●If infrared heaters are connected, they must have a safety temperature limiter.
For suitable infrared heaters see 2.1. Intended use on page 5.
●If infrared plates are connected, the WC4-IRF-F foil sensors must be used
and activated (see 4.3. Installing the foil temperature sensor on page 14
and 5.3. Connecting the foil sensor (optional) on page 17). For suitable
infrared plates see 2.1. Intended use on page 5.
●Automatic heating time limit
The infrared controller shuts down automatically after the maximum heat-
ing period for safety reasons (see also 6.3. Operating time on page 21).
The EN 60335-2-53 species a maximum heating period limit of 6 hours
for private infrared cabins. For infrared cabins in hotels, apartment blocks
and similar locations, a maximum heating period limit of 12 hours is
permissible. Extending the heating period limit to 18 hours or 24 hours
is only permitted in public infrared cabins.
!
The Infrabox Basic infrared controller is suitable for use with intrinsically
safe infrared heaters and infrared plates. If no intrinsically safe products
are being used, a safety temperature limiter must be connected.

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 2of 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 2of 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 1of the foil temperature sensor directly between the in-
sulation and heating foil 4.
1. Secure the foil temperature sensor with the strain relief 2outside the foil
area.
2. Lay the 2-pin cable 3in 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).
