HYDRAULIC SYSTEM
MAJOR COMPONENTS OF THE WATER INLET SYSTEM (CONT.)
Drain Hose:
Waste water and some grounds go down this tube to the drain. Keep this free of clogs and
maintain a steep vertical path to the floor drain.
Drain Tube (from brew tanks):
This copper manifold allows water from the brew valves to discharge safely down the drain
after shots are completed.
Expansion Valve:
The brew tanks are completely saturated with water. As they heat, the water expands and the
pressure increases. The expansion valve allows this water to release safely into the drain box. The
release point is 12 bar and is adjustable by turning the end of the valve with a wrench clockwise to
increase or counterclockwise to decrease.
Heat Exchanger Tubes:
In order to maintain extremely stable brewing temperatures, Synesso™ incorporates heat
exchanger tubes which run through the steam tank, then supply water to each coffee boiler. The heat
exchangers are precisely designed to aid in the energy efficiency and thermal stability of the brew
system.
Cold Water Valve:
Synesso™ machines have 2 valves which provide water to the americano / tea spout: the hot
and cold water valves. Mixing in cold water allows the user to moderate the temperature at
the spout. Boiling water is not appropriate for all beverages.
Hot Water Valve:
This valve supplies hot water from the steam tank (which is mixed with cold water from the cold
water valve) to the Americano / tea spout.
Mix Valve Adjuster:
This pin valve allows the user to increase or decrease the flow of cold water (from the
cold water valve above) going to the Americano / tea spout. Turning this valve completely clockwise
shuts the cold water off, while turning it counterclockwise allows more cold water in.
Pressure Relief Valve (PRV):
The PRV is a safety release for the steam boiler which opens and releases pressure if the
boiler rises above 3.5 bar (50 psi). The PRV is housed inside the yellow tubing which directs any
releases to the drain box.
Sight Glass:
Connected to the steam tank by two tubes, the sight glass provides a visual representation of
the level of water in the steam tank. It should be 1/2 to 2/3 full during normal operation.
