   The main switch is marked with a 0 – 1 sticker.

5. 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 6, section 2.7 Preparing for sauna heater installation).

6. Information for users
   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)

7. 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.
   • For additional information about enjoying a sauna bath, please visit our website at: www.Sauna360.com

Heating the sauna

• Before turning the sauna heater on, make sure the sauna room is suitable for taking a sauna bath. When heated for the first time, the sauna heater may emit some odour. If you detect any odour while the sauna heater warms up, disconnect the sauna heater briefly, and air the room. Then turn the sauna heater back on.
• You should turn the sauna heater on 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.
• If you encounter any problems, please contact the manufacturer’s warranty service shop.
• Pleasant, smooth sauna bath temperature is about 70 °C.
• Do not put any objects on the sauna heater. Do not dry clothes on the sauna heater or anywhere in its vicinity.

Recommended sauna room ventilation

1. Sauna room
2. Washroom
3. Electric sauna heater
4. Exhaust valve
5. Exhaust flue or channel
6. Door to the sauna room

A ventilation valve can be installed here to be kept closed while the sauna is heated and during bathing.
Inlet vent can be positioned in the A zone. Make sure the incoming fresh air will not interfere with (i.e. cool down) the sauna heater’s thermostat near the ceiling.
The B zone serves as the incoming air zone, if the sauna room isn’t fitted with forced ventilation. In this case, the exhaust valve is installed min 1m higher than the inlet valve.
DO NOT ISTALL INLET VALVE WITHIN ZONE C, IF THE SAUNA HEATER’S CONTROL THERMOSTAT IS LOCATED IN THE SAME ZONE.
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.

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 500mm 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 temperature 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 temperature to 110°C. Depending on individual preferences, the temperature of a sauna room is typically set between 70 and 80°C.

Sauna heater stones
Quality stones meet the following requirements:

• Sauna stones should withstand heat and heat variation caused by vaporisation of the water thrown on the stones.
• Stones should be rinsed before use in order to avoid odour and dust.
• Sauna stones should have an uneven surface to supply a larger surface for the water to evaporate from.
• Sauna stones should be large enough, to allow good ventilation between the stones. This extends the useful life of the heating elements. It is recommended to use Vulkanite stones in the size of 10cm 15cm. E.g. Helo product 0043022
• Sauna stones should be piled sparsely in order to enhance ventilation between the stones. Do not bend the heating elements together or against the frame.
• Rearrange the stones regularly (at least once a year) and replace small and broken stones with new, larger stones.
• Empty the stone compartment regularly, at least once a year in private use, remove small and broken stones and replace them with new ones.
• In commercial use this operation must be performed at least every second month.
• Stones are piled so that they cover the heating elements. Do not, however, pile a large heap of stones on the heating elements. For a sufficient amount of stones refer to Table 1 on page 6. Any small stones in the package of stones must not be piled on the sauna heater.
• The warranty does not cover defects resulting from poor ventilation caused by small and tightly packed stones.
• Structural clay tiles are not allowed. They may cause damage to the sauna heater that will not be covered by the warranty.
• Do not use soapstone as sauna rocks. Any damages resulting from this will not be covered by the stove warranty.
• Do not use lava stone as sauna rocks. Any damages resulting from this will not be covered by the stove warranty.
• DO NOT USE THE HEATER WITHOUT STONES.

If the sauna heater will not heat up
If the sauna heater will not heat up, please check that:

• the power is on;
• the main fuses of the sauna heater are intact;
• is there any error messages on the control panel. In case of an error message on the control panel, please refer to the control panel instructions.
• THE PERSON INSTALLING THE SAUNA HEATER SHOULD LEAVE THESE INSTRUCTIONS AT THE PREMISES FOR THE FUTURE USER.

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 Table 1 on page 6. The minimum and maximum volumes must not be exceeded.
• The sauna room height must be a min. of 1900 mm.
• Uninsulated and masonry stone walls extend the preheating time. Each square metre of plastered ceiling or wall surface adds 1.2 m3 to the sauna room’s volume.
• Check page 10 Table 2 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. Please refer to page 6.
• There should be enough room around the control panel for maintenance purposes. Also a doorway can be considered as a maintenance area.

Installation

• Follow the safety clearance specifications on page 6 and 7 when installing the sauna heater.
• The sauna heater is a floor-standing model. The base must be solid, because the sauna heater weighs about 120 kg with stones.
• 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 clear-ances intact during use.
• Mounting of the sauna heater to the wall or the sauna benches available as an accessory (metal fastenings. S-ZH 58, 0043272).
• Walls or ceilings must not be clad with fibre-reinforced plaster board or other light-weight cladding, because they may cause a fire hazard.
• Only a single sauna heater is allowed per sauna room.

