❓ Frequently Asked Questions (FAQ)
| Question | Answer |
| Why are there two different LRA values for QP407? | LG provides different internal configurations (motor types or winding) for the QP407 shell. A lower LRA (52.5A) usually indicates a higher-efficiency motor design (like a PSC motor), which is easier on the electrical system during startup. |
| What does ‘LRA 75’ versus ‘LRA 52.5’ mean for system compatibility? | The LRA (Locked Rotor Amps) value is critical for selecting compatible starting relays, contactors, and electrical fuses. You must match the LRA of the replacement unit to the original specification. |
| Is this compressor 3-phase? | No. This model is explicitly rated for single-phase (1PH), 220-240V / 50Hz power. |
| What is the typical application for 24,000 BTU/hr? | This capacity is equivalent to a high-capacity system, often referred to as a 2 Ton unit, suitable for large living areas, open-plan offices, or light-commercial cooling. |
