How to use the Whirlpool Arm

  1. At the end of the boil ensure that the pump and recirculation valve are both switched off.
  2. Connect the Whirlpool Arm to the recirculation pipework so that the other end sits just below the surface of the wort.
  3. Ensure the wort temperature is below 99°C or at your desired whirlpool temperature, then switch on the pump and slowly open the valve to start recirculating the wort.
  4. Add your whirlpool hops and recirculate as per your recipe.
  5. When complete, switch the pump off and carefully remove the whirlpool arm using the black silicone handle (caution: the handle may be hot) and then connect your counterflow wort chiller to complete the chilling process according to your G40 or G70 instructions.
