HP500 backflush

Does anyone have instructions on how to backflush a HP500? I think you disconnect the oil cooler hose and run water through there but not sure which hose on the bottom to disconnect to let the water flow out. I tried searching for a water flow diagram but couldn't find one.

Thanks!

The hose goes from sea pump to oil cooler. Pull both ends of this hose and flush it. You can also pull cap on cooler and make sure no pieces/debris are in there

Thanks for the info. If hooking a hose up to flush, do you connect it to end of the oil cooler and flush opposite normal water flow?
