Commissioning

5.1. Filling the stone container
WARNING!
Risk of fire due to overheating
If the sauna heater is used without sauna stones, the cabin walls will
become extremely hot. This could cause fires.

• NEVER operate the sauna heater without the sauna stones.

The amount of stones suited to your heater can be found in chapter 11. Technical data (see page 26).

1. Wash the stones thoroughly using water and a brush before use. Do not use any cleaning additives.
2. Before filling 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 flow through the gaps.
4. Make sure that the sauna stones do not protrude beyond the edge of the stone container.

5.2. Heating for the first time
CAUTION!
Formation of smoke and odours when heating up for the first 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 first 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 first 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 first time.

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 first 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.

Operation

WARNING!
Risk of fire
Combustible objects that are placed on the heater will ignite and cause fires.

• NEVER place combustible objects on the sauna heater.
• Make sure that NO flammable objects have been placed on the heater before operating it.

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. Please note that the Concept R mini sauna heater is only suitable for use with sauna control units that have a remote start function.
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.

Maintenance

7.1. Extended periods of non-use
Moisture can accumulate in the heating rods in humid ambient conditions or during long periods of non-use. This is a physical process and not a manufacturing fault. Accumulation of moisture in the heating rods can lead to the FI circuit breaker being triggered. In this case, contact an electrician to correct the fault (see chapter 9. Problem-solving by the installer).
Heat the sauna heater for approximately 15 minutes every 5 to 6 weeks. This prevents moisture from building up on the heating rods during extended periods of non-use.
7.2. Cleaning the sauna heater
Make sure that the ventilation openings are free of lint and dust. This prevents the air circulation in the sauna heater from being restricted and prevents the device from overheating.
7.3. Changing the sauna stones
Sauna stones are subject to stress by the water poured on them, and by large fluctuations in temperature which occur during use. The sauna stones can become weak and brittle. Check the sauna stones at regular intervals and replace the stones at least once a year.

WARNING!
Risk of fire due to overheating
If the sauna heater is used without sauna stones, the cabin walls will become extremely hot. This could cause fires.

• NEVER operate the sauna heater without the sauna stones.

1. Remove the old sauna stones.
2. Clear the stone container of limescale deposits, dust and other contamination.
3. Wash the stones thoroughly using water and a brush before use. Do not use any cleaning additives.
4. Before filling the heater with the sauna stones, check them for foreign objects and remove any remaining packaging.
5. Place the stones in the stone container. Stack the sauna stones loosely so that air can flow through the gaps.
6. Make sure that the sauna stones do not protrude beyond the edge of the stone container.

Disposal

• Please dispose of packaging materials in accordance with the applicable disposal regulations.
• Used appliances contain reusable materials as well as hazardous substances. Therefore, do not dispose of your used appliance with household waste, but rather do so in accordance with the locally applicable regulations.

Problem-solving by the installer

Baking out of the heating rods
Moisture can accumulate in the heating rods in humid ambient conditions or during long periods of non-use. This is a physical process and not a manufacturing fault. Under certain circumstances, accumulation of moisture in the heating rods can lead to the FI circuit breaker being triggered. In this case, it is necessary to bake out the sauna heater under the supervision of an electrician. To do this, the protective function of the FI circuit breaker must be switched off. The baking out  rocedure takes approximately 10 minutes. The safety function of the FI circuit breaker must subsequently be reactivated. If the problem persists, consult your supplier.
