3.1.2 Option 2 - Non-Solid Wall
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 (Figure 3) and use the wall
mounted bracket to mount the unit on (Figure 4).
3.2 Loft Mounting
3.2.1 Option 1 - Tank Stand
The MVHR unit should be positioned on a tank stand using the
Anti-vibration tray assembly discarding the angle brackets.
Anti-vibration tray assembly (MRXBOX-AV(3/5)) is to be purchased
separately.
3.2.2 Option 2 - Angled Brackets
The MVHR unit should be positioned on a 25mm minimum
thickness MDF panel that is vertically fixed across the roof trusses
to form a solid false wall.
Add additional vertical supports if necessary. Use the Anti-vibration
tray assembly (MRXBOX-AV(3/5)) including the angle brackets, to be
purchased separately.
