A and C phases are a function of pulsator style/brand, length of pulsation hose, and liner/shell design and cannot be changed by rate and ratio.

*As with any liner change, it’s critical to observe cow comfort levels and check for discoloration of the teats. Transition to a new liner my be immediate but could take several days. Vacuum and pulsation changes should only be made after cows transition completely.
