INSTALLATION PROCEDURES

INITIAL SETUP

3.2 INITIAL SETUP

Unpack the Instrument

1. Unpack all boxes.

2. Using the packing list, ensure that no items are missing including the proper reagents,

controls and calibrators.

3. Check the instrument for damage.

4. Check that the instrument has caution and compliance labels near the power connector.

5. Measure the line voltage that the MD II will be plugged into. Verify that the instrument

version (100 Vac, 120 Vac or 230 Vac) matches this line voltage. (The range and part

number are stamped on the serial number tag and also listed in Table 3.1-2.)

6. Remove packing materials. Open the lower chassis as necessary:

r Wire wrap around the vacuum pump

r Foam insert underneath the vacuum pump

7. Ensure that cards and connectors are seated properly in the lower chassis.

8. Verify that the AC Power/Vacuum Relay card is configured for the proper voltage range.

(Use Table 3.1-2 to match the proper range to the connector/jumper label.) The 230

VOLTS instruments ship with the higher-range connector (240 VOLTS) installed and

also include the lower-range connector, should the input supply be 220 Vac or lower.

Change to the 200 VOLTS jumper at this time if appropriate.

9. Lower the upper chassis and remove the upper chassis cover.

10. Check that all cards are seated properly, no connectors are loose, and all the DIP switches

and jumpers are set correctly. Refer to Appendix A for the correct settings, if necessary.

11. Verify that the AT power supply Ac Select switch is set to 115 for 100 Vac or 120 Vac

units and 230 for 230 VOLTS units. This switch is covered by the chassis rear panel and

can just be seen through the power cable cutout. To switch voltage settings, you must

remove the power supply.

12. Connect cables and power cords (Figure 3.1-1).

13. Install the peristaltic pump tubing around the pump spooler.

Note: Manually turn the pump several revolutions. If this is not done, the motor may not

be able to turn the pump.

CAUTION

Risk of damage to equipment. Turning the instrument’s power ON before the instrument is

completely setup could damage the instrument. Do not turn the instrument’s power ON until you have

completed connecting the reagents and the Printer.
