B1. Disassemble the intake and delivery manifolds by removing their fixing elements.

B2. Disassemble the two pump casings by removing the relevant fixing screws.

B3. Remove the external diaphragm locking cap from both the circuits.

B4. Remove the diaphragms from both sides of the pump.

B5. Disassemble the pneumatic exchanger by removing the relevant fixing elements.

B6. Replace the exchanger and the connection shaft with original spare parts having
the same characteristics.

B6.1 For pumps with manual reset on the main casing, the air exchanger must be
placed so that the reference bevel is turned towards the resetting duct.

B7. Reassemble the pump according to the previously described sequence but in
reverse order and tighten the fixing bolts evenly.

Replacement of the coaxial pneumatic exchanger finishes here. You can now
reposition the pump and reconnect it as described in the previous sections.

to avoid incorrect reassembly and subseguent
malfunction of the pump the coaxial pneumatic
exchangers must not be open.
