moisture content may also cause damage to the electrical equipment.
-Do not sleep in the sauna
• Hyperthermia occurs when the internal temperature of the body reaches a level several
degrees above
the normal body temperature of 98,6 ºF. The symptoms of hyperthermia include an increase in
the
internal temperature of the body, dizziness, lethargy, drowsiness, and fainting.
The effects of hyperthermia include:
A. Failure to perceive heat
B. Failure to recognize the need to exit the room
C. Unawareness of impending hazard
D. Fatal damage in pregnant women
E. Physical inability to exit the room
F. Unconsciousness
WARNING – the use of alcohol, drugs, or medication is capable of greatly increasing the risk of
fatal hyperthermia.
Use only clean tap water on the stones – do
not use pool or spa water or sea water with salt,
as chlorine gas can be produced and the heating elements can be
damaged!
• No such objects or devices should be placed

inside the heater rock space or near the heater
that could change the amount or direction of
the air flowing through the heater, thus causing
the resistance temperature to rise too high,
which may set the wall surfaces on fire!
Do not operate heater without stones or if the
stones have been piled incorrectly so that the
heating elements are visible. Wrong piling of stones
cause a fire hazard!
Attn! Do no insulate the space
between the heater and the wall.

PRIOR TO INSTALLATION
Before you begin installing the heater, pay attention to the following
points in the heater:
•Beware of the sharp edges of the stainless-steel mesh. Use a long-sleeved
shirt and protective gloves during the installation and once taking the heater
out of the cardboard box.
•Read through this installation manual and the separate control unit manual
before you begin the installation of the heater.
•ATTN! This manual must be left with owner, manager or operator of the
Sauna after it is tested/used by electrician.
•The heater volume should be suitable for the sauna room volume. (Page 13:
Model table) shows the recommended sizes for each heater power output.
•A precondition for the given values is that the sauna room is well insulated.
Walls and ceiling are covered with wood panel.
• Check that supply voltage and amperages are available for the heater in
the building and main power supply (Page 12: Supply wiring)
• The breakers and the connection cables conform with valid regulations
and their dimensions are in accordance with regulations
• The location is suitable for the heater (Page 12: Safety distances)
Attn! Do no insulate the space between the heater and the wall.

ELECTRICAL INSTALLATION (for certified electrician only)
Beware of the sharp edges of the stainless-steel mesh. Use a long-sleeved shirt
and protective gloves during the installation and once taking the heater out of
the cardboard box. The electric installation may only be administered by a
qualified electrician adhering to current regulations.
Installation of the heater
1. Choose the place for the heater according to the required safety distances. The installation must be
carried out in the place where the heater will be situated. The safety distances for Electric IKI 6 – 9
kW are measured from the heater's mesh frame outwards (Page 12: Safety distances). Negligence
to comply with the safety distances may cause fire hazard.
2. Remove the protective plastic cover from the heater.
3. See applicable wiring diagram for the right heater model to be installed (Page 11), ATTN! Heater
must be permanently installed by using seal tight conduit between the heater and the wall of the
sauna room (plugs are not allowed in the sauna room). All Wiring must be done by a licensed
electrician, who must follow wiring diagram provided and adhere to local regulations. Use proper
AWG rated wire size and use copper wire suitable for 194 °F (90 °C) within sauna walls. Make sure
that the connecting cable will not be exposed to thermal radiation or mechanical strain. If the
rubber cable running inside the wall of the sauna is above 1000 mm from the floor, it needs to
endure temperatures up to 170Celsius /338Fahrenheit. The use of PVC-insulated cable as a
connecting cable is prohibited due to thermal embrittlement. Use grounding terminals provided in
sauna heater and control unit to properly ground the equipment as per NEC and local regulations.
4. Remove the base plate from the underside of the heater by unscrewing the three screws
(Picture 1). Lead the five-pole electric cable to the connection strip inside the element box
according to the Wiring diagram (page 11).
5. Once the heater is fully connected to the house cabling, measure that all the heating elements
function properly. If problems occur, contact the manufacturer's technical support or retailer.
ATTN! When making the final inspection of the installations, a “leakage” might be detected when
measuring insulation resistance. The reason for this is that the insulating material of the heating
elements has absorbed moisture from the air/ transportation. After 2 -3 times moisture will
disappear.
6. Close the base plate (Picture 2).
7. Position the heater in the appropriate place. Check that the safety distances (Page 12)to
inflammable materials are adequate before piling the stones in.

