General Installation
The installation must be carried out in accordance with these instructions, and must be
conducted by designated, qualied and competent personnel.
The Digital Mixing 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 planning your installation, make sure that the Controller is installed within the cable
length range supplied (Cable length 9.5 metres).
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.
Full bore isolating valves must be installed to both inlets (supplied) and it is recommended
to t isolators on the outlet, close to the Digital Mixing Valve for ease of maintenance.
Caution! Risk of product and property damage. The Digital Mixing Valve must be
installed in a dry, ventilated area where it will not freeze.
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-o󰀨s will not e󰀨ect 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 Mixing Valve.
Suitable Plumbing Installations
Dual Digital Mixing Valve (High Pressure)
1. Gas Heated System - The Digital HP shower can be installed with a combination boiler.
2. Unvented Mains Pressure System - The Digital HP shower can be installed with an
unvented, stored hot water system.
3. Mains Pressurised Instantaneous Hot Water System - The Digital HP shower can be
installed with systems of this type with balanced pressures.
4. Gravity Fed Showers
Caution! Risk of product damage. Do not t the Mira Digital Mixing - High Pressure/

Use of Flow Regulators with Combination Boilers
The Digital Mixing 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 Hot inlet ow regulator may need to be used to ensure that the Digital Mixing Valve can
deliver a full range of water temperatures.
Note: The Mira Dual outlet Digital Mixing Valves do not have a factory t ted hot inlet ow
regulator. These are supplied in the component pack. The table indicates which ow
regulator should be tted in the hot water inlet of the Digital Mixing Valve if installing
to a combination boiler system.

Important Installation Considerations
• Ensure Pumped for Gravity showers are not connected to any mains water pressure
e.g. stored gravity hot water and cold mains water.
• High Pressure/Combi Valves should not be tted to a Pumped Gravity System.
• The Digital Mixing Valve should not be installed where it can become frozen or be subjected
to ambient temperatures in excess of 40ºC.
• Position the Digital Mixing Valve so that there is enough room for maintenance (e.g.
removal of the valve lid) and make sure safe and easy access is available at all times.
• Installing the Digital Mixing Valve onto shared water supplies may reduce its flow
performance.
• Avoid installations where air locking could occur.
• Cold water cisterns should hold no less than 230 litres and Hot water cylinders no less
than 210 litres. (Gravity system only).
• Your water supply system must be capable of delivering up to 16 l/min mixed water.
• Ensure water supply temperatures are within specication. Hot water 55˚C to 65˚C, Cold
water 1˚C to 20˚C.
• To reduce any e󰀨ects of water hammer secure all pipe work rigidly.
• Do not t the valve in a position where Bluetooth® communication with the Digital Mixer Valve
is poor e.g. mixer valve installed under metal bath, in front of metal cistern, on foil backed
plasterboard.
• Water supply pipes must be ushed prior to connecting the mixing valve to the system
so debris cannot enter the mixing valve internals.
• Fully commission the product after installation taking care to look for any leaks and
correct operation.
General Installation Requirements
The installation must be carried out in accordance with these instructions, and must be
conducted by designated, qualied and competent personnel.
A separate, permanently connected supply must be taken from the ring main to the appliance
through a 3 AMP double pole switched fused 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 0.5mm.
Pipework must be rigidly supported to avoid any strain on the connections.
Long outlet pipework (dead-legs) should be kept to a minimum to avoid temperature uctuations.
Supply pipework layout must be arranged to minimize the e󰀨ect of other outlet usage upon
the dynamic pressures at the Digital Mixing Valve inlets.
To eliminate pipe debris it is essential that supply pipes are thoroughly ushed through before
connection to the Digital Mixing Valve.
Cables routed through wall cavities, chased into solid walls, directed under baths or in
attic spaces must be tted in such a way that they can later be removed. To facilitate this
appropriate cable conduit/trunking must be used at all times. The conduit/trunking must be
at least 20mm diameter/square to allow for the safe removal of the connectors.
Failure to do so may result in an inability to carry out any maintenance or service. Safe and
easy access to the product should be available at all times.

2120
Valve Installation Orientation
The Digital Mixing Valve (which contains the thermostatic mixing valve)may only be orientated
in the positions shown below. Failure to do so will compromise the ability of the unit to fail-safe
and deliver constant blend. If the power supply cable is damaged, it must be replaced by
the manufacturer or a service engineer.
Warning! Turn o󰀨 the electrical and water supplies before proceeding with the installation
of the appliance. The electricity must be turned o󰀨 at the mains and the appropriate
circuit fuse electrically isolated, if applicable. Caution! Risk of product damage. Do
not run Pumped Valve (low pressure version) without a water supply.
1. Isolate the electrical supply to Digital Mixing Valve.
2. Mark the xing holes in the required positions. Drill and plug the xing holes.
