This manual provides essential information for the safe operation and maintenance of your ACiQ Ducted Air Handler. Always disconnect the power supply before performing any cleaning or maintenance. Ensure that air inlets and outlets are not blocked and that filters are cleaned regularly to maintain efficiency.
Safety Precautions
To prevent injury or property damage, follow these safety guidelines:
- Electrical Safety: Always disconnect power before cleaning. Use only the specified power cord. Ensure the unit is properly grounded. If the power cord is damaged, it must be replaced by a qualified professional.
- Operational Safety: Do not insert objects into air inlets or outlets. Do not use flammable sprays near the unit. Do not operate in wet rooms like bathrooms.
- Installation: Installation must be performed by a licensed professional HVAC installer. Ensure the location can support the unit's weight.
Operating Conditions
For optimal performance, operate the system within the following temperature ranges:
- Cool Mode: Room temperature 16°C - 32°C (60°F - 90°F).
- Heat Mode: Room temperature 0°C - 30°C (32°F - 86°F).
- Dry Mode: Room temperature 10°C - 32°C (50°F - 90°F).
Note: If the outdoor temperature is below 0°C (32°F) for units with an auxiliary electric heater, keep the unit powered at all times to prevent damage.
Care and Maintenance
Regular maintenance is crucial for the longevity of your unit:
- Cleaning: Use a soft, dry cloth for cleaning. Do not use water hotter than 40°C (104°F), volatile cleaners, or combustible agents.
- Filters: Replace or clean air filters every 30 to 90 days, depending on the MERV rating and thickness.
- Long-term Storage: If the unit will be unused for an extended period, clean all filters and run the FAN function until the unit is completely dry.
Troubleshooting
Before contacting a service provider, check the following common issues:
- Unit won't turn on: Check if the 3-minute protection feature is active. Wait three minutes before restarting.
- White mist: This is normal in humid regions due to temperature differences.
- Noises: Hissing sounds are normal refrigerant flow. Squeaking may occur due to plastic expansion/contraction.
- Poor Performance: Check for dirty filters, blocked inlets/outlets, or open doors/windows.
