[. . . ] When making the electrical connections, check that the current socket has a ground connection. The following warning is valid in the United Kingdom only: in case your cable is not furnished with a plug, read the following instructions; as the colours of the wires in the mains lead of this appliance may not correspond with the coloured markings identifying the terminals in your plug, proceed as follows: ?the wire which is coloured green and yellow must be connected to the terminal in the plug which is marked with the ], or coloured green or letter E or by the earth symbol [ green and yellow; ?the wire which is coloured blue must be connected to the terminal which is marked with the letter N or coloured black; ? [. . . ] In case your appliance is not furnished with a non separating flexible cable and has no plug, or has not got any other device ensuring omnipolar disconnection from the electricity main, with a contact opening distance of at least 3 mm, such separating device ensuring disconnection from the main must be included in the fixed installation. If your unit features a power lead and plug, position this so the plug is accessible. Always switch off the electricity supply before carrying out any cleaning or servicing operations on the appliance. USE Avoid using materials which could cause spurts of flame (flambes) near the appliance. When frying, take particular care to prevent oil and grease from catching fire. To avoid possible risks of fire always comply with the indicated instructions when cleaning anti-grease filters and when removing grease deposits from the appliance. mAINTENANCE Thorough servicing guarantees correct and long-lasting operation. Any fat deposits should be removed from the appliance periodically depending on amount of use (at least every 2 months). To clean painted appliances on the outside, use a cloth dipped in lukewarm water and neutral detergent. To clean steel, copper or brass appliances on the outside, it is always best to use specific products, following the instructions on the products themselves. To clean the inside of the appliance, use a cloth (or brush) dipped in denatured ethyl alcohol. For the filtering version use a flexible tube to connect the hood flange to the top of the wall unit. When the installation has been completed, remount the front door and make the electrical connection. OPERATION IMPORTANT: to ensure correct operation of the grease filter LED visual alarm, ALWAYS switch off the motor by pressing button B = motor ON/OFF switch.

If the synthetic filter is not totally white, but has got coloured parts (stripes or spots), this means it is a saturation detector filter, it should therefore be changed when the coloured parts can be seen from the outside or the apparatus. To remove the synthetic filters: open the door pulling it forwards and push the 2 plastic catches upwards (Fig. [. . . ]
