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 fitted 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 specification. Hot water 55˚C to 65˚C, Cold
water 1˚C to 20˚C.
• To reduce any effects of water hammer secure all pipe work rigidly.
• Do not fit 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 flushed 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, qualified 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 fluctuations.
Supply pipework layout must be arranged to minimize the effect 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 flushed 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 fitted 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.
