Installing Vacuum & Air Lines
1.
Use 50 mm diameter PVC pipes for both lines. Three (3) mm wall thickness
is recommended.
2. Place vacuum and the clean-air lines as close as possible to the main milk-
line. Flexible tubes connect milk meter solenoid ports (Vacuum and
exhaust) to their relevant lines, below the milk meters (illustrated in green
and red in Figure 8 above). Length of flexible tubes should not exceed 50
centimeters (20").
3. Secure the lines to a wall, or to any common bracket, with its fitted clamps.
Prevent pipes from sagging.
4. Install a drain valve at the lower end of each pipe
5. Secure lines with slopes:
>
Secure the solenoid vacuum line with a downward slope of 1.5 –2°,
towards the drain valve (detail B in following drawing).
>
Secure the clean air line with a downward slope of 1.5 – 2°,
towards the ½” ball valve (detail C).
6. Install joints, ends, and vertical sections and as follows:
o
Solenoid vacuum line:
i. At the lower end of the solenoid vacuum
line, install a T joint. At the bottom
opening of the T joint, install a ½” drain
valve as shown in detail B.
ii. From the upper opening of the T joint, extend the
solenoid vacuum line vertically, upwards.
iii. Connect the solenoid vacuum line to the main vacuum
supply
line high up in the parlor, as close as possible to
the balance tank. DO NOT connect the solenoid vacuum
line to the pulsator vacuum line .
iv. At the top, at the connection to the main
vacuum line, make a PVC pipe bow shape,
as shown in detail A.
