12.1.5 Empty and clean the waste water container

• Refill the distilled water container with demineralised or distilled water. Do not use tap water .

• Check if the filter is not cloged

• Place the distilled water sensor into the container and continue

with routine measurements.

Always check the liquid levels to avoid unintended interruption of runs.Every time when the distilled water container is refilled the waste water container must be emptied. The liquid sensor filter has to be checked if it is installed and free of discoloration.

Maintenance

Note

It is absolutely necessary to check the level in the waste water container (red label) constantly . The container should be checked every time before the system is switched on.

The waste water sensor (marked red) must be placed into the waste water container (red label) before using the system. This sensor monitors the liquid level in the container and gives an error message if the level is too high.

The following error message will be displayed:

STATE

Waste bottle full

The current measurement will be interrupted if the level is too high in order to avoid an overflow.

The following error message will be printed:

12.1.6 Cleaning and Disinfection of housing and waste box

Note

The waste water contains patient samples and test reagents and must be treated potentially infectious. Avoid any direct skin contact. Dispose of the waste water in compliance with biohazard and legal provisions.

Once a week the housing and the waste box should be cleaned and disinfected to avoid any contamination.

Do not use organic acids.

Do not use any organic acids to clean the instrument and the waste box. Only use a cleaner designed for cleaning and disinfecting instrument surfaces and waste box. Use a dampened cloth. Never spray or pour any liquids onto or into the system which may negatively impact the analyzer’s functions.

If liquids have accidentally run into the system contact the customer service of the distributor or the manufacturer.

Avoid any direct skin contact with samples and/or test reagents as well as those parts of the instrument which might be contaminated with samples and/or test reagents. These parts are potentially infectious. If samples were spilled onto the system wipe them off immediately and disinfect the instrument. Reagents might irritate the skin or mucous membranes. Observe the manufacturer’s instructions in the package insert how to handle the reagents properly . Make sure to dispose of the sample and test material in compliance with biohazard and legal provisions.

12.1.7 How to dispose of used disposables

Maintenance

Remember to dispose of used cuvette bars, primary tubes, and reagent vials in compliance with legal provisions.

12.1.8 Install the

diluter syringe and tubes

All disposables used with the system must be treated as potentially infectious. Avoid any skin contact with sample and reagent material which might be on the disposables. Dispose of used disposables in compliance with legal provisions or laboratory regulations. Do not put used disposables, samples and reagents into the usual garbage. Cuvette bars might not be resistant to organic acids. Therefore do not use organic acids unless they are expressly permitted.

Install the 250 µl dilutor syringe to the dilutor of the system according, to the figure . When properly installed, the syringe should not be wedged, and must be watertight.

• Press the syringe piston completely into the dilutor syringe.

• Open the locking screw.

• Push the syringe holder at the dilutor downward.

• Place the opening of the syringe piston onto the syringe hol-

der of the dilutor.

• Screw the top of the syringe onto the adapter of the dilutor valve.

• Tighten the locking screw.

• Connect all tubings to the dilutor valve.

Maintenance

Installing the tubes

The liquid system requires tubing between the diluter and pipettor. Connect the tube as follows:

• Take the tubing out of its plastic accessory bag.

• Remove the red plastic screw at the steel tubing of the pipettor.

• Screw the tubing (white screw) onto the diluter valve until hand-tight.

• Run the other end of the tubing through the tubing guides on the back of the instrument.

• Screw the end into the top of the arm (black screw). Make sure it fits properly and watertight.

• Review the entire tube path to ensure the tubes will be neither bent nor squeezed during instrument operation.

12.1.9 Replace the liquid sensor filter for dist. water

In order to avoid clogging of the pipettor with particles a plastic filter has been installed on the end of the dist. water sensor.

To replace the filter proceed as follows:

• Remove the dist. water sensor from dist. water container and

dry it carefully.

• Remove the filter from the end of the sensor.

• Install the new one by pressing it all the way down to the filter

holding device.

Make sure not to damage the filter during installation.

• Place the dist water sensor into the dist. water container and

start a rinsing cycle before the first measurement will be started. this has to be done to avoid to have air bubbles in the liquid system.

guide

This trouble shooting guide describes all the error messages of the analyzer they can occur. These messages will be displayed and in some cases printed out automatically . This guide gives a help to the service technician to find out the cause why the errror occurs and what kind of actions can be started to solve the problem. The error messages are subdivised in 6 categories:

• Module errors see chapter 13.1

• System messages see chapter 13.2

• ChipCARD errors/messages see chapter 13.3

• Measuring errors see chapter 13.4

• Special messages see chapter 13.5

• Errors during initialisation see chapter 13.6

13.1 Module Errors

Module errors are errors, which are communicated from one control module to the user interface. These error messages will either be displayed via print out or shown at the display. Both the error message and the module which communicates the error will be printed and displayed. Module errors usually lead to an immediate break of the respective function. The following pages are describing the messages itself , the causes why an error occours and what kind of actions can be started to solve the problem.
