1. Quick instructions for sauna heater
1.1 Check before taking a sauna bath
1. that the condition of the sauna room is suitable for taking a sauna.
2. that doors and windows are closed
3. that the stones in the heater are recommended by the manufacturer, that the stones cover the heating
elements and that the stones are piled sparsely.
NOTE! Ceramic stones must not be used.
The sauna bath is comfortable at a temperature of about 70 °C.
Rearrange the unit's stones at least once a year and replace crumbled stones. This enhances air circulation between
the stones, extending the life of the heating elements.
Further information about sauna baths is available at: www.helo.fi

1.2 Using the heater's controls
The main switch is located in the base of the heater. The type plate shows the switch positions ( 0 I ).
See the instructions for the control unit in the "Using the Control Unit" section.
2. Information for users
Persons with reduced physical or mental capacity, disabilities, or little experience or knowledge of the equipment's
use (e.g. children), should only operate the equipment under supervision or according to instructions from the person
responsible for their safety.
Ensure that children do not play close to the sauna heater.
2.1 Sauna room
The walls and ceiling of the sauna room should be thermally well insulated. All surfaces that store heat, such as tiled
and plastered surfaces, must be insulated. Wood paneling is recommended for the sauna room's walls and ceiling. If
the sauna room's walls and ceiling have been clad with material that is highly heat-insulating (e.g. different types of
decorative stones, standard glass etc.), it must be remembered that this prolongs the sauna's heating-up time, even
though the sauna room is otherwise well insulated (see page 10, section 3 - Preparing for sauna heater installation).

7. A ventilation valve can also be installed here which is kept closed while the sauna is heating up and while bathing.
An inlet vent for fresh air can be positioned within area A. It must then be checked that the fresh air that enters does
not interfere with (cools down) the heater's thermostat that is located near the ceiling.
Area B is used for intake of fresh air if the sauna room does not have mechanical ventilation. If this is the case the
exhaust air valve must be positioned a minimum of 1 m higher than the inlet valve.
THE INTAKE VALVE FOR FRESH AIR MUST NOT BE POSITIONED WITHIN AREA C IF THE HEATER'S
CONTROL THERMOSTAT IS ALSO LOCATED WITHIN AREA C.

2.3 Heating the sauna
Before turning the heater on: ensure that the sauna room is suitable for taking a sauna bath. When heated for the first
time, the sauna heater may emit some odor. If this is the case, disconnect the sauna heater briefly, and air the room.
Then turn the sauna heater on again.
Turn the heater on at the control panel, where you can adjust the temperature and the time.
The heating of a sauna should be started roughly an hour before you plan to take a sauna bath, so that the stones
have time to heat up properly and the air warms up evenly in the sauna room.
Do not put any objects on the sauna heater. Do not dry clothes on the sauna heater or anywhere in its
vicinity.

2.4 Sauna stones
Good quality sauna stones should meet the following requirements:
- The stones must withstand heat and heat variation caused by vaporization of the water thrown on the
stones.
- The stones must be rinsed before use in order to avoid odor and dust.
- The stones must have an uneven surface so that the water ”sticks” on the surface of the stones and
evaporates more effectively.
- The stones must be sufficiently large (50–100 mm) to allow air to circulate between the stones. This
extends the life of the heating elements.
- The stones must be piled sparsely so that air circulates as effectively as possible between the stones. The
elements must not be wedged together nor wedged against the casing.
- The ventilation chambers on the sides of the stone compartment must not be filled with stones. Filled
ventilation chambers will lead to slower heat-up time of the sauna room and could also cause the heater to
overheat.
- The stones must be rearranged sufficiently often (at least once a year) so that small, crumbled stones can
be removed and replaced with larger new stones.
- The stones must be piled in such a way as to cover the elements. However, do not pile the stones too high
above the elements. Information about a suitable amount of stones is to be found in the table on page 12.
Any smaller stones in the package must not be placed on the heater.
- The guarantee does not cover defects caused by smaller and too tightly stacked stones that impede the air
circulation between the stones.
- Ceramic stones must not be used. Ceramic stones can cause damage to the heater that will not be covered
by the guarantee.

2.5 Disconnecting electrical heating, terminal #55 (output)
The electric heating disconnecting applies to homes with an electric heating system.
The sauna heater outputs 230-240V to terminal #55 when the heater is activated, i.e. this signal can be used to
(partly) deactivate house heating when the sauna heater switches on the current to the heating elements. May be
used in case the main fuses can´t take the full load of a sauna heater and electric space heaters.
2.6 If the sauna heater does not heat up
If the sauna heater does not heat up, check that
- the current is switched on
- the heater's main fuses are intact
- that the control panel is not displaying an error message. If the control panel displays an
error message read the operating instructions for the control panel.
