The water must be potable, free of corrosive chemicals,

sand, dirt, or other contaminates. It is up to the

installer to ensure the water does not contain corrosive

chemicals, or elements that can aect or damage the

heat exchanger. Water that contains chemicals

exceeding the levels below aect and damage the heat
