FITTING THE UNITY SYSTEM
note: To connect the system to a socket a Unity Socket Valve Kit is
recommended, the use of other applications is the sole responsibility of
the provider.
1. Fit the user with the foot containing the system
2. Cut the tube to correct length and connect to the Unity System and
the socket (using the Unity Socket Valve kit)
3. Use the supplied tube fixture to secure the tube against the foot. The
tube should be located medially rather than laterally to avoid damage
during ambulation.
Once the Unity System has been connected make sure the pump is
working properly; creating vacuum during gait and not leaking air.
DISASSEMBLING / ASSEMBLING THE UNITY SYSTEM
The Unity System can be dissembled in case it needs to be cleaned or for
troubleshooting purposes.
caution: The Unity System should only be disassembled / assembled by
a clinical specialist.
caution: The inlet and outlet (Figure 4) ports on the membrane housing
should not be disassembled unless absolutely necessary. This part of the
system contains miniature duckbill valves that are easily lost and can
cause the Unity System to malfunction if not correctly reassembled.
HOW TO CHANGE MEMBRANE IN THE UNITY SYSTEM
1. Use the Flex-foot shoehorn (or equivalent) to remove the foot from
the foot cover.
2. Disconnect the tube from the Unity Membrane housing.
3. Untighten the screw that fastens the membrane housing to the Vari-
Flex XC pyramid.
4. Follow figure 5.
5. Lubricate the membrane before sliding it into the housing with
Iceross Clean&Simple Spray or equivalent.
