Safety Information
- Always ensure the RV refrigerator is turned off and cooled down before attempting installation or maintenance.
- Wear appropriate personal protective equipment, such as gloves, to prevent cuts from screen edges.
- Keep small parts, like cable ties, out of reach of children.
- Do not obstruct the refrigerator vent openings beyond what the screen is designed for, as this can impair appliance function.
Installation Instructions
The Camco 42139 RS620 screens are designed for easy installation using the provided cable ties. Ensure your Dometic RV refrigerator vents have 20-inch long louver openings for proper fit.
- Prepare the Vent: Ensure the refrigerator vent area is clean and free from debris.
- Position the Screen: Place one of the stainless steel insect screens over a louver opening of your Dometic RV refrigerator vent. The screen should cover the entire opening.
- Secure with Cable Ties: Thread a cable tie through the mesh of the screen and around a secure point on the vent louver or frame. Ensure the screen is held firmly against the vent.
- Tighten Cable Ties: Pull the cable tie tight to secure the screen in place. Trim any excess length from the cable tie for a neat finish.
- Repeat for Remaining Screens: Follow steps 2-4 for the remaining two screens, ensuring all louver openings are adequately covered. Use additional cable ties as needed to ensure a snug fit and prevent gaps.
- Verify Installation: Gently tug on each screen to confirm it is securely attached and there are no gaps large enough for pests to enter.
Operation
Once installed, the Camco 42139 RS620 Flying Insect Screens operate passively by providing a physical barrier. No further action is required for their function. They allow air to circulate freely while preventing pests from entering and potentially damaging your RV refrigerator's internal components.
Maintenance
- Regular Inspection: Periodically inspect the screens for any signs of damage, wear, or accumulation of debris.
- Cleaning: If debris or dirt accumulates on the screens, gently brush it off or rinse with water. Ensure the screens are dry before re-installation if removed for cleaning.
- Secureness Check: Occasionally check that the cable ties are still tight and the screens are securely in place. Replace any broken or loose cable ties.
Troubleshooting
As a passive protective device, the insect screens typically do not require complex troubleshooting. If you encounter issues:
- Pests are still entering: Re-examine the installation to ensure there are no gaps between the screen and the vent frame. Tighten or add more cable ties if necessary. Verify that the screens are correctly sized for your specific Dometic RV refrigerator vents.
- Screen is loose: Check the cable ties. If they are loose or broken, replace them with new ones, ensuring a tight fit.
