Installation

The cooker hood is only intended to be installed over a hob with no more than four hob elements.
There must be a safety distance between the hotplate of the cooking pot on the hob and the bottom part of the cooker hood:
The distance must be between 65 – 75 cm. For gas appliances, 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 outlet You can operate the cooker hood in two modes:

Extraction mode
WARNING:

• The extracted air may not be vented into a flue which is used for the waste gas from appliances that 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 odors to the outside.
The extracted air is normally vented vertically. The extracted air can vented through the wall units and the loft floor to the roof ridge.
If there is a conduit under the wall units, the extraction duct can be routed so that the extracted air can be vented horizontally through the wall.

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 outside; the filtered air is released back into the room). In this case, an activated carbon filter as described under “Installing the activated carbon filter for recirculation mode”, must be used. Activated carbon filters are not supplied. You can order the carbon filter from your dealer or in our online accessories shop, www.bomann-germany.de. To order, use the reference number found under “Technical Data”.

Assembly
WARNING:

• When assembling or inserting the extraction filter as well as the carbon filter, the appliance must not be connected to the mains.

WARNING:

• Failure to use the mounting fixtures may lead to a risk of electric shock.

CAUTION:

• Before mounting, check that the wall has enough loading capacity to bear the cooker hood.
• When drilling the holes in the wall always make sure that no existing electrical cables or other objects are damaged.
• Make sure that the ventilation slots are clear of obstacles and are not covered.

NOTE: Recommendations for preparation work

•  When installing, ask another person to assist.
•  Wear protective gloves to prevent injuries from any sharp edges.

Drilling dimensions

|
---|---

• Determine the position of the cooker hood centrally above the cooking area in accordance with the specified safety distances.
  Totally 8x mounting holes with a diameter of approx. 8 mm are necessary for the wall mounting. Insert the supplied dowels (Fig. 1).

• First, drill the holes for attaching the housing according to the enclosed drilling template. Check the markings with a spirit level!
  – Turn in the upper screws 2x ST4*40mm for the suspension of the housing (C) so far that they project approx. 2~4 mm out of the wall.

• Before attaching the housing, place the two non-return valves by lightly bending them from above into the connecting piece  (extraction duct) (Fig. 2).
  For the extraction mode: Hereupon a flexible exhaust hose (supplied) with an inner diameter of 150 mm must be attached. Secure the hose with the enclosed cable tie (Fig. 2a).

• Hang up the housing. Check the secure hold and the horizontal position. To secure the housing (D),  screw in the lower screws 2x ST4*30mm through the housing (Fig. 3).

• Fix the bracket (with angle) for the upper shaft closure (A) with the screws 2x ST4*40mm after determining the extension length of the shaft cover (Fig. 4).
  For the extraction mode: Check the correct position of the exhaust hose and connect it with the outlet opening.

• Fasten the outer (lower) shaft with the bracket (without angle) using the 2x ST4*8mm self-tapping screws (Fig. 5).

• Put on the telescoped shaft unit; fix the shaft unit laterally to the housing with self-tapping screws 2x ST48mm and fix the middle shaft bracket (B) with the screws 2x ST440mm (Fig. 6).

• Pull up the inner shaft and fix the shaft cover laterally to the shaft closure bracket using self-tapping screws 2x ST4*8mm (Fig. 7).
