3 Introduction
3.1 Introduction
All Deli Cold Cabinets are synonymous in con-
struction and therefore you will have the pos-
sibility of an optimum integration in a complete
display conception. An adjustable temperature
control enables you to set the desired cooling
temperature. We guarantee a constant tem-
perature even in case of opened doors. The
temperature rises only after some minutes.
The Deli Cold Cabinets show a high cooling
performance. Within the Deli Cold Cabinets,
the cooling convection provides a stable tem-
perature. The set temperatures are reached
within one hour, the degree of condensation is
low.
The maximum holding time depends on the kind of product and on the products
starting temperature. It might be limited by national or local regulations. Never
equip the cabinet with warm or hot products.
3.2 Special features
• Ergonomic, stylish design
• Maximum product visibility by curved front glass
• Decorative stand (optional with bag shelf and bumpers)
• Easy handling of the curved front glass by pressure lifts
• Optimized product-presentation by variable 100mm GN-pan equipment or decorative bowls
• Meeting the hygienic requirements in accordance with HACCP
• All models are available as self-service equipment for impulse buying

Please learn the electrical and technical data of your unit from the nameplate.
• Check whether your lokal electrical power supply is in accordance with the data on the name
plate.
• Make sure the supply cable is protected as listed below:
(5- wire, min. cross-section 1,5) separatly with 16 Amps.
• The power supply needs to be manufactured from flexible cable. It is to be routed to prevent any
contact to hot parts.

6 Maintenance
Following we will show you some advices concerning maintenance, care, trouble shooting and ser-
vice for your Deli Cold Display.
6.1 Cleaning and care
6.1.1 Safety advices
• Before you start to clean and care switch off the appliance and disconnect it from
the mains.
• Do not use inflammable detergents, sharp-edged or metallic items for cleaning the
unit! Never use high-pressure-, water pressure- or steam jet- cleaning machines!
• Wear acidproof gloves while cleaning the parts to prevent skin irritations.
6.1.2 General Recommendations
• The unit has to be cleaned daily.
• Only use cleaners that are appropriate for food (neutral or alkaline detergents),
even if there are plain and persistent residues.
• After cleaning with special cleaners you have to wash all parts with clear water
and dry them afterwards so that there are no residues of the cleaner on these
parts.
• It is absolutely necessary to watch out for some fundamental things to keep this
longliving high-grade-steel-machine working:
- always keep the high-grade-steel surface clean.
- watch out that there is always enough fresh air on the surface
- never contact the surface with rusty material
• Never use bleaching or chlorine cleaners.
• Take brushes with plastic or natural bristles for cleaning.
6.1.3 Detergents
To make the cleaning fast and easy we have integrated some cleaners in our pro-
gram:
• Intensiv-cleaner:
Detergent for metal- and plastic-surfaces.
• Glass-cleaner:
Removes fat from glass-surfaces.
• Stainless steel-cleaner
You have to spray this from a distance of app. 25 cm on the surface and wipe it
off with a dry cleaning rag. If you want to clean only small parts you have to spray
it directly on the cleaning rag and wipe it off this way. With this method it is possi-
ble to clean the Deli Cold Display easily and without stripes.

6.1.4 Special cleaning hints
Please find below some special cleaning tips for this specific unit:
• Lamps:
To be cleaned only with soft paper or cloth and alcohol.
• Glass:
Lift the curved front glass to clean the inside. Due to the pressure lifts it is easy to
lift the curved front glass. However, the opened glass should be secured by hand.
Remove dust and dirt from the glass surface with soft cloth to avoid scratches.
• Drawers, GN-Pans:
Easily removable without tools for seperate cleaning (picture A).
• air-openings,evaporator:
All air openings as well as the evaporator need to be cleaned regularly to ensure
convection and cooling performance of the unit and also to minimize prevention of
dirt particles into the fan and lamina of the evaporator. Damages to the unit can
be prevented that way. The evaporator is covered with an evaporator cover plate.
After removing the GN-pans and the air guiding plates this unit can be lifted and
needs to be secured during the cleaning process (We recommend to involve a
second person for this process). The cleaning can be effected with a vacuum
cleaner or a brush. Be careful to prevent injuries or damage of the unit. Please
follow our instructions A-F.
