The Metos Chef 50, 50T are intended for baking buns, bread, rolls and other similar products. Chef 50, 50T can also be used for cooking food.

The Metos Chef 240 is intended for cooking and browning food, baking and for heating convenience meals and keeping food warm.

3.1. Intended use of the appliance

Use of the appliance for any other purposes than that mentioned above is prohibited.

The manufacturer shall not be held liable for any situations which may arise from failure to comply with the warnings and instructions given in this manual.

3.1.1. Use for other purposes

In addition to a single oven, two or three ovens can be stacked on top of another on a stand forming a roasting and baking station. One or two convection ovens can also be replaced by a Chef 220 oven or a Chef 200 proving cabinet.

This manual covers the Chef 40, 40T, Chef 50, 50T and Chef 240 convection ovens, while Chef 220 and Chef 200 have their own manuals.

3.2. Operating principle

In convection ovens, cooking takes place by hot air circulating around the food. Rapidly circulating air is fanned around the food from all sides to cook effectively and evenly. Moisture can be used to further boost cooking of certain products (see “Cooking tips”).This also affects food quality and reduces weight loss. The oven is also ﬁtted with a steamoutlet valve for removing superﬂuous steam from the oven chamber.

4. Operation instructions

4.1. Before using the appliance

There is a slight smell of metal and thermal insulation when the oven is heated for the ﬁrsttime. This is completely normal and disappears by heating the oven. Before using the oven for the ﬁrst time, heat it to a temperature of +250ºC until the smell disappears.

4.1.1. Choice of the ovenware, Chef 40, 40T

It is possible to use ﬁve baking sheets (GN1/1) at the same time.

4.1.2. Choice of the ovenware, Chef 50, 50T

It is possible to use four baking sheets (600 x 450 mm) at the same time.

4.1.3. Choice of the ovenware, Chef 240

Choose the ovenware according to the type of food to be cooked:

Casseroles: GN1/1-65 mm (RST 18/8). Avoid 100 mm deep containers as these may give an uneven result. Pancakes: GN1/1-40 mm, aluminium. Pasties, buns, rolls: GN2/1 bak-ing plate, aluminium. Convenience meals: GN2/1 grid, RST 18/8

4.1.4. How to ﬁll the oven, Chef 40, 40T and 50, 50T

Fill the guide rails so as to leave at least a 20 mm gap between the ovenware, so the products will bake evenly. When ﬁlling the baking plate, leave a generous space between the products. These two points are essential to achieve a good baking result.

4.1.5. How to ﬁll the oven, Chef 240

Correct ﬁlling of the oven and the right choice of ovenware ensure the best possible cooking result.

Fill the guide rails leaving a sufﬁcient gap between the ovenware, so the products will cook evenly. If you use grids or baking plates, leave a generous space between the products you are cooking. These two points are essential to achieve a good cooking result.

2.4.2013

METOS CONVECTION OVEN CHEF, CHEF T

4.2. Operation procedures

4.2.1. Before cooking, Chef 40, 40T and 50, 50T

The oven must be preheated to cooking temperature before actual cooking begins. This is to heat the whole oven to the correct temperature so as to ensure the best possible cooking results.

• Put the guide rails in place.

• Set the timer (see Figure “Control panel switches”) at 20 minutes. When setting the time, ﬁrst turn

the timer past the desired setting value and then back to the desired value.

• Set the temperature at 250ºC, if the oven is loaded to max. capacity with cold products. (After loading the oven, required roasting temperature is set.) If smaller amounts of products are roasted, the preheating can be done using a smaller temperature difference.

• The oven is ready for use when the timer signals to tell you that time is up.

• When the door is closed, the oven will remain hot for a long time, even though it is not switched on.

4.2.2. Before cooking, Chef 240

The oven must be preheated to cooking temperature before actual cooking begins. This is to heat the whole oven to the correct temperature so as to ensure the best possible cooking results.

• Choose the right guide rails: 2 pairs of rails for baking, roasting and browning, 3 pairs of rails for baking small and light products.

• Set the timer (see Figure “Control panel switches”) at 20 minutes. When setting the time, ﬁrst turn the timer past the desired setting value and then back to the desired value.

• The oven is ready for use when the timer signals to tell you that time is up.

