Notes on installation
Foundation
Install the units and components on a surface which is smooth, level and of
adequate load-bearing strength.
The base frames must be horizontal and the foundations must be smooth-topped
and horizontal.
Make sure that the bottom of the frame is in full-face contact with the supporting
surface: spot support is not permissible.
Permanently elastic inserts must be placed between supporting surface or
foundation and air-conditioning unit or, more accurately, base frame, in order to
prevent the operating noise of the air-conditioning unit carrying into the building as
structure-borne sound. By prefence, these inserts should be in the form of
insulating strips placed lengthways under the sectional frame members.

Wooden batten
Do not set down the unit on a flat surface, as this would damage the drip nose (see
drawing). Use wooden battens of adequate thickness as supports to avoid this
difficulty.
