Important: If you hear a hissing sound and an error message appears, the silicone seals are not properly aligned with the filter chip, which will result in leaking. Before continuing, check the chip and the silicone seals and reposition them if necessary, then try again. If this problem persists, please contact support@formulatrix.com for assistance. For more information, see Fixing Silicone Seals and Chip Leakage.
The cycle will pause and switch to Manual Control when the volume has reached the threshold (set from More Options) above your final volume.