8
Piling of the stones
Beware of the sharp edges of the stainless-steel mesh. Use a long-sleeved shirt
and protective gloves during the installation and once taking the heater out of the
cardboard box! Wash the stones before piling. Olivine, olivine-diabase, peridotite
or black volcanite stones are recommended stones, in sizes 2-4 inches (5-10 cm) in
diameter.
1. Detach the two stainless steel mesh frames from one another using the key (2,5mm hexagon
socket) (Picture 3 and Picture 4).
2. Check that the guide for the elements is in place at the top of the heater and keeps them upright. It
should position appx. 15cm (6 inches) from the top of the elements (Picture 5).
3. Pile stones to the lower part of the frame until the level reaches 10 cm from the middle part
(Picture 6).This helps install the upper part within the lower frame. Idea is to pile a dense layer of
stones against the stainless-steel mesh frame and rest of the stones loosely inside in the center
part of the heater. Do not drop or throw stones into the heater. The dense layer prevents the direct
heat radiation to the overheating possibly flammable materials around the heater. The loose piling
of stones in the center part lets the air flow through the heater, resulting in a faster heating of
sauna and stones. Assure that elements do not touch each other or the heater mesh frame. Make
sure that the stones support the elements to stay vertically straight.
4. Slide the top part of the mesh back to its position and attach that to the lower part of the
meshframe (Picture 7).
5. Pile stones to the fill the upper part. You may loosen the element guide to make the piling easier
for the time of piling. At that point make sure that the elements remain straight when piling the
stones. A bare heating element can endanger combustible materials even outside the safety
distances. Check that no heating elements can be seen behind the stones!
6. To complete the piling, reattach the guide properly and leave in place. The heating elements should
be carefully covered. Please make sure that elements make NO contact with each other or with the
heater frame (Picture 8).
7. Attach the mesh frames by adding the cap on top of the upper mesh by using the key to tighten the
screw (Picture 9).
8. Affix the heater to the wall using the screws (Picture 10). ATTN! Check that the heater stands
steady and is level before doing this.
9. Connect the “steamguide” to the upper part of the heater (Picture 11).
10. Install the heat/steam deflector directly on top of the heater. Tighten the plate to the ceiling by using
4 screws. That will prevent the ceiling from overheating above the heater (Picture 12.).
11. Please place the metal “CAUTION” sign on the interior wall of the sauna room directly above the
heater (Picture 13.) in a visible place (screws and nails included). Place the metal “WARNING” sign
outside, on the door of the sauna room (Picture 14.).
12. We recommend the use of safety railings around the heater. However, the stainless-steel mesh
frame does not over-heat the way ordinary steel-cased heaters do.
13. The surface of the stones can settle after the heater is in use. Frequently check that the heating
elements do not become exposed. If this should happen, add more stones. The disintegration of
the stones depends on the type of stones and the frequency of use. The condition of the stones
should be checked yearly, and broken stones must be replaced with new ones.

