3. Sikkerhedsoplysninger
Always observe the following safety precautions when handling or installing the replacement sensor:
- Sluk: Ensure the refrigerant leak detector is completely powered off and disconnected from any power source before attempting sensor replacement.
- Håndteres med forsigtighed: The sensor is a delicate electronic component. Handle it by its base or housing to avoid damaging the sensing element or electrical contacts.
- Rent miljø: Perform sensor replacement in a clean, dry environment to prevent contamination of the new sensor.
- Refer to Detector Manual: Always consult the specific instruction manual for your Inficon TEK-Mate or Compass leak detector for additional safety guidelines and detailed sensor replacement procedures.
4. Opsætning og installation
Follow these steps to replace the sensor in your Inficon TEK-Mate or Compass refrigerant leak detector:
- Prepare the Detector: Turn off the leak detector and disconnect it from any power source. Allow the unit to cool down if it has been recently in use.
- Locate Sensor Compartment: Identify the sensor access compartment on your specific TEK-Mate or Compass model. This is typically a screw-on cap or a removable panel.
- Fjern den gamle sensor: Carefully unscrew or unclip the old sensor. Note its orientation for correct installation of the new sensor. Avoid touching the sensing element of the old sensor.
- Installer ny sensor: Gently insert the new Inficon 703-020-G1 sensor into the compartment, ensuring it is correctly seated and aligned with the electrical contacts. Do not force the sensor.
- Sikker sensor: Screw on the cap or reattach the panel, ensuring it is finger-tight or securely fastened according to your detector's manual.
- Tænd og test: Reconnect power to the leak detector and turn it on. Allow the unit to warm up as per its operating instructions. Perform a functional test to confirm proper operation and sensitivity.
5. Operating Considerations with New Sensor
After installing the new 703-020-G1 sensor, your leak detector should exhibit restored or improved sensitivity to refrigerants. It is recommended to:
- Allow Warm-up: Always allow the detector sufficient warm-up time as specified in its manual to ensure the heated diode sensor reaches its optimal operating temperature.
- Perform Calibration Check: If your detector has a calibration feature, perform a calibration check after sensor replacement to ensure accurate readings.
- Regelmæssig test: Periodically test the detector with a known refrigerant source to confirm its sensitivity and response time.
6. Vedligeholdelse
To maximize the lifespan and performance of your Inficon 703-020-G1 replacement sensor:
- Hold rent: Keep the sensor area free from dust, dirt, and moisture. Avoid direct contact with the sensing element.
- Korrekt opbevaring: If storing spare sensors, keep them in their original packaging in a cool, dry place away from direct sunlight and extreme temperatures.
- Udskiftningsplan: The lifespan of a heated diode sensor depends on usage and exposure to refrigerants. Replace the sensor when you notice a significant decrease in sensitivity or an increase in false alarms, even after cleaning.
7. Fejlfinding
If you encounter issues after replacing the sensor, consider the following:
- No Detection or Low Sensitivity:
- Ensure the sensor is correctly seated and making proper electrical contact.
- Verify the detector is fully warmed up.
- Check the detector's battery level.
- Confirm the new sensor is the correct model (703-020-G1) for your detector.
- Falske alarmer:
- Ensure the sensor area is clean and free from contaminants.
- Avoid using the detector in areas with high concentrations of non-refrigerant gases that might trigger false positives (e.g., solvents, cleaning agents).
- Detector Error Codes: Refer to your specific Inficon TEK-Mate or Compass leak detector manual for interpretation of any error codes displayed after sensor replacement.
If problems persist, contact Inficon customer support or an authorized service center.
