6. AIR EXCHANGE FOR THE STEAM ROOM:
- The air exchange in the steam room must be as efficient as possible, in order to guarantee sufficient
oxygen content and availability of fresh air. The air in the steam room should be changed 3-6 times
in an hour. It is recommended that the ventilation be realised in accordance with the HVAC designer’s plan
- The fresh air is directed through a ca. 100-mm diameter duct. The outlet duct should be larger in diameter
than the inlet duct. If the ventilation is mechanical, we recommend placing the inlet air valve in the ceiling
near the heater. Locate the temperature sensor at a sufficient distance from the inlet air valve!
- There must be a space of at least 1,000 mm between the temperature sensor and
the fresh air duct or 500 mm if the duct end can be turned.
- If the ventilation is natural, we recommend placing the inlet air valve on the side of the heater
or under it, either in the wall or in the floor.
- It is important to introduce fresh air, so that the air mixes with the air and the steam.
- The exiting air should be exhausted from near the floor as far as possible from the incoming air.
- The air exhaust valve may be located under the sauna benches.
- The exiting air may be directed out of the steam room through the washroom, for instance under the door.
There must be an approximately 100-150-wide slit between the door and the floor.
- If you provide your sauna with a separate drying valve, place it in the ceiling of the steam room.
(This valve shall be closed during the use of the sauna.)
The remaining power-on time is only 15 minutes, but you wish to continue enjoying
the sauna for longer than this
1. Depress the SET button -> the green LED flashes, the remaining power-on time will still be displayed.
2. Select the desired additional time by depressing the + button
3. Depress the SET button -> the red LED flashes.
4. Depress the SET button -> the heater will remain switched on for the time indicated on the display.
5. Note! After the desired period of time has been set, the green LED can be left flashing.
The heater will then automatically return to its normal operating mode within about 1 minute.
