IMPORTANT SAFEGUARDS

HOUSEHOLD USE ONLY

13. When using this appliance, provide at least 15cm of space above and on all sides for adequate air circulation
14. DO NOT cover the air intake vent or air outlet while the unit is operating. Doing so will prevent even cooking and may damage the unit or cause it to overheat.

CLEANING & MAINTENANCE

The unit should be cleaned thoroughly after every use. Unplug the unit from the plug socket and wait until the unit is fully cooled before cleaning .

If food residue is stuck on the drawers, crisper plates & stacked meal racks place them in a sink filled with warm, soapy water and allow to soak.

HELPFUL TIPS

1. For best results, when using Double Stack Pro always place vegetables/ starch in the bottom half of the drawers on the crisper plate and proteins in the upper half using the stacked meal racks.
2. For consistent browning, make sure ingredients are arranged in an even layer with no overlapping. If ingredients are overlapping, make sure to shake them at regular intervals throughout the set cooking time.
3. Cook temperature and time can be adjusted at any time during cooking. Simply select the zone you want to adjust, Press TEMP, and use the dial to set the desired temperature or press TIME and use the dial to set the time.
4. To convert recipes from your conventional oven, reduce the temperature by 10°C. Check food frequently to avoid overcooking.
5. Occasionally, the fan from the air fryer will blow lightweight foods around. To alleviate this, secure foods (like the top slice of bread on a sandwich) with cocktail sticks.
6. The crisper plates & stacked meal racks elevate ingredients in the drawers so air can circulate under and around ingredients for even, crisp results.
7. After selecting a cooking function, you can press STOP/START to begin cooking immediately. The unit will run at the default temperature and time.
8. For best results with fresh vegetables and potatoes, use at least 1 tablespoon of oil. Add more oil as desired to achieve the preferred level of crispiness.
9. For best results, check progress throughout cooking and remove food when the desired level of brownness has been achieved. We recommend using an instant-read thermometer to monitor the internal temperature of meat & fish.
10. For best results, remove food immediately after the cooking time is complete to avoid overcooking.
11. For best results with Double Stack Meals, it is not recommended to mix fresh and frozen ingredients within the same drawer. For the best output, cook frozen food loads within 1 drawer.

TROUBLESHOOTING GUIDE

How do I adjust the temperature or time while using a single zone?
Select the active zone, then press TEMP and use the dial to adjust the temperature or press TIME and use the dial to adjust the time.

How do I adjust the temperature or time while using dual zones?
Select the desired zone, press TEMP and use the dial to adjust the temperature or press TIME and use the dial to adjust the time.

Does the unit need to pre-heat?
The unit does not need to be pre-heated.

Can I cook different foods in each zone and not worry about cross- contamination?
Yes, both zones are self-contained with separate heating elements and fans.

How do I pause the countdown?
The countdown timer will pause automatically when you remove the drawers from the unit. Reinsert the drawer within 15 minutes to resume cooking or the zone with the drawer open will be cancelled.

How do I pause one zone when using both zones?
To pause one zone, first press the zone button then press STOP/START. To pause both zones simply press STOP/START.

Is the drawer safe to put on my worktop?
The drawer will heat up during cooking. Use caution when handling, and place on heat-resistant surfaces only.

When should I use the crisper plate?
Use the crisper plate when you want food to come out crispy. The plate elevates the food in the drawer so that air can flow under and around it to cook ingredients evenly.

When should I use the stacked meal racks?
Use the stacked meal racks when you want to cook two layers of food in one drawer. Place vegetables/starch in the bottom half of the drawer and protein in the upper half of the drawer. It is not recommended to mix fresh and frozen ingredients within the same drawer. For the best output, cook frozen food loads within 1 drawer.

Why didn’t my food cook fully?
Make sure the drawer is fully inserted during cooking. For consistent browning, make sure ingredients are arranged in an even layer on the bottom of the drawer with no overlapping. Shake drawer to toss ingredients for even crispiness. Cook temperature and time can be adjusted at any time during cooking. Simply select the desired zone, press TEMP and use the dial to adjust the temperature or press TIME and use the dial to adjust the time.

Why is my food burned?
For best results, check progress throughout cooking and remove food when the desired level of brownness has been achieved. Remove food immediately after the cook time is complete to avoid overcooking.

Why do some ingredients blow around when air frying?
Occasionally, the fan from the air fryer will blow lightweight foods around. Use wooden cocktail sticks to secure loose lightweight food, like the top slice of bread on a sandwich.

Can I air fry wet, battered ingredients?
Yes, but use the proper breading technique. It is important to coat foods first with flour, then with egg, and then with breadcrumbs. Press breadcrumbs firmly onto the battered ingredients, so crumbs won’t be blown off by the fan.

Why is the unit beeping?
Either the food is finished cooking or it indicates that the other zone has started cooking.

Why did the display screen go black?
The unit is in standby mode. Press the power button to turn it back on.

Why is there an “E” message on the display screen?
The unit is not functioning properly. Please contact Customer Service at 0800 862 0453.
