Mounting the pump head
Note
To prevent the pump head from being positioned the wrong way, it is
provided with different bore hole depths for the fastening bolts, i. e. a
fastening bolt is longer than all others. The bore hole with the greatest
depth must therefore be assigned to the longest bolt. If this is not the
case, the pump will not function perfectly.
1 Mount the pump head on the pump again using the four fastening
screws (14-5). Firmly tighten the screws with the hexagon key
(6.2621.030).
2 Screw connection capillaries (14-1), (14-7) and (14-13) onto the
pump head again.
