WARNINGS!
Do not smoke, use alcohol, or exercise in the sauna!
Do not exceed 30-minutes in the sauna at one time, as excessive exposure can
be harmful to health.The sauna should not be used as an endurance test!
Persons with poor health should consult their physicians before using the sauna!
Avoid re, do not place any combustible material over the sauna heater (towels,
bathing suits, wooden bucket or dipper)!
Use only clean water on the stones - do not use pool or spa water, as chlorine
gas can be produced and the heating elements can be damaged!
Keep away from the heater when it is hot. The stones and outer surface of the
heater may burn your skin.
Do not pour too much water on the stones.The evaporating water is boiling hot.
Do not let young, handicapped or ill people bathe in the saune on their own.
Consult your dodcutor about health-related limitations of bathing.
Parents should keep their children away from the hot heater.
Consult your child welfare clinic about taking little babies to the sauna.
- Age?
-Temperature of the sauna?
-Time spent in the warm sauna?
Be very careful when moving in the sauna, as the platform and oors may be
slippery.
Hyperthermia occurs when the internal temperature of the body reaches a
level several degrees above the normal body temperatures of 98.6°F (37°C).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) Fetal 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!

The stones disintegrate with use.
Therefore, they should be rearranged at
least once a year or even more often if the
sauna is in frequent use.At the same time,
any pieces of stone should be removed
from the bottom of the heater, and
disintegrated stones should be replaced
with new ones.
The guarantee does not cover any
faults caused by the use of stones not
recommended by the manufacturer.
Neither does the guarantee cover any
faults caused by disintegrated or too small
stones blocking the heater ventilation.
No such objects or devices should be
placed inside the heater stone space or
near the heater that could change the
amount or direction of the air owing
through the heater, thus causing the
resistance temperature to rise too high,
which may set the wall surfaces on re!
INSTRUCTIONS FOR USE
PILING OFTHE SAUNA STONES
The sauna stones for an electric heater
should be 2 - 4” in diameter. The heater
stones should be solid blocks of stone
specially intended for use in the heater.
Neither light, porous ceramic “stones” of
the same size nor soft potstones should
be used in the heater, because they may
cause the resistance temperature to rise
too high as a result of which the resistance
may be broken.
Stone dust should be washed off before
piling the stones. The stones should be
piled into the stone compartment over the
grating, between the heating elements
(resistances) so that the stones support
each other. The weight of the stones
should not lie on the heating elements.
The stones should not be piled too tightly,
so that air can ow through the heater.
See gure 1. The stones should be tted
loosely, and not wedged between the
heating elements, very small stones
should not be put into the heater at all.
The stones should completely cover the
heating elements. However, they should
not form a high pile on the elements.
Figure 1. Piling of the Sauna Stones

HEATING OFTHE SAUNA
Before switching the heater on always
check that there isn’t anything on top
of the heater or inside the given safety
distance. See item 1.6 “Warnings”.
When the heater is switched on for the
rst time, both the heater and the stones
emit smell.To remove the smell, the sauna
room needs to be efciently ventilated.
The purpose of the heater is to raise the
temperature of the sauna room and the
sauna stones to the required bathing
temperature. If the heater output is
suitable for the sauna room, it will take
about an hour for a properly insulated
sauna to reach that temperature. See item
2. “Sauna Room Construction - General
Information”. A suitable temperature for
the sauna room is about 149 - 176°F (65
- 80°C).
The sauna stones normally reach the
required bathing temperature at the
same time as the sauna room. If the
heater capacity is too big, the air in the
sauna will heat very quickly, whereas the
temperature of the stones may remain
insufcient; consequently, the water
thrown on the stones will run through.
On the other hand, if the heater capacity
is too low for the sauna room, the room
will heat slowly and, by throwing water
on the stones, and bather may try to raise
the temperature of the sauna. However,
the water will only cool down the stones
quickly, and after a while the sauna will
not be warm enough and the heater will
not be able to provide enough heat.
In order to make bathing enjoyable,
the heater capacity should be carefully
chosen to suit the size of the sauna room.
CONTROL UNIT OF HEATER
The ClubHeat / KG model heaters require
a separate control unit to operate the
heater.The control unit should be located
outside the sauna room in a dry place,
at a height of approximately 5’. The
temperature sensor, by means of which
the set temperature is maintained in the
sauna room, should be connected to the
control unit. The temperature sensor and
overheating limiter are located in the
sensor box installed above the heater.
The sensor box should be installed
in accordance with the installation
instructions of the control unit model in
question.
The ClubHeat / KG model heaters are
controlled with the HeatPad control unit.

