Tip: Label all wires during installation for easier future service. Ensure wire gauge meets local code and unit requirements.

Maintenance

Regular maintenance ensures efficiency and longevity.

1. Outdoor Unit: Keep area clear of debris, leaves, and vegetation (minimum 2 ft clearance). Gently clean coil with water hose (power off). Straighten any bent fins.
2. Indoor Unit: Replace air filter regularly (check monthly). Schedule professional annual maintenance.
3. Professional Service: Annual inspection should include: check refrigerant charge, inspect electrical connections, clean coils, check condensate drain, verify system operation and safety controls.
4. Winterization: In cold climates, consider a protective cover (ensure it does not trap moisture).

WARNING! Always turn off power at the disconnect before performing any cleaning or maintenance around the outdoor unit. Do not use a pressure washer on the coil.
