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 fitted 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 Vision 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 difficulty registering the wireless controller 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.

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-off rate indirectly controls the gas flow rate to the burner).
An expansion vessel must be fitted (and regularly maintained) if any form of backflow prevention device is fitted, 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 fitted 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 flow 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 fitted with an 8 l/min hot inlet flow regulator. If installing a single outlet digital mixer with a combi boiler rated 36kW or greater or to mains pressurised systems the hot inlet flow regulator should be removed.

Note: The Mira Dual outlet digital mixing valves do not have a factory fitted hot inlet flow regulator. These are supplied in the component pack. The table indicates which flow regulator should be fitted in the hot water inlet of the Mira Digital Mixer Valve if installing to a combination boiler system.

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 fluctuation. This is caused by the normal operation of a standard instantaneous water heater/combination boiler whereby the boiler will turn off when the flow is stopped (as happens after the warm-up sequence has been completed). Upon restart of the shower, a cold shot will be flushed through followed by a brief hot shot until the hot water supply has stabilised.
2. Mains Pressurised Instantaneous Hot Water Shower, Heated from a Thermal Store
Caution! Risk of product damage. Do not fit the Mira Digital Mixer - PUMPED VALVE with Mains Pressurised Systems.

Digital Mixer Valve (Pumped)

Mira Vision Shower Fittings 90°

30° - 60° cold Air Separation

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.

1184347-W2-G

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

To Mains Power Supply
3 amp switched fused spur.
Easily Accessible

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.

Ensure the switched fused spur is easily accessible for servicable and resetting purposes.

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.

1184347-W2-G

18

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 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 power supply cable is damaged, it 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.

Wireless Controller

Important! When choosing a position for the Digital Mixer Valve in relation to the Wireless Controller and the Shower Fittings, consider the following points:
The Wireless Controller can be sited up to 10 m (free air) 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".
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.

The length of pipework running from the Digital Mixer Valve to the Shower Fitting

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 5m from the valve outlet to

shower fitting.

1184347-W2-G

20

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.

The temperature indicated on the wireless controller display is measured inside the digital mixing valve and due to site conditions is not necessarily the temperature delivered at the shower outlet.

Fit 3 x AA batteries (supplied) into the wireless controller.

Depending on the type and version of your wireless controller, the software revision number (eg. r04) may be briefly displayed, the controller will then display its default time of 10:00.

Place Wireless Controller in approximate final position (no more than 10 m (free air) 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.

A sluggish response to button presses indicates poor radio communication without the out of range symbol being displayed.

If test fails, reposition unit(s) and repeat test until satisfied shower will work reliably.

Caution! Risk of product damage. Do not run

Pumped Valve (low pressure version) without a water supply for longer

than 5 minutes during test.

CONNECTING A SECOND WIRELESS CONTROLLER
The following procedure details how to assign the Wireless Controller to the Digital Mixer Valve and test the remote signal strength.
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.

Isolate electrical supply to the digital mixer valve.

Bring the wireless controller to within approximately 1 m of the digital mixer valve. Fit the three AA batteries supplied into the wireless controller.

Ensure the wireless controller LCD lights up then switch on power to the digital mixer valve.

Depending on the type and version of your wireless controller, the software revision number (eg. r04) may be briefly displayed, the controller will then display its default time of 4:00 (unregistered).

The digital mixer valve will now begin to make a noise as it resets itself and registers with the wireless controller.

Droplet symbol is displayed for approximately 30 seconds. Do not remove the batteries or switch off the digital mixer valve. Droplet symbol goes out indicating the digital mixer valve and wireless controller have been assigned to each other.

Droplet Symbol

Place wireless controller in approximate final position (no more than

10 m (free air) from digital mixer valve) and test wireless signal by

pressing " ", and adjusting the temperature. If temperature display

remains unchanged and "out of range" symbol is displayed, units Out of Range

are unable to communicate with each other.

Symbol

If test fails, reposition the controller closer to the digital mixer valve and repeat test until satisfied the shower will work reliably at all times.

1184347-W2-G

34

RE-REGISTERING
The wireless controller has previously been registered to the digital mixer at the factory, if communication problems are encountered, a re-registering of the wireless controller may be required.
A re-registering of the wireless controller must also be performed should the control PCB in the Digital Mixer Valve be replaced.
To re-register the wireless controller to the Digital Mixer Valve carry out the following sequence.
Isolate power to the Digital Mixer Valve.
Press " + " and " " buttons simultaneously until "End" is displayed on the screen.
Restore power to the digital mixer valve.
Briefly press the " + " and " " buttons, "SET" will be displayed on the screen. Note! if display reads "Err" press " " and repeat the process.

FAULT DIAGNOSIS

Read the section "Important Safety Information" first. As with most electronic equipment resetting the mixing valve by powering it down waiting a few seconds then powering it up again can often cure any issues. The Digital Mixer Valve is one part of an entire plumbing system. The fitting of a pump places additional requirements and some systems may require plumbing modifications to allow them to cope with higher flow rates. Providing the Digital Mixer Valve has been correctly installed and is operated in accordance with the instructions contained in this guide, difficulties should not arise. If any maintenance is required then it must be carried out by a competent tradesperson. Before replacing any parts make sure that the underlying cause of the malfunction has been resolved.

Warning! There are no user serviceable components beneath the cover of the appliance. Only a competent tradesperson should remove the cover.

Symptoms

Probable Cause

Possible Remedy

No shut off / Continuous flow / Shower Fitting Drain Down

Natural drain down of shower fittings
Loss of / or poor radio communications (out of range symbol maybe illuminated on wireless controller).

No Product Fault. It is natural for all shower outlets to continue to expel water for a short period of time after use. It is not uncommon for larger deluge shower heads, particularly those connected to long outlet pipe runs and therefore holding large volumes of water, to drain down water several hours after use due to the changes in the ambient temperature. We would therefore recommend that all water outlets are kept enclosed within the water catchment area.

MAINTENANCE
General
Read the section "Important Safety Information" first. Before replacing any parts ensure that the underlying cause of the malfunction has been resolved. If the shower is dismantled during installation or servicing then upon completion the product must be inspected to ensure there are no leaks. Warning! There are no user serviceable components beneath the cover of the appliance. Only a competent tradesperson should remove the cover.
Cleaning
Many household cleaners contain abrasives and chemical substances, and should not be used for cleaning plated or plastic fittings. These finishes should be cleaned with a mild washing up detergent or soap solution, and then wiped dry using a soft cloth.
Checkvalve Cartridges and Filters - Removal and Installation
Hot water entering the cold supply, or vice versa, indicates that immediate attention is necessary. This is carried out by removing and cleaning, or renewing as necessary, the checkvalve cartridges. Note! Ensure for HP Mixer Valve that flow regulator is refitted in hot supply.
Isolate the electrical and water supplies to the Digital Mixer Valve, and open an outlet fitting to release pressure and to assist the draining of residual water.
Unscrew plastic nuts and either withdraw pipework or remove Digital Mixer to gain access to the checkvalve cartridges and filters.
Use flat blade screwdriver to carefully lever cartridges out.
Remove filters and clean or renew.

Refit seals, pipes and plastic nuts. Plastic nuts require hand tightening only. Restore water supply and electrical supply. Test shower and check for leaks.