THROWING WATER ON HEATED
STONES
The air in the sauna room becomes
dry when warmed up. Therefore, it is
necessary to pour water on the heated
stones to reach a suitable level of humidity
in the sauna.
The humidity of the air in the sauna room
is controlled by the amount of water
poured on the stones. A correct level of
humidity makes the bather’s skin sweat
and makes breathing easy. By throwing
water on the stones with a small ladle,
the bather should feel the effect of air
humidity on his skin. Both too high a
temperature and air humidity will give an
unpleasant feeling.
Staying in the hot sauna for long periods
of time makes the body temperature rise,
which may be dangerous.
The maximum volume of the ladle is 7
ounces. The amount of water poured on
the stones at a time should not exceed 7
ounces, because if an excessive amount
of water is poured on the stones, only
part of it will evaporate and the rest
may splash as boiling hot water on the
bathers.
Never pour water on the stones when
there are people near the heater, because
hot steam may burn their skin.
SAUNA WATER
The water to be poured on the heated
stones should meet the requirements
of clean household water. the factors
essentially affecting the quality of water
include the following:
• Humuos content (color, taste,
precipitates); recommended content
less than 12 mg/l.
• Iron content (color, smell, taste,
precipitates); recommended content
less than 0.2 mg/l.
• Hardness - the most important
substances are manganese (Mn) and
calcium (Ca);
• Recommended content of manganese
0.05 mg/l, calcium less than 100 mg/l.
Calcareous water leaves a white, sticky
layer on the stones and metal surfaces
of the heater. Calcication of the stones
deteriorates the heating properties.
Ferrous water leaves a rusty layer on the
surface of the heater and elements, and
causes corrosion.
The use of humous, chlorinated water
and seawater is forbidden.
Only special aromas designed for
sauna water may be used. Follow the
instructions given on the package.
TEMPERATURE AND HUMIDITY
OFTHE SAUNA ROOM
Both thermometers and hygrometers
suitable for use in a sauna are available.
As the effect of steam on people varies, it
is impossible to give an exact, universally
applicable bathing temperature or
percentage of moisture.The bather’s own
comfort is the best guide.
The sauna room should be equipped
with proper ventilation to guarantee
that the air is rich in oxygen and easy to
breathe.
Bathing in a sauna is considered a
refreshing experience and good for the
health. Bathing cleans and warms your
body, relaxes the muscles, soothes and
alleviates oppression. As a quiet place, the
sauna offers the opportunity to meditate.

AFTER INSTALLATION
TESTING OF SAUNA HEATER
1. After sauna heater has been properly
wired, according to appropriate wiring
diagram and local codes, turn sauna
breaker on in the main breaker panel.
(Note! Electrician must label “Sauna”
breaker.)
2. Turn thermostatic (heat) control to
on position (this is located either on
your heater or on your remote wall
control. If you have a wall control, the
indicator light will come on to show
that the sauna is heating). Set timer to
10- to 15-minutes.
3. Within 5-minutes, you should be able
to feel heat from heater elements
when holding hand over heater.
4. If the sauna does not heater, refer to
troubleshooting information.
5. It is normal for smoke to appear
during the rst heating, as protective
element coating needs to burn off.
Turn sauna on for 1-hour before using
for rst time, to eliminate smoke.

