Maintenance Instructions - Ottobock 1C62 Triton Harmony Gebrauchsanweisung

Sufficient space should be available for the adapter to ensure proper function and eliminate
noise during walking.
7. Assemble the foam cover and finish off the outer shape of the foam cover in usual way with
carbon foot installed. Any compression of the foam cover by cosmetic stockings or SuperSkin
needs to be taken into account.
4.5.1 Cosmetic finish of the prosthesis
The 1C62 Triton Harmony 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 the tubing is not crimped or compressed in any way. The flange can be glued in place if ne-
cessary: apply thin layer of glue to flange surface and press into place. Once flange is secure,
any extra tubing can be cut to length or simply pressed into the cosmesis until end of tubing is
flush with flange.
Note: To achieve the best cosmetic appearance, we recommend that the foam cover is finished
with a Soft Touch stockinette.
Note: If salt appears on the outside of the stockinette, it can be washed away with warm water.
4.6 Adjustment and final assembly
Due to the high forces in the adapter section, it is indispensable to tighten the adjustment screws
of the tube adapter with a torque of 15 Nm (135 lb-in).
Use 710D1 Torque Wrench. Once you have attained the final setting for the prosthesis, use 636K13
Loctite to secure the set screws.

4.7 Maintenance instructions

• Foot assembly should be inspected after first 30 days (4 weeks) of use.
• Inspect the entire prosthesis for wear during normal consultations.
• Footshell may require replacement if wear is excessive.
Ottobock recommends replacing the 4X147 Functional Ring after approximately 1 year of use
because the stiffness and restoring force can decrease over time. Depending on activity and en-
vironmental conditions, this may become necessary at an earlier (or later) point in time. Reduced
shock absorption and slower generation of vacuum are typical indicators the patient may notice.
Note: New functional rings may feel stiffer for the patient on the initial days of use.
If vacuum performance decreases without a corresponding decrease in shock absorption perfor-
mance, one or both of the valves may have become clogged with debris. The best remedy is to