• When the door is closed, the oven will remain hot for a long time, even though it is not switched on.

4.2.3. How to select cooking temperature, Chef 240, 40, 40T and 50, 50T

Because a convection oven is so effective, cooking temperatures should be around 20ºC lower than they would in a conventional oven.

Cooking time depends on food quality, weight and thickness. The shallower the food to be cooked is, the shorter the cooking time. See “Cooking tips” later in this chapter.

2.4.2013

METOS CONVECTION OVEN CHEF, CHEF T

4.2.4. Using the oven

If the oven is used on board a ship, the oven guide rails must be positioned inside the oven so that the clip which prevents the ovenware from sliding out of the guide is on the doorside. Should the clip be against the rear wall inside the oven, remove the rails and swap them around.

There may be a main supply disconnection switch ﬁtted near the oven (usually on the wall) when the oven was installed. Ensure that this switch is in the ON position.

Oven functions are operated from the control panel (see Figure “Control panel switches”in Chapter “Functional description/Operating principle”).

4.2.5. Cooking, Chef 240, 40, 40T and 50, 50T

• Carefully preheat the oven as instructed in “Before cooking”.

• Turn the handle clockwise (or counter clockwise) to open the oven door. To close the door, push the

handle until you hear a distinct click.

• Put the food in the oven.

• Set the timer (see Figure “Control panel switches”) at the required cooking time and the thermostat

switch at the required cooking temperature.

• When the set cooking time is over, the heating and the fan will switch off automatically and a signal will tell you that you can take the food out of the oven.

• Switch the power off at the thermostat, where upon the buzzer also stops sounding.

• Open the door. Beware of escaping steam.

In the event of uneven cooking check that

• the oven has been installed horizontally

• the oven has been preheated as instructed

• the cooking temperature is correct

• the oven has been correctly ﬁlled.

In the event of interruptions in the electricity supply when the oven is in use, turn all switches to the 0 position to prevent unexpected start-up of the oven when the electricity supply is restored.

4.2.6. Moistening function

In the moistening function, water passes through the nozzle to the hot air of the fan where it vaporises and is distributed evenly inside the oven by currents of air.

Moisturing varies a little depending on network pressure. The effect of pressure on the amount of moisturing water is given in the table below.

Moistening / pressure

Chef 40, 40T, 50, 50T Chef 240

Adjustment range

Factory setting

<_3bar 500 ml/min 10-220 ml/min 45 ml/min

2 bar 455 ml/min 8-180 ml/min 35 ml/min

1 bar 230 ml/min 5-80 ml/min 20 ml/min

It is not allowed to use the moistening function at temperatures below 150°C, because part of the water does not then vaporise.

Non-vaporised water will splash in droplets onto the surfaces of the oven chamber, keeping them moist and ﬁnally gathering into pools on the chamber bottom. If water is very calcareous (hard), calcareous deposits will form onto the oven surfaces.

As to corrosion, the most harmful substances present in the water are chloride-ions. When non-vaporised water gradually vaporises, the chloride content of water will increase, intensifying the corrosive effect. Corrosion caused by chlorides is a chemical process,which only occurs in humid conditions. The longer the surfaces remain moist, the greateris the corrosive effect.

To avoid corrosion, do not use the moistening function at low temperatures (below150°C) and make sure that the moistening water vaporises immediately so that the oven’s interior surfaces remain as dry as possible.

4.2.7. Use of the moistening function, Chef 40, 40T and 50, 50T

Switch the moistening function on by turning the switch in a clockwise direction and keepit there (see Figure “Control panel switches”).

If moistening is needed for a longer time, it is recommended to divide it into short moistening and break periods to prevent water from gathering on the oven bottom when the moistening function is on.

Use of the moistening function in the early stage of baking reduces weight loss and drying out and produces a crusty surface.

Do not open the oven door immediately after moistening to avoid scalding by hot steam.

2.4.2013

METOS CONVECTION OVEN CHEF, CHEF T

4.2.8. Use of the moistening function, Chef 240

Switch the moistening function on by turning the switch in a clockwise direction (see Figure “Control panel switches”).

If needed, the factory setting of the moistening device can be adjusted by authorised service personnel.

