Electric Heater Insulation Resistance

When performing the final inspection of the electrical installations, a “leakage” may be detected when measuring the heater’s insulation resistance. The reason for this is that the insulating material of the heating elements has absorbed moisture from the air (storage, transport). After operating the heater for a few times, the moisture will be removed from the heating elements.

Do not connect the power feed for the heater through an RCD (residual current device)!

Installation of the Control Unit and Sensor
The control unit includes detailed instructions for fastening the unit on the wall. Install the sensor as shown in figure 5.

Resetting the Overheat Protector
See the instructions for use of the selected control unit model.

The reason for overheating must be resolved before resetting the overheat protector!

Sauna Room

See WARNINGS AND NOTES!
See TECHNICAL DATA!

Sauna room structure

• A. Insulation wool, thickness 50–100 mm. The sauna room must be insulated carefully so that the heater output can be kept moderately low.
• B. Moisture protection, e.g. aluminum paper. Place the glossy side of the paper towards the sauna. Tape the seams with aluminum tape.
• C. Vent gap of about 10 mm between the moisture protection and panel (recommendation).
• D. Low mass 12–16 mm thick panel board. Before starting the paneling, check the electric wiring and the reinforcements in the walls required by the heater and benches.
• E. Vent gap of about 3 mm between the wall and ceiling panel.
• F. The height of the sauna is usually 2100–2300 mm. The minimum height depends on the heater (>Technical data). The space between the upper bench and ceiling should not exceed 1200 mm.
• G. Use floor coverings made of ceramic materials and dark joint grouts. Particles disintegrating from the sauna stones and impurities in the sauna water may stain and/or damage sensitive floor coverings.

NOTE! Check from the fire authorities which parts of the firewall can be insulated.
Flues which are in use must not be insulated.
NOTE! Light protective covers which are installed directly to the wall or ceiling may be a fire risk.
NOTE! Make sure that the water dripping onto the sauna floor enters the floor drain.

Heater Output
When the walls and ceiling are covered with panels and insulation behind the panels is adequate, the heater output is defined according to the volume of the sauna. Non-insulated walls (brick, glass block, glass, concrete, tile, etc.) increase the need for heater output. Add 1,2 m³ to the volume of the sauna for each non-insulated wall square meter. For example, a 10 m³ sauna room with a glass door equals the output requirement of about a 12 m³ sauna room. If the sauna room has log walls, multiply the sauna’s volume by 1,5. Choose the correct heater output > Technical data

Blackening of the Sauna Walls
It is perfectly normal for the wooden surfaces of the sauna room to blacken in time.

The blackening may be accelerated by:

• sunlight
• heat from the heater
• protective agents on the walls (protective agents have a poor heat resistance level)
• fine particles disintegrating from the sauna stones which rise with the air flow.

Sauna room ventilation
The air in the sauna room should change six times per hour. Figure 11 illustrates different sauna room ventilation options.

Note! Do not place the supply air vent so that the air flow cools the temperature sensor

• A. Placement area for air supply vent (Ø 50 – 100 mm). If mechanical ventilation is used, air supply vent should be placed above the heater. If natural ventilation is used, air supply vent should be placed under or next to the heater. The diameter of the supply air pipe must be 50–100 mm.
• B. Exhaust air vent (Ø 100 – 200 mm). Place the exhaust air vent near the floor, as far away from the heater as possible. The diameter of the exhaust air pipe should be twice the diameter of the supply air pipe.
• C. Optional vent for drying (closed during heating and bathing). The sauna can also be dried by leaving the door open after bathing.
• D. If the exhaust air vent is in the washroom (Ø 100 – 200 mm), the gap underneath the sauna door must be at least 100 mm. Mechanical exhaust ventilation is mandatory.

Sauna Room Hygiene

• Bench towels should be used during bathing to prevent sweat from getting onto the benches.
• The benches, walls and floor of the sauna should be washed thoroughly at least every six months. Use a scrubbing brush and sauna detergent.
• Wipe dust and dirt from the heater with a damp cloth. Remove lime stains from the heater using a 10% citric acid solution and rinse.

OPERATING INSTRUCTIONS

See WARNINGS AND NOTES!
See TECHNICAL DATA!
See INSTALLATION IMAGES!

Placing of sauna stones
The placing of sauna stones has a major effect on the heater’s safety and steam-creation properties.

Important information about sauna stones:

• 60 kg is a suitable amount. The amount of stones varies, depending on the type of stone.
• Only stones with a diameter of 5–10 cm are allowed.
• The stone surface may be rounded. The use of stones with a cleavage surface is not allowed.
• Suitable stone materials are peridotite, olivine diabase and olivine.
• Ceramic ‘stones’ and soft soapstone are not allowed. They do not absorb enough heat as the heater is being used. Soft stones may crumble and block the air vents. This may break the heating elements and cause the product to behave unlike it was designed.
• Rinse any stone dust off the stones before placing them in the heater.

