SSF, Appendix
1. Using a scratch free flat surface, turn the pump over to gain access to the base of
the pump.
2. Undo the six screws holding the pump case halves together.
3. Place the pump upright and from the top carefully ease the halves apart, taking care
not to put any strain on the internal connecting cable looms that form a hinge between
the case halves.
WARNINGS
When a new SSF has been fitted to a pump, the pump must be tested using the
Syringe Size Sensor gauges (
part number 0131- 0202) available from Smiths
Medical. Page A-3 gives details of the Final Testing procedures.
Ensure that the AC mains supply is switched off and the pump's AC connector is
removed before opening the case halves.
CAUTION
During the removal and replacement of a pump's components, strict observance
to Electro Static Discharge (ESD) rules must be observed at all times i.e. an
earthing strap must be worn. Failure to apply ESD protection may result in
damage to the pump, resulting in its malfunction.
The screws, washers and associated items that are removed during the disassembly of the
pump are required during the reassembly.
Opening the case
1. With the pump case open as detailed above, remove and retain the screw from
beneath the umbilical board and displace the board in order to reveal the half-nut.
2. Disconnect the long thin spiral spring from its slot in the SSF, and pull out and
remove the half-nut connecting pin.
3. Observing the position of the SSF in the rear of the case, and the position of the
half-nut on the end of the large diameter support tube, lift the SSF and support tubes
assembly up and away from the pump.
4. Remove the large half-nut screw, prise the half-nut apart and remove it from the
support tube.
5. Slide the old replaceable SSF to the left, over and away from the small diameter
support tube.
6. Remove connector PL1 from the size sensor opto moulding and also remove the two
screws that hold the moulding in place.
Note:
The thickness of the size sensor opto moulding should be 4.65 mm (a new moulding and
longer fixing screws are supplied in the SSF kit). If an old type moulding is fitted, i.e. 3.00
mm thick, it may be difficult to obtain the correct syringe size sensor results when the new
SSF is fitted. If difficulty is experienced, contact your local representative or Smiths
Medical, Service Department.
