That will likely leave water in the line.
Either pressurize w compressed air, open all faucets to drain all water and cycle the ice maker until no addnl water comes out.
To be really safe you could pump pink AF through FW system and then cycle ice maker.
If using pink AF you just need to flush good and sterilize in the spring before using.
