Stage 2 : Adjusting the special Manta II diaphragm
If the opening of the diaphragm’s cavity is too large
(over 4 mm), but the diaphragm is not damaged or torn,
you can solve the problem by leaving one ridge
of the diaphragm exposed from the cassette chamber.
This may eradicate any performance-related problems –
cleaner stopping, coverage problems. (13)
Stage 3 : Re-fitting the diaphragm
1. Fit the diaphragm to the inner extension pipe.
If it is a new diaphragm, do not forget to put
the retaining ring in place. (14)
2. Slide the upper part of the inner extension pipe
(end opposite the diaphragm) into the lower part
of the cassette. The diaphragm must fit perfectly
into the lower part of the cassette. (15)
3. Screw the cassette chamber to the cleaner’s outer
extension pipe. Do not over tighten.
4. Reinsert the cassette into the body and tighten
the outer extension pipe / cassette unit,
until it has clicked into place. (16)

PROBLEM SOLVING
To be checked
• Check that your filtration system is working properly
and that the multiport valve is in the filtration position.
• Check whether the filter and the skimmer baskets are
clean.
• Make sure the main drain is fully closed.
• Shut down the other suction lines to increase the flow
into the automatic pool cleaner.
• Check the power of your pump: the minimum flow
necessary is approximately 5m
3
/hour.
• Check whether the diaphragm of the automatic pool
cleaner is obstructed by debris or is damaged.
CHANGING THE DIAPHRAGM
Stage 1 : Removing the diaphragm
1. Hold the main body of the Manta II and disconnect
the cassette from the body. Remove the cassette from
the body of the Manta II. (9)
2. Whilst holding the outer extension pipe with one
hand, unscrew the cassette chamber completely. (10)
3. Take hold of the diaphragm and remove it
from its cassette. (11)
4. Withdraw the diaphragm from the inner extension
pipe without removing the retaining ring on the
diaphragm. (12)
