SAUNA STONES
Should be washed before use. Fill the stone compartment from bottom to top with the large stones at the bottom
The heating elements should be covered by the small stones, however, never force the stones between the
elements
VENTILATION
Since a sauna bath should be as pleasant and relaxing as possible, proper ventilation is essential.
The air circulation in a family sauna should be recycled six times per hour during a sauna bath. The fresh air inlet
vent should be below the sauna heater and have a diameter of 60 mm.
The outlet should be as far from the inlet as possible and placed diagonally across the sauna from the inlet hole.
The outlet should be twice as big as the inlet and approx. 600 mm above the floor.
CONTROLLING THE TEMPERATURE WITH CONTROL BOX
The desired temperature for the sauna is chosen on the thermostat. The heater is switched on by turning the timer.
The signal light on the control box lights up to inform that the heater is "ON".
After bathing the heater is turned off by turnin the timer to 0-setting. The signal light goes out to inform that the
heater is "OFF".
Should you forget to switch off the heater, it will automatically switch off.
The thermostat can be programmed to turn off at a desired temperature and needs to be turned off only when the
temperature in the sauna is altered.
LIMIT CONTROL
If the temperature in the sauna should rise too high (for example due to a thermostat fault) the limit switch in the
sensor will turn off the power. When the fault has been rectified the switch may be reset.
TIMER
The timer is the main on/off switch for the controlpanel. To switch on, turn knob clockwise: The Scale provides first
a 1-4hr working band, then a 1-8hr preset band which delays the switch on time. The pilot light shows when the
heater is on.
