1st and 2nd position brew tank fill tubes:
After travelling through the steam boiler, the heat exchangers exit on the left side of the
machine and copper tube (these were stainless steel until serial number 352) deliver the
pre-heated water to the brew tanks.
Brew tank:
Synesso™'s brew tanks are solid stainless steel, welded internally and externally in order to be
leak-proof and thermally stable. Each brew tank has its own isolated system from the water
inlet. This allows the user to set different temperatures on each group, as well as function
without a group in the system if something has gone wrong with a group. There is a 3-way
brew valve which controls the flow of water to the group head.
Brew tank drain tube:
Each group head is fitted with a drain tube to easily drain the tank. In order to drain a brew
group, remove the pressure from the brew groups by turning off the water, cycling through the
control panel to the Temperature Display screen on menu level 2. Turn the Brew Valve
setting to ON which will allow a small amount of water to run out of the groups. Once the water
stops, select NORMAL on the Brew Valve control line. Remove the 1/2" plug fitting on the end
of the drain and attach a 3/8" rubber line to drain the water into the drain pan. Set the Brew
valve control back to ON to completely drain the tank.
Heating element:
A 2-leg incoloy and stainless steel heating element which provides the heat for the steam
boiler. It is controlled by the thermal probes and will be shut off in the case of over-heating
or low water levels.