How placing the stones, observe the following:

• Installation Images: 8.
• Start with the biggest stones, placing them at the bottom and sides. This ensures sufficient air ventilation and forms a steady base for the stone space.
• Place the stones closely against the steel grid, and loosely at the top. Make sure the heating elements are not visible between the stones. A dense layer will prevent direct heat radiation from overheating materials around the heater. Pay particular attention to the corners where the heating elements are closest to the frame. Placing stones loosely in the middle will allow air to flow through the heater, heating the sauna and sauna stones well.
• Place stones one by one. Do not drop them in the stone space.
• Do not wedge stones tightly between the heating elements. Make sure that the heating elements retain their original position and shape despite the stones.
• Support the heating elements with stones so that they remain perpendicular to the heater.
• Do not place anything in heating element tunnel.
• Place the stones so that the weight of each stone rests on another stone, not on the heating elements.
• Do not pile a stack of stones on the heater. The stones may reach the level of the heater’s air ducts. An excessive amount of stones reduces ventilation and weakens the heater’s properties.
• Before using the heater for the first time, make sure that the stones cannot fall off.
• We recommended that you keep some extra stones in store to replace broken ones or to add any if the stone level becomes lower over time.

Piling of the Sauna Stones

Do not place any items or devices in the stone space or its vicinity that can change the amount or direction of air flowing through the heater.

If a heating element is not surrounded by stones, it can heat materials dangerously hot, even beyond the heater’s safety distances. Make sure that the heating elements are not visible beyond the stones. As the user, you are responsible for ensuring that the stone space is properly maintained throughout the heater’s life cycle.

Maintenance:
Due to large variation in temperature, the sauna stones disintegrate in use. Rearrange the stones at least once a year or even more often if the sauna is in frequent use. At the same time, remove any pieces of stones from the bottom of the heater and replace any disintegrated stones with new ones. By doing this, the heating capability of the heater stays optimal and the risk of overheating is avoided. Check occasionally whether the stone level has become lower. Make sure that the heating elements do not become visible over time. The stone level is likely to become lower in about two months after the stones have been placed.

Heating of the Sauna
When operating the heater for the first time, both the heater and the stones emit smell. To remove the smell, the sauna room needs to be efficiently ventilated. If the heater output is suitable for the sauna room, it will take about an hour for a properly insulated sauna to reach the required bathing temperature. The sauna stones normally reach the bathing temperature at the same time as the sauna room. A suitable temperature for the sauna room is about 65–80 °C.

Using the Heater
Before switching the heater on always check that no objects have been placed on top of the heater or inside the given safety distance.

Heaters are controlled using a separate control unit. See the instructions for use of the selected control unit model.

Throwing Water on Heated Stones
The air in the sauna room becomes dry when warmed up. Therefore, it is necessary to throw water on the heated stones to reach a suitable level of humidity in the sauna. The effect of heat and steam on people varies – by experimenting, you can find the levels of temperature and humidity that suit you best. Aim water only on the stones.

The maximum volume of the ladle is 0.2 liters. If an excessive amount of water is poured on the stones, only part of it will evaporate and the rest may splash as boiling hot water on the bathers. Never throw water on the stones when there are people near the heater, because hot steam may burn their skin.

Water quality requirements
The water to be thrown on the heated stones should meet the requirements of clean household water. Only special aromas designed for sauna water may be used. Follow the instructions given on the package.

Hardness: most important substances are magnesium (Mg) and lime, i.e. calcium (Ca)| Precipitates| Ca: <100 mg/
Chloride-containing water| Corrosion| Cl: <100 mg/l
Chlorinated water| Health risk| Forbidden to use
Seawater| Rapid corrosion| Forbidden to use
Arsenic and radon concentration| Health risk| Forbidden to use

Instructions for Bathing

See WARNINGS AND NOTES!

• Begin by washing yourself.
• Stay in the sauna for as long as you feel comfortable.
• Forget all your troubles and relax.
• According to established sauna conventions, you must not disturb other bathers by speaking in a loud voice.
• Do not force other bathers from the sauna by throwing excessive amounts of water on the stones.
• Cool your skin down as necessary. If you are in good health, you can have a swim if a swimming place or pool is available.
• Wash yourself after bathing.
• Rest for a while and let your pulse go back to normal. Have a drink of fresh water or a soft drink to bring your fluid balance back to normal

Troubleshooting
