4. Istruzzjonijiet ta' Setup

1. Ipprepara s-Sistema: Ensure the HVAC or refrigeration system is depressurized and isolated before beginning the flushing process.
2. Select Nozzle and Pig: Choose the correct size nozzle and a corresponding foam pig for the line set you intend to clean. The kit includes nozzles from 3/8" to 7/8".
3. Waħħal iż-żennuna: Securely attach the selected nozzle to the Pro-Flush injector tool. Tighten the thumb screw on the injector tool until it is thumb-tight.
4. Add Solvent: Open the chamber of the injector tool. Pour approximately 2 to 3 ounces of PF-16 flushing solvent into the chamber.
5. Insert Foam Pig: Carefully insert a foam pig into the chamber on top of the solvent.
6. Close Chamber: Close the injector tool chamber securely.
7. Connect Nitrogen Source: Connect the injector tool to a compressed nitrogen source. It is recommended to use a pressure of 70 PSI.
8. Prepare Catch Bag: Position the catch bag at the exit point of the line set to collect the expelled pig, solvent, and contaminants.

5. Istruzzjonijiet Operattivi

Once the kit is set up and connected, proceed with the flushing operation:

1. Initiate Flush: Firmly pull and hold the trigger on the Pro-Flush injector tool. The compressed nitrogen will propel the foam pig and solvent through the line set.
2. Observe Pig Exit: Monitor the exit point of the line set for the foam pig to emerge into the catch bag. The pig acts like a squeegee, pushing oils, contaminants, and the flushing solvent out of the line.
3. Irrepeti jekk meħtieġ: For heavily contaminated lines, you may need to repeat the process with a fresh foam pig and additional solvent until the expelled pig and solvent appear clean.
4. Nitrogen Purge: After flushing, continue to purge the line set with nitrogen to ensure all solvent residue is removed. The hydrophobic nature of the foam pigs helps to push out all liquids effectively.

6. Manutenzjoni

Proper maintenance of your Pro Flush kit components ensures longevity and effective performance:

• Cleaning Foam Pigs: Foam pigs are reusable. If they become dirty, clean them using dish soap or a detergent that effectively cuts grease and oil. Wash them with warm water and allow them to dry completely before reuse. Ensure they are in good condition before re-inserting them into the line.
• Cleaning Injector Tool: After each use, clean the injector tool to remove any solvent or contaminant residue.
• Ħażna: Store all components in the provided storage case to protect them from damage and keep them organized. The EVA foam tray is designed to hold all parts securely.

7 Issolvi l-problemi

If you encounter issues during the flushing process, consider the following:

• Pig Not Advancing: If the foam pig does not advance through the line set, check the nitrogen pressure. Ensure it is at the recommended 70 PSI. Verify that the nozzle is correctly sized for the line and that there are no blockages in the injector tool.
• Persistent Contamination: If multiple flushes do not remove all contaminants, the line set may have severe internal damage or blockages that cannot be cleared by flushing. In such cases, replacement of the affected line section is recommended.
• Kinked Lines: While the foam pigs are designed to navigate bends, severely kinked or improperly brazed lines (e.g., sharp 90-degree bends) can impede the pig's movement. If a line is kinked, it indicates an efficiency problem and should ideally be repaired or replaced for optimal system performance.
