Providing the shower 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
maintenance instructions are provided. Before replacing any parts ensure that the
underlying cause of the malfunction has been resolved.
