Installation

1. **Connecting the ColdBRU to water

**

2. **Connecting the ColdBRU to power

**

Setup

• Calibrate the machine. (Only necessary on initial plug in of machine or if water pressure changes).
• Right after plug in, settings icon will appear, press all three buttons at once.
• if you miss this menu, unplug and try again.

Create your own recipe

Note: the maximum dispense of the ColdBRU is 10.5 Litres/2.75 Gallons (US). To avoid overfilling the ColdBru, we suggest starting with a medium sized brew and adjusting based on your results. If you achieve less than this, you should repeat the brew, grinding finer, or increasing the coffee dose to create a deeper bed.

Suggested starting point for New recipe (medium capacity brew) for ColdBru:

• 800g medium ground coffee.
•  5000ml/1.3 Gallons (US) water.
•  02:00hr Brew Time (this refers to the water delivery time, overall contact and drain time will vary).
•  Initial pulse should be set to 60% total volume, ideally this will create a head of brew water above the coffee bed. Initial pulse value can be increased if necessary.

Prepare ColdBru for brewing

1. Insert metal filter

2. Weigh amount of coffee according to recipe on screen
   Weigh and grind into brew chamber according to recommended grind size

3. Level coffee bed. Do not shake/tap to level as this will force coffee through the filter

4. Tamp coffee bed using provided tamp, flattening the ground coffee
5. Insert brew chamber into machine
6. Ensure container is open and lined up correctly with nozzle of brew chamber

Brewing with ColdBru

Method 1: Create new brew
Note: The Preset Brew option dispenses the desired water volume over 6 separate phases. Each phase consists of a water dispense time and a drain time. The amount of water dispensed in the 1st phase is dictated by the user as a percentage of the entire volume of water. The remaining water dispensed is distributed in equal parts across the remaining 5 phases.

1. Select “Preset” mode.
2. If you want to create a brew different to those saved in memory select “New”.
3. Follow on-screen prompt.

4. Follow on-screen prompt.

5. Follow on-screen prompt.

6. Press +/- to dial in required volume of water for this brew and press “Next” when done.

7. Use the +/- buttons to dial in the % of the total water that will be dispensed in the first pulse.
   For medium brews (800g coffee + 5ltrs of water) we would not recommend going over 60% in case of overflowing. For smaller brews this can be exceeded.

8. Use the +/- buttons to dial in the dispense time.
   Note: This is not the full brew time, brew time may require additional time at the end to ensure all water has filtered through the coffee.

9. Review the brew settings.
   Pressing “Start” will start water dispense.

10. During the dispense phase, the brew can be paused or aborted.

11. After the machine has dispensed the designated amount of water for the first phase, it will allow drain time before moving onto the next phase. This cycle will continue until all 6 phases are complete.

   (through visual confirmation of water in the brew chamber or volume displayed on-screen). Pressing “Stop” will stop the water dispense and start the filter phase timer.

8. Filter time begins. This time represents elapsed time that water has been filtering through the coffee and includes dispense time. When satisfied that sufficient water has filtered through the coffee, press “Start” to commence second water dispense. This cycle continues through a maximum of 12 phases Pressing “Esc“ will give you the option to exit and save the brew if you are satisfied with the results.

Adjust Recipe / Troubleshooting

In presets, go to desired recipe and select ‘Edit’

Coffee concentrate is too weak| •     Try a finer grind (this may increase brew time)

•     Lower inital pulse volume

•     Lengthen dispense time

•     Combination of above

---|---
Coffee concentrate is too strong| •    Use more water

•    Try a coarser grind (this will also decrease brew time)

Brew time is too slow| •     Try a coarser grind

•     Use more water at the start

Not enough coffee concentrate| •    Use more water

•    If strength is acceptable scale up brew ( increase both amount of grinds and amount of water)

•    Try a coarser grind

•    Leave to drain for longer

•    A variation of above points

Too much coffee concentrate| •      If strength is acceptable scale down brew (decrease both water and ground coffee)

•      If strength is too weak add less water

or pull brew early (if yield allows)
