Use the Foot Horn to don and doff the foot shell. Remove the CPI sock and replace as needed.
ENDOSKELETAL MOUNTING
Use only high quality proximal endoskeletal components.
STATIC ALIGNMENT
For optimal function, balance the patient's weight evenly between the heel and toe (Figure 4).
▪ The Celsus iVT was designed with a 3/8" (10.0 mm) heel rise.
▪ The load line divides the foot at 1/3 heel lever and 2/3 toe lever.

INSTALLING THE CELSUS IVT
College Park recommends the iVT valve kit to connect the system to the socket. Use of other products is the
sole responsibility of the provider.
TUBE CONNECTION
1.
Attach the tube to the hose connector.
2.
Cut the tube to a proper length and connect to the socket.
3.
Use the supplied tube retainer to secure the tube to the pylon or other adapter.
4.
Position the tube on the medial side to avoid damage.
5.
Once assembled verify the pump is working properly; creating vacuum during gait and not leaking air.
TUBE INSPECTION
The tube is the most sensitive part of the Celsus iVT and should be fitted carefully. Verify the tube is NOT:
▪ Folded or pinched (Figure 2)
▪ Contacting sharp objects
▪ Punctured
CHANGING HOSE CONNECTOR SIDE
The hose connector is pre-assembled for a left foot and can be reconfigured for a right foot.
1.
Use a 5/16 wrench to loosen the hose connector and exhaust vent.
2.
Switch the positions. Ensure the check valves are oriented in the correct direction for proper function (Figure 3).
3.
Retighten. Torque to 35 in-lbs (4 N-m).
