Clamshell 3M observatory installation site
requirements
Due to the structural and technical parameters, the Clamshell observatory should be placed on a
concrete slab with a load capacity being calculated inclusive of the weight of this observatory (ap-
prox. 300kg). The slab shall have a minimum diameter of more than 2800 mm (3000 mm recom-
mended), which is the diameter of the observatory base. It is necessary to ensure that the base is
adequately levelled and the smoothness of the surface made so that the maximum deviation does
not exceed 3 mm in each of the points (in particular on the perimeter) of the slab. At the design stage
of the observatory's foundation, it is also worth considering all necessary cable routes for power and
communication, as this observatory does not provide such conduiting from outside to its inside. The
slab should be sealed to prevent uprising of moisture, and at the least, with an appropriate concrete
top sealer.
Before proceeding with the installation, we encourage you to familiarize yourself with the photo
documentation of this manual. Through the associated text and the accompanying photos, please
familiarize yourself with the details of the work carried out during each stage. Before the installation
stage, you should also plan the different stages of work and prepare all necessary materials and tools
for installation.
