May 2009 AfiFree Terminal 155i Installation Manual 29
Wash Controller Positioning
Position the Wash Controller as follows:
On a wall or other location where its LEDs can be seen clearly from the parlor
floor
Shaded from direct sunlight (all hours of the day) and protected from water (e.g.,
rain and leaking pipes)
Clearance of at least 19 cm (7½ ‖) above the Controller , so that the lid can be
opened and kept open above the unit
Safely accessible for wiring and maintenance
Out of the reach of livestock
In addition to the above general guidelines, the Wash Controller location depends
on how it is activated:
▪ If the Controller is manually activated via the manual start button, it must be
mounted within easy reach of the operator, so that the button is easily
accessible
▪ If the Controller is activated remotely or automatically, it can be mounted
higher up. However, the Controller remote activation button must be mounted
within easy reach of the operator.
Wash Control Valve Positioning
Position each Wash Control Valve as follows:
Connected to the main vacuum line
So that it is convenient to install the AfiFree155i diaphragm line between it and
the AfiFree155i Bodies
Positioning Optional External Start Buttons
In installations with an External Start Button, position it according to the following
guidelines:
The button facing the milking pit
Within arm’s reach of the milking operator
Consistently throughout the parlor, so that each AfiFree unit is clearly associated
with its control button. For example, if you install a button on the right side of
the first AfiFree unit, maintain this layout in all other stalls.
