TROUBLESHOOTING GUIDE
VACUUM SYSTEM INTEGRITY TESTING MANUALLY
POSSIBLE CAUSES FOR VACUUM LEAKS (cont’d)
•
Check the o-rings between the die top and the utility block.
•
Also check the o-ring between the die bottom and the platform.
•
Lubricate the o-rings with o-ring lubricant or petroleum jelly.
•
Replace them if they are damaged or missing.
•
Check the potting compound in the die top wire port.
•
This compound is a black rubber-like epoxy that is used to seal the back of the
plug from moisture and vacuum leaks.
•
If the compound appears cracked isn’t sealed well around the wires it needs to
be removed and replaced.
•
VC999 Packaging Systems recommends “3M DP-270 potting compound”.
Make sure all old compound is removed from the wire port, plug and wires
and these surfaces are cleaned with acetone when replacing potting
compound. This will ensure good adhesion on these surfaces.
•
Check the vacuum valves and the vent valves for internal contamination or damaged
o-rings by removing the side covers on the valves, being careful not to lose or
damage any internal parts.
•
Visually inspect the vacuum hoses for damage and tighten all hose clamps in the
vacuum system.
•
Check 4mm silicon cord between the seal die bottom and the seal frame for damage
or wear.
•
Check the gas flush nozzle gasket for proper installation, damage or excessive wear.
