Directions for Purge Line Set Flush Cylinders (5 lb & 10 lb):

WARNING: For use by professional HVACR technicians only. Purge operates at 140+ PSI. Failure to follow these instructions may result in injury or equipment damage.

Safety & Hazard Warnings

DANGER: Nitrogen Back-Pressure. Never connect the Purge cylinder directly to a Nitrogen line via a manifold.
Ventilation: Use only in well-ventilated areas. If flushing indoors, open windows or use fans to exhaust fumes.
PPE: Wear safety glasses and chemical-resistant gloves. Purge is a high-strength solvent that degreases skin instantly.

Phase 1: System Preparation

Before cracking the valve, ensure the system is isolated to prevent damage to sensitive components.

Isolate & Protect:
- Disconnect Components: Isolate sections for targeted cleaning. Never inject solvent directly into a compressor.
- Remove Restrictions: Bypass or remove TXVs, pistons, and filter driers. Solvent can lodge debris in these small orifices.
Establish Flow Path:
- Disconnect the line set from the indoor and outdoor units.
- Whenever possible, flush from the inside – out to the exterior.
- Place a waste container at the exit point to capture the solvent and sludge.
High-Pressure Connections (Critical Step):
- Because Purge operates at 140+ PSI, ensure all connections are secure.
- Gently wrench-tighten the connection between the cylinder valve and hose, and the hose to the flush gun.
- Caution: Do not over-tighten, but ensure a leak-proof seal before opening the cylinder valve.

Phase 2: The Flushing Process

Leverage the bulk volume to scrub large lines.

The “Pro Tip” Restriction:
- Crimp the Exit: Use pliers to slightly crimp or restrict the end of the copper discharge line.
- Why? This creates back-pressure, forcing the liquid solvent to fill the volume of large-diameter pipes completely.
Inject Purge:
- Open the cylinder valve. Pull the trigger on the flush gun.
- Inject solvent in controlled bursts based on tubing diameter:
  - Up to 1/2″ Tubing: 10–20 second burst per 50 ft.
  - Up to 7/8″ Tubing: 30–40 second burst per 50 ft.
The Nitrogen Chase (Mandatory):
- Do not rely on the cylinder pressure alone.
- Immediately after the solvent injection, disconnect the Purge cylinder and connect compressed Nitrogen.
- Blast Nitrogen through the line to drive the solvent plug and suspended debris out.

Phase 3: Verification & Completion

Ensure the line is chemically clean and dry.

Inspect the Discharge:
- Check the waste container. If the solvent is dark/black, repeat the flush.
- Continue until the discharge runs clear and colorless.
Evacuation:
- Pull a deep vacuum on the line set. Purge’s low boiling point ensures rapid boil-off under vacuum.
Disposal:
- Dispose of the waste solvent in accordance with local regulations (waste oil container).

FAQs

Frequently Asked Questions: Purge Cylinders (5lb & 10lb)

Application & Performance

Q: How many tons can a single cylinder clean? A: Purge Cylinders provide massive volume for commercial applications, offering a significantly lower cost per pound than aerosols.

• 5 lb Cylinder (PRG-SC): Cleans up to 25 Tons.

• 10 lb Cylinder (PRG-LC): Cleans up to 50 Tons.

Note: Actual coverage depends on line set length, diameter, and the severity of the burnout. These high-capacity tanks are designed to handle multi-circuit VRF systems and large commercial runs without running empty mid-job.

Q: Why is the pressure so high (140+ PSI)? A: We pressurize Purge to 140+ PSI to ensure the solvent maintains velocity through long vertical runs and complex piping. Low-pressure flushes (typically ~55 PSI) often lose momentum in these scenarios, allowing sludge to settle. The high pressure ensures a true mechanical scouring action.

Q: Can I flush a compressor or TXV? A: NO. Purge is designed for line sets and coils only. You must bypass or remove compressors, filter driers, and metering devices (TXVs/Pistons) before flushing. Injecting solvent into these components can trap debris, damage seals, or strip vital lubricants.

Q: Is a nitrogen chase required? A: YES. You must always chase the solvent with compressed nitrogen immediately after injection. While Purge pushes the bulk of the debris out, the nitrogen acts as a “squeegee” to remove the final solvent film and any suspended particulates before you pull a vacuum.

Hardware & Connections

Q: Do I need a specific injection valve or actuator?
A: No. Unlike aerosol cans that require a separate actuator tool, Purge Cylinders feature a standard 1/4″ male flare service valve built directly into the tank. You connect your flush hose directly to the cylinder valve.

Q: Which hose/gun kit should I use?
A: We recommend the PRG-HGK (Hose & Gun Kit). It includes a reinforced 60″ hose (PRG-H60) and a metal Flush Gun (PRG-SPR) capable of handling the 140+ PSI pressure.

Q: Can I use my standard manifold hoses?
A: While the cylinder fits standard 1/4″ hoses, we highly recommend using a dedicated flush hose. Using your manifold hoses for flushing risks contaminating your gauges and recovery machine with the burnout acid and sludge you are trying to remove.

Q: Are these cylinders refillable?
A: No. These are DOT-39 non-refillable cylinders. Once empty, they should be disposed of according to local metal recycling regulations. This ensures you always get fresh, high-purity solvent and avoids the liability of tracking expensive returnable tanks.

Troubleshooting

Q: The solvent coming out of the line is still dark. What do I do?
A: If the discharge is dark or black, it indicates heavy carbon or oil contamination.

1. Repeat the Flush: Continue flushing until the solvent runs clear.

2. Advantage of Bulk: With a 5lb or 10lb cylinder, you have ample reserve solvent to repeat the process on heavily contaminated lines without needing to grab a new can.

Q: The cylinder pressure seems low.
A: Extreme low temperatures will naturally lower the pressure of any gas.

• Solution: If the cylinder has been sitting in a freezing truck, allow it to warm to room temperature (60°F – 70°F) before use to restore full 140+ PSI pressure. NEVER heat with a torch or open flame.

Safety & Compliance

Q: Is Purge flammable? A: No. Purge is classified as Non-Flammable. It is safe for use in mechanical rooms and on rooftops where torch work may occur nearby.

Q: Is this product safe for A2L Refrigerant Conversions? A: Yes. Purge is ideal for converting systems to A2L refrigerants (like R-32 or R-454B). Its high-solvency formula completely removes mineral oil and alkylbenzene residues that are incompatible with new A2L lubricants.

Q: Does Purge leave a residue? A: No. Purge has a low boiling point of 106°F (41°C). This allows it to evaporate rapidly and completely under a standard deep vacuum, leaving zero residue inside the pipe.

Logistics & Shelf Life

Q: Why choose cylinders over aerosols? A: Cylinders are the professional choice for commercial contractors. They offer a lower cost per pound, reduce waste (fewer cans to throw away), and provide the continuous volume needed for VRF systems and large-diameter piping.

Q: What is the shelf life? A: Purge cylinders have a shelf life of 5 years from the date of manufacture when stored properly in a cool, dry place out of direct sunlight. Manufacture warranty of 1 year.

Q: How do I dispose of the waste solvent? A: The used solvent captured in your bucket will contain hazardous system contaminants (acid, oil, sludge). Do not dump it down the drain. Dispose of it in a waste oil container in accordance with your local EPA regulations.
