TROUBLESHOOTING
Unstable Pressure
X Problem: Pressure cannot be generated correctly, or set pressure does not remain stable.
X Solutions:
•
Check that all adapters and pressure fittings have been tightened sufficiently to eliminate leaks.
•
Confirm test fluid does not contain air (air in the fluid can increase adiabatic effects). Replace test fluid if necessary.
•
Replace hose (hose expansion can cause unstable pressure).
Pressure does not Increase
X Problem: The system fails to indicate a pressure increase after considerable pumping action of the handle.
X Solutions:
•
Close the pressure vent valve.
•
Remove the fill plug, and push the middle of the Check Valve In. If the vent valve cannot be reached because it’s not aligned with the fill plug,
loosen the reservoir lid and rotate until aligned.
•
Check that all adapters and pressure fittings have been tightened sufficiently.
•
Pump requires service (please contact your local sales office for advice).
