CAUTION – Disconnect the power source from the brewer prior to the removal of any panel for the replacement or adjustment of any component.

NOTE: Check that the brewer is connected to water supply, the tank is properly filled, and a funnel and server are in place, prior to setting or modifying batch sizes.

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. If the brewer has a batch selector switch, position it to the size to be changed.

To increase a batch size, Press and hold the START or BREW switch until three clicks are heard. Release the switch and then 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. Allow the brew cycle to finish in order to verify that the desired volume has been achieved.

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 (this will take approximately ten seconds), and then release the switch. (Failure to re- lease the switch within two seconds from the third click causes the volume setting to be aborted). View the level of the liquid being dispensed. When the desired level is reached, turn the ON/OFF switch to “OFF”. The brewer remembers this volume and will continue to brew batches of this size until

the volume setting procedure is repeated. Empty server(s), turn selector switch to positions that have yet to be set, and repeat batch setting proce- dure until all batch sizes are set.

NOTE: When brewing coffee, batch volumes will decrease due to absorption by the coffee grounds.

The low-profile feature makes it an ideal choice for settings that require efficiency and space optimization without compromising on the quality of the brew.

Another notable member of the series, the TB3Q and TB3Q-LP, feature a quick brew ratio, allowing users to brew up to 3 gallons of coffee in just a few minutes. These models are equipped with easy-to-use controls for simplified operation, making them perfect for staff training and user accessibility.

All models in the TB series include a hot water faucet, allowing users to dispense hot water for tea or other hot beverages quickly. This versatility adds significant value, especially in multi-beverage settings.

Regarding durability, the Bunn TB series is constructed with high-quality materials, ensuring longevity and reliability. The machines also feature internal components that are easy to access for maintenance, thus reducing downtime and improving the overall efficiency of the machine.

In terms of technology, these brewers often incorporate advanced diagnostics to promptly identify service needs or issues. The machines come with a precise brewing temperature control system that ensures each cup is brewed at the optimal temperature for maximum flavor extraction.

Overall, Bunn's TB6Q, TB3-LP, TB6, TB3Q, and TB3Q-LP coffee brewers represent the culmination of advanced brewing technology and practical design for commercial coffee solutions. Their efficiency, quality, and ease of use make them a staple in many establishments, solidifying Bunn's reputation as a leader in the coffee brewing industry.
