7. Troubleshooting

If you encounter issues with your system, consider the following common points before contacting technical support:

• No Power: Check circuit breakers and ensure the unit is properly plugged in.
• Insufficient Cooling/Heating: Verify that air filters are clean, doors and windows are closed, and the thermostat setting is appropriate for the desired temperature.
• Thermostat Accuracy: Note that the displayed temperature on the thermostat may not always perfectly match the exact room temperature. Adjust settings based on comfort rather than precise numerical values.
• Unusual Noises: Minor creaking sounds can occur during heating mode due to thermal expansion. If loud or persistent noises occur, contact support.
• Water Leakage: Check the drainage line for kinks or blockages. Ensure the indoor unit is level.

For complex issues or if troubleshooting steps do not resolve the problem, contact Cooper&Hunter technical support.
