4 hot air frying

The air fryer can prepare a large range of ingredients. See the section SETTINGS for an indication of the timing and temperature settings.

1. Check that the voltage in your home corresponds with the voltage printed on the bottom of the appliance and plug the fryer into an earthed socket.
2. Carefully pull the pan out of the air fryer by the handle.
3. Place the ingredients in the basket. Attention: never exceed the recommended amount or fill the basket over the maximum, as this could affect the quality of the end result.

4. Slide the pan back into the air fryer properly. Never use the pan without the basket. If the pan is not placed into the air fryer correctly, the appliance will not function.
   Caution: do not touch the pan during and sometime after use, as it gets very hot. Only hold the pan by the handle.

5. Turn the temperature knob to the required temperature. An indication of the correct temperatures can be found in the section SETTINGS.

6. Determine the required preparation time for the ingredients with the table in the section SETTINGS.

7. To switch on the appliance, turn the timer knob to the required preparation time.

Tip: add 3 minutes to the preparation time when the appliance is cold.

If you want to preheat the appliance without ingredients, turn the timer knob to more than 3 minutes and wait until the thermostat light goes out (after aproxx. 3 minutes). Then remove the pan, fill the basket and turn the timer knob to the required preparation time.

- The on/off control light and the thermostat light go on.

- The timer starts counting down the set preparation time.

- During the hot air frying process, the thermostat light lights up and goes out from time to time. This indicates that the heating element is switched on and off to maintain a constant temperature.

- Excess oil from the ingredients is collected on the bottom of the pan.

1. Some ingredients require shaking halfway through the preparation time. Take the pan out of the appliance by the handle and shake it with the ingredients. Then slide the pan back into the air fryer and continue to bake.

Attention: do not press the unlock button on the handle.

1. When you hear the timer signal, the set preparation time has elapsed. Pull the pan out of the appliance and place it on a heat-resistant surface.

Note: you can also switch off the appliance manually. To do this, turn the temperature knob to 0, or pull out the pan directly.

1. Check if the ingredients are ready.

If the ingredients are not ready yet, simply slide the pan back into the appliance and set the timer to a few more minutes.

1. To remove small ingredients (e.g. fries), press the basket release button and lift the basket out of the pan.

Do not turn the basket upside down with the pan still attached to it, as any excess oil that has been collected on the bottom of the pan will leak onto the ingredients.

After hot air frying, the pan and the ingredients are hot. Depending on the type of the ingredients in the air fryer, steam may escape from the pan.

After hot air frying, the pan and the inside metal cover are hot, avoid touching these parts.

1. Empty the basket into a bowl or onto a plate. Use a pair of tongs to lift the ingredients out of the basket with large or fragile ingredients.

2. When a portion of ingredients is ready, the air fryer is instantly ready for preparing another portion.

5 settings

The chart in the chapter will help you to select the best settings for the ingredients you want to prepare.

Attention: these settings are indications. As ingredients differ in origin, size, shape as well as brand, we cannot guarantee the best setting for your ingredients.

Because the rapid hot air technology instantly reheats the air inside the appliance, pulling the pan briefly out of the appliance during hot air frying barely disturbs the process.

TIPS

• Smaller ingredients usually require a slightly shorter preparation time than larger ingredients.
• A larger amount of ingredients only requires a slightly longer preparation time, a smaller amount of ingredients only requires a slightly shorter preparation time.
• Shaking smaller ingredients a few times starting halfway through the preparation time optimizes the end result and can help prevent unevenly fried ingredients.
• Do not prepare extremely greasy ingredients such as sausages in the air fryer.
• Snacks that can be prepared in a oven can also be prepared in the air fryer.
• GF250HL: The optimal amount for preparing crispy fries is 500 grams. The maximum amount is 800 grams.
  GF400HL: The optimal amount for preparing crispy fries is 700 grams. The maximum amount is 1500 grams.
• Use pre-made dough to prepare filled snacks quickly and easily. Pre-made dough also requires a shorter preparation time than home-made dough.
• Place a baking tin or oven dish in the air fryer if you want to bake a cake or quiche or if you want to fry fragile ingredients or filled ingredients.
• You can also use the air fryer to reheat ingredients. To reheat ingredients, set the temperature to 150°C for up to 10 minutes.

home-made fries

To make home-made fries, follow the steps below:

