Installation & Product Tips

  • Mounting Height: Install the air handler 7–8 feet above the floor for optimal airflow distribution. Avoid mounting directly above doors or windows.
  • Line Set Routing: Plan your line set route before mounting. The line set must slope slightly toward the outdoor unit for proper condensate drainage.
  • Electrical Requirements: This air handler requires a dedicated circuit. Consult a licensed electrician if you are unsure of your home's electrical capacity.
  • Wi-Fi Setup: The built-in Wi-Fi module connects to 2.4 GHz networks only. Have your network password ready during setup.
  • Filter Maintenance: Clean or replace the air filter every 4–6 weeks during heavy use to maintain efficiency and air quality.
