BIOHARZARD Wear gloves and lab coat and, if necessary, goggles during maintaining process.

Before maintenance or packaging for transportation, the used instrument should be disinfected to ensure personal safety.

5.1 Daily Maintenance 1、 Use neutral wash solution and wet cloth to remove the spillage on the

instrument.

2、 Wash the tubing with distilled water or DI water before shutting down the analyzer (for instrument installed with flow cell).

5-2

3、 When the system is not in use, make sure that the tubing and the flow cell is filled with clean distilled water (or DI water).

5.2 Weekly Maintenance 1、 Wash the waste bottle interior with clean water. Soak the bottle with

disinfector if necessary.

2、 If the instrument will not be in use for a long time. Detach the pump head from the pump to elongate the service life of the pump tubing.

5.3 Irregular Maintenance

5.3.1 Cleaning Flow Cell

5.3.1.1 Low Background

Contamination of the flow cell or bubble in the flow cell might cause low background. You can use the ethanol solution to clean the flow cell ( also applies for bubble in the flow cell). The procedure is as follows:

1) Click Wash on the software to wash the tubing. After 5 seconds, click Stop.

2) Prepare about 5 ml ethanol solution in the tube. Put the aspiration tubing into the tube and click Wash. After 5 seconds, click Stop. Wait for 10 seconds.

3) Wash with ethanol solution for 5 seconds again, and then wait for 10 seconds. Wash the tubing with DI water for 10-20 seconds. The cleaning is completed.

4) Other recommended wash solutions include: 0.1N NaOH (KOH) solution (with some surfactant); or, enzyme solution capable of decomposing the protein; or, reagent used in chemistry analysis, capable of removing the protein, total protein reagent (biuret) and etc.

5.3.1.2 Before switching to other tests

Before switching to other tests, it is recommended the flow cell be washed with distilled water (or DI water). This is very necessary for tests which carryover might take place, or samples whose concentration differs a lot. The cleaning should last for no less than 5 seconds. The amount of distilled water (or DI water) should be around 1.5 ml. You can also use the wash solution specifically for chemistry analyzer to wash first, then with the distilled water (or DI water).

5.3.1.3 Cleaning Exterior of the Flow Cell

If the optical surface of the flow cell is contaminated, use cloth soaked with certain amount of absolute alcohol to clean it.

5-3

WARNING Some reagents are corrosive. Exercise caution when handling the

reagents. In case the reagents or wash solution spill into your eyes, rinse them with much water and consult an oculist.

5.3.2 Adjusting the Photoelectric Gain When the alarm message “Light signal too weak” or “Light signal too strong” appears, please check whether there is air in cuvette or whether the cuvette is placed right. If not, please adjust the photoelectric gain.

After entering the Maintenance screen, click Gain adjust to pop up the Gain adjust page. Click Start and do as the system prompts. The system will complete the photoelectric adjustment and parameter configuration automatically. If the adjustment failed, possible reasons are: bubble in the flow cell or dirty optical elements or low intensity of the lamp, or damaged boards. After photoelectric gain is completed, wait for 10 min before testing. Otherwise, test result might be affected because of unstable light source.

NOTE The lamp must be replaced when its light intensity attenuates to the

specified threshold. When the range of background preset by the system can not be restored by adjusting the photoelectric gain, it might be possible that the light intensity attenuates to the specified threshold and the lamp should be replaced timely.

5.3.3 Calibrating the Peristaltic Pump The flow volume of the peristaltic pump might change after being used for a certain period, so it is necessary to calibrate the flow volume of the pump, if obviously incorrect aspiration volume of the pump is observed.

5.3.4 Replacing the tubing When the instrument is in use, if you notice that the instrument can not aspirate or aspiration volume decreases obviously, check for leakage in the peristaltic pump. If yes, the pump tubing might be broken and it should be replaced. A pump tubing is in the accessory package (outer diameter 3.2mm, length 150-160mm, yellow).The procedure for replacing is shown as follows:

1 Shutdown the instrument and disconnect the power cable between the instrument and the power supply.

5-4

2 Locate the position where the peristaltic pump is installed. Pull out the tubing that goes through the backboard of the analyzer for 40-50mm until the adapter is exposed. Pinch the two buckles on the left and right side of the pump shell and detach the pump head carefully.

3 After detaching the pump head, unplug the tubing (yellow) whose adapters are closer to the pump head.
