The AL400122 can be combined perfectly with all Vario cooktops 400 series and 400 series cooktops, up to a maximum cooktops width of 120 cm. It is recommended to use two remote fan units so that sufficient vapour captation will be ensured. In EU countries, due to legislation EU 66/2014, only air recirculation is recommended.

Depending on the type of installation, the corresponding accessories must be ordered separately. For optimum performance in air recirculation, an outflow surface area of at least 800 cm² is recommended (400 cm² for each remote fan unit). Operation of Vario cooking appliances is only possible without appliance cover.

The table ventilation must have its own worktop cut-out. The bearing capacity and stability, in the case of thin worktops in particular, must be supported using suitable substructures, taking into account the appliance weight and additional loads. The remaining surface of the worktop (minimum 50 mm) between the cut-outs must be reinforced with a support; furniture support AA 409 401/431 is recommended.

Installation is possible in worktops made of stone, synthetics or solid wood. Heat resistance and watertight sealing of the cut edges must be observed. For other materials, the worktop manufacturer should be consulted. Depending on the type of installation, ovens can be combined with the table ventilation.

When installing a ventilation hood with air extraction mode and a chimney-vented fireplace, the hood’s power supply line needs to feature a suitable safety switch. The control unit should be accessible and be secured to a panel of the cabinet that avoids any risk of flooding.

The power levels of the AL400122 depend on the connected remote fan unit. The equivalent ducting length to ensure good performance is Lmax 19 m. Flexible connection options to the remote fan unit are available at the bottom, at the front or at the back, and in all options it is possible to have space for drawers in front of the table ventilation.
