Risk assessment
The compilation of a risk assessment is strongly recommended before installing the
product. The following areas require particular consideration in addition to the informa-
tion required by the Health and Safety at Work Act.
- scalding: where appropriate or required by law a thermostatic mixing valve is to be
fitted to the hot water outlet of the cylinder
- explosion: the unit is fully equipped with all relevant safety equipment to comply with
current regulations. The correct design and function has been verified by independent
third party testing. The correct application thereof is the responsibility of the compe-
tent installer.
- water borne organisms (i.e. Legionella): if applicable a risk assessment should be
carried out following the recommendations outlined in the Approved Code of Practise
L8.
- the user preference must be considered when commissioning the system, in particular
when adjusting the solar and auxiliary system temperature and timer settings.