If water gathers on the oven bottom during moistening, it is advisable to reduce the factory setting so that all the water vaporises immediately.

Use of the moistening function reduces weight loss and drying out and heats the food faster.

We recommend the moistening function be used as follows:

When heating food throughout the heating process. Remove lids from individually packed foods such as meatballs. Heating times will be reduced by 1/3-1/2 of those given. To cook joints and meat loaf, but not browning. To cook casseroles (steam panel closed). When baking, because moisture promotes rising. Use in the early stage of baking.

Open the oven door cautiously, because hot steam can easily cause scalding.

4.2.9. Steam removal

The steam exhaust valve (see Figure “Control panel switches”) is normally closed to prevent moisture from being lost from inside the oven.

If there is too much steam inside the oven (water droplets on the bottom of cake tins), open the steam exhaust valve to remove the moisture.

The steam exhaust valve should be fully open when roasting and cooking gratin dishes.

4.3. After use

4.3.1. Cleaning

Use of a hose or pressure washer to clean the appliance is forbidden.

Before cleaning the oven, please remember that it remains hot for a long time after use.

Ovens are electrical appliances, which means that there are restrictions regarding cleaning them with water. Use of water is permitted when cleaning the oven inside. Clean the outside of the oven with a damp cloth only to avoid water getting into the air inlets. Depending on how dirty the oven is, use an alkaline substance which can be diluted in a spray bottle to loosen grease.

It is of utmost importance to keep the interior surfaces of an oven clean. A thin passive layer will form on stainless steel surfaces, giving a protective layer to the steel. A dirty oven and chlorides crystallized on the surface, combined with a humid and warm environment, break the protective passive layer, not allowing it to regenerate and thus exposing the interior surfaces to corrosion. Regular cleaning decreases the collection of chlorideions on the oven’s interior surfaces. The more you use the moistening function in food preparation, the more important it is to clean the oven daily and regularly to prevent corrosion.

Daily cleaning

Spray diluted detergent solution into the inside of the cold (below +50ºC) oven, and on the inside surface of the door. Heat the oven to about +50ºC (not essential), switch off at the mains and let the detergent work for about 15 minutes. Use a brush or cleaning pad to scrub the burned places. Avoid the use of steel wool and abrasive pads and use chemical cleaners instead of mechanical ones. Once a surface is scratched, dirt sticks to it much more easily.

Wipe the loosened dirt and detergent carefully with a damp cloth. After washing, ﬁrst dry the oven with a cloth and then by heating at +150ºC for 5 minutes. Check that the steam exhaust valve is in the open position.

Cleaning the guide rails and the suction plate

When cleaning the oven thoroughly, loosen, soak and wash the guide rails and the suction plate. The guide rails and the suction plate can be easily removed and conveniently washed in a dishwasher.

To remove the guide rails:

• Lift the guide rails upwards.

• Pull the guide rails towards the centre of the oven chamber.

• Pull the guide rails out of the oven chamber.

To remove the suction plate:

• With your ﬁngers unscrew the two screws ﬁxing the suction plate to the bottom ofthe oven chamber.

• With your ﬁngers unscrew the two screws ﬁxing the suction plate to the ceiling ofthe oven chamber.

• Pull the suction plate out of the oven chamber.

After cleaning, replace the suction plate and the guide rails in the opposite order.

METOS CONVECTION OVEN CHEF, CHEF T

Cleaning of external surfaces of the door

The external glass of the door can be opened for cleaning. Unscrew the two screws shownin the picture and turn the external glass carefully downward until it stays fully open.Spray diluted detergent solution onto the door’s metal surfaces between the glasses and onto the glass surfaces. Let the detergent work for about 15 minutes. Wipe the loosened dirt and detergent carefully with a damp cloth. After cleaning, return the external glass toits former position. Fit the screws in place and tighten carefully.

5.2.2. Installation of a Chef oven group

The appliances can be assembled to form combinations of two or three units by stacking them on top of each other. The stand height for two units is 660 mm and for three units200 mm. For assembly of the oven group a special spare parts kit is necessary. The kit can be ordered separately. Code for the spare parts kit is 3752352. Refer to your local supplierfor details.

