4. Installation
4.1. Installing the power supply unit
ATTENTION!
Damage to the unit
●Install the power supply unit in a dry place. Maintain a maximum ambient
temperature of 40 °C and a maximum humidity of 95%.
●A free circulation of air must be ensured to cool the power supply unit.
The power supply unit must not be covered by any objects or materials.
The power supply unit is installed on the cabin roof (Fig. 1), on the cabin wall or
in another suitable location in accordance with the ambient conditions. The power
is supplied with a mains connection cable and safety plug.
1. Screw the Infrabox power supply unit housing to the cabin ceiling or the cabin
wall with the four wooden screws provided (16 mm long).
Fig. 1 Installing the power supply unit
Installation instructions, only for experts p. 12/32
4.2. Installing the control unit
The control unit 2 of the infrared controller is installed on the outside wall
of the cabin with a maximum clearance of 10 metres from the power supply
unit 1 (see Fig. 2). For the installation, a standard jigsaw is required to cut out
the recess for the control unit. The operating unit can be installed both inside
and outside the cabin.
* For installation inside a sauna cabin, maintain a distance of at least 30 cm to
the ceiling. (see Fig. 2 Control panel position on page 12).
ATTENTION!
Damage to the unit
●The control unit 2 of the infrared controller is splashproof
(protection class IP X4).
●Work on the control panel may only be carried out using a standard screw-
driver. Using a cordless screwdriver may irreparably damage the housing.

If the foil temperature sensor is not tted directly on the infrared plate,
it will produce incorrect measured values. Install the foil temperature
sensor directly on the foil.
The foil temperature sensor is only required for infrared plate heating sys-
tems. Observe the details of the plate heating system manufacturer here.
4.3. Installing the foil temperature sensor
The foil temperature sensor is installed directly on the infrared heating plate and
xed with a cable strain relief (see Fig. 5: Installing the foil temperature sensor
on page 14).
Install the sensor head 1 of the foil temperature sensor directly between the in-
sulation and heating foil 4.
1. Secure the foil temperature sensor with the strain relief 2 outside the foil
area.
2. Lay the 2-pin cable 3 in the cabin wall and secure with cable ties.
3. A foil temperature sensor must be activated to use it (6.4. Foil sensor on
page 22).
