disconnect the silicone tubes "H" and "G".
To remove the pump "A" use the 12 mm

such way that it does not rotate, by means of
15 mm spanner "7" unscrew the connector "D"
with its joint "E1"; to remove the pump "C"
proceed following the above description with
the only difference that you have to unscrew
the tube union "F" by hand with its joint "F1".
Caution: to mount again the
connectors "D" - "F" it is important
to apply on it a clamping torque of
MAX 2,5 N x mt so as not to damage
them.
They have to be tightened until the ring nut
hits the tube and not more. If is possible
