Assembly:

1.Inspect and clean the tank, ring threads and O-ring groove. Replace damaged parts as necessary.

3.Ensure that the air bleed assembly on top of the mod- ule is clean and properly mounted.

NOTICE: Lubricate O-ring only with the silicone grease provided or equivalent, as other lubricants may cause the ring to swell. DO NOT lubricate Posi-Lok™ ring or threads on lower tank shell as this may collect grit and make removal difficult.

O-ring is clean and not twisted.

5.Push the upper tank shell into the lower tank shell to compress the O-ring.

6.Place the Posi-Lok™ ring squarely over the tank shell threads and rotate COUNTERCLOCKWISE until the ring falls into the slots; then rotate CLOCKWISE until securely latched.