• Lift the support bar’s locking plate up from its normal position.
• Lift off the support bars.
• Pile stones up to the Helo marker.
• Reinstall the support bars.
• Install the support bars as above in the reversed order.
• Pile the stones so that they cover the heating elements.
• For specific instructions refer to section 2.5 Sauna heater stones.
• Figure 3 Preparing for piling the stones

Installing the support for heating elements

• Note that heating element support should always be used in order to prevent the heating elements from being bent into each other or out sideways.

Installation of the heating element support:

• Pile in stones up to halfway of the provided space. Position the support so that the heating elements stay between the openings.
• Tilt the support and press the pivots at each end of the support to the grooves in the inside of the heater’s vertical beams, one end at a time. The support for heating elements should stay levelled.
• Push the pivots at one end of the support to the grooves in the vertical beams.
• Press the pivots at the other end of the support to the grooves in the heater’s vertical beams.
• Subsequently, pile in stones up to the upper edge so that they cover the heating elements.
•  Figure 4 Installing the support for heating elements

Connection of the sauna heater to the mains

• The sauna heater must be connected to the mains by a qualified electrician and in compliance with current regulations. The sauna heater is connected with a semi-permanent connection. Use H07RN-F (60245 IEC 66) cables or a corresponding type. Other output cables (signal lamp, electric heating toggle) must also adhere to these recommendations. Do not use PVC insulated cable as a connection  cable for the sauna heater.
• A multipolar (e.g. 7-pole) cable is allowed, if the voltage is the same. In the absence of a separate control current fuse, the diameter of all cables must be the same, i.e. in accordance with the front fuse.
• The connecting box on the sauna wall should be located within the minimum safety clearance specified for the sauna heater. The maximum height for the connection box is 500 mm from the floor.
• Location the connection box See page 11.

• NOTE : Controlling the lights in the sauna with the circuit board is only possible with resistive loads (incandescent light bulbs). The circuit board relay cannot withstand capacitive loads (switched-mode power supply units). If the lighting fixtures in the sauna have transformers, for example LED or halogen lamps, the stove circuit board’s relay control must be fitted with a separate relay or contactor for  controlling the lights.
• Sauna heater insulation resistance:
• The sauna heater heating elements may absorb moisture from air, e.g. during storage. This may cause leakage currents. The moisture will be gone after a few heating sessions. Do not connect the heater power supply through a ground fault interrupter.
• However, adhere to the effective electrical safety regulation when installing the sauna heater.

Electric heating toggle

• Electric heating toggle applies to homes with an electric heating system.
• Sauna heater has connections (marked N-55) for controlling the electric heating toggle. Connectors N-55 and the heating elements are simultaneously live (230V). The sauna heater thermostat also controls the heating toggle. In other words, home heating turns on once the sauna thermostat cuts power off the sauna heater.

Locating the connecting box for the connection cable in the sauna room

A = Specified minimum safety clearance

1. Recommended location for the connecting box
2. alumni box recommended in this area.
3. This area should be avoided. Always use alumni 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.

Remote controlling

• The Heater can be remotely controlled by connecting a closed contactor, which can be pulse triggered, to connectors 3 and 4 of a RJ10 circuit board. The recommended cable size is AWG 24 or 26. The maximum length of an AWG 24 cable is 200 m when using a Pure controller. The maximum length of an AWG 26 cable is 130 m when using a Pure controller.
• Note! The sauna standard requires a door switch if the sauna heater is controlled from outside the sauna. An indicator light can be connected to the remote button terminal, it will be lit up when the remote command is activated. The indicator light shows an error by blinking rapidly, this error is caused by keeping the sauna door open for more than 5 minutes, the sauna heater will be shut down automatically. The remotely operated sauna heater stays on as long as the setting in the control panel (in private us max 6h). The sauna heater can be shut off at any time by the remote-control device.

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.
• The control panel automatically registers when the door switch is connected to the heater’s OLEA 99 circuit board. When us-ing the sauna for the first time after the installation, close the door to the sauna room and turn on electricity using the heat-er’s main switch.
• 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, Sauna360 recommends using the Sauna360 model with prod-uct number 0043233, SSTL 8260371.
• When the door switch is installed on the bottom part of the door, Sauna360 recommends using the Sauna360 model with product number SP11000326, SSTL 8263280.
