where the cold water cistern holds less than 230 litres
• Install into a system where air locking could occur
• Install the user interface in a position where communication with the Digital
Mixer Valve is poor e.g. mixer valve installed under metal bath, in front of
metal cistern, more than the recommended distance away etc.
• Install the Digital Mixer Valve onto shared water supplies
• Install the Digital Mixer Valve less than 100 mm from the lowest level of water
in the cistern
• Fit plastic pipework unless rigidly supported

Installation Schematic
A separate, permanently connected supply must be taken from the ring main
to the appliance through a 3 amp double pole switched fuse spur providing a
minimum 3mm contact separation gap in each pole.
The use of supply-line or zone strainers will reduce the need to remove
debris at the Digital Mixer Valve. The recommended maximum mesh aperture
dimension for such strainers is 0.5 mm.
Pipework must be rigidly supported to avoid any strain on the connections.
A 30 mA Residual Current Device (RCD) must be included in the electrical
circuit. This may be part of the consumer unit or a separate unit.

17
Mounting on a Vertical Surface
Inlets
Outlet
Inlets
Outlet
Mounting on a Horizontal Surface
Long inlet pipework (dead-legs) should be kept to a minimum to avoid
temperature uctuations.
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
ushed through before connection to the Digital Mixer Valve.
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 offtheelectricalandwater suppliesbeforeproceedingwith
the installation of the appliance. The electricity must be turned off at the
mains and the appropriate circuit fuse electrically isolated, if applicable.

Position and Signal Test
Important! When choosing a position for the Digital Mixer Valve in relation to the
Wireless Controller and the Shower Fittings, consider the following points:
ThelengthofpipeworkrunningfromtheDigitalMixerValvetotheShowerFitting
will have an effect on the showering temperature and the response time when
changing the temperature using the Wireless Controller. The shorter the length
of pipework from the Digital Mixer Valve the better the shower will respond. It
is recommended that this length does not exceed 3 m (Ceiling Fed Fitting) or
4.5 m (Rear Fed Fitting).
The ambient temperature of Digital Mixer Valve site (loft space, airing cupboard
etc...) can have an effect on showering temperature. Insulate all pipework as
required, particularly from the Digital Mixer Valve to the Shower Fitting.
Important! Insulate pipework only. Do not attempt to insulate or cover the
Digital Mixer Valve.
The Wireless Controller can be sited up to 10 m from the Digital Mixer Valve.
However, wall thicknesses and construction types may affect the remote signal
strength and thereby reduce the range. The Controller range should be tested
on site prior to installation to ensure shower’s reliability.
Refer to Section -INSTALLATION “Important Information Regarding Radio
Controlled Devices”.

19
Switch on the electrical supply to the Digital Mixer Valve.
The Wireless Controller will make 6 short beeps and the clock will change to
’10:00’ as it registers itself to the Digital Mixer Valve. During this 30 second
process, a water droplet symbol will also appear on the screen.
Note! DO NOT remove the batteries or switch off the Digital Mixer Valve until
the droplet symbol disappears – this will indicate that the Digital Mixer Valve
and the Wireless Controller have been assigned to each other.
Place the Digital Mixer Valve in the required location, no more than 10 m from
the nal position of the Wireless Controller.
Connect the Digital Mixer Valve to the electrical supply via a 3 amp fused
spur switch. Do not switch Digital Mixer on!
Bring Wireless Controller to within approximately 1 m of the
Digital Mixer Valve. Fit 3 x AA batteries supplied.
The following procedure details how to assign the Wireless Controller to the Digital
Mixer Valve and test the remote signal strength.
Note! No plumbing connections are required for this test.
Note! Other radio signals from sources such as mobile phones, radio controlled
boiler thermostats, wireless broadband etc. can dramatically reduce the ability of
the Digital Mixer Valve to register.
It is recommended that such items are switched off during this process.
The wireless controller display will indicate the software version for 5 seconds
before displaying the clock default time of ‘4:00’.

20
Place Wireless Controller in approximate nal position (no
more than 10 m from Digital Mixer Valve) and test wireless
signal by pressing the “ ” and adjusting the temperature. If
temperature display remains unchanged and “out of range”
symbol is displayed, units are unable to communicate with each
other.
If test fails, reposition unit(s) and
repeat test until satised shower will
work reliably.
Caution! Risk of product damage.
Do not run Pumped Valve (low
pressure version) without a water
supply for longer than 15 minutes
during test.
Isolate electrical supply to Digital
Mixer Valve.
