9. REGULAR UPKEEP AND MAINTENANCE

All maintenance operations requiring special skills must be carried out by a trained
professional.

9.1. Sauna heater stones

• Due to intense thermal cycling, the sauna heater stones will gradually deteriorate and crumble during
use. Replace the stones at least once a year, or more often if the sauna is used very frequently.
• At the same time, remove any accumulated stone debris and replace any broken stones. This will en-
sure that the sauna heater's steaming properties are maintained and there is no risk of overheating.
• Check occasionally whether the stone level has become lower. Make sure that the heating elements
do not become visible over time. The stone level is likely to become lower in about two months after
the stones have been placed.
