winterizing with compressed air

The problem is unless the ice maker is cycled several times like it is making and dropping ice cubes the pink stuff or compressed air cannot get the water out of the input hose and the ice maker. I use compressed air to pressurize the system, open the refrigerator and take off the front cover of the ice maker, rotate the gears manually to speed up the ice maker cycle. You need to do this until
all the water is out of the system and either the pink stuff or air is all you get when it is calling for ice cube water.
