  • Page 6 Acro has 2 air intake ports and 1 exhaust port. The intakes are on the front, lower left side of the machine, and on the right (vessel) side. The exhaust is on the left (non vessel) side. Each of these ports cannot be blocked, and must allow adequate airflow.
  • Page 7 We use a tube with a 1/2" ID x 3/4" OD. Preferably hook Acro up to a faucet with the ability to mix hot and cold water. In the winter, your cold water might be below desired steeping temperatures, and Acro cannot heat water.
