Maintenance Tips

• Re-stack & replace sauna stones (6–12 months): Use 5–10 cm stones and keep them loosely arranged for proper airflow and heat distribution.
• Avoid overpacking stones: Tight packing blocks airflow and can overheat elements, reducing efficiency and lifespan.
• Use clean water only: Do not use oils, salt, or treated water—this prevents residue buildup on heating elements.
• Inspect heating elements regularly: Ensure stones are not pressing directly on coils; damaged elements reduce performance.
• Wipe stainless steel exterior: Clean moisture and residue to prevent corrosion and maintain appearance.
• Check ventilation & safety clearances: Proper airflow and spacing improve heating efficiency and prevent overheating.
• Monitor control unit performance: This model requires an external controller—verify proper operation for consistent heating.
• Descale in hard water areas: Mineral buildup can reduce heating efficiency over time—clean periodically if needed.
