Maintenance Tips

• Re-stack sauna stones regularly to ensure proper airflow and prevent overheating of heating elements.
• Replace cracked or crumbling stones to maintain efficient heat transfer and steam quality.
• Keep stone filling loose—do not tightly pack, as restricted airflow can damage elements.
• Remove dust and mineral residue from the stone compartment during periodic servicing.
• Inspect heating elements during maintenance for scaling or wear (always power off first).
• Wipe stainless steel exterior with a soft cloth after cooling to prevent stains and corrosion.
• Ensure control unit and electrical connections remain dry and are checked periodically by a qualified electrician.
• Maintain clear ventilation around the heater for safe, continuous-duty operation (designed for commercial use).
• Schedule annual professional inspection of wiring, contacts, and safety systems for long-term reliability.
