ADJUSTING MIX RATIOS
The dispenser comes with the Mix Ratios preset to 35:1. The Left and Right ratios can be set for any ratios
between 20:1 and 100:1, (refer the concentrate package or the supplier for the recommended ratio). Once the
recommended ratio has been entered, the Ratios can be adjusted to suit local taste preferences (i.e. lighter or
darker).
Procedure for Adjusting the Mix Ratio to Taste:
1) Set the left and right dispense ratios to the recommended ratios for the concentrate to be used - refer to
“PROGRAMMING THE DISPENSER” section in this manual.
2) Load the concentrate in the cabinet – refer to “LOADING THE CONCENTRATE” section in this manual.
3) Allow the dispenser to fill with water and heat up to the Ready temp – refer to “INITIAL FILL AND HEAT”
section in this manual.
4) Prime both pumps – refer to “PRIMING THE CONCENTRATE LINES” section in this manual.
5) Dispense Product (left and right) for approx. 30 sec and discard. This will finish priming the lines and allow
the pumps time to adjust to the target RPM.
6) Dispense one full cup of coffee (8 oz minimum) from both sides and evaluate.
a) If the coffee is too weak – Decrease the Mix Ratio slightly.
b) If the coffee is too strong – Increase the Mix Ratio slightly.
7) Repeat steps 5 and 6 until the desired taste profile is achieved
Note: Bunn does not recommend adjusting the Mix Ratio more than 20% from the recommended ratio. Contact
your product supplier or service agent, if more than a 20 % adjustment is indicated, as there may be an error
with the set up of the dispenser.
