Maintenance Tips
-
Replace Air Filters Regularly: Inspect monthly and replace every 1–3 months to maintain airflow and protect the blower and coil.
-
Keep Vents & Registers Clear: Ensure supply and return vents are unobstructed for even airflow and heating.
-
Inspect Condensate Drain: Check the drain line and pan for clogs or leaks to prevent water damage and mold growth.
-
Clean Around the Unit: Remove dust and debris from the wall-mount area to allow proper airflow.
-
Check Electrical Connections: Ensure 230V power supply wiring and heater connections are secure and corrosion-free.
-
Monitor Blower & Heater Operation: Listen for unusual noises; verify the 8 kW heater engages properly when needed.
-
Schedule Annual Professional Service: Have a licensed HVAC technician inspect the blower motor, heating element, coil, and system controls yearly for optimal performance.
