THE BEST
SAUNA EXPERIENCE
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 spe-
cial feature of local historic smoke saunas is the lower tempe-
rature 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 in

3
which we analyzed 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 sanarium, 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 orbs 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!

These instructions for installation and use
are intended for the sauna owner or main-
tenance provider, as well as the electrician
responsible for installing the Saunum Air
heater with a sauna room indoor climate
device. After installing the heater with an
indoor climate device, the instructions
must be handed over to the owner or main-
tenance provider.
Before using the Saunum Air heater with
an indoor heat equalizer, read the instal-
lation and safety instructions.
The Saunum Air is intended for heating the
sauna room at 140–194 °F and for levelling
the sauna room climate during steaming.
Please note!The heat equalizing module
and the heater of the sauna must not be
operated in temperatures exceeding
194 °F!
Do not use the Saunum Air for
any other purposes!
To connect the Saunum Air to the
power network, a control device
for the control of electric heaters is
required. The control device must
correspond to the power of the
heater used according to Table 1
on page 8.
Saunum Air is intended for use with
Saunum AirIQ only. Use of any other control
type will void both warranty and UL listing.
NOTE: To ensure the longevity of the
device, make sure that the temperature
of the sauna room at the height of the
lower part of the device does not exceed
176 °F. If it is exceeded, the thermal
protection will be applied and the fan
will stop; the fan will start running again
if the temperature drops below the fuse
limit of application.
The manufacturer is not responsible for any
malfunction caused by an overrun of the
authorized operating temperature.

HEATING
THE SAUNA ROOM
Before using the Saunum Air for the rst
time, make sure that:
• the electrical connections meet the
requirements
• the supply voltage corresponds to
the nominal ratings allowed for the
Saunum Air
• the grounding (GND) is in working
order
• the attachments of the sauna cli-
mate device housing are in order
• the Saunum Air is properly attached
to the wall
• the over-current fuses are in working
order the fan rotor rotates smoothly
• there are no tools or materials left
after mounting the device in the
housing.
When switching the Saunum Air on, check:
• the direction of the air ow – the air
intake from the upper and the out-
put from the lower opening
• that there is no vibration or excessive
noise when the fan is running.
When the Saunum Air is switched on for
the rst time, the heating elements and the
stones will emit an odor. The sauna room
must be properly ventilated to remove the
anticipated initial smell.
Presuming proper insulation of the room
and that the power of the heater is suitable
for the sauna size, it takes 45–90 minutes to
reach the desired temperature.
The stones are usually heated to proper
temperature for water usage at the same
time as the sauna room. Turn the Saunum
Air fan on just before entering the sau-
na room; this will help prevent the sauna
bench from overheating and using exces-
sive energy.
Saunum’s recommended temperature
for sauna operation is 149°F to 176 °F.
USING THE SAUNA
CLIMATE DEVICE
Before switching the Saunum Air
on, always make sure that nothing
is above or near it.
The operating time of the sauna climate de-
vice model Sauna Air may be adjusted by a
separate control device.
• Do not connect the device directly to
the utilities and/or power!
• The Saunum Air must not be used if
the components of its housing have
been removed and/or the wiring dia-
gram has been changed.
• Children should not be allowed to
access or play with the Saunum Air.
DIRECTION FOR USE

11
• When switching the Saunum Air on
and o, refer to the instructions for
use of the control device you are
using.
After using the sauna, make sure
that all parts of the Saunum Air are
switched o (the heating and the
fan have stopped).
ADJUSTING
THE TEMPERATURE
It is recommended to keep the air
circulation fan of the Saunum Air
switched o during the heating of
the sauna room!
This will allow the sauna room to heat up
faster and the bench will not get too hot
during the warming process. To nd the
right setting, start testing at the lowest
temperature and lowest airow rate. If the
temperature becomes too high while in the
sauna room, reduce the maximum tempe-
rature in the sauna room or lower the fan
speed of the Saunum Air.
REGULATION OF THE
SAUNA
The amount of air circulation generated by
the device is regulated by the AirIQ touch
pad, which allows for control of air speeds
to your preferred comfort level. To regulate
the air temperature in the sauna room,
there is a steam air cooling damper on the
left side of the heater housing, lower than
the device stone area (see page 23). The
recommended setting is to keep the cooling
damper 1/3 open. To cool the steam, try to
open the damper little by little.
USE OF
HIMALAYAN SALT
The Saunum Air comes with Himalayan salt.
The use of salt orbs in the device is optional
and does not aect the main function of
the device if not elected.
To use the salt, they must be installed in
the sockets between the air outlet grille
and the fan. Make sure that the salt nested
correctly in each individual slot and do not
impede the fan rotation.
To install or remove the salt, remove the
air output grille (see page 27) and place
the salt in their sockets. After installing or
removing the salt, reposition the air output
grille. The Saunum Air may only be used
with the air output grille in place!
Do not use/start the device if the salt be-
come dislodged near the fan housing!
The use of third-party salt is not
covered by the device warranty.
DIRECTION FOR USE

