Example 1.
You want to go jogging and have a sauna bath after
that. The estimated duration of your run is 5 hours.
Turn the timer clockwise over the scale 0–1 to the pre-
set section (scale 1–8) at number 4.
The timer will start, and after four hours, the heater
will come on. Because it takes about one hour for the
sauna to be heated, it will be warm and ready for
bathing after about 5 hours, that is, when you come
back from your run.
Example 2.
If you want to bathe ”immediately” and thus do not
want to use the pre-set timing, the timer must be set
to the desired point in the section 0–1. Then, the
heater will be switched immediately on and the
sauna will be ready for bathing after about one hour.
Switch the heater off immediately after bathing
and check that the sauna rocks are dry. Sometimes
it may be advisable to leave the heater on for a while
to let the wooden parts of the sauna dry properly.
NOTE! It is absolutely necessary to check that the
timer has cut off the supply of the elements after the
set time.
1.3.2. Thermostat
The temperature is adjusted by the thermostat to a
position between minimum and maximum. See
figure 2. The correct position of the thermostat
switch is found by experimenting.
Begin experimenting at the maximum position (far
right) to find how quickly the sauna room and rocks
can be heated to the desired temperature. If, during
bathing, the temperature seems to be becoming too
high, turn it down a little by turning the switch
counter-clockwise. It must be noted that even a
small difference within the maximum section will
change the temperature of the sauna considerably.
1.3.3. Overheating limiter
Each heater i equipped with a overheating limiter
which is a safety device.
If, for some reason, the temperature of the sauna
room becomes too high, the overheating limiter will
permanently cut off the supply of the resistances.
The overheating limiter cannot be reset to the
position allowing electricity until the heater has
cooled down. The overheating limiter is reset by
pressing the reset button, which is located in bottom
of heater. See figure 3.
To reset the overheating limiter, locate the reset
button and push upward until contactor kicks in. If
reset button continues to trip, contact a qualified
service person.
Do not remove the overheating limiter bulb. See
spare parts no. 2.
Prior to pressing the button, the cause of the fault
must be found:
• are the rocks crumbled and pressed together?
• has the heater been on for a long time while
unused?
• has the heater been banged or shaken?
1.4. Throwing Water on Heated Stones
The air in the sauna room becomes dry when
warmed up. Therefore, it is necessary to throw
water on the heated rocks to reach a suitable level
of humidity in the sauna.
The humidity of the air in the sauna room is controlled
by the amount of water thrown on the rocks. A correct
level of humidity makes the bather’s skin sweat and
makes breathing easy. By throwing water on the rocks
with a small ladle, the bather should feel the effect of
air humidity on his skin.Bothtoohigh a temperature and
air humidity will give an unpleasant feeling.
Staying in the hot sauna for long periods of time
makes the body temperature rise, which may be
dangerous.
The maximum volume of the ladle is 2 decilitres.
The amount of water thrown on the rocks at a time
should not exceed 2 dl, because if an excessive
amount of water is poured on the rocks, only part of
it will evaporate and the rest may splash as boiling
hot water on the bathers.
Never throw water on the rocks when there are
people near the heater, because hot steam may burn
their skin.
1.4.1. Sauna Water
The water to be thrown on the heated rocks should
meet the requirements of clean household water.
The factors essentially affecting the quality of water
include the following:
• humuos content (colour, taste, precipitates);
• recommended content less than 12 mg/litre.
• iron content (colour, smell, taste, precipitates);
• recommended content less than 0,2 mg/litre.
• hardness – the most important substances are
manganese (Mn) and calcium (Ca); recommended
• content of manganese 0.05 mg/litre, calcium
less than 100 mg/litre.
Calcareous water leaves a white, sticky layer on
the rocks and metal surfaces of the heater.
Calcification of the rocks deteriorates the heating
properties.
Ferrous water leaves a rusty layer on the surface
of the heater and elements, and causes corrosion.
The use of humous, chlorinated water and
seawater is forbidden.
Only special perfumes designed for sauna water
may be used. Follow the instructions given on the
package.
