4. സജ്ജീകരണം
Follow these steps to prepare your ROREC unit for operation:
- അൺപാക്ക് ചെയ്യുന്നു: Carefully remove the unit from its packaging. Inspect for any shipping damage.
- പ്ലേസ്മെൻ്റ്: Place the unit on a stable, level surface in a well-ventilated area, away from direct sunlight or heat sources. Ensure adequate clearance around the unit for airflow.
- ഇലക്ട്രിക്കൽ കണക്ഷൻ: Connect the power cord to a grounded 230V AC, 50/60Hz electrical outlet. Verify the power supply matches the unit's requirements.
- ഹോസ് കണക്ഷനുകൾ: Connect the appropriate refrigerant hoses from the system to be serviced to the 'INPUT' port of the recovery unit, and from the 'OUTPUT' port to the recovery tank. Ensure all connections are tight to prevent leaks.
5. പ്രവർത്തന നിർദ്ദേശങ്ങൾ
This section outlines the general procedure for refrigerant recovery. Specific procedures may vary based on the refrigerant type and system configuration.
- തയ്യാറാക്കൽ: Ensure all safety precautions are observed. Connect the unit as described in the 'Setup' section. Open the valves on the recovery tank.
- പവർ ഓൺ: Turn the main power switch to the 'ON' position. The unit should start.
- Valve Settings: Set the 'INPUT' and 'OUTPUT' valves on the unit to the 'RECOVER' position.
- Monitor Recovery: Observe the pressure gauges. The input pressure should gradually decrease as refrigerant is recovered from the system. The output pressure will indicate the pressure in the recovery tank.
- Liquid/Vapor Recovery: The unit is capable of both liquid and vapor recovery. For faster recovery, especially with large systems, start with liquid recovery if the system allows.
- പൂർത്തീകരണം: Recovery is complete when the input pressure gauge reads a vacuum (typically -0.5 to -0.8 bar, depending on refrigerant and ambient temperature) and no more refrigerant is being transferred.
- Purging (Self-Cleaning): After recovery, set the valves to the 'PURGE' position to clear any remaining refrigerant from the unit's internal components. This prevents cross-contamination between different refrigerants.
- പവർ ഓഫ്: Once purging is complete, turn the power switch to 'OFF'. Close the valves on the recovery tank and disconnect hoses.
6. പരിപാലനം
Regular maintenance ensures the longevity and optimal performance of your recovery unit.
- ഫിൽട്ടർ മാറ്റിസ്ഥാപിക്കൽ: The unit may contain an internal filter/dryer. Consult the specific product documentation or Rothenberger support for recommended replacement intervals and procedures. A clogged filter can reduce recovery efficiency.
- വൃത്തിയാക്കൽ: Keep the exterior of the unit clean. Use a damp cloth to wipe down surfaces. Do not use harsh chemicals or solvents. Ensure ventilation grilles are free from obstructions.
- ഹോസ് പരിശോധന: Regularly inspect all refrigerant hoses for cracks, wear, or damage. Replace any compromised hoses immediately.
- സംഭരണം: When not in use, store the unit in a clean, dry environment, protected from extreme temperatures. Utilize the integrated storage compartment for hoses and the power cord.
