The Digital Mixer is one part of an entire plumbing system. The fitting of a pump
places additional requirements on the plumbing system. Some systems may require
plumbing modifications to allow them to cope with higher flow rates.
Providing the Digital Mixer 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.
