Page 4 NOTE: Water supply inlet line must meet certain minimum criteria to insure successful operation of the brewer. Bloomfield recommends 1/4" copper tubing for installation of less than 12 feet and 3/8" for more than 12 feet from a 1/2" water supply line.
Page 5: Installation Procedures
NSF requires that the brewer be able to be moved for cleaning underneath. A flex line or loops of copper tubing will satisfy this requirement. See Figure 2 below. In some areas, local codes require a backflow preventer (check valve) to be installed on the inlet water line. If a backflow preventer is used, you must install a water hammer arrester in the incoming line, between the backflow preventer and the brewer inlet, as far away from the brewer as space will allow.

Page 9: Theory Of Operation
THEORY OF OPERATION WATER FLOW Typical Brew Water Delivery System POUR-OVER FEATURE Pouring any amount of cold water into the pour-over opening and into the basin pan forces an identical amount of hot water out of the tank and through the spray head into the brew chamber.
Page 10: Hot Water Faucet
THEORY OF OPERATION (continued) HOT WATER FAUCET Typical Hot Water Faucet System The faucet water coil is submerged in the hot water tank and draws heat from the brew water. Faucet water flows through the bypass side of the water inlet and is not controlled by the solenoid valve. The faucet is at supply water pressure any time the faucet shut-off valve is OPEN.
Page 11: Brew Water Temperature Control
THEORY OF OPERATION (continued) The heating elements are energized when line power is applied to the element terminals. Water temperature is sensed by a thermobulb inserted into the water tank. This temperature signal is fed to the thermost Heat Control Diagram...
