Providing the Mira Advance 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 for
whom the fault diagnosis chart, wiring diagram and maintenance instructions are
provided. Before replacing any parts ensure that the underlying cause of the malfunction
