winterization question

[nowrelxn]

On my 2004 Country Star 3740 I am ready to add the pink stuff, but I have a question about valve position. The water heater valves are in the bypass position, but the valve next to or near the antifreeze suction valve I have no idea what the valve is for or what position it should be in to winterize. It seems to me if in the open position the pink stuff would go into the fresh water tank which I don't want. If closed, anti freeze would not go back to the water bay. I can't find any reference to valve in the owners manuel. Hope you guys can help me out. thanks , Bob

Here is info on winterizing.
The valve will be in line with the pipe when open needs to be open to have pump suck up your anti in bucket.
Close the valve that comes from the fresh water tank.
Make sure your low point drains in water closet are closed or anti will be on the ground.
Make sure all faucets are closed or you may fill up your tub.
