Cleaning/Replacing The Vacuum Generator

4. Check for leaks by covering all the holes in the applicator pad with a piece
of paper. If there is a leak, the vacuum will not retain the paper on
underside of the applicator. Sealing compound may be used to isolate
leaks, but must dry thoroughly before the applicator may be used.
Cleaning/Replacing The Vacuum Generator
Air flow through the vacuum generator creates the vacuum for the applicator
pad, allowing the label to be held in place. If the label is not retained on the
pad and the pad has already been inspected for leaks, then the vacuum
generator should be cleaned as follows.
1. Locate the vacuum generator inside the electrical enclosure, on the
applicator side of the SLPA (see Figure 32). The vacuum generator
housing will mark the pressure connection with a P and the vacuum
connection with a V. Label the respective tubes before disconnecting
them, to ensure proper reassembly.
NOTE: The vacuum generator should develop a minimum of 20 inches hg
with the hose to tamp pad blocked.

2. Remove the two air lines attached to the vacuum generator by pushing in
on the tube fitting (red collar) to release tension on the flexible tubing.
Hold the tube fitting down while pulling the tube free.
