1.1. Check before taking a sauna bath
1. The sauna room is suitable for taking a sauna bath.
2. The door and the window are closed.
3. The sauna heater is topped with stones that comply with the manufacturer's
recommendations, the heating elements are covered with stones, and the stones
are piled sparsely.
The main switch is marked with a 0 –1 sticker.
1.2. Sauna room
The walls and ceiling of a sauna room should be thermally well insulated. All
surfaces that store heat, such as tiled and plastered surfaces must be insulated. It is
recommended to use wooden panel cladding inside the sauna room. If there are
heat storage elements in the sauna room, such as decorative stone, glass etc., note
that these elements may extend the pre-heating period even though the sauna room
is otherwise well insulated (see page 4, section 1. Preparing for sauna heater
installation).
1.3. Operation of the sauna heater controls
This appliance may not be used by children aged less than eight years, by persons
with reduced physical, sensory or mental capabilities, or by persons lacking
experience and knowledge regarding its operation only if such have been given
instructions on the safe use of the device and the risks involved. Children must not
be allowed to play with the appliance or to clean and service it without supervision.
(7.12 EN 60335-1:2012)
1.4. Operation of the sauna heater controls
Refer to the specific control panel operating instructions.
Rearrange the sauna stones at least once a year and replace any weathered
stones. This enhances air circulation between the stones, which extends the useful
life of the thermal resistors.
If you encounter any problems, please contact the manufacturer's warranty service
shop.

1. Preparing for sauna heater installation
Check the following before installing the sauna heater.
-The ratio of the heater's input (kW) and the sauna room's volume (m3). Volume recommendations are presented
in Tables 1 and 3 on page 5 and 6. The minimum and maximum volumes must not be exceeded.
-The height of the sauna room must be at least 1900 mm or 2100 mm depending on the heater power.
-Uninsulated and masonry stone walls extend the preheating time. Each square metre of plastered ceiling or wall
surface adds 1.2 m3to the sauna room's volume.
-Check page 6 and 7 Table 2 and 4 for a suitable fuse size (A) and the correct diameter of the power supply cable
(mm²) for the sauna heater in question.
-Conform to the specified safe clearance around the sauna heater.
-There should be enough room around the control panel for maintenance purposes. Also a doorway can be
considered as a maintenance area.
2. Installation
Follow the safety clearance specifications on pages 5 and 6 on tables 1 and 3 when installing the sauna heater.
The sauna heater is a floor-standing model. The base must be solid, because the sauna heater weighs
about 90 kg.
The sauna heater is levelled by the adjustable legs.
The sauna heater is fixed on the floor from its legs by the provided metal fasteners (2 pcs). This will keep the safety
clearances intact during use.
Walls or ceilings must not be clad with fibre-reinforced plaster board or other light-weight cladding, because they
may cause a fire hazard.
Installing the sensor near a supply air vent
The sauna room air should be exchanged six times in an
hour. The diameter of the supply air pipe should be
between 50 and 100 mm.
A circular air supply vent (360°) must be
installed at least 1000 mm away from the sensor.
An air supply vent with a flow-directing panel
(180°) must be installed at least 500 mm away from
the sensor. Air flow must be directed away from the
sensor.
3. Ceiling installation of the sensor
In ceiling installation, a 5-mm hole must be drilled to the
sensor case to allow any condensed water to drain.
Do not spray water directly towards the sensor or splash
water at it with a sauna scoop.
Installing the Extra NTC sensor
The additional OLET 31 sensor is connected to the Ext NTC connector on the RJ10 circuit board. For more details,
refer to the switch diagram. The additional sensor is installed on the sauna room wall no more than 500 mm from
the ceiling. Once the additional sensor has been connected to the circuit board, it is automatically activated. This
means that the temperature shown on the control panel is measured by the additional sensor.
The primary sensor installed above the sauna heater only has the limiter circuit that limits the maximum tempera-
ture to 110 °C. Even if the temperature is set to 110 °C on the control panel, the maximum temperature that can be
shown on the panel is approximately 90 °C, as the primary sensor above the heater limits the maximum tempera-
ture to 110 °C. Depending on individual preferences, the temperature of a sauna room is typically set between 70
and 80 °C.

The models of the control panels that can be used to control contactor cases WE 40. 31 (Trend) and 33 (Premium
Wifi).
Refer to the control panel operating manual for more specific instructions.
The contactor box is intended to be installed outside the sauna room. The cables must be installed using a fixed
installation. A connection box must be installed in the sauna room with a semi-fixed installation on the sauna
heater.
Failure to follow the minimum clearances in the installation instructions may cause a fire hazard.
Always check the sauna room before switching the sauna heater on.

3. This area should be avoided. Always use a silumin box.
In other areas, use a heat-resisting box (T 125 °C) and heat-resisting cables (T 170 °C). The
connection box must be clear of obstacles. When installing the connection box to zones 2 or 3,
refer to the instructions and regulations of the local energy supplier.
User and installation manual WE 40

10. Door switch
The door switch refers to the switch on the sauna door. This switch complies with regulations. Public and private saunas
must have a door switch, i.e. saunas where the heater can be switched on from outside the sauna, e.g. using an On/Off
button or a similar method.
If the door is opened before the heating sequence is started, (pre-set heating) automatic use (remote use) is disabled after
one minute. The door must be closed and the function restarted from the control panel.
If the door has been left open for more than five minutes while the heater is on, the heater is automatically turned off.
The heater can be turned on again from the control panel after the door is closed. The fault indicator light, if installed, will
start flashing. See installation instructions below.
Door switch instructions for installation and connection
The door switch is installed outside the sauna room on the upper edge of the door, at least 300 mm from the inner corner.
The switch part is installed on the door frame and the magnet is installed on the door. The distance between the switch and
the magnet is 18 mm.
When the door switch is installed on the top part of the door, TylöHelo recommends using the TylöHelo model with product
number 0043233, SSTL 8260371.
When the door switch is installed on the bottom part of the door, TylöHelo recommends using the TylöHelo model with
product number SP11000326, SSTL 8263280.
See the installation and user instructions supplied with the heater for instructions.
Figure 6. Installing the door switch
Table 5. Connecting the door switch to an RJ10 connector.
11. Remote controlling
The contactor case can be controlled remotely by a closing contact, which can also be pulse triggered for on-off,
wire the contacts to pins 3 and 4 of a RJ10 connector. The cable size is 24 AWG or 26 AWG. The maximum length
of the 24 AWG cable is 200 m, while the 26 AWG cable must be no longer than 130 m.
