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
page 3. 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
3
m to the sauna room's volume.
- Check page 5 on Table 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 3 on table. The sauna heater is levelled by
the adjustable legs
- There should be enough room around the sauna heater controls for maintenance purposes. Also a doorway can be considered as
a maintenance area.
- Only a single sauna heater is allowed per sauna room
Installation
Follow the safety clearance specifications on page 3 when installing the sauna heater. A thin panel is not a suitable mounting base;
the mounting base must be reinforced with timber behind the panel. The minimum clearances specified on page 3 must be followed
even if the sauna room wall materials are incombustible.
Walls or ceilings must not be clad with fibrereinforced plaster board or other light-weight cladding, because they may cause a fire
hazard.
See the control center installation and operation information, from the control center operation and Installation guide.
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.
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
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.
