14 Installation information for external units

Weatherproof units must not be used for any load-bearing building
functions or as a replacement for any part of the roof
(VDI 3803 5.1 / DIN EN 13053 6.2).
A level, horizontal load-bearing surface is required for siting and installing the
external units.
Base frames must be levelled horizontally (check with a spirit level).
To prevent the inspection doors from jamming, the entire base frame must sit
on the foundation; point loads are not permissible.
To prevent structure-borne noise transmission from the CRL to the building,
insert a permanently flexible intermediate layer between the foundation and
the base frame. This intermediate layer should preferably take the form of
insulation strips, fitted lengthwise below the base frame.
Roof seal
The WOLF base frame and its integration into the roof membrane must be
insulated onsite.
In the case of elevated positioning (CRL on onsite framework), the CRL must
be secured against wind load.
