Proper Placement of Brewer and Urn
Placement of the TDO-4 Urns must be accessible for both the Drive-Thru employees and walk-up
customers. Using the store layout diagrams identify the layout you are currently in and locate the
preferred location for the tea brewer and urn(s). Remember that when selecting the brewer placement you must consider the electrical and plumbing requirements. Orange outlets are not to be used.
If power cannot be located at any of the placement locations call in a Utility Construction Delay to
BUNNserve immediately.

When the placement of the equipment has been decided remove the brewer from the box and place
in the preferred location. With the brewer out of the box, remove any packing material and the
shipping cap from the water inlet fitting at the back of the brewer. Remove all the parts from the
parts box before beginning the installation.
Plumbing Installation
Process 1: Locate the non-carbonated water line
Locate the non-carbonated water line from the filtration system in the
back room of the kitchen. This is usually found over the Bag in the Box
Rack. All locations should have a previously installed water filtration
system. Be sure to always use the non carbonated line after the carbon
filter. This line will split off and enter the carbonator, so be sure to trace
the correctly numbered water line.
Note: If the non-carbonated filtered water line cannot be identified in the back of the kitchen, locate
the line underneath of the drive-thru table.
Process 2: Check the flow rate of the water line
Step 1: Locate the 4 quart container at the store.
Step 2: Place the water line into the container.
Step 3: Get your timer or watch ready to time the water flow for 30 seconds.
Step 4: Start your timer and turn on the water at the same time. Time the
water for 30 seconds then turn off the water.
Step 5: Measure the water volume in the container.
Note: Y
ou must have a minimum of 3 quarts (3/4 gallon) in the container. If you do not have the minimum requirement, find an alternative water source.
Process 3: Hooking up the water line
Step 1: Flush the entire water line.
Step 2: Securely attach the line to the bulkhead fitting at the rear of the
brewer.
Step 3: Turn on the water supply and look for leaks.
Electrical Installation
Step 1: Remove the top cover form the brewer.
Step 2: Verify that the control thermostat knob is in the off position (fully counterclockwise), and place the top lid back onto the brewer.
Step 3: Connect the brewer to the power source. The unit requires 120 volt plus
grounded service with a dedicated 15 amp circuit. This needs to be within 6 feet of the brewer.
Note: O
range outlets are not to be used. If power cannot be located at any of the
placement locations call in a Utility Construction Delay to BUNNserve
immediately. Notify the store manager of the need to install at a later date to
be determined.
Setup
Step 1: Place an empty urn on the brewer base. Be prepared to empty the urn during
these initial steps.
Step 2: Place the on/off switch in the on position, and momentarily press the start
switch. Water will flow into the tank and urn at the same time. When the
first cycle stops, empty the urn and press the start switch again. During the
second cycle, the tank will fill to its capacity and the excess water will flow
from the sprayhead into the urn. Empty the urn when this second cycle is
complete.
Step 3: Unplug the brewer from the power source.
Step 4: Remove the top lid and rotate the control thermostat knob fully clockwise to the
on position and replace the top lid.
Step 5: Plug in the brewer and allow for the water in the tank to heat to the correct
brewing temperature (approximately 20 minutes) before brewing another batch.
Note: S ome water will drip from the sprayhead during this time. This is due to the
expansion of water inside the tank, and will occur after the initial heat up.
Step 6: Begin another brew cycle and measure the total water volume from the dispenser.
Step 7: The total water volume should be 399 ounces.
Note: T
he hot water concentrate should be between 90 and 96 ounces. The cold water dilution should be
between 303 and 309 ounces. If not, adjust the timer as required. For information on how to adjust the
timer refer to the Adjusting Brew Volumes section of the instruction set.
Step 8: Empty the dispenser and allow water in the tank to heat to the proper temperature.
Step 9: The brewer is now ready to be calibrated with finished Brewed Tea product.

Verify the Correct Volume of Brewed Tea
Step 1: Place a 3 ounce tea bag, seam side down, into the brew basket.
Step 2: Slide the brew basket into the guide rails on the brewer.
Step 3: Begin a brew cycle and prepare to measure the brewed tea with the
measuring containers.
Step 4: Ensure the finished brewed batch is between the marks identified on the
TDO-4 Urn. The target volume is 384 ounces (3 gallons).
Note: If the volumes are not at the desired amount adjust the timer as needed.
For information on how to adjust the timer referto the Adjusting Brew Volumes section of this instruction set. If adjust is needed make sure that the
set/lock switch on the timer board is left in the lock position.
Step 5: Place the stainless steel drip tray in front of the brewer.
Placement of Additional TDO-4 Urn
Place the urn(s) in the proper placement location(s) as identified from the
layout location(s) and align the drip tray properly. Make sure to place the lid
and clamp on the top of the unit.

Adjusting Brew Volumes
CAUTION: Disconnect the power source from the brewer prior to the removal of any panel for the
replacement or adjustment of any component.
Note: Prior to setting or modifying batch sizes, check that the brewer is connected to water supply,
the tank is properly filled, and a funnel and server are in place.
Step 1: Modifying batch sizes. To modify a batch volume, first check that the SET/LOCK switch is
in the “SET” position on the circuit board.
To increase a batch size. Press and hold the START or BREW switch until three clicks are heard.
Release the switch (Failure to release the switch within two seconds after the third click causes the
volume setting to be aborted and previous volume setting will remain in memory) and press it again
one or more times. Each time the switch is pressed, two seconds are added to the brew time period.
Allow the brew cycle to finish in order to verify that the desired volume has been achieved.
To decrease a batch size. Press and release the START or BREW switch once for every two-second interval to be removed from the total brew time period; then immediately press and hold down
the START or BREW switch until three clicks are heard. Release the switch. (Failure to release the
switch within two seconds after the third click causes the volume setting to be aborted and previous volume setting will remain in memory). Allow the brew cycle to finish in order to verify that the
desired volume has been achieved.
Step 2: Setting batch sizes. To set a batch volume, first check that the SET/LOCK switch is in the
“SET” position on the circuit board. Press and hold the START or BREW switch until three distinct
clicks are heard, and then release the switch. (Failure to release the switch within two seconds after
the third click causes the volume setting to be aborted and previous volume setting will remain in
memory). View the level of the liquid being dispensed. When the desired level is reached, turn the
ON/OFF (UNSWEET/OFF/SWEET) switch to “OFF”. The brewer remembers this volume and will
continue to brew batches of this size until the volume setting procedure is repeated.
Note: When brewing tea, batch volumes will decrease due to absorption by the tea leaves.
Step 3: Setting programming disable feature. If it becomes necessary to prevent anyone from changing brew times once programmed, you can set the SET/LOCK switch to the “LOCK” position. This
will prevent any programming to be done until switch is once again placed in the “SET” position.
