• Manta II specificdiaphragm adjustment :

If the diaphragm slot opening is too large (more than 4 mm), without nevertheless the diaphragm being deteriorated or broken, you can remedy this by letting a rib of the diaphragm out of the cassette. This can eliminate efficiency problems: clogging of the cleaner, cleaning coverage problems, etc.

• Reassembling the diaphragm:

1. Fix the diaphragm to the inner extension tube. If it is a new diaphragm, don't forget to replace the ring.
2. Slide the top of the inner extension tube (end opposite the diaphragm) into the bottom of the cassette. The diaphragm should fit snugly into the bottom of the cassette.
3. Re-thread the bottom of the cassette onto the outer extension tube of the cleaner, without over-tightening.
4. Reinsert the cassette back into the body and rethread the outer extension tube / cassette assembly until it is snug.
