AfiWash Installation manual P/N 9040646.
This section contains the following parts:
 Wash Controller Principles of Operation (below)
 Wash Controller Configuration (page 70)
Wash Controller Principles of Operation
In milking mode, the AfiFree Body allows milk to flow through it freely. In cleaning
mode, cleaning fluids must completely fill the AfiFree Body to enable thorough
cleaning.
In cleaning mode, during system wash, cleaning liquid is supplied by the parlor wash
system. The AfiFree Wash Controller alternately turns the Wash Control Valve(s) on
and off.
The Wash Control Valve opens and closes the washing diaphragm of each AfiFree
Body connected to it, allowing the AfiFree Body to repeatedly fill up with washing
liquid and then to empty.
One Wash Controller controls one or two Wash Control Valves, opening and closing
both Wash Control Valves simultaneously.
One Wash Control Valve controls up to 20 AfiFree155i bodies (see Figure 37).
Figure 37: AfiFree Cleaning System
During the system wash, the Wash Controller opens and closes the Wash Control
Valve(s) according to a preset cycle, until the system wash is complete. The cycle is
set, after parlor installation, according to the Wash Controller Configuration
procedure, below.
