This can be achieved if combustion air can flow through non-lockable openings, e.g. in doors, windows and via the airintake/ exhaust-air wall box or by other technical measures, such as reciprocal interlocking, etc. If the air intake is inadequate, there is a risk of poisoning from combustion gases which are drawn back into the room. An air-intake/exhaust-air wall box by itself is no guarantee that the limiting value will not be exceeded. Note: When assessing the overall requirement, the combined ventilation system for the entire household must be taken into consideration. This rule does not apply to the use of cooking appliances, such as hobs and ovens. Unrestricted operation is possible if the extractor hood is used in recirculating mode – with activated carbon filter. If the exhaust air is going to be discharged into the open, a telescopic wall box should be fitted into the outside wall. Prior to installation For operating in exhaust-air mode, a one-way flap should be mounted inside the extractor hood unless there is already one fitted in the outlet duct or wall ventilation box. If no one-way flap was enclosed with the hood, it can be obtained from a specialist retailer. Installing the one-way flap: . Snap the one-way flap into the air pipe. The two lightly sprung flaps must be able to move upwards. If the exhaust air is going to be discharged into the open, a telescopic wall box should be fitted into the outside wall. For optimum extractor hood efficiency: . Short, smooth air exhaust pipe. . As few bends in the pipe as possible. . Diameter of pipe to be as large as possible and no tight bends in pipe. If long, rough exhaust-air pipes, many pipe bends or smaller pipe diameters are used, the air extraction rate will no longer be at an optimum level and there will be an increase in noise. . Round pipes: We recommend Internal diameter: 125 mm (at least 100 mm). . Flat ducts must have an internal cross- section that equates to that of round pipes. There should be no sharp bends. l100 mm approx. 78 cm2 l125 mm approx. 113 cm2 . If pipes have different diameters: Insert sealing strip. . For exhaust-air mode, ensure that there is an adequate supply of fresh air. Connecting a l125 mm exhaust-air pipe: . Mount the pipe directly onto the air outlet on the hood. Connecting a l100 mm exhaust-air pipe: . Attach the reducing connector (enclosed or available from specialist retailer) to the air pipe and then attach to the exhaust-air duct. Prior to installation Circulating-air mode . With activated carbon filter if exhaust-air mode is not possible. 51-318 323 max. 1080 mind. 813 522 - r Electrical connection This is what you have to do: 1.Connect the green and yellow (Earth) wire to the terminal in the plug marked ‘E’ or with the symbol ( ), or coloured green or green and yellow. 2.Connect the blue (Neutral) wire to the terminal in the plug marked ‘N’ or coloured black. - 170 250 500 600/700/ 900 The extractor hood should only be connected to an earthed soc...
