EN General safety instructions
1 General safety instructions
1.1 Mounting and electrical installation
The installation instructions are intended for qualified
personnel familiar with the laws and regulations appli-
cable to electrical installations at the installation site.
Observe the following general safety instructions
during mounting, configuration and commissioning
of the product.
Risk to life and limb and risk of fire
Risk to life and limb from electric shock or fire in the event of im-
proper or faulty electrical connection. This risk remains also after
completion of the installation work.
The electrical installation of the relay box and other electrical
systems or equipment with a fixed mains connection must only
be performed by a trained electrician from an authorized elec-
trical company.
The sauna system units must be completely disconnected from
the mains supply before commencing installation and repair
work.
Ensure compliance with the applicable standards and regula-
tions for electrical installation.
The housing cover must only be removed by a trained special-
ist.
Risk of injury and fire
If the integrated battery in the control panel is not replaced cor-
rectly, there is a risk of explosion which can lead to injury and fire.
The integrated battery may only be replaced by a qualified specialist.

EmoTec D/H USA - Installation and Operating Instructions EN-7
General safety instructions
Fire hazard from overheating
Insufficient ventilation can lead to device overheating and fire.
Do not install control panels, relay boxes and modules in en-
closed cabinets or wood paneling.
Observe the sauna heater manufacturer’s safety and installa-
tion instructions.
Observe the cabin manufacturer’s safety and installation in-
structions.
Touchable glass surfaces on the outside of the cabins must not
reach more than 76°C / 171°F. Otherwise provide proper pro-
tection.
Damage to the unit
Corrosive or heavy saline atmospheres damage the contacts in the
control panel, in the relay box and on the sensors.
The control panel, relay box and sensors should not be installed
in a corrosive or heavy saline atmosphere.
Damage due to incorrect mounting location
The control unit is not suitable for outdoor use.
The unit should be operated inside buildings only. It should not
be exposed to harmful environmental conditions. Harmful en-
vironmental conditions include, for example: humidity, mois-
ture, possible formation of condensation or weather that
promotes corrosion, as well as other weather conditions.
Similarly, excessive cold and extreme exposure to sunlight must
be prevented.
Protect the unit accordingly if there is an increased risk of me-
chanical damage.

EN-8 Installation and Operating Instructions - EmoTec D/H USA
EN General safety instructions
1.2 Operator instruction
The operator of the sauna cabin must be instructed in the general
safety instructions during commissioning. The operator must be
given a copy of the operating instructions.
The operator must make the end user aware of safety instructions
that are relevant to the end user.
The operator must be familiar with the settings for the heating
time and understand how it is controlled.
Fire hazard
Objects placed on the heater can ignite and cause fires.
Do not place objects on the heater.
Fill the rock store as directed.
Inspect the sauna cabin prior to each commissioning.
Risk to life and limb from electric shock and fire
A risk to life and limb from electric shock or fire arises in the event
of improper repair work. This risk remains also after work is com-
pleted.
The housing cover must only be removed by a trained special-
ist.
Repairs and installations must only be performed by a trained
specialist.
The sauna system units must be completely disconnected from
the mains supply before commencing any repair work.
Use only original spare parts from the manufacturer.
Health risks
Spending time in a sauna cabin can lead to serious health risks or
even death for persons with health impairments.
Persons with health impairments who spend time in a sauna
must consult a doctor before entering a sauna cabin.

EmoTec D/H USA - Installation and Operating Instructions EN-9
General safety instructions
Damage to health
Excessive time spent in a heated sauna cabin can lead to overheat-
ing of the body (hyperthermia), which may cause serious health
problems and even death. Hyperthermia occurs when the core
temperature of the body exceeds the norm by a few degrees.
Symptoms 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 fetus in
the case of pregnant women, inability to physically leave the room
and unconsciousness.
Alcohol, drugs, and medications increase the risk of hyperthermia.
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.
Floor heating in the sauna cabin results in additional warming
of the legs and can lead to health risks.
Equipment damage due to overuse
Excessive humidity in commercial sauna cabins can lead to prop-
erty damage.
If the sauna cabin is used commercially, the heating time must
be set so that it switches off automatically after a specific period
of time.
If the heating does not switch off automatically after a defined
heating period, cabin use must be supervised at all times.
Inspect the cabin before each use.

EN-10 Installation and Operating Instructions - EmoTec D/H USA
EN General safety instructions
Operation by children or persons with reduced mental
capacity
Children and persons with reduced mental capacity can put them-
selves at risk.
Children must be supervised to ensure they do not play with
the unit.
Children under 8 years of age should not operate the sauna
cabin.
The settings for the heating time must only be changed by chil-
dren under 8 years of age if they are supervised by an adult.
The sauna cabin must only be used by persons with reduced
mental capacity, or limited physical or sensory abilities under
supervision or if they have been previously instructed in its use
and understand the risks.
Children and persons who have not received proper instruction
must not clean or service the system.

2.5 Heating period limitation
The heating period for the sauna heater is limited to one hour.
2.6 Intended use
EmoTec D/H USA is designed to operate sauna heaters in sauna cabins. The
relay box and control panel are intended only for mounting on the wall.
EmoTec D/H USA is suitable for cabins used in private and commercial set-
tings.
The control unit is not suitable for outdoor use. It must be
operated only inside buildings and may not be exposed to
environmental conditions such as extreme humidity and
moisture or the possible formation of condensation or corro-
sive substances in the ambient air, as well as other weather
conditions. Similarly, excessive cold and extreme exposure to sunlight
must be prevented. Protect the unit accordingly if there is an increased risk
of mechanical damage.
The control unit is not suitable for installation at a height of over 2000 m
(6.562 ft).

3 Installation
3.1 Routing the lines
All lines should be routed before installing the control unit. The connec-
tions can be plugged in after installation, since the control unit’s front
panel can be removed.
NOTICE
Electronics malfunctions
Routing data and power supply lines together can lead to elec-
tronics malfunctions because, e.g., the sensor will not be detected.
Do not route sensor and sauna bus lines together with power
supply lines.
Route cable ducts separately.
Data lines must be routed and connected in such a way that they are not
openly accessible. They should be routed between the insulation and the
outer wall of the cabin. Cabin insulation must be installed in such a way
that the temperature in the area in which cables are routed
cannot exceed 65°C / 140°F.
If the data lines are installed outside on the wall, they must be protected by
a cable duct.

Connecting cables and fuses
When using 4 to 6-core cables, the type of AWG cable specified in the table
increases by one unit.
Example: AWG 12 > AWG 10.
* Only use copper lines (cable type 1) that are approved for temperatures
of min. 100 °C.
** Only use copper lines (cable type 2) that are approved for temperatures
of min. 180 °C.
*** The dimensions of cables and fuses may vary. Observe the information
