Typical Examples of Poor Plumbing and Installation Practices
DO NOT:
• Install the Digital Mixer Valve where it can become frozen
• Position the Digital Mixer Valve where maintenance access is poor
• 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 user interface 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, 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
• Fit plastic pipework unless rigidly supported
