General Safety Precautions
Do not undertake work outdoors at height unless you are
competent in the use of ladders and other access equipment.
Always use correct equipment, observe appropriate safety
precautions and follow manufacturers instructions. If in doubt
consult a professional installer.
Before starting installation check structure is sound and check for
hidden wiring or plumbing.
When working on an installation outside, beware of overhead power lines.
Observe safe working practices, tread carefully on roofs and ensure
adequate lighting is available if working in loft or roof space.
Before making any connections switch electricity off at the mains.
To avoid injury always route cables or wiring carefully. Ensure cable
is correctly routed before fixing into position, taking care not to
overtighten cable clips.
This kit contains small parts - keep out of reach of children.
After installation make regular maintenance checks for wear and tear.
