If the bleeding screw does not face upwards, you must rotate the pump head. To do so, proceed
as follows:
1. Loosen the hex head bolts and remove them.
2. Loosen the pressure sensor's capillary tubes (see 4.4.3 "Differential pressure sensor handling").
3. Carefully rotate the pump head to the required position without lifting it off the pump hous-
ing.
(If the pump head is firmly attached to the pump housing, loosen the pump head by hitting it
lightly with a rubber mallet.)
4. Replace the hex head bolts and tighten them crosswise.
5. Connect the pressure sensor's capillary tubes.
