Safety Instructions
Ready for use….
When the oven is correctly installed, read this manual carefully before the oven comes into service. This manual should be kept handy to persons using the oven.
Always place trays filled with hot liquid in the bottom runners of the oven chamber to avoid spilling the hot liquid on yourself when you take the tray out of the oven chamber.
Some areas on the outside of the oven may get as hot as 60°C or more, therefore, you should only touch the front of the oven.
Do not open the oven during the automatic cleaning process.
Do not store flammable materials around or under the unit.
When using the roll-in or trolley system, be aware of hot racks sliding out of the oven. Use the parking brakes on the wheels to prevent trolleys from rolling away on uneven floors.
Gas units only:
If your oven is installed under an extraction hood (recommended), the extraction hood should be switched on when the oven is running.
If your oven is connected to a chimney, the flue duct must be cleaned in compliance with local standards and regulations.
Do not block the exhaust pipes or the area around the oven.
The oven should only be used in calm conditions.
FAILURE TO COMPLY WITH THE ABOVE INSTRUCTIONS MAY INCREASE THE RISK OF FIRE!
If you smell gas….
- Turn off the gas supply immediately.
- Do not use the control panel.
- Make sure there is ample ventilation near the oven.
- Avoid open fire and sparks.
- Call the gas supplier, using an external phone.
Maintenance and repair:
Maintenance and repair should only be carried out by trained technicians.
Only use cleaning detergent that matches the specifications from the factory.

Description of Functions
Hot air
30-250°C The hot air operating mode can be used for roasting, grilling, baking and gratinating. We recommend that you keep the exhaust open when roasting products at very high temperatures. It is possible to roast breaded products such as breaded fish and breaded pork chops. For maximum effect, use enameled cast iron trays / silicone-coated baking sheets and one of the special browning fats available in the shops.
Preheating
251-300°C By setting the temperature higher than 250°C, you change to the preheating mode and PREHEAT is shown instead of HOT AIR. With this function, you preheat the empty oven. The time can be set to max. 15 minutes, and continuous operation (-:--) is not possible. The preheating mode has been changed so that the countdown does not start until the desired temperature has been reached. This is to ensure that the oven is always in the same condition when the oven is loaded, no matter the starting temperature. IT IS RECOMMENDED TO ALWAYS PREHEAT THE OVEN BEFORE USE.
Combi steaming 1 & 2
30-250°C COMBI STEAMING 1 is recommended for the roasting of all kinds of meat cuts. The pores of the meat close quickly, which prevents the juice from leaving the meat. When using long-time roasting at 80 – 130°C, COMBI STEAMING 1 helps reduce shrinkage.
COMBI STEAMING 2 is recommended for roasts that should be well-done, and if you want to use the juice in the container for gravy. At temperatures higher than 170°C, the crust of the meat becomes nice and brown. A great deal of humidity is added to the oven chamber and the amount of liquid in the tray is increased during production.
Cook & Regen
30–180°C Regenerating is a very gentle process and therefore very suitable for reheating. Use a core temperature probe to reach the perfect end temperature. For the reheating of sous-vide products, etc., follow the recommendations of the producer as to reheating. The products should not be covered up as this impedes optimum and quick reheating.
Manual humidity pulsing
When you press the key for STEAMING in the HOT AIR mode, you add humidity to the oven chamber. Humidity is added for as long as the key is held down.
Steaming in a C model
30-120°C Can be used for steaming of all types of vegetables, pasta, rice, meat, eggs and the like. If the oven chamber is 100% loaded with frozen products, hard root vegetables or meat, it will take a little longer until the oven chamber is completely filled with humidity, and the preparation time will be longer than if the oven chamber is only half full.

General recommendations for steaming
STEAMING at 100°C is recommended for all kinds of hard vegetables, rice and pasta. LOW-TEMPERATURE STEAMING at 70-80°C is recommended for the steaming of fish. FORCED STEAMING at 120°C is an aggressive and very rapid process, which should be used with care.
IT IS RECOMMENDED TO LET THE OVEN PRESTEAM FOR 8 MINUTES BEFORE LOADING IT. THIS APPLIES TO THE C MODEL AS WELL AS to the K MODEL.
Exhaust
The exhaust is usually closed in all operating modes. It is always closed in the steaming mode. When the control lamp is on, the exhaust is open. If you wish to reduce the amount of humidity in the oven chamber – when you brown, for instance – the exhaust should be open.
Fan speed
Set the FAN speed by pressing the fan key and turn the switch.
A fan speed between 20 and 50% is recommended for the baking of puff pastry, Danish pastry, cakes and small products as well as in the Delta-T and Cook-and-Hold modes. You may add 1 – 2 minutes’ preparation time for each ½ hour when low fan speed is used.
Fan speeds below 50% cannot be used at temperatures above 200°C.
A fan speed between 50 and 100% are recommended if you want a particularly juicy end product and accept a longer cooking time.
Hours, date and setting of timer
Shows the exact time and date when the oven is off. For setting of clock and timer, see USER MENU below.
Fully automatic cleaning system, CombiWash (optional extra)
The cleaning system should be used every day. You choose between levels 1, 2, 3 and 4 and possibly additional detergent, depending on how soiled the oven chamber is. The last thing you do before turning off the light in the evening is activating CombiWash. When CombiWash is finished, the computer automatically switches to an energy-saving standby function.
Follow these steps to start CombiWash:
• Cool down the oven chamber to 80°C.
• Check the level of detergent and rinse aid.
• Press PRG and turn switch until CombiWash appears in the display.
• Press STEP to select cleaning level: 0 is 2 minutes’ flushing with water – 1 is light cleaning
and 4 is very thorough cleaning. Press ALARM for additional detergent.
• Close oven door and press ON.
Steps 1 and 2 are used after steaming/roasting at low temperatures. Steps 3 and 4 are used after roasting of meat / cooking at temperatures higher than 180°C.
We recommend that the oven is cleaned on a daily basis or after each production.
