Recommended Maintenance

• Filter Cleaning: Periodically clean or replace the air filters located in the ceiling assembly to maintain optimal airflow and cooling efficiency.

Always disconnect power to the unit before performing any maintenance.

• No Power: Check the RV's circuit breakers and fuses. Ensure the unit is properly plugged in or wired to the power source.
• Poor Cooling: Verify that air filters are clean and not obstructed. Ensure all windows and doors are closed to prevent warm air from entering the RV. Check for any obstructions around the outdoor unit.
• Unusual Noise: Inspect for loose components or debris in the fan area. If the noise persists, contact a qualified technician.
• Water Leaks: Ensure the RV is level. Check the drain pan and condensate drain lines for blockages.

For complex issues or repairs, contact a qualified RV service technician. Do not attempt to repair electrical or refrigerant components yourself.
