Flow chart:
Cover the hole on the inside of the socket with a small piece of paper and tape that is not
airpermeable (such as PVC tape). Cycle the pump until a vacuum of 508-847mbar (15 – 25 inHg)
is reached. Check if vacuum level is maintained when the pump is not being cycled.

4.7 Cosmetic finish of the prosthesis
The Harmony P3 is delivered with two different exhaust valve attachments:
• a short piece of tubing with installed muffler and Double Barb Connector pre-installed at the
exhaust valve
• a long piece of tubing with an exhaust flange
If a cosmetic cover of the prosthesis is desired use a cover with a 34 mm centre hole.
NOTICE
Function loss as a result of improper installed cosmetic cover. If using a 6R8 Foam Cover,
it is important that the cover is not compressed along the length of the foam, as this can affect
the function of the Harmony pump.
Once the Foam Cover is in place, determine location of exhaust flange and drill or cut a 6 mm
hole. Ottobock recommends placing the exhaust flange medially at the ankle, just above the top
of a patient's shoe. Next, insert tubing (Fig. 12, Pos. 2) and flange (Fig. 12, Pos. 3) into the hole
of cosmetic cover and connect tubing to Double Barb Connector (Fig. 12, Pos. 1). Make sure that
