2.5.6. Installation in an Old Building–Creating an Installation Opening
To minimize additional filthy and unnecessary work during installation, we recommend core
drilling to create an opening for Ventoxx RV unit. It will also make the further steps easier.
Ensure the drill bit can provide an opening of 230-240 mm. The opening should also have a
slight slope to the outside (2 degrees).
When drilling a wall opening, make sure:
That no people can be injured and/or object can be damaged by the fall out of wall
fractions;
No wires or pipes are available in the drilled wall;
That the hole does not influence the bearing capacity of the wall;
That creation of an opening has no effect on the physics of the building, e.g.,
penetration of vapour control or rain protection path;
That all necessary protective equipment is applied.
