2. Important information for your safety
The Concept R combi sauna heater has been produced in accord-
ance with the applicable safety rules and regulations. However,
hazards may occur during use. Therefore adhere to the following
chapters.
2.1. Intended use
The Concept R combi is a sauna heater with integrated evaporator.
The Concept R combi is intended solely for heating sauna cabins
and for increasing the humidity within the sauna cabin. The Concept
R combi may only be used in conjunction with a sauna control unit
without a remote start function.
The Concept R combi sauna heater can also be used with a sauna
control unit with a remote start function, but only in conjunction with
the optional safety shutdown feature (CP-R-SWL).
The Concept R combi sauna heater can also be used in public
saunas, but only in conjunction with the optional safety shutdown
feature (CP-R-SWL).
Any use exceeding this scope is considered improper use. Improper
use can result in damage to the product, severe injuries or death.
Instructions for installation and use p. 6/26
2.2. Safety information for the installer

when the power supply is disconnected.
A fully disconnecting all-pole isolating device compliant with
Always use silicone cables that are heat-resistant up to 150 °C
to connect the sauna heater.
Only install one sauna heater in the cabin. The Concept R combi
sauna heater must not be used together with other sauna heaters
in a sauna cabin.
The roof and walls of the sauna cabin must be manufactured
from low-resin, untreated or thermally treated wood, e.g. Nordic
-
als. If laminated wooden materials are used, make sure that the
adhesive used in them does not give off formaldehyde. If other
materials than wood are used in the sauna cabin, these materi-
als must be heat-resistant and corrosion-resistant and must not
cause any negative effects on the health of the sauna users.
The height of the sauna cabin must be at least 2.0 m.

CAUTION!
Materials used during the manufacturing process will be present on the
new heating elements. These evaporate when the sauna heater is heat-
Breathing in the fumes or smoke can be harmful to your health.
Perform the following steps when
time and if the heating elements for the sauna heater have been replaced.
This prevents damage to health due to the fumes and smoke produced when
1.
a. Select the highest possible temperature on the sauna control unit.
b. Heat up the sauna heater for half an hour.
Do NOT remain in the sauna cabin during this period.
2.
a. Select a low temperature and high humidity on the sauna control unit.
b. Heat up the evaporator with half the amount of water (see page 20)
Do NOT remain in the sauna cabin during this period.
c. Switch off the sauna control unit after approx. 15 minutes.
d. Allow the evaporator to cool (for approx. half an hour).
e. Empty the water tank (see Filling the evaporator on page 20)
f. Repeat step 2.b.
g. Allow the sauna cabin to ventilate thoroughly after heating for
h. If no smoke or odours form the next time the sauna heater is heated,
you can start to use the sauna.
If smoke or odour is produced again, leave the sauna cabin immedi-
ately and repeat the initial heating up process followed by ventilation.
Instructions for use for the user p. 18/26
A sauna control unit is used to operate the sauna heater. For information on how
to operate the sauna control unit, read the operating instructions for the device
used. Please note that only sauna control units without a remote start function
are permitted for use with the Concept R combi sauna heater.
6. Operation
WARNING!
Combustible objects that are placed on the heater will ignite and cause
NEVER place combustible objects on the sauna heater.
heater before operating it.
6.1. Finnish sauna mode
In Finnish sauna mode, only the heating system operates. Dry heat is produced.
The temperature in the cabin is high (80 to 100 °C). The maximum humidity level
of 10% is low. The temperature in the sauna cabin is regulated by your sauna
control unit.
At the end of the sauna session, you can pour an infusion of water over the
stones. Pour water over the stones using a sauna ladle. The water evaporates
and the humidity in the sauna cabin increases.
With the optional safety shutdown feature (CP-R-SWL), the Concept
R combi sauna heater is also suitable for sauna control units WITH
a remote start function.
EN
Instructions for use for the user p. 19/26
When pouring water over the stones, observe the following points:
Only use tap water. Sea water, hard water and chlorinated water can damage
the sauna heater.
Only use fragrances and essential oils that are suitable for use in saunas. Follow
the manufacturer’s instructions on the packaging of the scented substance.
Do not pour the water onto the stones too quickly. Only this way will all the
water evaporate completely.
6.2. Combi mode
Both the heating system and evaporator operate in combi mode. The temperature
in the sauna cabin is lower than in Finnish sauna mode (approx. 40 to 65 °C),
with the relative humidity being considerably higher at 35% to approximately
70%. The maximum permissible relative humidity decreases with increasing
temperature. The temperature and the humidity in the sauna cabin are controlled
by your sauna control unit.
has been used up, an overheating protection function automatically turns off the
heating of the evaporator. The lack of water is reported to the sauna control unit
and displayed there, e.g. by an audible warning tone and the message “FILL”.
ATTENTION!
Damage to the evaporator
Sea water, hard water, chlorinated water, herbs, essences or fragrances can
damage the sauna heater.
Do not put herbs, essences or fragrances directly into the evaporator tank,
and only into the ceramic bowl over the evaporator.
Descale the evaporator regularly (see 7.6. on page 24).
Instructions for use for the user p. 20/26
CAUTION!
Risk of scalding
If you pour water into the hot evaporator tank, hot steam is created.
NEVER pour water into the hot evaporator tank.
mode.
If the overheating protection has switched off evaporator heating, or
if your sauna control unit reports a lack of water, allow the evapora-
tor to cool down BEFORE you pour water into the evaporator tank.
Filling the evaporator
CAUTION!
Risk of scalding
If the evaporator tank is too full, boiling water will spray out of the evap-
orator tank.
1. Remove the ceramic bowl 1 and
the steam funnel 2.
2. Place a receptacle (at least 5 litres)
under the ball valve at the bottom
of the evaporator.
3. Turn the ball valve to the left until

close the ball valve.
5. Fill the evaporator tank 3 with fresh tap

water up to the maximum mark. You will need about 5 litres of water for
this. This amount of water allows the evaporator to be operated for ap-
proximately 1 hour.
6. Replace the ceramic bowl 1 and the steam funnel 2.
