Replacement Procedure

 

PurgeX seals should be carefully replaced in a clean environment.  Remove the current seals from the unit.  Wash the remaining components with mineral spirits and allow them to dry completely.  Apply a light coat of oil to the new seals before assembling.  Step by step assembly instructions can be downloaded using the link on this page.

 

 

Note: If the evacuation valve (A7440-1) is removed from the assembly at any time, it must be replaced with a new evacuation valve or the warranty is void.
