Weekly Maintenance

In addition to the steps in Daily Maintenance, complete the following tasks on the last working day of each week.

1.

Check and finger tighten all 16 screws for the tubing going into and out of each of the eight 3-way syringe valves.

2.

Check the plunger lock screws and syringe screws and tighten manually.

3.

Place the aspirating inlet tubing in a bottle with a recommended cleaning agent and flush the liquid system twice.

For instructions, refer to Perform Liquid System Flush. For cleaning agent options, refer to Infinium Assay Consumables and Equipment (document # 1000000084294).

4.

Allow the cleaning agent to react for at least 10 minutes.

5.

Place the same aspirating inlet tubing in a separate bottle with deionized water and flush the liquid system twice.

6.

Place the aspirating inlet tubing back in the original system liquid container and flush the system eight times.

7.

Empty and clean the system liquid container with 70% EtOH. Refill the container.

8.

Clean all other liquid containers to prevent deposition of crystals and growth of microorganisms.

Make sure to allow solvents (eg, ethanol) to evaporate before filling reagents into the containers.

9.

Make sure the barcode scanner on the RoMa arm remains in position B.

10.

Make sure the PosID3 barcode scanner is in a vertical position with the laser output window accessible.

11.

Turn off the instrument and wait for all system components to cool down.

12.

Remove the carriers in front of the PosID3.

13.

Check the barcode scanner on the PosID3. If necessary, clean the scanner with 70% EtOH on a lint-free tissue.

14.

Clean the No Tube sensor on the PosID3 with 70% EtOH on a lint-free tissue.
