Installation and Assembly
NOTE
Particular care must be taken to ensure compliance with the precise dimensions of roof openings and
to ensure that the foundation is level.
Structure-borne sound attenuation
In order to reduce the transfer of vibrations from the unit to the supporting structure, anti-vibration
mounts and structure-borne sound attenuating mats must be installed.
– We recommend that the foundation is isolated from the unit using rubber plates, for example, where
the unit is installed on level ground and no special structure-borne sound isolation requirements
exist.
– We recommend the use of commercially available spring elements for ceiling mounting.
– For very special acoustic requirements please consult an acoustics engineer to select the most
suitable structure-borne sound attenuation method.
Assembling the unit
NOTE
For detailed information, please refer only to the documentation enclosed with the unit. Data sheet,
installation instructions, small parts and accessories supplied loose can be found in the unit part
specified in the parts list.
DAMAGE TO THE UNIT!
Fittings/attachments etc. not provided by the manufacturer that could cause a leak must not be
