After use

Cleaning

Use of a pressure washer is forbidden. Pressure washers generate huge amounts of water fog that might contribute to the contamination of food and food-handling surfaces over large areas in the kitchen. Switch off the appliance with the mains switch before starting to wash the kettle.

Tools not allowed for cleaning:

• pressure washer
• all metallic tools
• rough rubbing sponges
• steel wool
• abrasive detergents

Tools recommended for cleaning:

• special detergents for stainless steel
• nylon brush
• soft rubbing sponges
• other materials intended for stainless steel that do not scratch the surface

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 and 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.

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.

• Kettles with mixer and operating voltage 380 – 480V without neutral: Type B three-phase residual current device.

Installation frames

Positioning of installation frames

Single kettle

Kettle group

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 the 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.

1. Installation frame
2. Concrete casting
3. Finished floor surface
4. Floor coating

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.
