    • Open the steam tap(s) and dispense until steam ceases. This will ensure that no steam pressure is built in the boiler.

    • Leave one or both steam wands in the dispensing position, as this will aid the speed of draining.

  2. Be sure that the steam boiler is cooled and depressurized before proceeding! Using the 5mm hex wrench,  remove the sight glass plug from sight glass. Use the 13mm open end wrench to keep the base of the fitting from rotating, as shown.
