Replacing the Riser Tube O-rings

1. Bypass the unit, depressurize, and disconnect the black C-clips from the bypass assembly. 

2. Remove the Valve Head by unclipping the retaining clamps from the tank neck. 

3. Check for any damage to the resin tank neck. Replace the three Distributor O-rings between the valve head and resin tank.
