ADJUSTMENT & OPTIONAL SETTINGS
SETTING THE MIX RATIO/BRIX
Ratio Cup Method
1. Adjust the water flow as described in
Water Flow Testing and Adjustment.
2. Remove the dispense nozzle from the appropriate dispense position.
3. Assemble, lubricate, and install the Flow Separator Assembly (BUNN-O-MATIC part number 32629.0000) into
the dispense nozzle receptacle (dispense valve,) making sure to point the arrow on the separator body away
from the dispenser.
4. Place an empty container under the Flow Separator Assembly.
5. Dispensers with Press and Hold Feature:
Press and hold the “Product Dispense Switch” Fig 5, until water and concentrate begin flowing freely from
the Flow Separator Assembly nozzles.
Dispensers with Portion Control Feature:
Press and hold the “+/Stop Switch” Fig 6, until water and concentrate begin flowing freely from the Flow
Separator Assembly nozzles.
6. Place the empty brixing cup (BUNN-O-MATIC part number 33095.0000) under the Flow Separator Assembly
nozzles, small (concentrate) chamber to the left and large (water) chamber to the right.
7. Dispensers with Press and Hold Feature:
Press and hold the “Product Dispense Switch” until concentrate reaches the 1 oz. (black line) mark.
Dispensers with Portion Control Feature:
Press and hold the “+/Stop Switch” until concentrate reaches the 1 oz. (black line) mark.
8. Read the level in the water chamber. This reading directly determines the mix ratio (i.e. If the water level reads
4.0 oz., then the mix ratio is 4 [water] + 1 [concentrate].)
9. Adjust the pump speed (down to increase the ratio, up to decrease the ratio) to achieve the correct mix ratio
as described in
Pump Speed Programming.
10. Remove the Flow Separator Assembly and replace the dispense nozzle assembly into the dispense nozzle
receptacle (dispense valve.)
Temperature Compensated Refractometer Method
1. Adjust the water flow as described in
Water Flow Testing and Adjustment.
2. Place an empty container under the appropriate dispense nozzle.
3. Dispensers with Press and Hold Feature:
Press and hold the “Product Dispense Switch” Fig 5, until water and concentrate begin flowing freely from
the dispense nozzle.
Dispensers with Portion Control Feature:
Press and hold the “+/Stop Switch” Fig 6, until water and concentrate begin flowing freely from the dispense
nozzle.
4. Discard the product caught previously and place the empty container back under the dispense nozzle.
5. Dispensers with Press and Hold Feature:
Press and hold the “Product Dispense Switch” until the cup is filled.
Dispensers with Portion Control Feature:
Press and hold the “+/Stop Switch” until the cup is filled.
6. Stir the contents of the cup, and use the refractometer (according to the manufacturer’s instructions) to check
the brix %.
7. Adjust the pump speed (down to decrease the brix %; up to increase the brix %) to achieve the correct brix
% as described in
Pump Speed Programming.