Operating the heater timer and temperature
•The heater is equipped with the thermostat to adjust the sauna
temperature and timer to control when the heating starts and and
stops. it is prohibited to bypass the the timer or the thermostat.
•To set the TEMPERATURE in the sauna higher you can turn the
thermostat knob clockwise (+) and to set the temperature lower turn
the knob counter-clockwise (-).
•To set the TIME To turn the sauna on immediately turn the timer
switch past the first market area 0-1hr. Then turn the dial back until
you hear “click” sound. Then you have the heater turned on to 1hr
operating zone and the heating elements start heating up. Heater
will be then in operation for maximum 1 hr.
•The heater has “8+1hr” timer. That means that you can set the
heater to begin heating after a delay of up to 8hrs. If you tun on the
heater to “1-9hr” zone the heating will start automatically after the
selected delay time has elapsed
High temperature control (reset button)
•The heater has a build-in high limit control, which automatically will turn off the heater if the
temperature rises too high in the sauna. That limit control might also turn off the heater in case the
sauna stones have for some reason moved and exposed the heating elements. The elements should
then be carefully covered with the stones.
•To restart the heater, turn the timer first down to zero and then push the reset button firmly. The
button is located at the bottom part of the heater. If the heater will not start operating or
continues to shut off, contact IKI LLC for further assistance.

15
Warning placards
•There are 2 placards included in the shipment. CAUTION label must be installed visibly directly
above the heater on the wall. WARNING placard has to be attached to the door of the sauna.
Instructions for use and maintenance
•Before bathing for the first time, heat up the heater once to burn off the protective oil solvents
from the heating elements. Be careful to ventilate the sauna during that and afterwards.
•Before switching the heater on always check that there is nothing flammable on top of the heater
or inside the given safety distance
•The heating time is about 60–75 minutes depending on the size of the room and its ventilation.
Recommended bathing temperature for IKI stone pillars is 131- 167F (55–75C). The temperature
should be set to the desired range from the temperature knob in the control unit.
•Pouring water on the heater increases temperature and humidity. You can control the heat and
humidity by pouring the water to different parts of the heater. You can adjust the feel of the heat
and steam from soft to sharp by throwing water either to the side of the heater or by pouring
water on top of the stones at different places.
•Check that the heating elements do not become exposed as the stones shift about due to heat
expansion. The stones settle normally in the first 10-20 times when heater is used.
•Check the condition of the stones at least once a year and replace if necessary. Rearrange the
stones as advised in paragraph (Page 8: Piling the stones) once a year or even more often if the
sauna is in frequent use. Replace any disintegrated stones with new ones. By doing this, the power
output of the heater stays good and the risk of overheating is avoided.
•Do not throw water to the heater when there are people nearby: the steam coming off the heater
is burning hot. This might burn their skin. Do not throw too much water on to the heater. Maximum
amount is 12 ounces (0,5l). It is important to throw water on the heated stones to have a good and
comfortable level of humidity in the sauna.
•The water to be thrown on the heated stones should meet the requirements of clean household
water (Page 13).
•After taking the (Löyly) in the sauna, cool your skin down as necessary and allow your heart rate to
settle back to normal. Have a drink of fresh water or mineral water to help stabilize your fluid
balance.

16
Troubleshooting
If the sauna room does not heat up, check that:
•The power is on and the circuit breakers are in working condition and are the correct size.
•The timer is set to the operating range.
•The temperature is set in a controller to a higher temperature than the temperature in the sauna
room.
•The fuses are intact.
•The temperature restrictor (overheat protector) has not gone off. If temperature restrictor has
gone off, the reason for this must be solved before using heater again.
•The stones are piled correctly, not too tightly packed.
•Check that all heating elements glow when the heater is on.
•Check that the heater output is sufficient (Page 13: Model table)
•Check that the sauna room ventilation has been arranged correctly.
If the sauna heats up but the stones not (= water goes through without generating steam)
• Turn the temperature lower from the controller
• Check that the heater output is not too high (Page 13: Model table)
• Check that the heater output is not too high (Page 13: Model table)
• Check that the sauna room ventilation has been arranged correctly
If the wood panel starts to darken around the heater
Check that the requirements for safety distances (Page 12) are fulfilled.
Too tightly piled stones and the settling of stones or wrong stone type can stop the smooth air flow through
the heater. This might cause the overheating of surrounding materials. Check also that heating elements
cannot be seen through the stones. If heating elements are visible, rearrange the stones immediately
without further using the heater.
Other problems
If the heater makes noise, this can be caused by stones breaking due to heat and the thermal expansion of
heater parts. This noise may be evident when the heater warms up.