1. Peel the potatoes and cut them into sticks.
2. Wash the potato sticks thoroughly and dry them with kitchen paper.
3. Pour half a tablespoon in a bowl and place the sticks on top. Mix until the sticks are coated with oil.
4. Remove the sticks from the bowl with your fingers or a kitchen utensil so that excess oil stays behind in the bowl. Put the sticks in the basket. Note: do not tilt the bowl to put all the sticks in the basket in one go. Any excess oil will end up on the bottom of the pan.
5. Fry the potato sticks according to the instructions in this chapter.

tips

• To reduce the weight, you can remove the basket from the pan and shake just the basket. To do so, pull the pan out of the appliance, place it on a heat-resistant surface and press the button of the handle.
• If you set the timer to half the preparation time, you hear the timer signal when you have to shake the ingredients. However, this means that you have to set the timer again to the remaining preparation time after shaking.
• If you set the timer to full preparation time, there is no timer signal during cooking before finishing, you can pull out the pan at any time to check the ingredients cooking condition, the power will shut down automatically and resume after sliding the pan back into the appliance (Attention: the timer still is counting down).

Clean the appliance after every use.

Before cleaning the air fryer, leave it to cool down completely.

Do not touch the hot metal inside before cleaning immediately after frying.

Do not use metal kitchen utensils or abrasive cleaning materials to clean the pan and the basket, as this may damage the non-stick coating.

1. Unplug the appliance and leave the air fryer to cool down completely.

Note: remove the pan to let the air fryer cool down more quickly.

1. Wipe the outside of the appliance with a moist cloth.

2. Clean the pan and the basket with hot water, some washing-up liquid and a non-abrasive sponge. The pan and the basket are dishwasher-safe.

A degreasing liquid can be used to remove any remaining dirt.

Note: fill the pan with hot water and some washing-up liquid and let it soak for 10 minutes to remove tough dirt.

1. Clean the inside of the appliance with hot water and a soft sponge.
2. Clean the heating element with a soft cleaning brush to remove any food residues. Do not use washing-up liquid. This can give a tang to the ingredients.

Never immerse the appliance, power cord and plug in water or any other liquid to protect against electrical hazards.

Before storing the air fryer, let the appliance completely cool down and unplug it. Check whether all the parts are clean and dry. Store the air fryer in a clean and dry place.

7 troubleshooting

Problem Possible cause Solution
The air fryer does not function. The appliance is not plugged in. Plug the appliance in an earthed wall socket.
The ingredients fried with the air fryer are not done.	The amount of ingredients in the basket is too big.	Put smaller batches of ingredients in the basket. Smaller batches are fried more evenly.
	The set temperature is too low. Turn the temperature knob to the required temperature setting (see chapter 5 - SETTINGS)
	The preparation time is too short. Turn the timer knob to the required preparation time (see chapter 5 - SETTINGS)
The ingredients are fried unevenly in the air fryer.	Certain types of ingredients need to be shaken halfway through the preparation time.	Ingredients that lie on top of or across each other (e.g. fries) need to be shaken halfway through the preparation time (see chapter 5 - SETTINGS).
Fried snacks are not crispy when they come out of the air fryer.	The snacks are meant to be fried in a traditional deep fat fryer.	Use oven snacks or lightly brush some oil onto the snacks for a crispier result.
The pan will not slide properly into the appliance.	There are too much ingredients in the basket.	Do not fill the basket beyond in full. Keep the indicated amounts in the table in chapter 5 - SETTINGS.
	The basket is not placed correctly in the pan.	Push the basket into the pan until you hear a click.
White smoke is coming out of the appliance.	You are preparing greasy ingredients. When you fry greasy ingredients in the air fryer, a large amount of oil will leak into the pan. The oil produces white smoke and the pan may heat up more than usual. This does not affect the appliance or the end result.
	The pan still contains grease residues from the previous use.	White smoke is caused by grease heating up in the pan, make sure you clean the pan properly after each use.
Fresh fries are fried unevenly in the air fryer.	You did not use the right type of potato. Use fresh potatoes and make sure they stay firm during frying.
	You did not rinse the potato sticks properly before you fried them.	Rinse the potato sticks properly to remove starch from the outside of the sticks.
Fresh fries are not crispy when they come out of the air fryer.	The crispiness of the fries depends on the amount of oil and water in the fries.	Make sure the potato sticks are dried properly before you add the oil.
		Cut the potato sticks smaller for a crispier result.
		Add a bit more oil for a crispier result.
