Frequently Asked Questions - DU 668 G BOMANN

What is the difference between extraction and recirculation mode?

In extraction mode, air is vented outside through a duct. In recirculation mode, air is filtered through an activated carbon filter and returned to the kitchen. Recirculation requires purchasing carbon filters separately.

How do I clean the aluminum grease filter?

Remove the filter by sliding back the lock and pulling it forward. Clean it monthly in hot water with neutral detergent, or in the dishwasher up to 60°C. Let it dry before reinstalling.

How often should the activated carbon filter be replaced?

Replace the activated carbon filter at least every six months, regardless of use. Order part no. KF 561 (set of 2) from Bomann.

What are the installation safety distances?

The minimum distance between the hob and the bottom of the hood is 45–55 cm for electric hobs and at least 65 cm for gas hobs. Follow the gas cooker’s instructions if a larger distance is specified.

Can I use the hood without a duct?

Yes, you can use recirculation mode without an external duct. You must install two activated carbon filters (not included). The filtered air is released back into the room.

How do I replace the LED lighting?

Allow the lamps to cool. Use a suitable tool to remove the lamp, disconnect the cable, and replace with a new 22x00552W DED LED lamp. Ensure it clicks into place.

Why is my hood not working?

Check if the unit is plugged in and the fuse is working. Ensure the power level is set. If still not working, contact an authorized technician.

What should I do if the hood is noisy or not extracting efficiently?

Clean the grease filter if dirty. Check the carbon filter (if in recirculation mode). Ensure the air outlet is not blocked and the correct fan speed is selected.

Is the hood suitable for use above a gas stove?

Yes, but maintain a minimum distance of 65 cm. Never flambé under the hood. Always supervise frying due to fire hazard.

Can I install the hood myself?

Installation requires drilling and electrical connection. Follow the manual’s instructions carefully. For safety, have a qualified electrician handle the electrical connection.

Installation

There must be a safety distance between the hotplate of the cooking pot on the hob and the bottom part of the extractor hood:

The distance must be between 45 The 55 distance of gas appliances, 45 the distance must be at least 65 cm. If the installation instructions for the gas cooker specify a greater distance, this distance must be taken into consideration.

Selecting the fume outletSelecting the fume outlet

You can operate the extractor hood in two modes:

Extraction mode Extraction mode

WARNING: WARNING:

• The extracted air may not be vented into a flue which is used for the waste gas from appliances which are powered by gas or other fuels.
• When venting the extracted air, comply with the regulations of the relevant local authorities.

The hood has an upper air outlet to vent cooking odours to the outside.

- The extracted air is normally vented vertically. If there is a suitable loft space above your kitch-

en, the extracted air is vented through the wall units and the loft floor to the roof ridge.

Architectural cross-section diagram showing brick wall and insulation layers with a magnified inset of insulation (no text or symbols)

- If there is a conduit in your kitchen under the wall units, the extraction duct can be routed so that the extracted

air can be vented horizontally through the wall.

Recirculation mode Recirculation mode

If you do not have a direct extraction vent to the outside; the hood can also work in recirculation mode (i.e. without an extraction vent to the out side; the filtered air is released back into the room). In this case, two activated carbon filter as de scribed uncler "Installing the activated car bon filter for recirculation mode", must be used.

The activated carbon filter are not supplied. You can order the car bon filter from your dealer or in our online accessories shop, www.bomann.dewToorderusedthe reference number found under "Technical Data".
