2. CAUTION Power to the brewer must be switched off before proceeding with installation Flush the water lines thoroughly before installing brewer Brewer should be connected to a cold water line for best operation Check incoming water for adequate pressure Water pressure should be at least 20 psi For less than a 25 ft run use 1 4 O D outside diameter copper tubing and connect to a 1 2 or larger water line For more than a 25 ft run use 3 8 O D copper tubing from a 1 2 or larger water line and provide an adapter fitting for the connection to the brewer If water pressure is more than 50 psi we strongly recommend that you install a water pressure regulator and set the water pressure below 50 psi This will prevent erratic water levels in the server Connect the incoming water line to the incoming main fitting on the back of the brewer Provide an individual water line to each machine when there are multiple units installed at the same location NOTE A shut off valve should be installed on the incoming water line in a convenient location This will allow the user to shut the water supply if needed 3 Place an empty server under brew basket Use the sight gauge to make certain it is empty 4 Plug the brewer into proper voltage circuit and switch the power ON 5 Water will automatically begin to fill the tank After water tank has filled remove the top cover of the T S S by removing the one screw in front securing it