TROUBLESHOOTING
A. If the sauna heater does not operate
after initial installation and wiring:
1. Check circuit breaker in contactor to be
sure that it has not been shorted out.
2. Make sure that the current from the
control unit to the heater has been
switched on.
3. Check that the desired temperature
programmed in the control panel is
higher than the temperature of the
sauna.
B. If the sauna has been in operation, but
the heater ceases to operate:
1. Check breaker to make sure it is on.
2. Check that there is no time left in the
control panel.
3. Check overheat limiter reset button in
heater (reset is under the heater) to
see if it has been released.
4. Call your electrician or service person
for further help.)
NOTE! A GROUND FAULT INTERRUPTER
(GFI) should not be installed in, and does
not belong in a sauna. If used, the breaker
will trip, and damage could result.
C. If the sauna heater operates, but the
sauna room does not come up to
sauna temperature 160 - 185°F (70 -
85°C)
1. You must allow at least 30-minutes for
sauna heat-up time.
2. Is sauna thermometer located 6” from
ceiling, and is it above or close to
sauna heater? (This is proper location
for sauna temperature reading.)
Thermometer readings vary with room
heights and location. Eg. 180°F (82°C)
above sauna heater = 165°F (74°C) on
opposite wall = 140°F (60°C) on upper
bench = 120°F (49°C) on lower bench =
100°F (38°C) at oor level.
3. Check for proper wire size, amp
size, and proper wiring (according
to diagrams and information) also
necessary copper wiring.
4. Check the placement of stones to
make sure they are loosely spaced
around elements, to ensure good air
ow. Stones packed too tightly will
restrict air ow and reduce heating
capacity.
5. Check for heat loss (around or under
door, around ceiling light or fan - we
do not recommend ceiling light and a
fan does not belong in the sauna.
6. Is the room properly insulated?
7. Is the ceiling higher than 7’?
8. After checking all above, remove rocks
and check the heating elements for
holes or burned areas. (Only if heater
has been in use for some time.)
CAUTION! ELECTRICIAN OR
SERVICE PERSON!
1. BEFORE SERVICING HEATER,
CONTROL, OR CONTRACTOR, TURN
POWER OFF AT BREAKER!
2. Open junction box to make sure wires
are tightly secured with no loose
connections. Heater wire and all
connecting wires should be copper.
3. Check for burned spots or short in
wiring of timer or thermostat.
Sauna Heater’s warranty on parts is
void if installer/electrician fails to follow
necessary wiring information provided or
fails to follow code for proper wire size,
amperage, etc.
OVERHEATING LIMITER
Each heater is equipped with an
overheating limiter which is a safety
device. If an abnormal heating condition
should occur, the heater will automatically
shut off, and it will not come on again until
it cools.
To reset the overheating limiter, locate the
reset button (bottom front on wall models,
behind junction box at back bottom of
oor-mounted heaters) and push upward
until contactor kicks in. If the reset button
continues to trip, contact a qualied
service person. Be sure that a GFI has not
been installed.

MAINTENANCE INSTRUCTIONS
1. Use only clean water on sauna stones.
Do not use spa or pool water as it will
destroy your heater.
2. Clean water should always be used
in sauna buckets and water should
be dumped out after every use. Scour
buckets and dippers occasionally
when lm collects from usage. Use
plastic bucket liner in bucket to prevent
water leakage.
3. Scrub benches with a soft brush, using
soap and water or a mild disinfectant,
when needed - about once a week in
commercial saunas, or depending
upon sauna usage. For sanitation,
each bather should sit or lie on a towel
(this will prolong bench life).
4. Remove possible removable ooring
and wash waterproof oor with
disinfectant (e.g. Pine-Sol) about once
a week or as often as needed. Hose off
removable ooring to clean.
5. To maintain beautiful appearance of
sauna heater, remove water stains by
wiping with a damp cloth occasionally.
6. Our heaters require no special
maintenance when properly installed
by a qualied electrical contractor.
After 1 - 2 years of usage, the rocks
may need replacing if they have
crumbled or powdered (depending
upon sauna usage).
7. We strongly recommend a oor
that can be easily cleaned (concrete,
ceramic tile, or a poured type of
ooring). When this is provided, the
sauna can be easily cleaned and kept
in a sanitary condition with little effort.
A carpet is NOT recommended for a
sauna! A carpet becomes a perfect
breeding ground for bacteria in the
moist conditions of a sauna; and a
carpet promotes the spread of foot
diseases such as athlete’s foot.
8. In new construction, a oor drain
should also be provided, especially
in commercial saunas for sanitary
cleaning and maintenance. Seal wood
around glass in door - inside and
outside - withThompson’s Water Seal
to prevent warpage.
9. When sauna wood becomes stained
from perspiration, the wood may be
lightly sanded with ne sandpaper
to restore beautiful appearance. We
do not recommend stains or sealers
as toxic vapors may appear when
heated.
10. The sauna room will heat faster if the
higher vent is kept in a closed position
when heating. The lower vent may
always be kept in an open position.
11. Required warning signs should be
posted according to the instructions.
