5. Operating Instructions

Your Goodman GPHH33641 heat pump provides both heating and cooling functions. Operation is typically controlled via a compatible thermostat (not included). Refer to your thermostat's manual for specific programming instructions.

• Cooling Mode: Set your thermostat to "Cool" and select your desired temperature. The unit will operate to lower the indoor temperature.
• Heating Mode: Set your thermostat to "Heat" and select your desired temperature. The unit will operate to raise the indoor temperature.
• Fan Mode: The fan can be set to "Auto" (runs only when heating/cooling) or "On" (runs continuously).
• Energy Efficiency: To maximize energy savings, avoid frequent thermostat adjustments. Consider using programmable thermostat features to set back temperatures when away or asleep.

6. Maintenance

Regular maintenance is essential for the longevity and efficient operation of your heat pump. Some tasks can be performed by the homeowner, while others require a qualified HVAC technician.

Homeowner Maintenance:

• Air Filter Replacement: Check and replace or clean the air filter monthly, or more frequently if the unit is in constant use or in dusty environments. A dirty filter restricts airflow and reduces efficiency.
• Clear Debris: Keep the area around the outdoor unit clear of leaves, grass clippings, and other debris to ensure proper airflow to the condenser coil.
• Clean Coils (Exterior): Gently rinse the exterior of the outdoor coil with a garden hose to remove dirt and dust. Do not use high-pressure washers.

Professional Maintenance (Annual):

• Coil Cleaning: Thorough cleaning of indoor and outdoor coils.
• Refrigerant Level Check: Verify proper refrigerant charge.
• Electrical Component Inspection: Check wiring, connections, and capacitor.
• Blower Motor and Fan Inspection: Lubrication (if applicable) and cleaning.
• Drain Line Cleaning: Ensure the condensate drain is clear and free of blockages.
