1. Fault diagnosis
Read the section
"Important Safety Information"
first.
Providing the shower control 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 and maintenance instructions are provided. Before
replacing any parts ensure that the underlying cause of the malfunction has been
resolved.
Shower controls are mechanical devices and should be serviced annually depending
on the water conditions. Areas of the country which are affected by hard water should
consider shorter service intervals.
When installed in very hard water areas (above 200 p.p.m. temporary hardness) your
installer may advise the installation of a water treatment device to reduce the effects
of limescale formation.
You may, if you wish, choose to engage the services of a Mira Service Engineer or
Agent, the terms of which are outlined on the back page of this guide.
