3 Introduction
3.1 Introduction
All Cold Display Cabinets are synonymous in
construction and therefore you will have the
possibility of an optimum integration in a com-
plete display conception. An adjustable tem-
perature control enables you to set the desired
cooling temperature. We guarantee a constant
temperature even in case of opened doors.
The temperature rises only after some
minutes. The Cold Display Cabinets show a
high cooling performance. Within the Cold
Display Cabinets, the cooling convection pro-
vides a stable temperature. The set tempera-
tures 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
• Optically doubled foodpresentation by mirrored sliding doors
• All models are available as self-service equipment for impulse buying

6 Maintenance
Following we will show you some advices concerning maintenance, care, trouble shooting and ser-
vice for your Cold Display Cabinet.
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 things for cleaning
the unit! Never use high-pressure-, water pressure- or steam jet- cleaning ma-
chines!
 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:
 Grill- and ovencleaner:
To dispose persistend, dried-up dirt on metal surfaces.
 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 Cold Display Cabinet easily and without stripes.
