How do I connect the water supply line to the refrigerator?

Use ¼ inch (6.4 mm) OD copper or stainless steel tubing with water pressure between 30 and 100 psi; plastic tubing is not recommended. Disconnect the refrigerator from electrical power before connecting, flush the supply line until water is clear, then connect and tighten the compression nut half a turn past finger tight — do not over-tighten. After connecting, turn on the water supply, check for leaks, reconnect power, and turn on the ice maker. (Pages 17-18)
