Hi I'm about to hook this easing machine up to a cold water tap. My access is limited so I cant find a model number. I am wondering which hose connects to the cold water. Looking from the back of the machine is it the left hand side hose or the right hand side hose? Because I am not hooking it up to hot water do I need a plug or stopper for the end of the other hose? Thanks. If you could answer my question or supply me with a pdg of the users manual that would be great.
