Maintenance Tips

• Keep heater stones clean, dry, and properly stacked; re-stack regularly for optimal airflow and even heat distribution.
• Replace cracked or crumbling stones to maintain efficient steam generation and protect internal components.
• Periodically vacuum or gently clean the stone compartment to remove dust and mineral residue buildup.
• Ensure air intake and outlet paths (climate equalizer system) remain unobstructed for proper air mixing performance.
• Check heating elements during stone maintenance for scaling or damage (avoid direct contact when hot).
• Clean exterior stainless steel with a soft damp cloth after cooling to prevent water stains and corrosion.
• Inspect electrical connections and control sensor placement during scheduled servicing (power off before checking).
• Maintain proper ventilation in the sauna room to support consistent temperature regulation and prevent overheating.
• Schedule annual professional inspection for wiring, sensors, and safety systems to ensure long-term reliability
