1 Pump module
2 Pressure reservoir housing cover
3 Pressure reservoir
4 O-ring
5 Air filling valve
We would like to point out that in the event of a defective pressure reservoir (3), e.g. if this has burst due to the affect of frost or if the cap of the air filling valve (5) can no longer be opened due to corrosion, the complete pump module (1) does not have to be replaced, but only the pressure reservoir (3).
The repair instructions for installation/removal of the pressure reservoir (3) are contained in the WIS.
