Before  first use

Before using the kettle for the first time or if it has not been used for a long time

• Clean the pan throughout with a warm detergent solution, wiping to remove dust and contaminants from the kettle surfaces. Then dry the surfaces.

Electrically heated models:

• The kettle is in its upright and horizontal position. The kettle does not heat if it is tilted.
• The water supply (hot/cold) is open.
• No inappropriate objects in the kettle.
• Scrapers are correctly attached to the mixing tool. See ”Positioning the mixing tool and scraper”.
• The mixing tool has been locked in its place: locking part (one end of the handle) in the groove of the mixer axle, with the handle turned in a horizontal position. Secure fixing by trying to lift the tool out of the kettle by the upper blade.
• The steam generator has the right amount of water (white water level indicator light on the control panel of the Viking kettle, normally water must be refilled a few times per year).

Steam heated models:

• The kettle is in its upright and horizontal position. The kettle does not heat if it is tilted.
• The water supply (hot/cold) is open.
• No inappropriate objects in the kettle.
• Scrapers are correctly attached to the mixing tool. See ”Positioning the mixing tool and scraper”.
• The mixing tool has been locked in its place: locking part (one end of the handle) in the groove of the mixer axle, with the handle turned in a horizontal position. Secure fixing by trying to lift the tool out of the kettle by the upper blade.
• If necessary, any condensation that has accumulated in the steam jacket has been removed.

Cooking

The temperature of the steam jacket of the kettle is always at least the same as the room temperature or the same as the temperature of the cooling agent if the kettle is equipped with a cooling attachment (option).

Starting to cook

• Check that the emergency/stop button is not pressed down. The emergency/stop button can be released by turning it clockwise until it jumps up.
• Switch on the power by turning the power regulator (1) to the right (green signal lamp (2) illuminates).
• If the white water level indicator light (3) does not go off, add water to the steam generator according to instructions, see The white signal lamp (3) illuminates when the steam supply is open (steam heated models).

   3. Indicator light for low water level (electrically heated models) Indicator light “steam supply open” (steam heated models)
   4. Emergency/stop button
   5. Food temperature display

Stopping the cooking

• Turn the power regulator counterclockwise to position 0. The green indicator light goes off and the kettle stops cooking.

The kettle tilts only if the kettle is switched on. Since the kettle chills slowly, you can stop cooking and begin the simmering by decreasing the temperature.

The cooking will automatically stop when the kettle is tilted. The cooking goes on automatically when the kettle is returned to an upright position.

Cooling system (optional)

The cooling system is based on chilling tap water which is circulating inside the steam jacket. Mixing and use of scrapers makes the chilling more effective. The needed chilling time depends on the quantity of the product, the temperature at the beginning and the end of the cooling, the flow of the chilling water and its temperature, and the mixing.

Manual cooling – C1 Starting the cooling

1. Turn the power regulator to position 0.
2. Close the faucet.
3. . Remove the spray gun from the cleaning hose by pulling the connector away from the spray gun
   
4. Connect the cleaning hose to the control valve (on the right side under the kettle.
5. Open the control valve by turning the handle parallel to the valve
6. Open the jacket emptying valve (in the middle under the kettle) by turning the handle downwards.
7. Open the cold-water faucet.

Stopping the cooling

1. Close the faucet.
2. Remove the cleaning hose from the control valve.
3. Let the extra water run out of the steam jacket through the control valve. Close the control valve when the kettle is in an upright position and water stops flowing out.
4. Close the jacket emptying valve.

It takes a few minutes to let the extra water run out of the steam jacket. If you first want to empty the kettle, close the control valve before tilting it. If the control valve is open during the tilting, the steam generator may get drained of water, see “5.12.3. Filling the steam jacket” (electrically heated models).

Emptying the steam jacket (steam-heated kettles)

Open the drain valve of the steam jacket at the end of the working day so that the water that may condense in the kettle can drain into the drain. That way it won’t interfere with the next cooking event. Remember to close the drain valve the next morning before heating the kettle.

Detaching the lid parts

• Make sure the kettle is in an upright position.
• Place the lid on the kettle.
• Remove the cover of the safety grid and detach the safety grid.
• Detach the solid lid from the lifting arm by holding the lifting arm with one hand pulling the locking lever of the lid and then lifting the arm.

