Thermostat
The thermostat is factory set so that the knob on the BREW setting holds the urn at
brewing temperature toward the HI end of brew zone on the thermometer dial. Then, if
turned back to HOLD position, the thermostat should cycle on and off and hold at the LO
end of the BREW zone on the thermometer.

Push Button Timer For Spray Over Control
The function of the timer is to start the pump and run it for a preset period of time and upon
lapse of this time, to stop the pump, thereby completing the spray over cycle.
This urn is equipped with an electric reset timer. Pushing in the START button will start the
flow of water. The timer will complete the time cycle for which it has been programmed and
on completion, the flow will be stopped and the timer will reset itself, ready for the next
brewing cycle.
If electric power is cut off anywhere in the service coming to the urn during the timer
operating cycle, the timer will reset. When the power is restored, the timer must be
restarted by pushing the START button.
Spray Rinse Of Liner
To rinse the liner after brewing coffee, swing the spray arm over the desired liner and push
START button. Allow hot water to spray from the spray arm for approximately 30 to 60
seconds and then push STOP button and drain the liner.
If the water temperature is below the HI end of the BREW zone on the thermometer dial
with the knob on BREW setting, remove the knob by pulling it straight outward. Using a
small screwdriver, insert in the hole in the center of the shaft, turn slotted screw counter-
clockwise until the red pilot light goes on. Check to see that water in the urn holds at the
HI end of the BREW zone on the thermometer and does not
boil.
If the water boils with the thermostat knob set at the BREW position, remove the knob by
pulling it straight outward. Using a small screwdriver, insert into the hole in the center of
the shaft, turn slotted screw clockwise until the red pilot light goes out. Hold shaft so it
does not turn while adjusting screw. Add cold water and check that the heat comes back
on (pilot light glows), and that the thermostat cycles at temperature at HI end of the
BREW zone on thermometer dial.
If the thermostat will not cycle, replace the entire control.
