Commissioning

Filling the stone container

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. The stone basket 1 can be mounted at two different heights.
2. Position 2: fewer stones, shorter heating time, energy saving
3. Position 3 (set at factory): more stones, larger amount of water for pouring possible, creating more steam, longer heating times

The amount of stones suited to your heater can be found in chapter Technical data (see page 27).

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 and also between the heating rods. Stack the sauna stones loosely so that air can flow through the gaps.
4. Do NOT allow the heating rods to make contact with one another.
5. Make sure that the sauna stones do not protrude beyond the edge of the stone container

Heating for the first time

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.

NOTE!
Overheat protector of the device can go off also at temperatures below -5˚C / 23˚F (storage, transport, environment). Before installation take the device to the warm environment. The overheat protector can be reset when the temperature of the device is approx 18˚C / 64˚F. The overheat protector must be reset before using the device.

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. Heating the heating rods for the first time

2. Select the highest possible temperature on the sauna control unit.

3. Heat up the sauna heater for half an hour.
   Do NOT remain in the sauna cabin during this period.

4. Heating the evaporator for the first time

5. Select a low temperature and high humidity on the sauna control unit.

6. Heat up the evaporator with half the amount of water (see Filling the evaporator on page 20) Do NOT remain in the sauna cabin during this period.

7. Switch off the sauna control unit after approx. 15 minutes.

8. Allow the evaporator to cool (for approx. half an hour).

9. Empty the water tank (see Filling the evaporator on page 20)

10. Repeat step 2.b.

11. Allow the sauna cabin to ventilate thoroughly after heating for the first time.

12. If no smoke or odours form the next time the sauna heater is heated, you can start to use the sauna.
    If smoke or odours form again, leave the sauna cabin immediately, and repeat the initial heating process, followed by ventilation.

Operation

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.

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 only sauna control units without a remote start function are permitted for use with the Home combi sauna heater

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. 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.

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.

Only settings on the lower left side of the characteristic curve are possible; e.g.: at 60%, a temperature of 50 °C cannot be exceeded

The evaporator tank must be filled manually. If the water in the evaporator tank 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”.

Damage to the evaporator
Sea water, hard water, chlorinated water, herbs, essences or fragrances can damage the sauna heater.

• Only fill the evaporator tank with tap water.
• 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 7.5 on page 25 on page).

Filling the evaporator

Risk of scalding
If you pour water into the hot evaporator tank, hot steam is created.

• NEVER pour water into the hot evaporator tank.
• Check and fill the evaporator tank each time before starting combi mode.
• If the overheating protection has switched off evaporator heating, or if your sauna control unit reports a lack of water, allow the evaporator to cool down BEFORE you pour water into the evaporator tank.

Risk of scalding
If the evaporator tank is too full, boiling water will spray out of the evaporator tank.

• Fill the evaporator tank with 5 litres of water

1. Use a funnel 1 or remove the soapstone 2.
2. Only fill the evaporator tank with fresh tap water. You will need about 5 litres of water for this. This amount of water allows the evaporator to be operated for approximately 1 hour.
3. Remove the funnel 1 or put the soapstone back in

Using fragrances

If you wish, you can put liquid fragrances or dried herbs on the soapstone.

Observe the following points:

• Do not put fragrances directly into the evaporator tank.
• Carefully fill the trough in the soapstone, but only half full, so that the fragrances do not drip through the holes in the evaporator tank.
• Follow the manufacturer’s instructions on the packaging of the herbs and fragrances.
• Regularly clean the soapstone under running water.

Maintenance

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 have the fault corrected (see section 9. Problem-solving by the installer on page 26).
Heat the sauna heater for approximately 15 minutes every 5 to 6 weeks. This prevents moisture from building up on the heating rods during extendedperiods of non-use.

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.

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

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

Check the sauna stones at regular intervals and replace the stones at least once a year.

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.

Cleaning the evaporator tank
Drain and clean the evaporator tank after each use. Perform the following steps:

1. Wait until the water in the evaporator has cooled.

2. Place a receptacle (at least 5 litres) under the ball valve at the bottom of the evaporator.

3. Open the ball valve to the left until the remaining water flows out.

4. When the evaporator tank is empty, close the ball valve.

5. Remove the soapstone.

6. Clean the evaporator tank with a household brush with plastic bristles.
   Take care not to damage the tank sensor leads. Rinse with water.

7. Put the soapstone back in.

Descaling the evaporator tank

Descale the evaporator tank as required. To do this, use a descaling agent for household appliances. Observe the specifications and safety information provided by the manufacturer.

1. Remove the soapstone.
2. Empty the evaporator tank.
3. Prepare the descaling solution according to the manufacturer’s instructions.
4. Fill the evaporator with the descaling solution up to the top of the limescale.
5. Let the descaling solution take effect according to the manufacturer’s in-structions.
6. Place a receptacle under the ball valve at the bottom of the evaporator and drain the evaporator tank.
7. Rinse the evaporator tank twice with cold tap water.

Disposal

• Please dispose of packaging materials in accordance with the ap-plicable disposal regulations.
• Used units contain reusable materials as well as hazardous sub-stances. Therefore, do not dispose of your used unit 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 dur-ing long periods of non-use. This is a physical process and not a manufacturing fault. Under certain circumstances, the 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 procedure takes approximately 10 minutes. The safety function of the FI circuit breaker must subsequently be reactivated.
• If the problem persists, consult your supplier.

Resetting the overheat cut-out of the evaporator

• A temperature switch is responsible detecting any lack of water. If a certain water level in the evaporator tank is not complied with (approx. 1 l), this tem-perature switch switches off the heating element.
• At the same time, the feed-back to the WM control unit falls to 0 V – the control unit displays the message “LOW WATER”.
• In case the evaporator still overheats, there is a temperature cut-out as protec-tion. This cut-out must be reset manually. To do this, press the contact in the left side wall 1.