Refitting the lid parts

Place the solid lid on the kettle approximately in the correct position. Pull the lifting arm down over the lid. Turn the solid lid so that the guiding pin lines up with the hole in the lifting arm centerpiece

Enter the check data in the ”Maintenance information” table.

Installation

General
Please observe the instructions given in this chapter concerning the installation and adjustments that must be done before taking the kettle into use. Strict observance of the instructions prevents malfunctions and damages potentially caused by defective installation.

• Do not switch the power on if the installation place is damp (building site conditions).

Operating conditions
The kettle can be used in a normal, air-conditioned professional kitchen. The room temperature of the installation place must not exceed +40°C and the relative humidity must be less than 80% (condensation on surfaces not allowed to occur). If the temperature of the facility in winter conditions is below 0°C, the steam generator of the kettle must be drained and the kettle must be emptied to avoid damage caused by freezing. The kettle’s pipes and solenoid valve bodies must be emptied at the same time.

Possible interference from the surroundings (to the surroundings)
The kettle fulfills the requirements of the EMC directive concerning emissions and immunity to electromagnetic disturbances. In case there are electronically controlled appliances and, in particular, devices fitted with a frequency converter in the installation place, it is recommended to ensure their conformity with the relevant regulations and that their cabling has been done according to instructions.

Storage
The kettle must be stored in a dry place, at a temperature between +10 and +40°C. The kettle should be kept in its transport package during storage. If the appliance is stored in construction site conditions, special care must be taken not to damage it through other operations on the site.

• Protect the exterior of the kettle from scratches and knocks.
• Protect the kettle from construction site dust.
• Protect the kettle from sparks produced by welding, grinding, and abrasive cutting wheels. This can later cause rust spots on the stainless steel surface of the appliance.

Unpacking the appliance
The kettle should be transported in its package as close as possible to the installation place before final unpacking. Do not remove the protective film until after installation, just before the first use of the kettle.

Warning
After removing from the transport pallet, the kettle is not stable until it has been bolted down to the installation frame. It is strictly forbidden to operate or tilt the kettle before it has been fixed to the floor or the free-standing frame according to the installation instructions. When the kettle is removed from its transport pallet, it must be supported to prevent it from falling before it is fitted to the floor. If the kettle falls, this may cause injury to people or property damage.

Disposal of the package
After unpacking all packing material must be sorted and disposed of by local recycling regulations.

Residual current device recommendation

It is recommended to use a residual current device in the installation of a kettle as follows:

• Kettles without mixer: Type A residual current device.
• Kettles with mixer and operating voltage 200V, 230V, or 400/230V: Type A residual current device with high-frequency filtering or a residual current device separately approved for use with frequency converters.
• Kettles with mixer and operating voltage 380 – 480V without neutral: Type B three-phase residual current device

Positioning of installation frames

Subsurface frame cast into the floor

Installation frames are mounted according to the installation drawing, with the help of installation guides supplied with the delivery. The frames must be installed in a horizontal position and fixed so that they do not move during casting. The installation frames must be positioned so that their upper surface is 172 mm above the finished floor surface. The junction of the installation frame and floor is filled with flooring material. To achieve the best result regarding tightness, the installation frame should be filled up to the top level with concrete mass which is covered with floor coating after the installation. Make sure that the protective sleeves of the fixing bolts are in place before filling the installation frame.  The main points concerning the installation of the subsurface frame are shown in the picture below.

6. Protecting sleeve for fi xing bolt
7. Adjusting bolt

Place the kettle on the installation frame and adjust it to a horizontal position with the adjusting bolts. When the kettle is in a horizontal position, it must be fixed to the installation frames with the help of the fixing bolts. The control pillar has 4 bolts and the support pillar has 2 bolts. Tighten the adjusting nuts carefully. Do not seal the space between the kettle pillars and installation frame as there must be enough change of air.

Surface installation frame fi xed to the floor

Surface frames are mounted according to the installation drawing, with the help of installation guides supplied with the delivery. If the inclination of the floor is very steep, it may be necessary to level the surface frame closer to the horizontal by placing stainless steel spacers between the frame and the floor. This will ensure that the adjustment range of the pillars is adequate.