LADLING WATER
ON THE HEATER
The air in the sauna becomes dry as it heats
up.Therefore, it is necessary to create steam
to achieve a suitable level of humidity. The
eects of heat and steam on people are dif-
ferent. When testing the dierent settings
of the Saunum Air, you will nd the most
suitable combination of temperature and
humidity. The eects of heat and s team on
people are dierent. When testing the dif-
ferent settings of the SAUNUM heat equa-
lizer, you will nd the most suitable combi-
nation of temperature and humidity.
The volume of the sauna ladle should
not exceed 6.4 uid oz. When throwing
water, the amount of water should not
exceed 6.4 uid oz, because by pouring
too much water on the stones at once,
some of it may be sprayed outwards in
splashes of boiling water.
Make sure that people are at a safe distance
from the heater when creating steam! Hot
steam and water splashes cause skin burns.
The water to be ladled or tossed lightly onto
the heater must meet the requirements
for clean domestic water. Only fragrances
specially designed for sauna may be used
in the water. Follow the instructions on the
package.
LOADING
THE STONES
Stacking stones has a great eect on the
operation of the heater.
Important to know:
• The diameter of the stones must be
2–4 in.
• Use Saunum stones.
•Do not use light, porous ceramic
“stones”, or soft tiles in the heater.
They do not store enough heat when
heated and can result in damage to
the heating elements.
• Wash any dust o the stones and
dry them before placing them in the
heater.
When using Saunum equipment,
we always recommend doing so
with high-quality polished sauna
stones!
When loading the stones, note the following:
•Do not allow the stones to fall into
the heater.
•Do not force the stones between the
heating elements.
• Do not allow the stones to rest on
the heating elements with their own
weight, but load the stones so that
they support each other.
• Do not stack the stones on the heater.
•Do not place objects in the vicinity of
the stone area or the fan of the sauna
climate device that may change the
amount or direction of the air ow-
ing through the Saunum Air.
DIRECTION FOR USE

WARNINGS
Staying in the sauna room for a long time
raises your body temperature, which may
be dangerous to your health!
• Do not touch the hot heater – the
stones and the outside of the heater
may burn you!
• Do not allow children, disabled or
sick people into the sauna room
without supervision!
• Consult a doctor about medical con-
cerns related to steam, heat, and/or
salt treatment!
• Make sure you are not allergic to salt
treatment. Saunum is not respon-
sible for potential side eects of salt
treatment in the sauna room!
• Consult a pediatrician or doctor
about use of the sauna by children!
• Be careful when moving in the sauna
and sauna room, as the bench and
the oor may be slippery!
• Do not go to the sauna under the in-
uence of alcohol, drugs, or narcotics!
• Do not sleep in the hot sauna room!
• Sea air and humid climates may
cause an oxide layer (rust) on the
metal surfaces of the heater!
•A guardrail or fence is required
around the heater to prevent burns
from accidental contact.
•Make sure you have proper ventila-
tion in the sauna room. Saunum is
not responsible for possible salt cor-
rosion of equipment and machinery.
•Do not hang towels and clothes to
dry in the sauna room – this may
cause a re hazard!
•Excessive moisture may damage the
electrical equipment!
• Clear obstructions closer than 20” in
front of the fan opening!
• Sauna users must not keep their feet
or other body parts closer than 20 in.
in front of the fan!
Please note. The electric heater requires
a control panel and stones.
Do not leave the fan of the heat
equalizing module running when
you are not in the sauna room –
this will cause an excessive energy
con-sumption, and the sauna
bench will become too hot!
WARNINGS

