5.5 Using Water on Stones
Once the sauna stones are hot, you can gently ladle small amounts of water onto them to create steam and increase humidity. Use only clean tap water. Do not pour excessive amounts of water at once, and avoid pouring water directly onto the heating elements.
6. Maintenance
6.1 Cleaning
Ensure the heater is completely cool and disconnected from the power supply before cleaning. Wipe the exterior surfaces with a damp cloth. Do not use abrasive cleaners or solvents.
6.2 Stone Replacement
Sauna stones should be inspected regularly (at least once a year, or more frequently with heavy use) and replaced as needed. Over time, stones can crumble and lose their heat retention properties. Replace any cracked or disintegrated stones to ensure optimal performance and safety.
6.3 Regular Inspections
Periodically check the electrical connections for any signs of wear or damage. Ensure the heater's mounting is secure. If any issues are observed, contact a qualified technician.
