Installing the Vacuum Line for the Wash Control
Valve
All references in the following explanation refer to Figure 31 and Table 14.
1. Position the vacuum line (Item 1) above the milk line. Maximum length of the
pipe (Item 2) is 50 cm (19‖).
2. Secure the vacuum line to the wall (or to brackets supporting the milk line) with
pipe clamps (item 8). Place a pipe clamp at each milking station (to prevent the
line from sagging). The vacuum line should be positioned with an angle of 1.5-
2.0 toward the drain valve (Item 6 in Detail D).
3. Drill 11 mm holes in the vacuum line (Detail C), slightly off center from each
AfiFree Body. Ensure that the holes are in a uniform position on the line and
relative to the AfiFree Body.
4. Press the nipple (Item 3) into the 11 mm holes in the vacuum line.
5. While holding the black bushing around the nipple, pull the hard plastic portion
out. This locks the nipple in place and seals the hole.
6. Connect the pipe (Item 2) between the diaphragm on the AfiFree Body and the
nipple on the vacuum pipe.
7. Assemble and mount the vacuum line drain (Items 4, 5, 6, and 7, Detail D) at the
lowest point in the vacuum line, so that when the drain valve (Item 7) is open,
fluids drain from the vacuum line to the floor.
NOTE
Clean the Wash Control Valve’s vacuum line in the same manner, and at the
same time, as the Pulsator vacuum line.
