Sequence of Operations
- Close all valves.
- Liquor tank is filled with cold water (or hot water preheated in kettle). Input desired strike temperature and activate liquor heater.
- Mash tun is filled with approximately two gallons of cold water (or hot water preheated in kettle). Input desired initial mash strike temperature and activate mash heater (heater will not operate until pump starts). Consider using a larger liquor tank to eliminate this step.
- Open Mash to Pump Valve and Mash Heater Inlet. Set pump to low speed and turn on, and adjust pump as needed.
- When mash tun and liquor tank reaches setpoint, dough in grain.
- Close Mash to Pump Valve and open Liquor Tank Isolation Valve to add desired final water quantity (adjust pump speed if needed).
- Open Mash to Pump Valve and close Liquor Tank Isolation Valve to circulate mash (adjust pump speed if needed).
- Input desired mash temperatures and activate mash heater (heater will not operate until pump starts) and start timer. If desired lautering temperature is different than strike temperature, change setpoint.
- Mash is automatically controlled at each temperature for the correct duration of time, and transitioned to the next temperature until complete.
- After conversion, deactivate mash and liquor heater. Close Mash to Pump Valve, open Liquor Tank Isolation Valve, and partially open Mash to Kettle Valve (adjust pump speed and Mash to Kettle Valve as needed). Turn off pump when complete.
- Boil wort. Discard spent grains, and open all valves (except Kettle Isolation Valve) and remove drain plug to drain residue. Clean applicable components if desired. Close all valves and replace drain plug.
- Upon completion, place wort heat exchanger outlet in wort, open Kettle Isolation Valve and Heat Exchanger Inlet Valve, and turn pump on low and circulate to sterilize. Enable wort heat exchanger to subcool wort if wort heat exchanger is inadequate (not that displayed “Mash Temperature” is really pump discharge temperature and now measures kettle temperature). Transfer heat exchanger outlet to fermentor and adjust pump as needed to ensure proper discharge temperature.
- Add water to system, add bleach (verify if this is not a good idea), heat up, circulate system, and drain.
