Installation and User Manual Rocher Pure
2.3. Ceiling installation of the sensor
In ceiling installation, a 5-mm hole must be drilled to the sensor case to
allow any condensed water to drain.
Do not spray water directly towards the sensor or splash water at it with
a sauna scoop.
2.4. Installing the Extra NTC sensor
The additional OLET 31 sensor is connected to the Ext NTC connector on the RJ10 circuit board. For more details, refer to
the switch diagram. The additional sensor is installed on the sauna room wall no more than 500 mm from the ceiling. Once
the additional sensor has been connected to the circuit board, it is automatically activated. This means that the tempera-
ture shown on the control panel is measured by the additional sensor.
The primary sensor installed above the sauna heater only has the limiter circuit that limits the maximum temperature to
110 °C. Even if the temperature is set to 110 °C on the control panel, the maximum temperature that can be shown on the
panel is approximately 90 °C, as the primary sensor above the heater limits the maximum temperature to 110 °C. Depend-
ing on individual preferences, the temperature of a sauna room is typically set between 70 and 80 °C.
2.5. Sauna heater stones
Quality stones meet the following requirements:
- Sauna stones should withstand heat and heat variation caused by vaporisation of the water thrown on the
stones.
- Stones should be rinsed before use in order to avoid odour and dust.
- Sauna stones should have an uneven surface to supply a larger surface for the water to evaporate from.
- Sauna stones should be large enough, measuring about 100–150 mm to allow good ventilation between the stones.
This extends the useful life of the heating elements.
- Sauna stones should be piled sparsely in order to enhance ventilation between the stones. Do not bend the heating
elements together or against the frame.
- Rearrange the stones regularly (at least once a year) and replace
small and broken stones with new, larger stones.
- Empty the stone compartment regularly, at least once a year in private
use, remove small and broken stones and replace them with new ones.
- In commercial use this operation must be performed at least every
second month.
- Stones are piled so that they cover the heating elements. Do not,
however, pile a large heap of stones on the heating elements. For
a sufficient amount of stones refer to Table 1 on page 6. Any small
stones in the package of stones must not be piled on the sauna heater.
- The warranty does not cover defects resulting from poor ventilation caused by small and tightly packed stones.
- Structural clay tiles are not allowed. They may cause damage to the sauna heater that will not be covered by the
warranty.
- Do not use soapstone as sauna rocks. Any damages resulting from this will not be covered by the stove
warranty.
- Do not use lava stone as sauna rocks. Any damages resulting from this will not be covered by the stove
warranty.
- DO NOT USE THE HEATER WITHOUT STONES.
