The enclosed cavity bracket is fitted before installation in order to conceal the gap at the top of the cavity left after installation.
Ensure the cavity panel bracket is positioned so that the “F” arrow is pointing towards the front of the chassis.
Firmly push the bracket so that the prongs engage with the top tabs and it clicks into place.
Ensure the prongs have not been driven down into the chassis as this will damage the lid below.
Ensure the top trim seal is facing forward after attaching the bracket.
