MRXBOX-AV4

Installation Manual

Wall Mounted Unit

Loft Mounted Unit

If the AV mounts are not required fit the angle brackets as detailed 
above but omit the cross brace from the assembly, the MVHR unit 
can be fitted directly to the wall brackets using the 8x M8 screws 
pre-fitted in the base panel. 

3.4 Loft Mounting

If mounting the unit in a loft space either the floor mounting method 
can be utilised or a false wall may need to be created if no solid 

structure is available to allow installation as per the wall mounting 
method.  The false wall should be a MDF panel with a minimum 
thickness 25mm that is vertically fixed across the roof trusses to form a 
solid structure, additional vertical supports may also be necessary  
(Figure 8).
