Check Before You Order
- Verify the existing compressor's model number (NL7.3MF) and power supply (220-240V/50Hz) against your unit's data plate.
- Confirm the refrigerant type is R134a or R513A as specified on the unit.
- Measure the suction, discharge, and process connector diameters on your existing unit to ensure they match these specifications.
- Check the overall height and weight to ensure it fits the available space and mounting hardware.
Fitting Notes
- Installation and handling of R134a and R513A refrigerants require a current ARCtick licence.
- Electrical connections and testing must be carried out by a licensed electrician.
- Ensure the refrigeration system is fully discharged and evacuated to industry standards before compressor replacement.
- Apply appropriate torque settings to all brazed or flared connection points to prevent refrigerant leaks.
- Confirm correct POE oil charge and type before commissioning the system.
