Brew Tank Fill Tubes: (there will be one per group, the picture above shows a 2 group) Heat exchangers exit
on the le side of the steam tank and copper tubes deliver the water to the brew tanks.
Brew Tank: Synesso™’s brew tanks are enrely stainless steel, welded internally and externally to be water
ght and thermally stable. Each brew tank has its own temperature probe and element which allows the us-
er to set dierent temperatures on each group, as well as operate without a group if a serious service issue
arises. Aached to each group is a 3-way brew valve which controls the ow of water from the group head
to the brew chamber.
Brew Tank Drain Tube: Each group head is ed with a brass ng with a copper seal. The ng and seal
can be removed and temporarily replaced with a short length of tube in order to drain the brew group.
Heang Element: A 2-leg Incoloy and stainless steel heang element which provides the heat for the steam
boiler. It is controlled based on readings from the temperature probe and also protected by the thermal
overload switches, and will be shut o in the case of over-heang or low water levels.
Low Level Probe: Detects when the water in the steam tank is very close to the element. The controller
board immediately cuts power to the heang elements, registers an “STLW00” error on the display (2nd Gen
only) and begins an audible alarm to alert the operator to the problem.
Steam Actuator Rod: This rod is pushed in when the steam handle is acvated. The rod opens the internal
seal, releasing steam through the valve.
Steam Gauge: Displays the pressure in the steam tank. The gauge reads between 0 and 4 bar (0-60 psi).
Standard operang pressure is about 1.3 to 1.4 bar at 250° F.
Steam Shut-o Valve: Shuts o steam to the steam valve for safety during eld repairs.
Steam Tube: Delivers steam from the steam tank to the steam valve to heat and foam milk.
Steam Tank Thermal Overload Switch: Cuts power to the element if the temperature exceeds 280° F. Must
be manually reset if triggered.
Temperature Probes: Send thermal data to the controller board to regulate the temperature within the
steam tank.
High level probe: Detects whether the desired water level has been reached. Water level is adjustable by
rotang the enre probe to raise the p out of the water. The tank will then ll to the new set height.
