WARNING
4. Inspect the pressure seal. Remove any debris on
this seal. If there are any tears or cracks in the
seal, replace the pressure seal immediately.
V-ring Replacement
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.
