Opening the pump casing
The casing must be opened to carry out adjustments that may be required to the occlusion
thrust and for various repair procedures.
Repair procedures are detailed in Chapter 5.
Each time the casing separated and reassembled, the syringe size functional tests detailed
on page 6-1 must be completed.
1. Disconnect the AC power connector and utilising a scratch free flat surface, turn the
pump over to gain access to the base.
2. Undo and retain the six screws that hold the casing halves casing together. One of
the screws is situated in a channel in the rear cover.
3. From the top of the pump carefully ease the casing halves apart, taking care not to
put any strain on the internal connecting cable looms that form a hinge between the
casing halves.
Being careful not to trap any leads, assemble the casing by reversing steps (2) and (3) detailed
above. Ensure that the case halves have ‘snapped’ together and that the front and rear mating
edges are equal and parallel. Tighten the screws to a torque of between 70 and 75 cNm in the
order shown in the
Figure 2.1.
