by the use of stones not recommended by the plant.
Neither does the guarantee cover any faults caused
by disintegrated or too small stones blocking the
heater ventilation.
No such objects or devices should be placed inside
the heater stone space or near the heater that could
change the amount or direction of the air flowing
through the heater, thus causing the resistance tem-
perature to rise too high, which may set the wall
surfaces on fire!
1.4.1. Repositioning and Replacing of Stones
It is recommended that the stones be repositioned
every time the stone level has stopped descending
or no less than once a year. Depending on the fre-
quency of use, the stones should be replaced with
new ones at intervals of every 2–3 years. When re-
positioning or replacing the stones, the small pieces
of stone should be removed from the bottom of
the heater and the stones that have become "soft"
should be replaced. The heater should be warmed
up to remove moisture from the new stones. See
Point 1.5. "Setting the heater in standby mode and
heating it for the first time".
1.5. Setting the Heater in Standby Mode and
Heating It for the First Time
The electronics of the heater are switched on and
off using the small electric switch with a swing
mechanism I in front of the heater (fig. 1). When
6
x 4
the switch is in the ON position, the indicator light
under the I/O button burns as an indication of the
standby mode. In standby mode, the heater heating
elements do not carry current. The person installing
the heater sets it in standby mode when making the
electrical connections.
When the heater is switched on for the first time
the heater and insulations of the heater emit odour
for several days (about 2–3 days). Warming heater
also emphasizes the odours. In the first heating
times we recommend to set the standby mode to a
maximum for several days (adjust LO temperature
by pressing the + button to the maximum, display
shows IIIIII). After this the temperature of standby
mode can be adjusted to the recommended operat-
ing level (display shows III).
Also the stones emit odour in the first heating
time. To remove this, the sauna room needs to be
efficiently ventilated. These actions should also be
taken when stones are rearranged or added to the
heater.
1.5.1. Standby Mode
To switch the heater on, press the I/0 button. To
indicate that current has been connected to the
heating elements, the display shows the message
LO (standby power). In addition, indicator light 6
(fig. 2) is lit up. The temperature of the stone space
can be set to a maximum of 500 degrees Fahrenheit
(260 degrees Celsius) by pressing the + button 5
(fig. 2). The minus button 4 (fig. 2) is used to lower
the temperature if it has been set too high.
The electric power consumption of the heater can
be monitored using indicator lamp 8 (fig. 2). See the
section "Display screen."
1.5.2. Full Capacity
To switch on to full capacity, press the operating
button 3 (fig. 2) once. The display screen 1 (fig. 2)
indicates that the HI state (= full heater capacity) is
in use. In the HI state, the stone space temperature
increases towards the set value of 500 °F (260
Full capacity is switched on for only one hour at a
time, after which the heater automatically switches
to the LO state with indicator light 6 burning (fig
2). After initial heating, the heater cover must be
closed. If the stone chamber seems to emit odours,
the cover can be left open for a while as the heater
operates at full capacity (HI).
To get a really good bath, wait for one full day
to allow the heat to distribute itself evenly in the
closed stone space.
1.6 Heating the Sauna Room for a Bath
After the heater has been properly pre-heated, the
stones are ready for a bath at any time. However,
a certain amount of time is needed to raise the
temperature of the sauna room to a pleasant level.
The size, wall materials and thermal insulation of the
sauna room play a significant part in this respect.
When the heater cover 1 (fig. 1) is opened, the air
flowing through the hot stones and the heating ele-
ments begins to heat up the room. To ensure that
the thermal energy stored in standby mode remains
in the heater stones despite the cooling effect of air
currents and the water thrown on the stones, the
heater power should be switched on during bathing
using the operating button 3 (fig. 2). "HI" will be
C).
