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

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

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.

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.

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.
