Using Your Air Fryer Oven

The appliance is suitable for frying, roasting, baking, grilling, drying, or warming food.

USING THE ACCESSORIES

• Oil Drip Tray:
  Insert the oil drip tray into the bottom of the cooking space for food residues such as dripping fat or crumbs to collect in.
• Air Flow Racks:
  1. The air flow racks are intended for drying. However, they can also be used for crisping, warming up, etc.
  2. Slide the air flow racks onto the rails in the cooking space.
     The heating element is located at the top of the cooking space. Therefore, the higher up an air flow rack is placed, the more intense the heat is from above.
     • In the top section, the food is cooked faster and crispier.
     • The middle position should be chosen to achieve even heating from all sides.
     • The bottom rails are suitable for gentle cooking.

ROTISSERIE

The rotisserie fork consists of the shaft and two rotisserie fork heads. The rotisserie is suitable for grilling large pieces of meat, e.g., chicken, pork with a maximum weight of 1.3 Kg.

Assemble the rotisserie fork and insert it into the appliance:

1. Slide one of the rotisserie fork heads onto the shaft and secure it in place with the locking screw.
2. Slide the food for grilling onto the shaft.
3. Slide the other rotisserie fork head onto the shaft and food and secure it in place with the locking screw.
4. Push one end of the shaft into the round holder on the side of the cooking space. Then hang the other end of the shaft into the support on the opposite side of the cooking space.
5. Check that it fits securely. The rotisserie fork must not be able to rotate about its own axis when the appliance is switched off. If this is not the case, push the shaft deeper into the round holder.
6. Once the rotisserie fork is installed, press the key on the unit’s control panel to activate the rotation function. If the rotisserie has been installed correctly, it will begin to rotate.
   • If the rotisserie fork does not begin to rotate once the key has been pressed, pull it out of the air fryer and repeat the steps detailed above, taking care to ensure the shaft is pushed all the way into the slot on the body of the appliance.
7. After use, remove the hot rotisserie fork from the cooking space using the handle (see the Rotisserie Handle section).
   CAUTION: Wear oven gloves to remove the rotisserie forks.

GUIDANCE NOTES

• The shaft contains a small round notch for the tip of the locking screw. In the case of smaller pieces of food, the rotisserie fork heads can be secured more centrally on the shaft.
  (See illustration A).

  

• The shaft contains two small round notches marking the outermost position of the locking screws. The locking screws must not be attached any further than the outer ends of the shaft to ensure smooth operation.
• DO NOT place any pieces of meat that are too large onto the rotisserie fork as this could hinder rotation. It may be necessary to truss a chicken.
• The key can be pressed at any time during cooking to stop rotation, if required.

ROTISSERIE HANDLE

Use the rotisserie handle to remove the rotisserie from the cooking space:

1. Place the ends of the rotisserie handle under the shaft.
2. First, lift the shaft from the support and pull it forwards a little until the other end of the shaft is released from the holder.
3. Carefully lift the rotisserie out of the cooking space and place it down on a heat-resistant surface.

KEBAB SKEWERS (Optional Accessory)

Assemble the skewer rack:

1. Place the skewer rack discs onto the shaft, ensuring the flat faces of the discs face inwards.
2. Thread food onto the separate skewers and place them onto the skewer rack by slotting the sharp end of the skewer into the narrow slot and the hooked end of the skewer into the shaped slots. Squeeze and tilt the hook downwards to lock into place.
3. Place the rack into the oven. Insert the shaft end with just one notch into the holder on the side of the oven walls. Push the rack into the holder as far as it will go.
4. Hang the other end of the shaft (with two notches) into the support on the opposite side of the oven.
5. Check that the rack fits securely. It must not be able to rotate about its own axis when the appliance is switched off. If this is not the case, push the shaft deeper into the holder.
6. After use, remove the rack using the handle (see the Rotisserie Handle section).
   CAUTION: Wear oven gloves to remove the rack and the grilled items.

7. Squeeze and tilt the hook upwards to remove the skewers from the rack.

   

Frying Basket (Optional Accessory)

The rotating basket turns during cooking to ensure that the food crisps on all sides. The rotating basket is particularly suitable for preparing chips or other potato products, small pieces of vegetables and meat, as well as frozen products such as chicken nuggets or onion rings.

1. Place the shaft through the basket so that the shaft end with one notch exits the side of the basket with the L-shaped metal attachment.
2. Open the rotating basket.
3. Place food into the rotating basket. To ensure food is cooked evenly, the basket should be no more than ¾ full with food.
4. Close the basket, ensuring that the catch is shut.
5. Insert the side of the rotating basket with the L-shaped metal attachment and the shaft end with just one notch into the holder on the side of the oven walls. Push into the holder as far as it will go.
6. Hang the other end of the shaft (with two notches) into the support on the opposite side of the cooking space.
7. Check that the rotating basket fits securely. It must not be able to rotate about its own axis when the appliance is switched off. If this is not the case, push the shaft deeper into the holder.

8. After use, remove the hot rotating basket from the cooking space using the handle (see the Rotisserie Handle section).

   

   

   CAUTION: Wear oven gloves to open and empty the rotating basket.

Cooking with the Air Fryer Oven

PRE-HEATING

Some food is best cooked once the air fryer oven has been pre-heated (until the heating indicator goes off):

GETTING THE BEST RESULTS FROM YOUR AIR FRYER OVEN

Cooking Time

• The cooking time will depend on the size of your ingredients. Smaller sizes may require a shorter cooking time.
• In general, the cooking times are shorter than in a conventional oven. Start with shorter cooking times and adapt the cooking times to your personal taste.
• While becoming familiar with the appliance, it is advisable to check the condition of the food during cooking to ensure that it does not burn. To do this, open the air fryer oven door or switch on the light using the key.

Turning and Rotating Food

• "Flipping" or turning smaller sized foods halfway through the cooking process ensures that all the pieces are evenly fried.
• It may be necessary to rotate the air flow racks during the cooking process to ensure even cooking of all foods. The Air Flow Racks section in the Using the Accessories section details the heat variations within the appliance.

Accessories

• If using a cooking vessel on the air flow racks, non-stick coated or enamel-coated ovenware is recommended for greater heat transfer.
  NOTE: Using cooking vessels may affect the cooking due to the reduction in airflow.
• If using air flow racks without a cooking vessel, keep in mind that food residues may drip onto food items on shelves below.

Food Tips

• Snacks that can be prepared in an oven can also be prepared in the air fryer oven.
• There is no need to add any oil to frozen chips as most frozen products are generally pre-fried. When preparing frozen chips or other frozen convenience products, follow the manufacturer’s specifications on the packaging. Be cautious of using extremely greasy ingredients, such as sausages, in the air fryer oven.
• The air fryer oven can be used to reheat food; set the temperature to 150°C for up to 10 minutes.
