SPRAY ARM BY-PASS ADJUSTMENT (ALL Urns ): Adjustable bypass allows proper brew extraction even with variations
caused by soft or treated water. If bypass requires adjustment to correct for local water conditions, proceed as follows:
Position spray head over center of coffee liner and press BREW switch. Turn by-pass adjustment screw clockwise to
decrease by-pass flow (for stronger coffee) or counter-clockwise to increase by-pass flow (for weaker coffee).
At end of brewing cycle, note volume of water in coffee liner. Readjust timer if necessary to obtain the correct volume of
water.
BY-PASS ADJUSTMENT
THERMOSTAT ADJUSTMENT: To adjust temperature of water in urn jacket 197°-203°F (92-95°C), turn thermostat knob
to 10 (maximum clockwise position). Pull off knob and insert a small screwdriver into adjusting screw in center of shaft
when temperature on dial thermometer approaches the "W" in the word BREW. Slowly rotate screw clockwise until
thermostat pilot light goes out. Turning screw clockwise lowers temperature and turning counter-clockwise raises it. Apply
a sealer (glyptol or fingernail polish) to screw after adjustment has been made.

SPRAY ARM ASSEMBLY: The new improved spray head system was designed to facilitate easier cleaning and
maintenance. The swivel valve has a larger flow opening and the spray head cap is equipped with a stainless steel disc,
used to control the flow of water.
When ordering replacement parts, be sure to order the correct disc and spray cap for each urn, as shown in Illustration.
To prevent lime buildup, especially in hard water areas, remove and clean spray head cap and spray head disc frequently. To
clean swivel valve loosen nut and remove spray arm assembly from urn. Remove sediment by inserting a pipe cleaner
through small hole in valve. If maximum setting of timer fails to deliver enough water, check water pump.
