Heating Of The Sauna; Using The Heater; Throwing Water On Heated Stones; Water Quality Requirements - Harvia Spirit Instructions D'installation Et Mode D'emploi

Maintenance:
Due to large variation in temperature, the sauna stones disintegrate in use. Rearrange the stones at least once a year
or even more often if the sauna is in frequent use. At the same time, remove any pieces of stones from the bottom of
the heater and replace any disintegrated stones with new ones. By doing this, the heating capability of the heater stays
optimal and the risk of overheating is avoided. 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.

Heating of the Sauna

When operating the heater for the first time, both the heater and the stones emit smell. To remove the smell, the
sauna room needs to be efficiently ventilated. If the heater output is suitable for the sauna room, it will take about an
hour for a properly insulated sauna to reach the required bathing temperature. The sauna stones normally reach the
bathing temperature at the same time as the sauna room. A suitable temperature for the sauna room is about
65–80 °C.

Using the Heater

Before switching the heater on always check that no objects have been placed on top of the heater or
inside the given safety distance.
Heaters are controlled using a separate control unit. See the instructions for use of the selected control unit model.

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. Aim water only on the stones.
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.

Water quality requirements

The water to be thrown on the heated stones should meet the requirements of clean household water. Only
special aromas designed for sauna water may be used. Follow the instructions given on the package.
