Consignes de sécurité

Always read and understand all safety warnings and instructions before operating the VRR24M-C unit. Failure to do so may result in serious injury or equipment damage.

• Équipement de protection individuelle (EPI) : Always wear appropriate PPE, including safety glasses, gloves, and protective clothing, when handling refrigerants.
• Ventilation: Operate the unit in a well-ventilated area to prevent the accumulation of refrigerant vapors, which can displace oxygen and cause asphyxiation.
• Sécurité électrique : Ensure the power supply matches the unit's requirements (230V/50Hz). Do not operate with damaged cords or plugs. Avoid operating in wet conditions.
• Manipulation du réfrigérant : Be aware of the specific properties of the refrigerant being recovered. Some refrigerants are flammable or toxic.
• Sécurité sous pression : Do not exceed the maximum operating pressures. The unit features an automatic shutdown at 38.5 bar (558 psi).
• Cylindres : Use only approved recovery cylinders. Do not overfill recovery cylinders.
• Entretien: Coupez l'alimentation électrique avant toute opération de maintenance ou de nettoyage.

Installation

1. Déballage: Carefully remove the VRR24M-C unit from its packaging. Inspect for any shipping damage.
2. Placement: Place the unit on a stable, level surface in a well-ventilated area, away from direct sunlight or heat sources.
3. Connexion électrique : Connect the power cord to a grounded 230V/50Hz electrical outlet. Ensure the power switch on the unit is in the "OFF" position before connecting.
4. Connexions de tuyau :
   • Connect the appropriate hoses from the system to be recovered to the "IN" port of the recovery unit.
   • Connect a hose from the "OUT" port of the recovery unit to the recovery cylinder.
   • Assurez-vous que toutes les connexions sont bien serrées pour éviter les fuites.
5. Cylinder Preparation: Ensure the recovery cylinder is empty and has sufficient capacity for the refrigerant being recovered. Weigh the cylinder before and during recovery to prevent overfilling.

Mode d'emploi

The VRR24M-C unit offers different recovery modes for optimal performance.

Étapes générales de l'opération :

1. Ensure all hoses are correctly connected and valves are in the appropriate positions (refer to your system's specific recovery procedure).
2. Mettez l'interrupteur principal sur la position « MARCHE ».
3. Select the desired recovery mode using the operation knob (e.g., Gas, Liquid, Push/Pull).
4. Monitor the high and low-pressure gauges during the recovery process.
5. The unit will automatically shut off if the pressure exceeds 38.5 bar (558 psi).
6. Once recovery is complete, or the system pressure reaches the desired vacuum level, turn off the unit and close all valves.
7. Débranchez les tuyaux avec précaution, en faisant attention à toute pression résiduelle.

Recovery Efficiency (Approximate):

Note: Recovery efficiency may vary based on ambient temperature, system conditions, and refrigerant type.
