Q: What accessories are required for installing the KUSAC091A?

A: The following components are needed for a complete installation:

• Line set: Transfers refrigerant between indoor and outdoor units
• Drain tubing: Removes condensate from the indoor unit
• Connecting wire: Supplies power and communication between units
• Disconnect box with whip kit: Ensures a safe electrical connection to the main power supply
• Condenser pad or wall bracket: Elevates and supports the outdoor unit for proper airflow and protection

Q: Can I install the KUSAC091A myself?

A: No. Installation must be performed by a licensed HVAC professional. The process involves high-voltage electrical work and refrigerant handling, which pose serious safety risks if done incorrectly.

Q: Where should the outdoor unit be installed?

A: The unit should be placed on a level surface, such as a plastic pad, or mounted on a secure wall bracket. To ensure proper performance:

• Allow for adequate ventilation
• Avoid installing in enclosed areas like small balconies with closed windows
• Maintain clear airflow around the unit

Q: Why is the outdoor unit making noise?

A: The KUSAC091A is built for quiet operation, but some operational noise is normal (e.g., fan hum, refrigerant flow). If you hear unusual or loud noises, LG provides audio samples on its support website to help identify specific sounds and their causes.

Q: What does error code CH61 mean?

A: Error code CH61 indicates that the outdoor unit’s heat exchanger is overheating. This is often caused by restricted airflow, so check the area around the unit for any obstructions or poor ventilation.
