Operation of the Automatic Twin
Coffee Urn
To brew coffee, turn thermostat dial to the BREW
position. Observe dial thermometer on front of the urn.
When brewing temperature is at the high end of brew
zone on dial, the urn is ready to brew coffee.
Place paper filter or muslin leecher bag in brew
basket. Place desired amount of coffee in filter (use urn
grind coffee in 3-gallon urn and regular grind in larger
urns), replace cover, and place brew basket in position
over coffee liner. When using muslin bag, be sure bag
is soaked with cold water before using, and, if a new
bag, be sure to wash out all sizing with warm water.
Swing spray arm from the PARK position over brew
basket and center spray nozzle over brew basket. Push
timer knob. After the timer has completed its cycle, the
orange brewing light will go out, showing that the proper
amount of water has been sprayed. Within 3 minutes
the brew basket with spent coffee grounds should be
removed from urn. To do so, swing spray arm back to
center PARK position. The spray arm should always be
parked in this center position so expansion drippage will
go back into tank. Do not leave the brew basket in liner
over 5 minutes, if possible. Remove cover and brew
basket and then always replace cover over coffee liner.
Rinse out muslin leecher bag and store in cold water
until ready to use.
Keep the thermostat dial at the HOLD position
during all standby periods so that the urn is ready to brew
coffee at any time, with no waiting.
Merely turn
thermostat to the BREW position so the pilot light lights
up during brewing.
During shutoff periods, turn
thermostat to OFF. After all night or weekend shutoff,
a minimum of at least 55 minutes is required to obtain
the proper brewing temperature. On twin models, water
for tea may be drawn from center faucet. Manual refill
is required unless equipped with auto refill.
Care and Cleaning of a Coffee Urn
The procedures used in caring for and cleaning a
coffee urn are as follows:
1. Always rinse urn immediately after each use.
2. Add small quantity of hot water, brush sides, and
rinse with hot water until it runs clean. Urn is now ready
for next batch.
3. At end of each day clean and brush urn several
times and then rinse thoroughly with hot water.
4-26
4. Remove cleanout cap at end of coffee faucet (or
take apart faucets that have no caps) and scrub pipe
leading to center of urn. Clean urn gauge glass with
brush and urn cleaner. Rinse thoroughly.
5. Scrub the faucet and then rinse it thoroughly
with hot water.
6. Place a gallon or more of fresh water in urn until
next use.
7. Remove cover and clean. Replace cover and
leave partly open.
8. Always remember to empty and rinse the urn
with hot water before using again.
NOTE: On automatic urns, use any of the BREW,
START, STOP, or RINSE switches to spray scalding hot
water into the liner for cleaning and rinsing. On
Pour-over urns, draw hot water directly from urn. Make
sure urn water tank is kept nearly full and the heat is on.
Destaining a Coffee Urn
The procedures for destaining coffee urns are as
follows:
1. Fill urn with destaining compound solution. Fill
urn with water 175°F. Add destaining compound (stain
remover, tableware, in this ratio: 2 tablespoons per 5
gallons of water or as directed by manufacturer).
2. Draw off mixture and repour. Open spigot and
draw off 1 gallon; thoroughly remix to allow mixture to
come into faucet. Allow solution to stand for 1 hour at
170°F to 180°F. Stir occasionally.
3. Scrub urn liner and gauge glass. Use
long-handled brush to loosen scales.
4. Clean faucet. Take faucet valve apart and clean
all components. Soak in hot water until reassembled.
5. Rinse and reassemble faucet valve. Rinse urn
liner three or four times carefully with hot water. Repeat
until all traces of compound are removed.
