FINISHING / LINER OPTIONS
Össur recommends that the Unity System is used with an Iceross Seal-In
liner.
Caution: Make sure the Flex-Foot sock does not interfere with the Unity
System as it could compromise the function of the pump.
THE TUBE
The tube is the most sensitive part of the Unity System and special
attention should be paid to it for potential functional issue that might
arise.
Caution: Ensure that Unity tubing is not compressed or folded by the
application of cosmetic finishing.
Make sure the tube is NOT:
• Folded (Figure 3).
• Pressed up against sharp objects.
• Punctured.
• Dangling during gait.
• Located laterally, as there is more likelihood of damage.

Check the following:
• Is the liner sealing the limb/socket?
• Is there a leakage in the socket?
• Is the tube punctured?
• Is the membrane punctured or torn?
• Has the membrane been pulled out of the membrane housing?
• Is there dust or grit inside the system?
• Is the tube fully inserted on the inlet port? (Check both at the Unity
Socket valve and at the Unity Membrane housing)
• Are the inlet and outlet ports tightened?
• Is the Unity Socket valve leaking?
• Is the sock inside the foot cover affecting the systems mechanical
movements?
