Additional planning notes for this installation kit
WARNING
Observe the relevant fire safety and soundproofing regulations
►
Observe the regulations concerning the fire behaviour of building materials and components
as defined in DIN 4102.
►
Observe the regulations concerning soundproofing in buildings as defined in
DIN 4109, particularly the requirements for insulation against airborne and impact sound.
►
Observe the building regulations applicable in your country.
NOTE
►
Observe the following recommendations for the use of flexible pipes as this will avoid unin-
tentional pressure losses in the flexible pipes.
— As far as possible, use flexible pipes with nominal diameter DN 75.
— Always connect two flexible pipes to the flexible pipe connection.
— Run the two flexible pipes of a flexible pipe connection in parallel to one another.
— Minimise the number of bends in the flexible pipes.

Retrospectively flush-mounting the installation kit
WARNING
►
Make sure that there are no supply lines in the vicinity of the wall breakthrough (e.g. gas,
water or power).
►
Make sure that the wall breakthrough does not affect the local static loading requirements.
► Fit a lintel if necessary.
►
If you are installing the kit retrospectively, run the flexible pipes in a suspended ceiling.
