Adding refresh() to an existing command

Question

Just a quick question with regards to jQuery as javascript is not my forte.

I need to add:

BackgroundCheck.refresh();

Into the first line of the code below before the 'fadein' kicks in:

        $('.icon-scroll').delay(2000).fadeIn('slow', function(){
            $('.icon-scroll').delay(4000).fadeOut('slow'); 
        });

        

I just don't know how to add this command into the existing code $('.icon-scroll').delay(2000).fadeIn('slow', function(){

I tried adding it on top or right below the first line but it doesn't seem to work the way I want.
