PURGE LINE SET FLUSH – 16OZ LIQUID

Why flush when you can PURGE?

PURGE LINE SET FLUSH 16OZ LIQUID allows you to tackle challenging system cleaning projects with confidence. Developed specifically for contractors who demand maximum flexibility, this professional-grade solvent excels in extreme temperatures where traditional aerosols lose pressure, making it ideal for cold-climate installations and winter service calls. The concentrated liquid format allows for precise application control, extended contact time for stubborn contaminants, and the ability to clean multiple systems with adjustable nitrogen pressure up to 200 PSI. Whether you’re recovering from severe burnouts, performing refrigerant conversions, or maintaining critical commercial equipment, PURGE Liquid delivers consistent, reliable results every time.

Key Features and Benefits:

• Extra cleaning power: Higher active concentration for faster dissolving of tough contaminants.
• Nitrogen-pressurized application: Customizable pressure from 50-200 PSI
• Equipment compatibility: Works with your existing flush equipment
• Concentrated value: More cleaning power per dollar
• Rapid contamination removal: Removes sludge, carbon residues, acids, oils, particulates, and water.
• Non-flammable, non-toxic: Worker-friendly formula without compromising performance.
• Versatile use: Ideal for new installs, retrofits, R‑410A and A2L conversions, change-outs, and post-burnout cleanups.
• Industry trusted: Preferred by professional HVAC contractors nationwide
• Low-boiling formula: Completely evacuates under vacuum – no residue
• Universal compatibility: Safe for copper, aluminum, steel, and elastomers – won’t damage system components
• No propellant restrictions: Compliant with Canadian regulations
• Certifications: EPA compliant formula

Directions:

Note: PURGE Liquid is compatible with industry-standard flush tanks and accessories currently available on the market. Vapco flush accessories coming soon.

Equipment Setup:

1. Establish Exit Point: Select one end of the line set as the exit point. Crimp or restrict the opening to increase solvent contact time and maximize cleaning effectiveness.
2. Prepare Recovery Container: Position a sealable waste container at the exit point to capture the contaminated flush/oil mixture for proper disposal.
3. Connect Flush Equipment: Attach your flush gun and hose assembly to the outlet valve of your flush tank (opposite the nitrogen inlet valve).
4. Fill Flush Tank: Remove tank cap and pour PURGE Line Set Flush Liquid into the flush tank. Standard tanks accommodate up to 24 ounces. Reassemble all components securely.
5. Connect Nitrogen Source: Attach a pressure-regulated nitrogen tank hose to the inlet side (ball valve side) of your flush tank.

Pressurization Procedure:

1. Set Nitrogen Pressure: Adjust pressure regulator to deliver 50 PSI of nitrogen. Slowly open the inlet ball valve to pressurize the flush tank. CAUTION: DO NOT EXCEED 200 PSI.
2. Isolate System: After pressurizing the flush tank, close both valves and disconnect the nitrogen supply hose. IMPORTANT: Never flush with nitrogen connected to flush tank.

Flushing Process:

1. Inject PURGE Liquid: Insert flush gun into the entry port of the line set. Inject PURGE in controlled 3-second bursts. One 16oz bottle typically cleans 2-4 residential line sets depending on contamination level and tubing diameter.
2. Nitrogen Purge: After injecting PURGE Liquid, connect nitrogen directly to the system and purge lines with 120 PSI nitrogen for 1-2 minutes. Capture all solvent/oil residue in the recovery container.
3. Verify Cleanliness: Clear solvent exiting the system indicates clean lines. If discharge shows contamination, repeat the flush procedure.
4. Final Evacuation: Pull deep vacuum (500 microns or below) to remove any residual solvent. Line set is now clean and ready for service.

Flushing After Compressor Burnouts:

1. Section Flushing: When possible, flush the system in manageable sections for thorough cleaning.
2. Component Isolation: Disconnect failed compressor and electrical connections. Recommend disconnecting or bypassing TXVs and capillary tubes for best results.
3. Remove Restrictions: Remove all filter driers before flushing.
4. Follow Standard Procedure: Use the line set flushing instructions above.
5. System Restoration: After flushing, evacuate system to 500 microns, perform leak check, and add appropriate oil charge and refrigerant.

Safety Guidelines & Additional Information:

Waste Disposal

• Contaminated flush will contain oils and system contaminants
• Transfer waste solvent to approved waste oil container for proper disposal
• Ensure containers are properly sealed if transport is required
• For larger systems requiring additional flush, simply close flush tank valve
• Refill tank with PURGE Liquid to continue cleaning process
• No need to disconnect equipment between applications

Safety Precautions

• No smoking or open flames near work area
• Ensure adequate ventilation, especially in equipment rooms
• Wear appropriate PPE: Safety glasses and chemical-resistant gloves
• Non-toxic, non-flammable formula for safer handling

Application Rates

• Residential Systems (1-5 tons): 4-8 ounces
• Light Commercial (5-15 tons): 8-16 ounces
• Severe Contamination: Increase volume by 50%
• One 16oz bottle: Typically flushes 2-4 residential systems
