3. Setup and Installation

Important: Installation of this HVAC system must be performed by a qualified and certified HVAC technician. Improper installation can lead to system malfunction, reduced efficiency, and void the product warranty. Refer to local codes and regulations for specific installation requirements.

3.1 Site Selection

• The outdoor unit should be placed on a level, stable surface, away from direct sunlight and obstructions that could impede airflow.
• The indoor air handler can be installed in upflow, horizontal right, or horizontal left configurations. For downflow installation, an optional downflow kit must be purchased separately.

3.2 Electrical Connections

Ensure all electrical wiring complies with national and local electrical codes. The system operates on 120 Volts. A dedicated circuit may be required.

3.3 Refrigerant Lines

The system uses R-32 refrigerant and is pre-charged for 15 feet of line set. Proper evacuation and charging procedures are critical for optimal performance and must be performed by a certified technician.

4. Operating Instructions

Once installed, your Goodman split system is controlled by a thermostat (sold separately). Familiarize yourself with your thermostat's specific operating instructions.

4.1 Cooling Mode

1. Set your thermostat to "Cool" mode.
2. Adjust the desired temperature. The system will activate to cool your home to the set temperature.
3. Ensure all windows and doors are closed to maintain cooling efficiency.

4.2 Fan Operation

The fan can be set to "Auto" or "On". In "Auto" mode, the fan runs only when the system is actively cooling. In "On" mode, the fan runs continuously to circulate air.

5. Maintenance

Regular maintenance is crucial for the efficiency and longevity of your HVAC system. Always turn off power to the unit before performing any maintenance.

5.1 Air Filter Replacement

Check and replace the air filter in your indoor air handler every 1-3 months, or more frequently if you have pets or allergies. A dirty filter restricts airflow and reduces efficiency.

5.2 Outdoor Unit Cleaning

Keep the outdoor condenser unit free from debris, leaves, and grass clippings. Periodically rinse the coils with a garden hose to remove dirt buildup. Ensure the area around the unit has at least 2 feet of clear space for proper airflow.

5.3 Professional Servicing

It is recommended to have your system professionally inspected and serviced annually by a qualified HVAC technician. This ensures optimal performance, identifies potential issues early, and maintains warranty validity.

6. Troubleshooting

Before calling for service, check these common issues:

• No Cooling:
  • Check thermostat settings (set to "Cool" and desired temperature).
  • Ensure circuit breakers for both indoor and outdoor units are not tripped.
  • Verify the air filter is clean and not blocked.
• Weak Airflow:
  • Check for a dirty air filter.
  • Ensure supply and return vents are open and unobstructed.
• Unusual Noises:
  • Rattling or vibrating sounds may indicate loose panels or debris.
  • Hissing sounds could indicate a refrigerant leak (contact a technician immediately).

For complex issues or refrigerant concerns, contact a qualified HVAC professional.
