2. Installation Guide for the MSZ-GL06NA

Proper installation is crucial for performance and longevity. While professional installation is recommended, understanding the process helps supervise and troubleshoot.

Step 1: Pre-Installation Checks

• Verify that the electrical supply matches the unit’s requirements (208- 230V, 60Hz).

• Ensure the wall can support the indoor unit’s weight (typically 20-30 lbs).

• Check refrigerant line length (varies by model but usually ≤ 82 ft).

Step 2: Mounting the Indoor Unit

1. Select a location – Avoid direct sunlight, heat sources, and areas with poor airflow.

2. Install the mounting plate – Use a level to ensure it’s straight.

3. Drill holes for piping – Follow the Installation Manual for exact measurements 14.

Step 3: Connecting Refrigerant Lines & Wiring

• Use flare fittings for leak-proof refrigerant connections.

• Route drain tubing with a slight downward slope to prevent water accumulation.

• Connect control wiring as per the MSZ-GL06NA wiring diagram 4.

Step 4: Final Checks & Testing

• Perform a vacuum test on refrigerant lines.

• Power on the unit and test the cooling/heating functions.

• Verify no abnormal noises or leaks.

📌 Pro Tip: Refer to the official Mitsubishi installation manual for model-specific details 15.

3. Operating the MSZ-GL06NA for Maximum Efficiency

Remote Control Functions
