INSTALLATION
General Information
The product 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 the product 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 the product 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 product in a location where any leak would be contained
or routed to avoid areas sensitive to water damage.
Inlet isolating valves (supplied) must be installed.
We strongly recommend that full bore outlet isolation valves are tted as close to
the product as possible for ease of service and maintenance.
The water supplies to this product must be isolated if the product is not to be used
for a long period of time. If the product or pipework is at risk of freezing during this
period they should also be drained of water.
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
Platinum Wireless Controller / 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,
wireless doorbells etc.
• If you encounter diculty registering the wireless controller and digital mixer
ensure all other radio interference is temporarily switched o.
Note! Failure to follow these guidelines can result in poor, intermittent or complete
failure to communicate with the digital mixer.
Note! Both the Wireless Controller and Digital Mixer contain internal radio
transmission aerials which are directional in operation. In order to achieve optimum
radio signal strength and therefore optimum communication distance It may be
necessary to alter the Wireless Controller and Digital Mixer relative orientation /
position to each other.

Only install the High Pressure Digital Mixer Valve with a multipoint gas water heater
or combination boiler of a fully modulating design (i.e. where the water draw-o
rate indirectly controls the gas ow rate to the burner).
An expansion vessel must be tted (and regularly maintained) if any form of backow
prevention device is tted, e.g. non-return valve or PRV. This will ensure 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 Hot inlet ow regulator may need to be used to ensure that the
Digital Mixer Valve can deliver a full range of water temperatures.
Note:
The Mira Single outlet digital mixing valves are factory tted with an 8 l/min hot
inlet ow regulator. If installing a single outlet digital mixer with a combi boiler rated
36kW or greater or to mains pressurised systems the hot inlet ow regulator should
be removed.
Note:
The Mira Dual outlet digital mixing valves do not have a factory tted 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 Mira Digital Mixer Valve if
installing to a combination boiler system.

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/remove the ow regulator from checkvalve cartridge behind lter as required.
Ret seal, pipe and plastic nut. Plastic nuts require hand tightening only.

Outlet 2 (warm)
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 o 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.

Packages of this type, tted with a tempering valve can be used. A drop type pressure

should also be tted. This will ensure that excess expansion or pulse pressures do
not damage the product or the plumbing system. The expansion vessel may already
be tted externally or internally within the thermal store (check with thermal store

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-os will not eect 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.

1199702-W2-H
Typical Examples of Poor Plumbing and Installation Practices
DO NOT:
• Install the Digital Mixer Valve where it can become frozen
• Install the Digital Mixer Valve where it can be subjected to ambient tempera-
tures in excess of 40ºC.
• Position the Digital Mixer Valve where maintenance access is poor or unsafe
• 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 wireless controller 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, on foil backed plasterboard, 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 (low pressure version only)
• Fit plastic pipework unless rigidly supported
• Install a High Pressure/Combi Valve to a Pumped Gravity System
