To install the HERSCHEL 3kW Variable Power Controller, follow these steps:
1. Switch off the mains supply before starting the installation.
2. Determine whether the IR load is rated below 2KW or above 2KW. If it is below 2KW, the controller can be recessed in a wall. If it is above 2KW, the unit must be mounted proud of the wall to ensure adequate cooling.

6. The installation must be carried out in accordance with the current IEE regulations (BS7671).
7. Make sure all earth wires are connected to maintain earth continuity.
8. Check all wiring and tighten the cable glands.
