INSTRUCTIONS FOR USE

Steamer operation

The steamer boils water in a reservoir with a capacity of 6 litres. The steamer is switched on with the ON/OFF switch, and is equipped with a signal light that is lit when the steamer is on. Steam generation begins approximately ten minutes after the steamer is switched on. A full water reservoir will produce steam for approximately two hours.
A thermostat measuring the sauna room temperature is located in the steamer. If necessary, the thermostat switches the steamer off when the temperature in the sauna room exceeds of the adjusted value.

Figure 1. The Harvia Sauna Steamer

Use

The steamer is easy to use. When the water reservoir is filled with water, the steamer can be switched on using the ON/OFF switch.
The thermostat adjusting wheel in the bottom of the steamer is turned to maximum setting. See figure 1, section 2.3. Heating the sauna.

Filling the water reservoir, cold steamer
Remove the grille on top of the reservoir and fill the reservoir with clean household water. The minimum filling amount of the reservoir is approximately 2 litres and its maximum capacity is approx. 5.5 litres. (Figure 2.)

Filling the water reservoir, hot steamer
When the steamer is hot, filling or adding water should be avoided, because the hot steam and hot steamer may cause burns. If, however, you have to fill the water tank while it is hot, proceed as follows, exercising extreme caution:

1. Switch the steamer off.
2. Pour cold water carefully onto the grille of the water reservoir. The water runs into the reservoir cooling down the hot water inside.
3. Drain off the cool water from the reservoir into a can or bucket and pour it down the drain.
4. Fill the water reservoir as instructed in section.

Draining the water reservoir
In order to ensure faultless operation of the steamer, the water reservoir must always be emptied after use. This procedure removes impurities condensed in the reservoir as result of evaporation.
Because the water in the reservoir is very hot immediately after use, it should be drained only after the water has cooled for a few hours after switching the steamer off. (Figure 3.)
Please also see subsections 1, 2, and 3 of section 2.2.2.

Figure 3. Draining the water reservoir

Heating the sauna

There are four methods available for heating a sauna equipped with a steamer and heater to bathing temperature:

Normal sauna, no steamer
The sauna is heated to the desired temperature with the heater only (40 °C–100 °C). The normal bathing temperature is approximately 65 °C– 85 °C.

Sauna and steam
The sauna is heated with the heater to a high temperature, 65 °C–85 °C, in addition to which the steamer is switched on to humidify the sauna air. The steamer automatically adjusts the amount of humidity according to the temperature of the sauna.
Thermostat adjusting wheel at maximum setting.

Softsauna and steam
The sauna is heated with the heater to a low temperature, max. 65 °C, in addition to which the steamer is switched on at maximum power to humidify the air in the sauna.
Thermostat adjusting wheel at maximum setting.

Steambath
The sauna is heated with the steamer only.
Thermostat adjusting wheel at maximum setting.
Usually the sauna is ready for bathing approximately 0.5–1 hour after the heater and steamer have been switched on.
To start with, the steamer’s thermostat should be kept at maximum set.

The use of fragrances
Liquid fragrances and fragrance bags can be used in the steamer. Liquid fragrances are poured into the stone cups in the steamer. Fragrance bags are placed on top of the steam grating. See figure 1.
When using fragrances, mind the hot steam evaporating from the steamer as it may burn. Avoid adding of water and placing of fragrances to a hot steamer. The stone cups must be washed with running water as often as necessary.

Drying the sauna room

The sauna room must always be allowed to dry thoroughly after the steamer has been used. In order to speed up the drying process, the heater can be left on with the sauna ventilation also on to the maximum.
If the heater is used to help dry out the sauna room, remember to switch it off after the given period of time.

Cleaning the steamer

Impurities from water, e.g. lime, will accumulate on the walls of the steamer’s water reservoir. For decalcification we recommend decalcifying agents intended for household appliances, e.g. coffeemakers and water kettles. These agents are to be used as instructed by the manufacturer. The outside of the steamer can be cleaned with the damp cloth. When cleaning the outside, ensure that the steamer’s operating switch is OFF.

Troubleshooting

If the steamer does not work, check the following:

• Is the water level in the reservoir sufficient?(see section 2.2.)
• Has the overheat protector engaged? (reset button on bottom of steamer >Figure 3)
• Is the temperature in the sauna too high(over 65 °C)?
• Is the steamer thermostat set at maximum?

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.

THE SAUNA ROOM

Information on the sauna room is given in the heater’s installation instructions.

Sauna room ventilation

The instructions to be followed as regards ventilation of the sauna room are given in the heater’s installation instructions (see also section

INSTRUCTIONS FOR INSTALLATION

Prior to installation

Prior to installing the steamer, please study the instructions for installation carefully.
Note! The heater must be installed according to the heater’s installation instructions.
The following steamer safety factors must be considered when installing the steamer:

• How to fill the water reservoir
• Unobstructed and safe use of the drain valve
• The steamer must not be installed in a place that people pass when entering the sauna
• Safety distances for the heater and steamer (please see the heater’s installation instructions for safety distances for the heater)
• The heater thermostat sensor must not be within the scope of the steam coming from the steamer
• The steamer’s minimum distance from the heater is 50 mm

Installation

The steamer is installed on the sauna room wall close to the heater. (Figure 4.)
The steamer is mounted on the wall with screws (4 pcs). First, drive the upper screws into the wall following the measures given in figure 5a. The steamer can then be mounted onto the screws on the wall with the help of the “keyholes” in the steamers rear/upper part. Finally, the steamer’s lower part is fastened onto the wall with two screws (Figure 5b).

Figure 4. Placement of the steamer with various heater models.

Note! measure min. A in the heater’s installation instructions.

Figure 5. Mounting the steamer onto the wall.

Electrical connections

The steamer may only be connected to the electrical network by an authorized professional electrician, in accordance with current regulations. The steamer is connected semi-solidly to the junction box on the sauna wall. The connection cable must be of rubber cable type H07RN-F or its equivalent. The cross section of the cable from the steamer to the signal light (an accessory that gives a signal when there is not enough water) must be equivalent to the supply cable of the steamer.
NOTE! Due to potential thermal damage, the use of PVC-insulated wire as the connection cable of the steamer is forbidden. The junction box must be splash-proof, and its maximum height from the floor must not exceed 50 centimeters.
If the connection and installation cables are higher than 100 centimeters from the floor in the sauna or inside the sauna room walls, they must be able to endure a minimum temperature of 170 °C when loaded (for example, SSJ). Electrical equipment installed higher than 100 centimeters from the sauna floor must be approved for use in temperatures reaching 125 °C (marking T125).
Further instructions concerning exceptional installations can be obtained from local electrical authorities.

Installation of the operating switch
The operating switch, supplied with the heater (the ON/OFF switch) must be installed in a dry place outside the sauna room at the height of approximately 170 cm.

Steamer insulation resistance

When the final inspection of the electrical installations is performed, a “leakage” may be detected when the steamer’s insulation resistance is measured. The reason for this is that the insulating material of the heating elements has absorbed moisture from the air (during storage/transport). Moisture will disappear from the heating elements after the steamer has been heated a few times.
Do not connect the power supply to the steamer through the RCD (residual current device)!

Automatic filling

Connect the steamer to cold water mains using a flexible hose. Make sure that the connection has a shut-off valve. The sauna and/or washing facilities should have a floor drain in case of hose damage or leaks. Close the tank drainage valve and open the filling shut-off valve of the tank. Close the shut-off valve once you have ended bathing.

Always fill the water reservoir before use!

SPARE PARTS

We recommend to use only the manufacturer’s spare parts.
