OPERATION (continued)

WATER HEATER

Separate coffee brew water and faucet water 

heater systems are identical.  Each heating 

element is protected from over-temperature 

by a manual reset hi-limit safety thermostat.
Water temperature is sensed by a 

thermobulb inserted into each water 

tank.  This temperature signal is fed to the           

corresponding thermostat, which controls   

line power to that tank’s heating element.
The temperature setpoint is adjustable at the 

thermostat.

WATER FLOW

AUTOMATIC COFFEE BREW

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.
A second brew cannot be initiated until 

delay time (set by DELAY section of timer) is    

completed

HOT WATER FAUCET

Water level in the faucet water tank is sensed 

by an electronic probe.  When no water is 

sensed at the probe, the controller energizes 

the faucet side of the fill solenoid.

NOTE:

If water is not detected at water level probe 

for two minutes, unit will shut down.

NOTE:

The faucet is gravity fed from a tap in the 

faucet water tank.