14
Contact a qualied sauna
service specialist to perform
maintenance. In the case of any
disturbances in the operation of
the Saunum Air, stop use of the
device immediately and have
the device inspected by a person
authorized by Saunum.
THE SAUNUM AIR IS NOT HEATING OR
BLOW AIR. ENSURE THE FOLLOWING:
• That the heater breakers and fuses
are in working order.
• That all wiring is properly connected.
• That the Saunum Air is switched on.
• The maximum temperature in the
sauna room is to your liking.
THE SAUNA ROOM HEATS UP TOO
SLOWLY. THE WATER LADLED OVER THE
STONES COOLS THEM DOWN QUICKLY.
• Make sure that the air circulation-
fan of the heat equalizing module
is switched o during sauna room
heating.
• Make sure that the breakers and
fuses of the Saunum Air are in
working order.
• Make sure that all heating ele-
ments have reached a hot tempe-
rature when the heat equalizing
module is in use.
• Increase the selected temperature
on the display panel.
• Make sure that the power output
(KW) of the heater is sucient.
• Check the stones. Stones that are
placed too tightly, falling down/
sinking closer over time, or the
wrong type of stone may inter-
fere with the air ow through the
heater and therefore reduce the
heating speed.
•Make sure that the ventilation of
the sauna room is correct.
THE SAUNA ROOM HEATS UP QUICKLY,
BUT THE TEMPERATURE OF THE STONES
IS INSUFFICIENT. THE WATER THROWN
ON THE STONES FLOWS DOWN.
• Make sure that the power output
(KW) of the heater is not too high.
If the power of the heater is suit-
able for the sauna room, it takes
45–90minutes to reach the desired
temperature in a properly insu-
lated sauna room.
• Make sure that the ventilation of
the sauna room is correct.
• Reduce the speed of the heat
equalizing module.
THE WALL COVERING OR OTHER
MATERIAL NEAR THE HEATER BECOMES
DIRTY QUICKLY.
•Observe the safety distance
requirements.
SOLVING PROBLEMS

15
• Make sure that no heating ele-
ments are visible between the
stones. If the heating elements are
visible, turn o the device, let the
stones cool, and lift them so that
the heating elements are comple-
tely covered.
Stones placed too sparsely may
cause the heating elements to
overheat and make the indoor
climate of the sauna room un-
comfortable and may cause a re
hazard!
THE WOODEN SURFACES OF THE SAUNA
ROOM BECOME DIRTY OVER TIME.
This process may be accelerated by:
• direct or indirect sunlight
• warmth produced by the heater
• wall protectors (protection equip-
ment has poor heat resistance)
• ne particles from the stones.
THE HEATER SMELLS.
• See section HEATING THE SAUNA
ROOM page 10.
• A hot heater may amplify odours
mixed with air, but this, however,
is not caused by the sauna nor the
heater. Causes include paint, glue,
oil, spices, etc.
THE SAUNUM AIR IS MAKING NOISE.
• There is always a certain noise
when the fan is running. If it is not
uniform and/or accompanied by a
metallic sound, the fan is likely to
need maintenance or repair. Check
that there are no foreign objects in
the fan air vents.
• Try switching the fan to a lower
speed.
• Loud sounds are likely to be caused
by stones cracking due to heat.
• Thermal expansion of the heater
parts may cause noise when the
heater warms up.
SOLVING PROBLEMS

16
• the prescribed occupational safety
and personal protective equipment
is used when performing the work;
•the connection cables are undam-
aged. In the event of damage to the
connection cables, have the cables
replaced by a qualied electrician
in accordance with the applicable
standards and requirements before
continuing maintenance and clean-
ing work.
The device housing can be cleaned with
a cloth dampened with water. Do not use
pressure washers, running water, chemical
cleaners, or solvents to clean the housing!
Use a 10% citric acid solution to remove
scale and rinse with water.
Excessive dirt can prevent the fanfrom
operating correctly, causing an increase in
noise when operating. Noise may also in-
crease due to damage/bending of the fan
blades. Make sure that there are no foreign
objects or salt in the working area of the fan
rotor.
The fan will naturally stay free of debris
with regular use. If cleaning is needed, we
recommend contacting a sauna airow
specialist.
CAUTION! Using compressed air to
clean the fan can permanently dam-
age the fan rotor! The fan bearings
are maintenance-free and must be
replaced if problems occur.
MAINTENANCE
Due to large temperature uctuations,
stones tend to break down. Stones must
be restacked at least once a year and even
more frequently when using the sauna of-
ten. When restacking the stones, remove
stone fragments from the bottom of the
heater and replace the broken stones with
new ones. By monitoring this, the heating
capacity of the heater remains optimal and
the risk of overheating is avoided.
If you use Himalayan salt with the Saunum
Air, it is recommended to inspect the salt
once a year and, if necessary, replace worn
and broken salt with new ones. Make sure
that there are no foreign objects in the fan
air vents of the heat equalizing module.
CAUTION! Before maintaining
and cleaning the Saunum Air, the
device power supply must be dis-
connected from the power and/or
utilities, and the moving parts of
the unit must completely stop.
Before servicing and cleaning the Saunum
Air, make sure that:
• the Saunum Air is disconnected from
the power and/or utilities (in addi-
tion to the device’s power switch,
also by means of over-current break-
ers or fuses);
• the device fan has stopped com-
pletely;
MAINTENANCE

