ACCESSORIES

Directions:

Important pressure notice: Purge operates at higher pressures (140+ psi). For safety and leak prevention, gently wrench-tighten the connections:

Between the actuator (injection valve) and hose
Between the hose and the Purge-flush Gun
Do not over-tighten.

Establish the exit point: Choose one end of the line set as the discharge point. When possible, work from inside to outside.
Create a slight restriction: Crimp or partially restrict the exit to increase mass flow and contact time of Purge through the tubing.
Containment: Place a small container at the exit to capture solvent and contaminants.
Deliver Purge: (typical starting guidance; actual amount varies by oil load, line configuration, and contamination)
1. Up to 1/2 in. tubing: 10–20 second burst per line for every 50 ft
2. Up to 7/8 in. tubing: 30–40 second burst per line for every 50 ft
Nitrogen Purge: Immediately chase the Purge with nitrogen to drive solvent through the line set and maximize cleaning power. This helps ensure the solvent reaches the end of the run and removes loosened contaminants without waste.
Inspect discharge: Check the catch container; it should show oils and other contaminants. Empty or replace the container and repeat step 3 (and step 4) until the discharge runs clear.
Evacuate
Pull a vacuum on the line set to remove any residual solvent and moisture. Purge’s low boiling point promotes rapid boil-off under vacuum.
Completion

Once discharge is clear and evacuation is complete, the line set is clean and ready for service. Reassemble and return the system to operation.

Safety Guidelines & Additional Information:

System Preparation

Isolate sections: Disconnect components for targeted cleaning
Remove restrictions: Bypass compressor, TXVs, and remove filter driers
Establish flow path: Create clear inlet and outlet points
Prepare recovery: Set up containers for waste collection

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

Safety Precautions

Ensure adequate ventilation, especially in equipment rooms
Wear appropriate PPE: Safety glasses and chemical-resistant gloves
Non-toxic, non-flammable formula for safer handling
