This guidance applies to any Mi3 air purge arrangement if you want to also install a right angled mirror.
The right angled mirror with integrated air purge XXXMIACRAJ is described as not available for LTH sensing heads.
This is technically true as the item cannot be installed on to an MI3 LTH.
However, the 2 front sections can be fitted to an Mi3 LTH that has been supplied with an air purge collar.
It is necessary to discard the front part of the air purge collar and rear part of the right angled mirror accessory (air inlet).
