HYDRAULIC SYSTEM
MAjOR COMPONENTS OF THE WATER INLET SYSTEM (CONT.)
Steam Inlet Check Valve:
See Brew tank check valve description. (Page 22).
Steam Inlet Water Control Valve:
When the
upper level probe (Page 25)
detects an absence of water, the control board will
send a signal to open this valve and allow water into the steam tank. 1st generation machines have a
manual fill switch to open this valve at the operator’s discretion in addition to the autofill system.
Steam Tank Inlet Fill Line:
(
Combined with Brew Inlet on single inlet machines)
)
This is the incoming 3/8” steel braided line which supplies the steam tank with water. May be
labelled with a pink tag on Hydras.
Vacuum Breaker
:
Prevents steam tank pressure from dropping below atmospheric pressure. As the tank heats,
the pressure from the steam pushes an internal rod and o-ring up, sealing the vacuum breaker. When
the tank cools below the boiling point, steam will condense and shrink in volume potentially pulling a
vacuum in the steam tank. At this point, the internal rod and seal will drop down and allow air into the
tank to replace the cooling steam, preventing a vacuum.
