V-ring Replacement
!
WARNING
Ensure the tank is at atmospheric pressure
before opening. A pressure build-up inside the
tank can cause a spray to be emitted from the
vent valve if opened under pressure.
1. Remove the pallet assembly. Grasp the pressure seal
firmly by the lip and pull out.
2.
Insert the new seal. Use a finger, wrench or other
smooth edge to apply a firm pressure while sliding
around the entire seal several times. When the seal is
completely seated, there will be no humps or waves in
the lip.
