Preparation for installing the unit
5.4. Supporting Surface and Fastening
The unit's weight requires a firm base for support, completely horizontal and leveled, assuring proper water
drainage and avoiding water accumulation.
To perform the installation calculations it is necessary to take into account the loads that affect the environment
conditions, according to the country's regulations, as well as the center of gravity specified in section "4.1. Center
of gravity". Below are the four minimum required supports.
You must follow the following stipulations when choosing the place where the unit is to be bolted in:
•
Minimum distance from the center of the bore to the edge of the concrete pad: 75 mm.
•
Diameter of the hole drilled in the concrete pad: 8 mm.
•
Minimum depth of the hole drilled in the concrete pad: 65 mm.
•
Minimum thickness of the concrete pad: 100 mm.
•
Minimum depth of anchoring bolt: 45 mm.
•
Minimum tensile strength: 7.7 kN. Security coefficient 1.5.
•
Minimum shear strength: 9.3 kN. Security coefficient 1.25.
