Appendix, SSF
Remove any shim/s that were attached to the size sensor opto moulding. If required clean
the shim area with a suitable solvent. The shim sizes provided in the kit are
0.6, 1.0, 1.2
and 1.4 mm. If necessary, use a combination of shims to obtain the thickness required, up
to a maximum of 2.4 mm. During production at Smiths Medical, a 1.6 mm shim is initially
fitted to the pump.
Using the modified SSF, reassemble in reverse order to that given in steps (1) to (6) above,
all the components that were disassembled.
Taking care not to trap any leads, assemble the casing ensuring that the case halves have
snapped together and that the front and rear mating edges are equal and parallel. The six
case screws should be tightened to a torque of between 70 and 75 cNm in the order shown
in
Figure A.2.

Figure A.2 Order for tightening the case screws
When a new SSF has been fitted, the pump must be subjected to the appropriate
Functional Test procedures given in the associated Service Manual.
Before carrying out the syringe size sensor tests, ensure that the pole clamp has been
correctly fitted and the six case securing screws have been tightened to a torque of
between 70 and 75 cNm (see
Figure A.2).
The Syringe Size Sensor tests are performed with the pump's plunger clamp at each of the
two following positions:
1. 40 mm from the right-hand-side of the plunger clamp travel, and
2. at the extreme left-hand-side of the plunger clamp travel.
Also, the pump must be Configured during the tests to operate with the ‘BD Plastipak’
syringe.
Table A.1 on page A-5 lists the gauges that must be sequentially loaded onto the pump in
order to verify that the Syringe Size Sensor mechanism is operating correctly.
The small adjustment grub screw in the SSF must be correctly set (see page A-4) before
carrying out the Syringe Size Sensor tests. The small anti-tampering cap above the grub
screw must then be fixed into place using a minimal amount of Loctite 414.
