1.9 INTENDED USE
The units are designed specially for use in food and serving counters, as standalone units or for multi-unit installation (unit
tower).
They are to keep packaged foodstuffs warm and to display them (up to a product temperature of around 70°C depending on
the foodstuff, the packaging and the ambient conditions) at controlled temperature ranges of up to 95°C air temperature
(temperature at the exhaust opening) in the cabinet. The units are used to keep foodstuffs warm, not to warm them up or cook
them, and are also not intended for mass storage of foodstuffs.
•Only suitable packaging may be used to store the products. For more information, contact our your specialist dealer
or the manufacturer.
•The hot air curtain must not be impeded / interrupted / blocked with products.
•Pay attention to the maximum filling height of 150 mm for the cabinet (measured from the black glass plate →the
base).
•Only place pre-heated products into the cabinet.
•If cold and hot ingredients are to be combined, as is the case with hamburgers for example, temperature fluctuations
may occur in the product –the prescribed product core temperature may therefore no longer be attainable.
•The owner is obliged to ensure that products are stored correctly.
1.9.1 MANUFACTURER’S RECOMMENDATION
•Foodstuffs that dry out quickly (e.g. baked breads, baguettes, etc.) should not be stored for more than 2 hours after
being placed in the cabinet.
•If the optional accessories are being used (snack waves, etc.), only products for which no excessively high
temperatures are prescribed to keep them warm should be placed in the cabinet.
•The optimum operating ambient temperature is between + 18°C to +20°C. The lower the ambient temperature, the
lower the product temperature may be.
Ensure the following prior to switching on and switching off:
The units must be complete. The unit is a built-in unit or a standalone unit and must be closed or built in on all sides. Unit
stability must be guaranteed and tipping prevented by correct installation in accordance with section 2.4.
In order to save energy, we recommend switching the units off when not in use (when empty) outside of opening hours. Wait
until the required temperature has been reached before filling the units.
NOTE
All of the manufacturer’s specifications must be complied with. These specifications include the ambient
temperature, conditions in the installation environment and connections to be used.
Proper use also includes observing the installation and operating manual, as well as complying with inspection and
maintenance conditions. Any other use requires written approval from the manufacturer.
Improper use can pose risks to people and cause the unit to be damaged.
A control is used to set the cabinet temperature, and this control may only be used after reading and understanding the
documentation. If the unit is stopped or taken out of service, the points in section 1.8 must be complied with.
Furthermore, a failure to comply with the proper use renders liability and warranty claims void. The unit may only be operated
under the usage conditions prescribed in the operating manual.
