This document provides installation and maintenance instructions for the Knightsbridge EX003T, EX004T, and EX005T products, which appear to be extractor fans with integrated LED lighting.
The Knightsbridge EX003T, EX004T, and EX005T are extractor fans designed for ventilation purposes, likely in bathrooms or similar areas. They are equipped with non-replaceable LED lamps, suggesting an integrated lighting function. These products are Class II double insulated and have an IPX4 rating, indicating protection against splashing water from any direction, making them suitable for damp environments. The fans feature an adjustable overrun timer, allowing users to set the fan to continue operating for a period after the main switch is turned off. This timer can be adjusted from a minimum of 2 minutes to a maximum of 30 minutes. The product is designed to be installed by cutting a 100mm diameter hole in the mounting surface and connecting to suitable ducting and an external grille or shutter.
The EX003T, EX004T, and EX005T units are designed for straightforward operation. Once installed, the fan's operation is typically linked to a light switch or a separate switch, and the integrated LED lighting will illuminate when the fan is active. A key feature is the adjustable overrun timer, which allows the fan to continue extracting air for a user-defined period after the main power is switched off. This is particularly useful for ensuring adequate ventilation in areas like bathrooms, removing moisture and odors effectively. The timer can be set using a small screwdriver, turning anti-clockwise to reduce the time and clockwise to increase it. The product can also be used in conjunction with an external PIR or sensor, provided compatibility is confirmed with the sensor manufacturer.
Maintenance for these units is relatively simple and primarily involves cleaning. The manual recommends cleaning the product with a soft, dry cloth only, explicitly advising against the use of aggressive cleaning products or solvents, as these could damage the product. The LED lamps are non-replaceable, meaning that when they reach the end of their life, the entire product should be recycled. The product has a 3-year warranty from the date of purchase, which covers defects but is invalidated by improper installation (not in accordance with IEE Wiring Regulations BS7671), improper use, or removal of the batch code. Should the product fail within the warranty period, it can be returned for a free replacement, though installation costs are not covered. The product is designed for easy access to connections by removing the front fascia and terminal cover, which facilitates installation and potential troubleshooting. Regular checks for correct operation are recommended after installation and any adjustments.
