. Using a designated -component PU adhesive putty, bond the adapter
(A) assembly (Fig. ) to desired location on the socket (Fig. ).
. Wrap thermoplastic socket and adapter firmly with glass reinforced
casting tape, enabling test fitting of the prosthesis (Fig. ).
. Drill through housing dummy into cast using a sharp mm drill bit.
Take care to align drill with centerline (Fig. ).
. Remove housing dummy (X) and replace with seal (B) / duckbill
valve (C) / mesh filter (D) and then screw in the expulsion housing
(E) / E connector (F) (Fig. ).
Note: When inserting the housing/connector, make sure that the
seal/valve/mesh is not crooked, otherwise the housing may not hold
vacuum properly.
. Place large seal (G) / O-ring (H) below housing. Complete assembly
with the plate (I/J/K/L), applying medium strength thread locker to
-hole screws and torque twice to Nm (Fig. ).
Note: Make sure threads are clean and provide full engagement of
screws without resistance. Only use screws supplied with kit.
. [For L-, L- and L-] Secure Unity tube to the
connector on the plate (J/K).
Laminated Socket Procedure
. Drape a layer of ~mm PETG or equivalent rigid thermoplastic sheet
over cast positive (Fig. ). Roughen distal area.
Note: Distal area must be clean of dirt, dust, and grease, as otherwise
the bonding connection may not work.
. Screw housing dummy (X) into socket adapter (A) (Fig. ). Using a
designated -component PU adhesive putty, bond the adapter
assembly to desired location directly on thermoplastic layer (Fig. ).
Take care to fill the center area for a bubble free bond between
housing dummy and thermoplastic layer.
. Remove housing dummy (X). Place lamination dummy (X) in
adapter (Fig. ).
. Tie reinforcement material in groove on socket adapter and do a
second tie between socket and adapter. Apply the reinforcement
material layup to agree with the expected stress (Fig. ).
. Apply PVA bag and impregnate laminate with conventional methods
(Fig. ).
. Tie around lamination dummy with electrical tape to push out the
resin between the PVA bag and dummy. This will produce clean edge
and minimize finishing work (Fig. ).
. Once resin has set, drill through lamination dummy (X) into cast using
a sharp mm drill bit. Take care to align drill with centerline (Fig. ).
. Remove excess resin, PVA bag and lamination dummy (X). Remove
plaster from inside of socket.
. Place seal (B) / duckbill valve (C) / mesh filter (D) and then screw in
the expulsion housing (E) / E connector (F) (Fig. ).
Note: When inserting the housing/connector, make sure that the
seal/valve/mesh is not crooked, otherwise the housing may not hold
vacuum properly.
. Place large seal (G) / O-ring (H) below housing. Complete assembly
with the plate (I/J/K/L), applying medium strength thread locker to
-hole screws and torque twice to Nm (Fig. ).
Note: Make sure threads are clean and provide full engagement of
screws without resistance. Only use screws supplied with kit.
