AfiFree Wash Controller and Wash Control Valve
The parlor washing system cleans the AfiFree155i bodies via the AfiFree Wash
Controller (below) and Wash Control Valve (page 17).
The AfiFree Wash Controller
During milking the AfiFree Body operates with a continuous flow of milk through the
unit. This continuous flow does not allow the AfiFree Body to completely fill. During
the cleaning cycle it is necessary to completely fill the AfiFree Body to ensure that all
milk residues are washed out. The AfiFree Wash Controller (Figure 7) operates the
AfiFree Wash Control Valve, which controls the diaphragm to close and open the
outlet from the AfiFree Body. This allows the AfiFree Body to completely fill and
drain alternately.
Wash Controller setup is explained on page 70.

The AfiFree Wash Control Valve
The Wash Control Valve (Figure 8) opens and closes the Washing Diaphragm
Assembly on up to 20 AfiFree155i Bodies. This causes cleaning liquids to fill the
AfiFree Body and then drain. The cycle is repeated a number of times under the
control of the Wash Controller.
If more than 20 units are installed in the parlor, the parlor cleaning plumbing must be
divided into two or more sub-systems, each with its own Wash Control Valve.
