WATER HEATER
Water temperature is sensed by a
thermobulb inserted into the water tank. This
temperature signal is fed to the thermostat,
which controls line power to the heating
element.
The setpoint temperature is adjustable at the
thermostat.
The element is protected from over-
temperature by a hi-limit thermostat.
WATER FLOW
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.
AUTOMATIC OPERATION
Pressing BREW button energizes the
solenoid valve, allowing water from an
external water supply to flow into the basin
pan and then into the hot water tank. This
forces an identical amount of hot water out
of the tank and through the spray head into
the brew chamber
The solenoid uses a flow control device so
that flow is consistent between 20 p.s.i. and
90 p.s.i.
Length of time the solenoid is open is
controlled by the timer.
HOT WATER FAUCET (RIGHT SIDE)
The faucet water coil is submerged in the
right side hot water tank, and draws heat
from the brew water. Water going to the
water coil is not controlled by the solenoid
valve.
Hot water is provided at the faucet, at supply
water pressure, any time the faucet shut-off
valve is OPEN.
