2. Important information for your safety
The Qube sauna heater has been produced in accordance with the
applicable safety rules and regulations. However, hazards may oc-
cur during use. Therefore adhere to the following safety information
andthespecicwarningnoticesintheindividualchapters.
2.1. Intended use
The Qube sauna heater is intended solely for heating sauna cab-
ins, in conjunction with a sauna control unit which does not include
a remote start function.
The Qube sauna heater can also be operated using a sauna control
unit with a remote start function, but only in conjunction with the
optionalcut-o󰀨rockerswitch.
The Qube sauna heater can also be used in public saunas, but only
inconjunctionwiththeoptionalcut-o󰀨rockerswitch.
Any use exceeding this scope is considered improper use. Improper
use can result in damage to the product, severe injuries or death.
2.2. Safety information for the installer
●Installing and connecting the sauna heater may only be performed
when the power supply is disconnected.
●Installationmayonlybeperformedbyaqualiedelectricianor
similarlyqualiedperson.
●A fully disconnecting all-pole isolating device compliant with
overvoltagecategoryIIImustbettedonsite.
●Always use silicone cables that are heat-resistant up to 150 °C
to connect the sauna heater.

Instructions for installation and use p. 6/24
●Only install one sauna heater in the cabin. The Qube 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
spruce,hemlock,pineorr,orfromlaminatedwoodenmateri-
als. If laminated wooden materials are used, make sure that the
adhesiveusedinthemdoesnotgiveo󰀨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e󰀨ectsonthehealthofthesaunausers.
●The height of the sauna cabin must be at least 2.0 m.
● Observethespecicationsonvolumesandonventilationofthe
sauna cabin in chapter 10. Technical data.
●When positioning the sauna heater, observe the minimum safety
distances (see chapter 4.2. Safety distances).
●Also comply with the regulations applicable at the installation
location.
●For your own safety, consult your supplier in the event of prob-
lemsthatarenotexplainedinsu󰀩cientdetailintheinstallation
instructions.

4. Installation and connection
Take the following points into account when positioning and connecting the
sauna heater:
Ifthereissu󰀩cientventilation,theQubesaunaheatercanalsobesitu-
atedinafree-standingposition.Inthiscase,tthetemperaturesensor
to the cabin roof above the centre of the heater.
●Theelectricalconnectionmayonlybeperformedbyaqualiedelectricianor
similarlyqualiedperson.
●A fully disconnecting all-pole isolating device compliant with overvoltage
categoryIIImustbettedonsite.
●The Qube sauna heater is a free-standing heater. It does not need to be at-
tachedtotheoororsaunawall.
●Donotplacethesaunaheateronaoormadefromaneasilyammable
materialsuchaswoodorplastic.Suitableooringincludesceramictiles,for
example.
●The 3-shell technology means that no additional protection against contact is
required because the surface temperatures of the heater are low.
4.1. Installation location and sensor position
Position the heater centrally in front of the air intake opening in the cabin wall.
ComplywiththesafetydistancestothecabinwallspeciedinFig. 1 and Fig. 2.
Install the temperature sensor with excess temperature cut-out to the cabin wall
above the centre of the sauna heater. Maintain a distance of 15 cm to the sauna
cabin roof.
WARNING!
Danger of electric shock
●The sauna heater may only be installed and connected when the
power supply is disconnected.

5. Commissioning
5.1. Filling the stone container
The amount of stones suited to your heater output can be found
in chapter 10. Technical data (see page 23).
1. Wash the stones thoroughly using water and a brush before use.
Do not use any cleaning additives.
2. Beforellingtheheaterwiththesaunastones,checkthemforforeignobjects
and remove any remaining packaging.
3. Place the stones in the stone container. Stack the sauna stones loosely so
thataircanowthroughthegaps.
4. Make sure that the sauna stones do not protrude beyond the edge of the
stone container.
WARNING!
Risk of re due to overheating
If the sauna heater is used without sauna stones, the cabin walls will
becomeextremelyhot.Thiscouldcauseres.
●NEVER operate the sauna heater without the sauna stones.
5.2. Heating for the rst time
CAUTION!
Formation of smoke and odours when heating up for the rst time
Materials used during the manufacturing process will be present on
the new heating elements. These evaporate when the sauna heater is
heatedupforthersttime.Thisproducessmokeandanunpleasant
odour. Breathing in the fumes or smoke can be harmful to your health.
Perform the following steps when operating the sauna heater for the rst
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
heatingforthersttime.

Instructions for use for the user p. 20/24
WARNING!
Risk of re
Combustible objects that are placed on the heater will ignite and cause
res.
●NEVER place combustible objects on the sauna heater.
●MakesurethatNOammableobjectshavebeenplacedonthe
heater before operating it.
6. Operation
6.1. Operating the sauna heater
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.
6.2. Infusion
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.
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.
1. Select the highest possible temperature on the sauna control unit.
2. Heat up the sauna heater for half an hour.
Do NOT remain in the sauna cabin during this period.
3. Allowthesaunacabintoventilatethoroughlyafterheatingforthersttime.
4. 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 immediately
and repeat the initial heating up process followed by ventilation.
