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
