Overview of modes

Steam mode (30 °C to 130 °C)

The high performance fresh steam generator with new steam control always produces hygienic fresh steam. You can cook without adding water and without waiting for the water to boil. Constant cooking cabinet temperatures and maximum possible steam saturation guarantee a uniform and highly gentle cooking process. Appetising colours, bite and retained nutrients and vitamins are guaranteed, particularly for vegetables. The steaming mode is ideal for stewing, blanching, steaming, poaching, heating through, simmering, brewing and soaking.

Convection mode (30 °C to 300 °C)

The hot air circulated at high speed flows around the food from all sides. The meat protein sets immediately, so it remains wonderfully succulent on the inside. Constant hot air at up to 300 °C is not simply a technical detail; the necessary reserve power is there even for full loads. This is the only way to get succulently browned pan-fried dishes, frozen convenience or light baked goods.

Combination of steam and convection mode (30 °C to 300 °C)

Combination mode marries all the benefits of the hot steam, such as short cooking time, minimal cooking losses, succulence, with the advantages of convection, which is responsible for creating the intense aroma, appetising colour and crispy crusts. In this way you will avoid up to 50 % of the normal cooking losses, without turning the food and with considerably shorter cooking times.

Finishing mode (30 °C to 300 °C)

Finishing means the conscious separation of production and service. From side dishes through to the complete menu, with the optimum climate you will heat the food you prepared and then chilled up to serving temperature very quickly

- whether it is on trays, plates or in containers. You gain flexibility, and your customers enjoy the experience more as the food is no longer kept warm for long periods, thus losing quality.

32 / 112

Overview of modes

"Cool down"

With the Cool Down function, you can quickly and gently cool a hot cooking cabinet, e.g. for low temperature cooking or manual cleaning.

Programming/Programme Start/ Cleaning"

Using the programming function, create and save manual programmes. For recurring cooking processes, there are 100 programme slots with up to 6 cooking steps available. This ensures consistent quality - even when using temporary staff. The automatic cleaning programme restores the hygienic initial condition of your appliance without additional staff expenditure.

33 / 112

Steam Mode

In the “steam” cooking mode, the steam generator generates hygienic fresh steam. You can set the cooking cabinet temperature from 86 °F - 266 °F / 30 °C -130 ℃ . Cooking methods: Steaming, stewing, blanching, simmering, soaking, vacuum cooking, thawing, preserving

Steam Mode

To get the most out of your appliance, check daily the types of food which can be cooked together using “steam” .

Remember that fish, meat, vegetables, side dishes and fruit can be cooked together (as long as they are all being prepared by the same method). Potatoes are cooked in perforated GN containers, the perforations let the steam circulate and give faster, more intensive cooking. Vegetable stock can be collected by inserting a container on the bottom rack. It is better to use two shallower GN containers rather than one high one => this reduces bulk and avoids heavy layers of food.

Dumplings should be placed in a shallow solid GN container, not too close together. Rice and cereals are the only foods to which you should add water: 1 part grain, 1.5 to 2 parts

water.

Tomatoes are very easy to skin: “steam” for approx. 1 min, then plunge into cold water. Approximate cooking cabinet temperatures

Soup garnishes: 167 °F - 194 °F (75 °C - 90 °C) Fish, shellfish and crustaceans: 149 °F - 194 °F (65 °C - 90 °C) Meat and sausages: 162 °F - 167 °F (72 °C - 75 °C) Light meat: 167 °F - 185 °F (75 °C - 85 °C) Dark meat: 176 °F - 194 °F (80 °C - 90 °C) Poultry: 176 °F (80 °C) Desserts: 149 °F - 194 °F (65 °C - 90 °C)

Seasoning

Season with care. Low cooking temperatures intensify the characteristic taste of seasonings. When vacuum cooking be sure to add the exact amount of fumet, essence or reduction!

Preserving fruit/vegetables

Cover the food with hot or cold liquid, depending on the firmness of the raw product and the type of preserve you want. The diameter of the preserving jars used should not exceed

3.9" (100 mm). The cooking temperature will depend on the type of product (ripeness, size of pieces). Approximate temperature: 165 °F -210 °F (74 °C - 99 °C). Please note: The jars must not be closed.

General notes on pan-frying

- Preheat to as high a temperature as possible (572 °F / 300 °C) to build up sufficient stored

heat.

- Load as quickly as possible, in order to minimise cabinet temperature drop. 

Breaded products

All types of breadcrumb coating can be used. Browning is improved by brushing with fat or a blend of paprika and oil. Rule of thumb: allow approx. 8 to 10 minutes per 0.39" (1 cm) thickness of meat

Preheat: to 572 °F / 300 °C (at least until heating indicator light goes out). Optimum cut thickness: 0.59" to 0.79" (1.5 to 2 cm). Accessories: Roasting and baking tray or granite-enamelled container. For even browning on

the top and bottom surfaces, make sure that the slices are of the same thickness or the same size. 

Gratinate

Light and dark meat dishes, fish, mussels, asparagus, chicory, broccoli, fennel, tomatoes, toast. Preheat: to 572 °F /300 °C (at least until heating indicator light goes out). Set to desired temperature after loading. Accessories: e.g. grids or containers (0.79" /20 mm) for gratinating toast, steaks and soups. 

Baking

Preheat: to baking temperature. For a full load you may need to select a higher preheating temperature.

