5. Carefully remove the pump head from the SP by pulling the head straight off
and away from the SP panel.
6. Place the head on a clean work surface.
7. Hold the shaft of the piston (near the base), tilt the piston slightly, and pull the
piston away from the pump. The piston does not come off as part of the pump
head assembly because it is captured by a magnetic retention system.
To install the new backup seal:
1. Lift the spacer off the pump head.
2. Remove the backup washer from the spacer, using
one of the following methods:
•
With the backup washer facing up, cup the
spacer in your hand and blow clean laboratory
air at the spacer to dislodge the washer.
•
If air is not available, create a removal tool by
using a pair of pliers to sharply bend the end of a
paper clip (see the following photo). Carefully
Lateral motion while disengaging the pump head from the piston may
break the piston.
Un mouvement latéral pendant la séparation de la tête et du piston
peut casser le piston.
Vermeiden Sie Seitwärtsbewegungen, wenn Sie den Pumpenkopf vom
Kolben lösen. Andernfalls kann der Kolben brechen.
