7. Start by disassembling the diaphragm
assemblies. Remove the air chambers (1)
from the membrane frames.
8. Now loosen the Phillips screws (2)
(positioned in center of rubber membrane),
on either end of magnet assembly.
NOTE: If this repair is felt to be
too challenging or tools are not
available to carry out these steps,
please take the unit back to the
Authorized Dealer or place of
purchase to request assistance.
9. Before removing rubber membranes and membrane
frames from either end of magnet assembly, make sure
to remove the plastic support discs (3).
10. Release the rubber membrane (4) from the membrane
frame by applying light pressure to the edge of the
membrane to push it out of the groove.
11. Insert the new membranes on both membrane frames.
12. Ensure that the rubber membranes are positioned in
the recesses of the membrane frames and are correctly
seated in the groove.
13. Fit the rubber membranes and membrane frames back
onto the magnet assembly. Next reinstall the support
disk (tapered side against rubber membrane) on both
sides of magnet. Before tightening the Phillips screw in
the center on each rubber membrane, make sure that
the position of both frames lines up with indentation on
back of frame, that slightly mocks contour of magnet.
This indentation is designed to prevent the frame from
hitting the magnet during operation.
14. Begin reassembling remaining components in the
reverse manner.
15. Note that the power cable should fit snugly back into
the recesses on the edge of the metal motor casing as
well as the outside plastic housing. Make sure that the
cable glands on power cable are lined up in the correct
position to ensure the cable won’t be pinched or kinked.
16. Complete the operation by fastening all the screws
back into their original positions. Take care not to cross
thread or strip out the heads on the screws.
NOTE: If you are replacing the rubber
membranes only, please proceed with the
following steps!
