This product must be installed by a competent and qualified electrician in accordance with IEE Wiring Regulations and current Building Regulations. The system operates at Safety Extra Low Voltage via the supplied LED driver and must never be connected directly to the mains. This product is not suitable for dimming.
Installation
Before installation, ensure the power is switched off at the mains. Plan the layout to ensure cables reach the LED driver and maintain adequate ventilation. The unit must be mounted out of arms reach and at least 100mm from a joist. The distance between units must be at least 0.5m.
Cut-out dimensions:
- 90957: 105mm diameter (Minimum cavity depth: 63mm)

It is recommended to cut the hole slightly smaller than specified and file it until the unit fits snugly. Position the LED driver near the mains outlet, pull the mains wire through the hole, and connect as detailed in the wiring section. Push the spring clips upwards to fit the unit into the ceiling hole.
Wiring
This unit is double insulated and does not require connection to an Earth circuit. If incoming earth cables are present, they must be joined together and well insulated with good quality insulation tape to ensure earth continuity. Ensure connections are tight and no loose strands are left out of the connection block.
Safety and Care
Always disconnect the product from the mains at least 10 minutes before any maintenance or adjustment to allow it to cool down. Clean with a soft dry cloth; do not use solvents or abrasive cleaners. If the unit is damaged, it cannot be serviced and must be scrapped.
