8.6.2 Cleaning the pump head
1. Isolate the pump from the electrical supply.
2. Use lifting hole (D) to move the cover. Remove
the cover (B) by loosening the retaining bolts
(A).
3. Check the sealing ring (C) and replace it if
necessary.
4. Rinse the pumphead with clean water and
remove all residues. Make sure that no rinsing
water remains in the pumphead.
WARNING
Never remove the cover when the pump
hose is in the pumphead.
The compression forces on the pump hose
are partially compensated by the cover. By
removing the cover with the hose installed,
subsequent damage can occur.
