What electrical connection do I need to install my hood?

Connect the hood to the mains through a two-pole switch with a contact gap of at least 3mm. The hood comes with a cable and it can be fitted with a standard plug plus a 3 amp fuse, or it can be hard wired on to a 3 amp spur.

What size ducting do I need to use?

When ducting to the outside, connect the hood to the chimney using either a flexible or rigid kit measuring 125mm or 150mm - this will depend on the length of ducting you require. If you require up to 1m, a flexible kit is recommended. If it is longer than 1m and up to 3m, a rigid kit is required. The ducting kit must be positioned using sufficient pipe clamps (the ducting kit is not supplied). You must also remove any activated charcoal filters as they are not required. You can purchase Ducting Kits directly from us by calling Consumer Services on 0800 8046261 or  0370 7895107.

What can I do if I cannot duct my hood to an outside wall?

If it is not possible to duct to an outside wall, you can re-circulate the air using carbon filters that fit on to the side of the motor. Your first set of carbon filters will be included inside the hood packaging. You can purchase additional carbon filters directly from us by calling Consumer Services on 0800 8046261 or 0370 7895107.

Where can I find the serial number for my hood?

The serial number is located inside the hood which is next to the motor on a white sticker (a ten digit number - see below). It is also on the user guide.

How often do I need to change my charcoal filters?

The filters are not washable and cannot be re-used and must be replaced approximately every four months of operation, or more frequently for particularly heavy usage. To change the filters, please follow these steps:

  • Remove the metal grease filters
  • Remove the saturated activated carbon filter by releasing the fixing hooks

What are the clearances required for fitting a hood?
