6. Maintenance

Regular maintenance ensures the longevity and efficient operation of your ROVSUN Mini Split System.

Filter Cleaning:

• Frequency: Clean the air filters in the indoor units every 2-4 weeks, or more frequently if the unit is used heavily or in dusty environments.
• Procedure: Open the front panel of the indoor unit, remove the filters, and wash them with lukewarm water and mild detergent. Rinse thoroughly and allow them to dry completely before reinserting.

Outdoor Unit Care:

• Clear Debris: Periodically check the outdoor unit for leaves, dirt, and other debris that may obstruct airflow. Clear any blockages.
• Coil Cleaning: The outdoor coil should be cleaned annually by a qualified technician to remove accumulated dirt and grime, which can reduce efficiency.

Seasonal Maintenance:

• Pre-Season Check: Before the start of cooling or heating seasons, it is advisable to have a professional HVAC technician inspect the system.
• Drainage: Ensure the condensate drain lines are clear and free of blockages to prevent water leakage.

7. Troubleshooting

Before contacting customer support, please refer to the following common issues and solutions.

Common Issues and Solutions:

• Unit Not Turning On:
  - Check if the power supply is connected and the circuit breaker has not tripped.
  - Ensure batteries in the remote control are functional.
• Insufficient Cooling/Heating:
  - Verify that the correct operating mode is selected.
  - Clean the air filters in the indoor units.
  - Check for obstructions around the outdoor unit.
  - Ensure windows and doors are closed.
  - The system's maximum working capacity will not exceed the outdoor unit's rated BTU.
• Water Leakage from Indoor Unit:
  - Check if the drain hose is clogged or improperly installed.
  - Ensure the indoor unit is level.
• Unusual Noises:
  - A slight gurgling sound is normal due to refrigerant flow.
  - If loud or unusual noises occur, contact a qualified technician.
• Remote Control Not Working:
  - Replace batteries.
  - Ensure there are no obstructions between the remote and the indoor unit.
• Indoor units cannot be set to different modes simultaneously (cooling/dehumidifying VS heating) as this will cause mode conflict.

If the problem persists after attempting these solutions, please contact ROVSUN customer support or a qualified HVAC technician.
