OPERATION (continued)

WATER HEATER

Water temperature is sensed by an electronic water

temperature probe inserted into the water tank.

This temperature signal is fed to the controller.

The setpoint temperature is adjustable. The

controller sends a command signal to the power

board based upon a comparison between the

setpoint temperature and actual temperature.

See page 15.

The power board energizes the heating elements

based on the command signal from the controller.

Excessive temperature will trip the hi-limit safety

switch. The hi-limit will automatically reset when

the brewer cools.

WATER FLOW

POUR-OVER FEATURE

Pouring any amount of water into the pour-over

opening and into the basin pan forces an identical

amount of heated water out of the tank and through

the spray head.

AUTOMATIC OPERATION

Pressing the BREW key energizes the solenoid

valve, allowing water from an external water supply

to flow into the water tank. The incoming water

forces heated water out of the tank to perform the

brew.

The solenoid uses a flow control device so that

flow is consistent between 20 p.s.i. and 90 p.s.i.

The length of time the solenoid is open is controlled

by the time setting of the controller. See page 18.

After the solenoid closes, water will continue to flow

to the brew chamber until

the water level in the tank falls below the brew

pickup, breaking the siphon.

HOT WATER FAUCET

The faucet water coil is submerged in the 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
