Key Features:

• High moisture removal capacity.
• Effective acid removal.
• Solid core design for maximum filtration.
• 1/2 ODF (Outer Diameter Flare) connections for easy installation.

4. Setup and Installation

Proper installation is critical for the performance and longevity of the filter-drier and the entire refrigeration system. This component should be installed in the liquid line of the system.

Installation Steps:

1. System Preparation: Ensure the system is depressurized and evacuated before cutting into the liquid line.
2. Location: Install the filter-drier in the liquid line between the condenser and the expansion device. Ensure the flow arrow on the drier body points in the direction of refrigerant flow.
3. Cutting: Cut the liquid line cleanly to the correct length to accommodate the drier. Deburr the pipe ends.
4. Brazing: Use appropriate brazing techniques and materials (e.g., silver solder) to connect the drier to the copper lines. Protect the drier body from excessive heat during brazing by wrapping it with a wet cloth or using a heat sink compound. Avoid overheating, which can damage the desiccant material.
5. Leak Check: After installation, perform a thorough leak check using nitrogen or an approved leak detection method.
6. Evacuation: Evacuate the system to a deep vacuum (e.g., 500 microns or less) to remove all non-condensable gases and moisture.
7. Recharge: Recharge the system with the appropriate type and amount of refrigerant.

Refer to the overall system's installation manual for specific refrigerant charging procedures and pressure settings.

5. Operating Instructions

The York S1-404161 HPC 1/2 ODF FLTR-Drier is a passive component designed to continuously remove moisture and contaminants from the refrigerant. It does not require active user operation once installed.

Its function is integral to the system's overall performance. A properly functioning filter-drier helps prevent:

• Acid formation due to moisture reacting with refrigerant and oil.
• Corrosion within the system.
• Blockages from solid contaminants.
• Reduced system efficiency and potential compressor failure.

6. Maintenance

Filter-driers are typically replaced as part of routine system maintenance or during major service events (e.g., compressor replacement, system opening for repairs).

Recommended Maintenance:

• Regular Inspection: During routine system checks, visually inspect the drier for signs of external damage or leaks.
• Pressure Drop: A significant pressure drop across the filter-drier can indicate a clogged drier. This should be checked by a qualified technician using pressure gauges.
• Replacement Schedule: While there is no fixed replacement schedule, it is good practice to replace the filter-drier whenever the system is opened for service, or if there are indications of moisture or contamination.
• Post-Burnout Replacement: If a compressor burnout occurs, the filter-drier MUST be replaced, and a suction line filter-drier should also be installed temporarily to clean the system.

Always use genuine York replacement parts to ensure compatibility and performance.

7. Troubleshooting

Issues related to the filter-drier often manifest as broader system performance problems. Consult a qualified HVAC/R technician for diagnosis and repair.

Always consult a professional HVAC/R technician for complex system diagnostics.