Baking temperature: approx. 68 °F - 77 °F (20 °C -25°C) lower than in a conventional oven. For frozen convenience products preheat to 572 °F (300 °C). Defrost frozen rolls and leave to rise for a short time. Accessories: Use perforated Teflon-coated baking trays, baking and roasting trays or granite

enamelled GN containers.

Attention!

- For hygiene reasons and to prevent malfunctions it is essential to clean your appliance every day - risk of fire!

- Your appliance must be cleaned every day, even if it is only operated in "Steam" mode.

- Only use cleaner and rinse aid tabs from the appliance manufacturer. The use of other cleaning chemicals can damage the appliance. Liability is not assumed for damages as a consequence!

- If you use excessive cleaning chemicals, this can cause foaming.

- Never place the tabs in the hot cooking cabinet (> 50 °C).

- Leave the appliance door slightly open if it is going to be idle for a prolonged period (e.g. overnight).

- Cleaning the press-fit door gasket daily will extend the service life. Use a soft cloth and washingup liquid to clean the press-fit door gasket - do not use a scouring agent.

- Clean the glass panes inside and out and the outer panels of the appliance, ideally using a soft, damp cloth. Do not use any abrasive or aggressive cleaning agents. Use mild household washing-up liquid and regularly clean the steel with a steel cleaning agent.

To clean the appliance, the cooking cabinet temperature must be below 50 °C (see Cool Down section).. You can choose between CLE1 (for heavy soiling), CLE2 (for light soiling) and CLE3 (Interim clean).

Cleaning the cooking cabinet seal

When the unit will remain unused for a longer period of time (e.g., overnight), leave the unit door slightly ajar. Cleaning the seal every day helps prolong its life. Clean the cooking cabinet seal using a soft cloth and detergent—do not use abrasive cleaners!

Cleaning glass surfaces

The inside glass panes are very easy to clean because the unit doors are equipped with hinged glass panes expressly for this purpose. 

For XS units (6 2/3 GN)

To clean the glass, open the unit door until it clicks into place at an angle of 120°; after that, press the two stops and swing the first glass panes open. Clean the surfaces of the two panes with a soft cloth or a sponge, using glass cleaner or mild household dish soap. After that, press the two stops again and then swing the second pane open so that you can clean the second intermediate space and the LED covers (if necessary - see below) using appropriate cleaning agents. 

For all other units (6x1/1 GN through 20x2/1 GN)

Open the unit door until it clicks into place at an angle of 120°; after that, press the two stops and swing the inner glass pane open. Clean the surfaces of the inner and outer panes with a soft cloth or a sponge, using glass cleaner or mild household dish soap.

Do not use the integrated hand shower or other pressurized cleaners to clean the door. Use only a soft cloth or sponge to clean the glass panes and the LED covers. Do not use scouring pads or abrasive cleaners. Use only gentle cleaning agents such as glass cleaner or dish soap. Never apply cleaning agents to hot surfaces. Allow the door to cool completely before cleaning. Always rinse cleaning agents away completely before heating up the unit. Do not use any of the following cleaning agents:

- Abrasive cleaning agents

- Strong acids or bases

- Undiluted alcohols

- Acetone or methanol

- Oven cleaner, grill cleaner

- Benzine, benzene, toluene, or xylene

98 / 112

Building services

Cleaning the LED covers (only XS units 6 2/3 GN)

The LED lighting covers are positioned behind the inner and middle glass panes, so they are well-protected against soiling, but the area may still require cleaning on occasion. Open the inner and middle panes to expose the LED covers so that they can be cleaned. Clean the surfaces of the LED units using a soft cloth, sponge, or paper towel, applying gentle pressure. 

When cleaning the LED covers, keep the following in mind:

The transparent part of the LED cover is a high-quality component that ensures proper illumination and light distribution within the unit. Never clean this area using scouring pads, abrasive cleaners, or other aggressive agents such as strong acids or bases, undiluted alcohols, acetone, methanol, oven cleaner, benzine, benzene, toluene, or xylene. Use only gentle, diluted cleaning agents, e.g., alcohol-based cleaners such as glass cleaner (ethanol-based) or dish soap. Never apply cleaning agents to hot surfaces - allow the door to cool before cleaning. Apply cleaning agents for a brief period of time and then rinse the area with water. Never heat up the unit unless cleanser has been completely rinsed away.

Rinsing the drip pan and drain channel (tabletop units only)

Clean the drain channel of the drip pan every day if the unit is frequently being used for grilling or preparing foods containing a large amount of grease or gelatin. Use only the manufacturer’s cleaning brush (item no: 60.75.779) in order to prevent damage to the drain system. Carefully guide the cleaning brush into the drain opening up to the mark (Model 61/101: to the marker flag; Model 62/102: to the plastic handle) and clear any blockages. Avoid making jerky movements, which could damage the unit or the brush. After that, rinse the drain channel with 1-2 liters of warm water. Do not use the spray jet on the hand shower for this.

Servicing the air ﬁlter

Tabletop unit Model 6 x 2/3 GN:

To loosen the air filter, insert a suitable object (such as a coin or a screwdriver) into the central slot on the front, and push inward. This will release the catch on the air filter. Draw the filter downward at an angle and out of the unit.

Clean the air filter in the dishwasher (not CleanJet and then let it dry. If the air filter is still sticky and soiled after cleaning, replace it. Insert the air filter into the unit from underneath at an angle. Press the plastic filter casing upward until it clicks into place. Air filter no.: 40.04.771
