After removing the protective layer you can switch off the hot air fryer.

5 tips
- Smaller ingredients usually require a slightly shorter cooking time.
- A larger amount of ingredients only requires a little more time, and a smaller amount requires a little less cooking time.
- Turning smaller ingredients several times during the cooking time results in a better and more even end result.
- Do not cook extremely fat ingredients such as sausages in the hot air fryer.
- Snacks that can be cooked in the oven, can also be cooked in the hot air fryer.
- Optimum amount for preparing crispy fries is 1000 grammes. The maximum amount is 1500 grammes.
- If necessary, use an oil spray to lightly oil the ingredients and make them even more crispy.
- Use ready-made dough for a fast and simple preparation of filled snacks. Ready-made dough also cooks faster than home-made dough.
-
Place a baking tin or oven dish in the pan if you want to make a cake or quiche, or if you want to cook delicate or filled ingredients.
-
The hot air fryer can also be used to reheat ingredients. For this, set the temperature to 150^ for 10 minutes.
- Add 3 minutes to the cooking time if the hot air fryer is still cold.
- As the turbo hot air technology immediately reheats the air in the appliance, briefly removing the pan from the hot air fryer does not have an effect on the end result.
As ingredients can differ in origin, dimension, shape and brand, Inventum is unable to indicate the most optimum setting.
6 cleaning and maintenance
Clean the hot air fryer after every use.
Before cleaning the hot air fryer, allow it to cool down fully.
Do not touch the metal interior in order to clean it, when hot air frying has just been completed.
When cleaning the pan and grid, do not use metal kitchenware or abrasive agents, as these could damage the anti-stick coating.
- Remove the plug from the socket and allow the hot air fryer to cool down fully.
Tip: remove the pan from the hot air fryer to allow the appliance to cool down faster. - Clean the exterior of the hot air fryer with a damp cloth.
- Clean the pan and grid with hot water containing a little washing-up liquid and a sponge. The pan and grid may also be cleaned in the dishwasher.
A degreaser can be used to remove remaining dirt.
Tip: fill the pan with hot water and a little washing-up liquid and allow it to soak for 10 minutes to remove persistent dirt. - Clean the interior of the appliance with hot water and a soft sponge.
- Clean the heating element with a soft washing-up brush to remove any food residues. Be careful with washing-up liquid. This could be left behind on the heating element and give a foreign taste to the ingredients.
