3.5 Wall bracket for wall mounting Load bearing capacity: NOTE Observe the minimum clearances in section 3.3.1. Ensure that the mounting feet of the outdoor unit are at least 300 mm clear of the surrounding terrain. Take the expected snow depth at the installation site into F1 = 2.55 kN consideration.
Page 14
Installation procedure: - Observe the distances between mounting feet specific to the outdoor unit (see 3.2 Dimensions). The distances for the holes required in the wall are derived from these. - Drill the holes in the wall. - Install the wall brackets. Figure 11: Wall bracket side view - Install the 4 rubber/metal buffers for sound insulation to the wall brackets.
