How to display a link to download the 1c-Bitrix file?

Question

1C-Bitrix

Catalog of instructions for equipment.
There is an infoblock with the file type property, code FILE_PDF.
Now the structure is as follows: manufacturer> instructions> detailed description
For output, I use the full catalog.
What should I write instead of a link to a detailed description in order to get a link to download a file, i.e. the structure should become:
Producer > instruction(name-link)
