Bubbles, If your bay is not heated, or if you don't have the heat/weep for the triple foam, this is what I would do:
I would run antifreeze through the triple foam system, so the lines, distribution block, nor the heads could freeze and break.
I would change the triple foam pass in the wash programming to the polish pass. You can put whatever color on you wish.
The laserwash 4000, only has one out put for polish. It is either foam polish, or triple foam, whichever is programmed into the hardware/plumbing options. with a
Washworld, you can switch between these two passes whenever you want.
Some operators will switch to putting the low ph pass first, and a high ph pass second to battle salt, and winter dirt.
