Setting the Temperaturer
The purpose of the thermostat is to keep the temperature in the sauna room on a desired level. By
experimenting, you can find the setting that suits you best.
Throwing Water on Heated Stones
The air in the sauna room becomes dry when warmed up. Therefore, it is necessary to throw water on the
heated stones to reach a suitable level of humidity in the sauna. The effect of heat and steam on people
varies – by experimenting, you can find the levels of temperature and humidity that suit you best.
NOTE! The maximum volume of the ladle is 0.2 litres. If an excessive amount of water is poured on the
stones, only part of it will evaporate and the rest may splash as boiling hot water on the bathers. Never
throw water on the stones when there are people near the heater, because hot steam may burn their
skin.
NOTE! The water to be thrown on the heated stones should meet the requirements of clean household
water (table 1). Only special aromas designed for sauna water may be used. Follow the instructions
given on the package.
