TROUBLESHOOTING
Unstable Pressure or Vacuum
Problem:
Pressure or vacuum cannot be generated correctly, or set pressure or vacuum does not remain stable.
Solution:
If the problem persists after allowing time for thermodynamic effects to stabilize, this is likely to be caused by the incorrectly positioned or
sealing gaskets. Also check that all adapters and pressure fittings have been tightened sufficiently to eliminate leaks.
Pressure or Vacuum is not Maintained
Problem:
The hand pump appears to leak.
Solution:
(1) Check that the vent valve is completely closed.
(2) Check that the shuttle valve switch is correctly positioned and is not in a "center position" (if a combination model).
(3) Verify that all the connection fittings are firmly tightened and properly sealed.
Pumping Action Appears Sluggish
Problem:
The first lift of the pump is somewhat sluggish.
Solution:
The hand pump has not been used for a longer period of time. This effect will disappear as the pump is operated.
