Installing the Pump Heads
Note:
When installing new pump heads, ensure that you install two pumps of
the same flow rate (that is, either two F10 pumps or two F100 pumps). Do not
mix the pump heads.
To install the pump heads
1.
If you removed the inlet and outlet check valves from the pump head, insert the
valves and firmly tighten each one.
For more information about replacing the check valves, see
pump head check valves on page
2.
Locate the small washer and O-ring that you stored.
3.
Slide the small washer onto the piston and push it back as far as it will go.
4.
If necessary, insert the O-ring into the groove on the wash housing.
5.
Verify that the pump head seal is securely fitted in each pump head.