Assembly of the oven group can be carried out by an agent authorized by the manufactur-er

5.3. Positioning the appliance

When installing the appliance, care should be given to ensure that there is a free passage of cooling air around the appliance and that there are no other sources of heat near the cooling vents.

Because of the heat and steam arising during cooking, it is recommended to place the oven under an exhaust hood.

It is important to install the appliance in a level, horizontal position. Tilting and unevenness, however slight, may have an adverse effect on the cooking result.

The appliance must be placed on a ﬂat surface and levelled into a horizontal position by using the adjustment screws on the legs. For the best result, check horizontality by the guide rails inside the oven.

To achieve a horizontal position, adjust the screws on the legs of the stand.

5.4. Electrical connections

Should maintenance require the appliance to be tested before all the protective coverings are in place, please be particularly careful of the moving parts inside the casing as well as of live parts.

To facilitate future maintenance and to increase safety, install a separate disconnection switch for the oven in the immediate vicinity of the appliance.

The switch should disconnect the appliance completely from the mains supply.

The supply cable inlet is in the back right-hand corner of the oven and the connectionpoint inside the oven. The side casing needs to be open to connect the oven to the mains.

All information needed to connect the appliance is to be found on the name plate, the connection diagram and the installation drawing.

5.5. Water connections

Connection to the cold water supply must be made by a 12 mm thick pressure resistant hose ﬁtted with an R3/4” connector. The water connection must be ﬁtted with a shut-offvalve and a non-return valve.

Rinse the water hose before making the water connection.

5.5.1. Requirements for water quality

A general assumption is that the appliance material is defective when hard-to-clean deposits or corrosion appear on the surface. Usually this is, however, due to the aggressive nature of water and harmful components it contains as well as to negligence of cleaning the appliance.

Quality criteria, both national and based on EU directives, exist for tap water. E.g. calciumand magnesium that cause water hardness are useful substances for health, but in appliances they cause harmful scale. Chlorides, on the other hand, provide a favourable soil for corrosion even in small contents when combined with a humid and warm environment.The smaller chloride content, the better is the situation. In order to guarantee a long service life for an appliance we recommend the following limit values for water quality.

Chloride content (Cl¯ ) < 25 mg/l Conductibility < 40mS/m pH 7-8,8 Hardness 2-5°dH = 0,4 - 0,7 - 0,9 mmol/l

If you use water softeners, remember to take care of appropriate maintenance and service of the water softener as well as the appliance itself.

5.6. Draining

The water is drained off by gravity through a drain hose connected to the oven drain tube by means of an R3/8 thread connector.

The drain line must be outside the perimeter of the oven.

It is prohibited to ﬁt the drain hose directly with the drain line. The air clearance of at least 25 mm between the hose end and the drain line (drain cup) must be ensured.

5.7. Installation completion

When the installation is complete, check that all connections have been correctly made.

5.8. Test-run

Please read the safety and operation instructions as well as the functional description before testing the oven. As for other appliances possibly included in the baking station, see separate manuals.

Test the oven once it has been connected to the mains electricity.

Check that

• the green oven-on lamp lights up when the oven is switched on

• the yellow thermostat lamp lights up when the thermostat is turned in a clockwise direction

• the yellow thermostat lamp goes out once the oven has heated up and reached the temperature set

• the green moistening lamp lights up when the switch is turned in a clockwise direction and moisture

enters the inside of the oven (200°C). In case the water does not vaporise completely and splashes in droplets onto the chamber walls collecting water on the oven bottom, the moistening device needs to be adjusted.

• the fan wheel is rotating and changes the rotation direction with approx. one minute intervals

• the door switch deactivates the fan and heating when the door is opened

• the guide rails and the air suction plate are properly in place

• the drip tray is properly in place under the oven door.

Fasten the side casing.

6. Troubleshooting

If the appliance fails to work, check to ensure that

it has been used according to instructions all removable parts are in place the disconnection switch (usually on a wall or in the immediate vicinity of the oven) is in the ON position the fuses (overload protection) have not blown in the fuse box. Ask a qualiﬁed person to check overload protection.

Should the oven still not work, contact an authorised agent. Before phoning, make sure you have at hand the appliance type and serial number to be found on the name plate on the right front corner of the appliance.

This appliance does not contain parts which can be serviced by the user. Maintenance must be carried out by an authorised agent
