4. Setup and Installation
The Goodman e-Series is a split-system air conditioner requiring professional installation. It consists of an indoor unit and an outdoor unit.
- Site Selection: Choose appropriate locations for both indoor and outdoor units, ensuring adequate space for airflow and maintenance. The indoor unit should be placed to allow for optimal air distribution, and the outdoor unit should be on a stable, level surface away from obstructions.
- Electrical Requirements: Ensure a dedicated 230V power supply is available and properly wired according to local electrical codes.
- Refrigerant Piping: The indoor and outdoor units are connected via refrigerant lines. This process requires specialized tools and expertise to ensure proper sealing and charging.
- Drainage: The indoor unit produces condensation that must be properly drained. Ensure the drain line is correctly installed and sloped to prevent water leakage.
- Vacuuming and Charging: The refrigerant system must be vacuumed to remove air and moisture, then charged with the correct amount of refrigerant.
