2.1 Wall Mounting the MVHR Unit
Ideally the unit will be wall mounted on a solid wall.
One part of the mounting bracket (supplied) should be offered up
to the wall, ensuring it's located horizontally. Mark the fixing points
through the pre drilled holes in the bracket and install with screws (by
others), whilst ensuring the interlock side is at the top (see figure 3).
