General Information
CAKE air handling units are manufactured in accordance with valid Czech and European regulations and technical standards.
CAKE air handling units must be installed and used only in accordance with this documentation.
The customer is responsible for any damages resulting from use other than intended.
The installation and operating documentation must be available for the operating and servicing staff.
It is advisable to store this documentation close to the installed air handling unit.
When handling, installing, wiring, commissioning, repairing or servicing the CAKE air handling units, it is necessary to observe valid safety rules, standards
and generally recognized technical rules. In particular, it is necessary to use personal protective work aids (e.g. gloves) because of sharp edges and corners when
performing any handling, installing, dismounting, repairing or checking of CAKE air handling units. All equipment connections must comply with the respective safety
standards and regulations.
Any changes or modifications to individual components of the CAKE air handling units which could affect its safety and proper functioning are forbidden.
Before installing and using the CAKE air handling units, it is necessary to familiarize yourself with and observe the directions and recommendations included in the
following chapters.
The CAKE air handling units, including their individual parts, are not intended, due to their concept, for direct sale to end customers.
Each installation must be performed in accordance with a professional project created by a qualified air-handling designer who is responsible for the proper selection and
dimensioning of components concerning their suitability for a given application.
The installation and commissioning may be performed only by an authorized company licensed in accordance with generally valid regulations.
When disposing of components and materials, it is necessary to observe the respective environmental protection and waste disposal regulations. In case of final unit
liquidation, it is necessary to follow the policy of differential waste disposal. We recommend metal parts be scrapped and other parts be disposed of in accordance with
separated waste regulations.
Further information can be found in the CAKE Catalogue and in the AeroCAD designing software..
