Maintenance Tips

• Clean washable air filter regularly – Rinse every 1–3 months and replace if damaged to maintain airflow and efficiency.
• Keep wall vents unobstructed – Ensure intake and discharge grilles are clear for proper air circulation (critical for in-wall units).
• Check drain line & plumbing connection – Inspect for clogs or leaks since the unit drains directly into a hub drain/plumbing system.
• Wipe intake/exhaust areas – Prevent dust buildup that can reduce performance and strain the blower.
• Monitor humidity settings – Verify onboard digital control is set correctly for consistent moisture removal.
• Operate within recommended temperature range – Ideal range is ~49°F–95°F for optimal efficiency and to avoid freezing issues.
• Inspect for unusual noise or reduced output – Early detection helps prevent costly internal repairs.
• Annual professional check-up – Recommended for sealed system, coils, and electrical components (since in-wall units are less accessible).
