This manual provides essential information for the operation and maintenance of the ACiQ Air Handler Unitary Ducted System. Key safety precautions include turning off the unit and disconnecting power before any cleaning or maintenance. Never use water hotter than 104°F (40°C) to clean the front panel, and do not use harsh chemicals or solvents.
Operating Modes
The system features four primary operating modes:
- FAN ONLY: Filters and circulates room air without changing the temperature.
- AUTO: Automatically cools or heats the room based on the user-selected set point. Recommended for single-zone applications only.
- HEATING: Heats and filters the room air. This is the system's priority mode.
- COOLING: Cools, dries, and filters the room air.
Note: Simultaneous heating and cooling is not allowed. If the power fails, the unit will automatically restart under the previous operating conditions once power is restored.
Care and Maintenance
Regular maintenance is crucial for system efficiency:
- Cleaning the Filter: Clean the air filter every two weeks. If the area is dusty, clean it more frequently. Replace the filter if it is heavily clogged.
- Cleaning Procedure: Remove the filter cover, remove the filter, and clean it by vacuuming or washing in warm water with mild detergent. Ensure the inlet side faces down when using water. Do not expose the filter to direct sunlight while drying.
- Pre-Season Inspection: Before frequent use, check for damaged wires, clean all filters, check for leaks, and ensure nothing is blocking the air inlets and outlets.
- Long Periods of Non-Use: Clean all filters, run the FAN function until the unit is completely dry, then turn off the unit and disconnect the power.
Energy Saving Recommendations
- Select a comfortable thermostat setting and avoid frequent adjustments.
- Keep the filter clean to maintain efficiency.
- Use drapes or curtains to block direct sunlight on hot days.
- Use the TIMER function to limit run time.
- Keep doors and windows closed while the system is operating.
- Do not obstruct the air intake or outlet.
Troubleshooting
If the unit does not turn on, note that it has a 3-minute protection feature to prevent overloading; wait three minutes before attempting to restart. If the unit emits white mist, this is often due to a large temperature difference in humid regions or the defrosting process. If issues persist, contact an authorized dealer or service center.
