When drilling holes into concrete, we recommend<br />
always wearing safety goggles or glasses.<br />
If the unit must be secured to a wall-mounted bracket,<br />
proceed as follows:<br />
– Mark the positions of the holes for the brackets by referring<br />
to the measurements shown on the assembly<br />
dimensions diagram.<br />
– Drill the holes for the rawl plugs.<br />
– Clean the concrete dust and residues out of the holes.<br />
– Screw the rawl plugs into the holes of the mounting<br />
brackets, arrange the brackets in the proper position<br />
and hammer the plugs into the wall.<br />
– Check that the mounting brackets are properly aligned.<br />
– Carefully lift the unit and place its mounting feet on the<br />
brackets.<br />
– Secure the unit tightly to the brackets using the anchoring<br />
bolts (1) (M10 x 4), the washers (2), the vibration<br />
dampers (3) and the nuts (4).<br />

– If the external unit is still aligned in the main wind direction,<br />
a wind protection shield must be provided.<br />
– If the unit is frequently exposed to heavy snowfall: install<br />
a canopy above the unit to protect it from rain or<br />
snow. Be careful not to obstruct the flow of air around<br />
the unit.<br />
