2.3 Option 2: Wall Mounting
If it is not practical to use a solid wall, the MVHR unit should be
fixed to a stud partition with a 25mm minimum thickness MDF
panel solidly fixed behind the plasterboard.
If fixing to a stud wall the MDF panel should extend, width wise, over a
minimum of 3 vertical studs with centres of no more than 400mm. Add
additional vertical supports if necessary.
Height wise, ideally, the MDF panel should extend from floor to ceiling
but as a minimum should be a least 2m high.
Fix the mounting bracket to the wall (as figure 3) and use the wall
mounted bracket to mount the unit on (as shown in figure 4).
