It is compatible with all refrigerants and oils.

2. Safety Information

Always prioritize safety when working with refrigerants and chemicals. Follow these guidelines:

• Wear appropriate personal protective equipment (PPE), including safety glasses and gloves, when handling refrigerants and the test kit.
• Perform tests in a well-ventilated area.
• Avoid direct contact with the test solution. In case of contact, rinse thoroughly with water.

4. Setup

No extensive setup is required for the QT2000 kit. Ensure you have a clean, dry surface to work on and access to the refrigerant or oil sample to be tested.

1. Ensure the refrigerant system is safely depressurized or the oil sample is accessible.
2. Carefully remove the test vial from its packaging.
3. Do not open the vial until ready to perform the test.

5. Operating Instructions

Follow these steps to perform an acid test:

1. Collect Sample: Obtain a small sample of the refrigerant or oil from the system. Ensure the sample is representative and free from gross contaminants.
2. Open Vial: Carefully twist or break open the cap of the QT2000 test vial.
3. Introduce Sample: Add a few drops of the refrigerant or oil sample into the test vial. The exact amount is not critical, but ensure enough to interact with the reagent.
4. Observe Color Change: Within two seconds, observe the color of the solution in the vial.
5. Interpret Results: Refer to the 'Interpreting Results' section below for guidance.
6. Dispose: Properly dispose of the used vial and sample according to environmental regulations.

6. Interpreting Results

The QT2000 QwikCheck Acid Test Kit provides a clear visual indication of acid presence:

• No Color Change (Remains Yellow/Original Color): This indicates that no inorganic acids are present above the ARI-700 limit of 1 PPM. The system is likely free of harmful acid contamination.
• Color Change (Changes from Yellow to Red/Pink): This indicates the presence of inorganic acids above the ARI-700 limit of 1 PPM. Further investigation and corrective action, such as system flushing or oil replacement, may be necessary.

7. Maintenance

The Protech QT2000 QwikCheck Acid Test Kit is a single-use item and does not require maintenance. Store unused kits in a cool, dry place away from direct sunlight to ensure reagent stability.

8. Troubleshooting

If you encounter issues or unexpected results:

• No Color Change with Suspected Acid: Ensure the sample was properly collected and introduced into the vial. Verify the kit has not expired.
• Unclear Color Change: Ensure adequate lighting for observation. If in doubt, repeat the test with a new vial.
• Kit Damage: Do not use a kit if the vial appears damaged or compromised.
