Damage to health Spending time in a sauna cabin can lead to serious health risks or
even death for persons with health impairments.
Excessive time spent in a heated sauna cabin can lead to overheat-
ing of the body (hyperthermia), which may cause serious health
problems or even death. Hyperthermia occurs when the core tem-
perature of the body exceeds the norm by a few degrees. Symp-
toms of hyperthermia include fever, dizziness, lethargy,
sleepiness, and fainting. Side effects of hyperthermia include per-
ception disorders, inability to recognize the need to leave the
room, inability to identify imminent danger, harm to the foetus in
the case of pregnant women, inability to physically leave the room
and unconsciousness.
Alcohol, drugs, and medications increase the risk of hyperthermia.
Persons with health impairments who spend time in a sauna
must consult a doctor before entering a sauna cabin.
Warn sauna users by affixing a warning plate. Read the chapter
entitled 4.10 Warning plate, EN-39.
Health risks Floor heating in the sauna cabin results in additional warming of
the legs and can lead to health risks.
Adding essences or other additives for humidification could result
in a health hazard.
Observe the following when using the sauna:
Do not exceed the maximum recommended time in the sauna.
Leave the sauna cabin if your body responds abnormally to the
heat or if you do not feel well.
Avoid alcohol, drugs, and medications when you are using the
sauna.
Operating the unit The sauna heater must not be operated by people who have not
received proper training. There is a high risk of injury if the device
for rotating the rock stores is operated by people who have not re-
ceived proper training.
Children must not play with the unit. Cleaning and maintenance
must not be performed by children.
The crank handle must be kept out of the reach of sauna users
and only brought to the device by trained personnel when the
rock stores are to be rotated.
The rock stores must be immersed to the lowest position on the
device to prevent them from rotating.
Children must be supervised to ensure they do not play with

Installation
This chapter describes how to install the sauna heater with the mechanical
device.
The cabin must be constructed based on the design of the Skiff. In particu-
lar, access must be provided for maintenance, cleaning and servicing.
Prior to installing the unit, air inlets and outlets must be installed in the
cabin. It may be necessary to mount additional fans in the inlets/outlets.
Inspection openings must be installed in the external housing to allow the
sauna heater to be maintained and, where applicable, repaired, depending
on the precise setup. The shape of the cover plate may vary.
Fitting a floor drain is also recommended to allow the water to drain during
maintenance.
3.1 Specifications for the cabin
The cabin must be planned and installed according to specifications before
the sauna heater is installed.
Ensure that the total heat output can accommodate the cabin volume.
The floor on which the sauna heater stands must be level. In general, it
should be noted that the sauna heater must not be set on a floor made of
highly flammable material (laminate, flooring made of plastic material,
etc.). Ceramic tiles are recommended as a flooring option.
The heater stands on a pedestal and is attached to achieve the required
height. The pedestal must also be constructed from suitable material.
Electrical lines
All electrical installations laid inside the cabin must be suitable for silicone
cables and a temperature of at least 170°C. All lines must be routed in such
a way that they are well-protected, e.g. in a cable duct.
If single-core lines are used as connecting cables, they must be protected
by a flexible metal hose that is connected to the protective conductor.
The minimum cross-section of the connecting cable and the suitable cabin
size in relation to the connecting cable in kW can be found here:
2.4 Technical data, EN-16.
