Sauna

First heat-up: run the sauna empty, with ventilation open, for 30 to 60 minutes — this releases manufacturing moisture and odors (a slight new-wood smell is normal and fades away). Daily use: set the temperature on the controller — 70-90 °C for a traditional sauna, 45-65 °C for an infrared one. Let it preheat, then step in. Pour water (löyly) with the ladle, in small amounts. Safety: never cover the heater, never place anything on it, and never use the sauna without the stones in place.

After each session: leave doors and vents open so the wood dries, and wipe the benches and floor. Cleaning: warm water and a soft brush, no harsh products. Never use bleach, solvents or varnish inside — the wood must stay untreated so it can breathe. A stubborn stain comes off with light sanding along the grain. Protection: always sit on a towel on the bench (perspiration). For intensive use, a sauna-grade paraffin oil treatment is possible on the benches only.

Layout: stack the stones loosely, so air and steam can circulate between them; do not overload the heater. Checks: inspect the stones 1-2 times a year (more often with intensive use) and replace any that crack or crumble — broken stones block airflow and make the heating element overheat. Safety: never run the heater without stones, never cover it, and pour water with the ladle (never a large amount at once).

Good ventilation ensures healthy air and even heat. Low air inlet near the heater (fresh air warms up on contact), low extraction on the opposite side to sweep the whole cabin. Adjust the outlet grille opening to your liking. For intensive use (clubs, high rotation), aim for 6 to 8 air changes per hour with direct exhaust to the outside, never recirculated.

Heater on a dedicated line (three-phase depending on power), emergency stop wired directly to the panel in public facilities. Details depend on cabin volume.