17
It is recommended to check all electrical
connections of the Saunum Air at least
once a year. This can be done by a certied
electrician.
SAUNA ROOM
A prerequisite for the installation of the
Saunum Air is a properly prepared sauna
room. The thermal insulation of walls and
ceilings must be appropriate, otherwise it
will take too much time and energy to heat
the room. The power supply cables for the
heater and the fan must be indicated on
the electrical connection board accordance
with Table 1 (see pages 8–9).
SAUNA ROOM
VENTILATION
The air in the sauna room must be changed
at least six times an hour.
Air intake ventilation in a
sauna room is mandatory.
Install the air intake vent under or next to
the heat equalizing module. The air intake
pipe must have a diameter of 3–1/4”–4”.
Air output ventilation in the
sauna room is mandatory.
Install the air output vent near the oor, as
far as possible fron the Saunum Air. The di-
ameter of the air output pipe must be twice
the diameter of the intake pipe.

DIRECTION FOR USE
SIZING
YOUR SAUNA
The volume and structures of the sauna
af-fect the selection of heater power. The
pow-er requirement increases if there
are glass surfaces or other cold surfaces
such as tile, brick, concrete, or stone
walls in the sauna.
In case there are any glass, tile, brick,
concrete, or stone walls in the sauna
room (excluding sauna room
door), an additional volume of 3.9
cubic foot for each square foot of these
wall surfaces should be added to the
sauna room size calculation.
To calculate it yourself, multiply
the height by the width and the
length in feet to get the cubic volume of
your sauna room. Then calculate the
square footage sum of brick, tile,
glass, or concrete surfaces. Multiply
the sum of this square footage by 3.90
and add it to your rooms cubic volume.
As a result, you will have your sauna
room volume based on which you
can choose the suitable sauna heater
output. If the result falls between two
different output values, we
recommend choosing the larger heater.

BEFORE THE
INSTALLATION
The installation of the Saunum Air must
be performed by a qualied electrician.
The connection of the device must be per-
formed in a stable location with a cable that
meets the temperature conditions. Protec-
tive grounding (GND) must be connected
to the connection terminal of the device,
with the cross-sectional area of the cable
being at least 14 AWG, 90˚C/194˚F. The
device must be powered from the control
device’s supply circuit, which is protec-
ted by over-current breakers. The required
over-current breaker sizes and the connec-
tion cables dimensions are given in Table 1
(see pages 8–9).
All the certied sauna control devices with
the operating capacity corresponding to
the capacity of the Saunum Air model used
in accordance with Table 1 (see pages 8–9)
may be used to control the sauna climate
control device.
Before starting the installation work,
read the installation instructions and
observe the following:
• The power and type of the heater are
suitable for the given sauna room.
The recommended sauna room
volume is given in Table 1 (see pag-
es8–9).
• The supply voltage is suitable for the
Saunum Air.
• At the installation site of the sau-
na climate device, the minimum
safety distances given in Table 1 (see
pages8–9), measured from the heat-
er housing, are guaranteed.
• The dimensions of the device are
shown in Figures 1 and 2 (see pag-
es21, 22).
• It must also be ensured that the
upper edge of the air output of the
is lower than the lower edge of the
bench.
• There must be no obstructions in
front of the air output from the air
ow must be able to ow freely
across the sauna room.
• The device works most eciently
when its hot air intake cap is installed
against the ceiling of the sauna room
and the air is blown under the bench.
• Safety distances must be complied
with unconditionally, as failure to do
so may result in a re hazard. Only
