6. Replacement of LCD
1. Separate front and rear housings of the pump.
2. Remove the pump door as described above.
3. Remove the pump assembly as described above.
4. Carefully place the pump assembly at a position in which the pumping
fingers are facing upwards.
5. Apply a piece of insulation tape across the fingers to keep them from
falling out (if they do fall out, refer to diagram: “Position of Pumping
Fingers in Pumping Block” for proper finger placement).
6. Remove the 3 screws that are holding the motor PCB.
7. Remove the screw holding the main PCB to the front housing.
8. Place the main PCB face up on the ESD mat so that the push buttons
are facing up.
9. Rotate the main PCB so that one hand can be used to grip the LCD
and the other can be used to cut the adhesive foam which holds the
LCD to the main PCB.
10. Gently lift on the LCD and use the sharp knife to score the adhesive
foam. After scoring the foam, disconnect the LCD from the main
PCB by pulling the collar out of the LCD connector.
11. Remove all leftover adhesive foam.
12. Install a new LCD by plugging it into the connector and engaging the
collar.
13. Place the LCD inside the white square that is printed on the Main
PCB.
14. Reassemble the pump in reverse order.
15. Perform Operational Checklist and Performance Acceptance Test
7. Software Update and Replacement
Note: Before disassembling the pump, make sure to make note of the calibration
settings, serial number, and date of production. Do not open pump without using
the Electro Static Discharge (ESD) equipment. Failure to do so could result in
damage to the internal circuitry of the pump.
Note: Software Updates will only be performed at the CME America Service
Center in order to maintain device DHR.
