2. 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 (m
in Table 5 on page 11. The minimum and maximum volumes must not be exceeded.
- The height of the sauna room must be at least 2100 mm or 2200 mm depending on the heater power. See Table 5 for the
correct minimum height for that heater.
- Uninsulated and masonry stone walls extend the preheating time. Each square metre of plastered ceiling or wall
3
surface adds 1.2 m to the sauna room's volume.
- Check page 10 Table 3 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.
guard rail is allowed around the heater.
- There should be enough room around the control panel for maintenance purposes. Also a doorway can be
considered as a maintenance area.

2.1. Installation

Follow the safety clearance specifications when installing the sauna heater.
The sauna heater is a floor-standing model. The base must be solid, because the sauna heater weighs
about 130 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
InInstalling 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.

2.2. 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.

2.3. 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 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.
