THE BEST SAUNA
EXPERIENCE TO HAVE!
I
am very glad that you have invested in the Saunum
device, and I believe that our innovative technology
will offer you a wonderful and extraordinary sauna
experience.
I have a degree in thermal engineering and come from the
Southern Estonia, where my love for saunas began.The special
feature of local historic smoke saunas is the lower tempera-
ture and higher humidity level than, for example, a classic
Finnish sauna. In ordinary saunas, the stone volume of the
sauna heater is generally small. Such an arrangement can
cause a sudden, burning hot steam and an extremely uneven
temperature, where your head and shoulder level is really hot,
but your feet are left cold. Such an experience can be quite
unpleasant and may cause headaches and lead to body stress.
However, in ancient smoke saunas and Native American sau-
nas, the stones were rst heated during the day.Then the heat
stored in the stones was used to cleanse the body and create a
truly enjoyable sauna experience.
Inspired by the experience of a smoke sauna, I wanted to
create an innovative solution that combines the best features
of an authentic sauna with modern technology; enabling a
pleasantly mild and relaxing sauna experience without pain-
fully scorching steam. For that, however, I had to solve the
problem of how to achieve an even temperature, at both the
head and foot levels. My development work was supported
by research done alongside Tallinn University of Technology,

3
in which we analysed the thermal stratication and air move-
ment in the sauna room. Saunum was born in cooperation
between scientic thinking and technological innovation.
Saunum’s unique patented mixing system of air layers cap-
tures the hot steam that rises under the ceiling of the sauna
room, mixes it with the cooler air from the surface of the oor,
and directs the milder steam back evenly. This makes for an
enjoyable, unaggressive heat. You can sit in the sauna for a
longer time, and enjoy a sweat and a deep cleanse without
feeling tired. The stone volume of our heaters is signicantly
larger than other sauna heaters, which is the reason for the
especially pleasant indoor climate with long and soft steam.
A moist steamy sauna, a therapeutic salt sauna, or a healthy
aroma sauna – all of these functions are available on Saunum’s
devices to create a truly relaxing sauna experience. When
using Himalayan salt balls in our device, salt ions that are
benecial to skin and respiratory tract evaporate and the
steam circulates these into the air. Adding a sauna aroma sys-
tem that blends steam and healthy aroma oil creates an even
more enjoyable sauna environment.
Saunum’s sauna devices are suitable for both adults and
children.
Have a pleasant sauna!

cian. The connection of the device must be
performed in a stable location with a cable
that meets the temperature conditions.
Protective earthing (PE) must be connected
to the connection terminal of the device.
The device must be powered from the con-
trol device’s supply circuit, which is pro-
tected by over-current fuses. The required
over-current fuses sizes and the connection
cables dimensions are given in Table 1 (see
pages 6–7).
All the certied sauna control devices with
the operating capacity corresponding to
the capacity of the Saunum Spa Session
model used in accordance with Table1 (see
pages 6–7) may be used to control the sau-
na climate control device.

ELECTRICAL CONNECTIONS
NB! Due to the potential danger of ther-
mal embrittlement, it is forbidden to use
a PVC-insulated cable as the connection
cable for the sauna climate device.
• The internal connections of the device
are made by means of terminals ac-
cording to Figure 2 (see page 17) and
Table 1 (see pages 6–7) in this manual.
• Protective earthing (PE) must be con-
nected to the connection terminal of
the device.
• The heater must be powered from
the 380 VAC (3-phase) 50/60 Hz sup-
ply circuit through a control device
protected by an over-current fuse of
the size shown in Table 1 (see pages
6–7).
• The power cable must enter the
housing of the sauna climate device
so that the water does not ow along
the cable into the electrical connec-
tion box of the housing of the sauna
climate device. The outer insula-
tionof the cable can only be peeled
o only from the part that is in the
device housing.
• If the connecting and installation
cables are located higher than
1000mm from the oor of the sau-
na room or inside the walls of the
sauna room, they must be able to
withstand a temperature at least
170 °C (e.g., SSJ). Electrical equip-
ment installed in the steam room
below 1000 mm must withstand a
temperature of at least 90 °C.
• The recommended cross-section
of the connection cable grooves is
given in Table 1 (see pages 6–7).
NB! The sauna climate device may only
be connected by a professional electri-
cian in accordance with the applicable
regulations!
ELECTRIC HEATER
INSULATION RESISTANCE
During the nal inspection of the electri-
cal installation, a leakage may be detected
when measuring the insulation resistance
of the sauna climate device, and which has
occurred due to the insulation material of
the heating elements absorbing moisture
from the air (storage, transport). After a few
uses of the sauna climate device, this mois-
ture will disappear.
NB! Do not connect the heater to the
mains via a residualcurrent device!
