Instructions for installation and use | IKI electric heater with separate control unit Sivu 7Requirements for water qualityWater type Effect RecommendationHumus concentration Color, taste, precipitates <12 mg/lRautapitoinen vesi Color, smell, taste,precipitates<0,2 mg/lHardness: most important substancesare manganese (Mn) and lime, i.e.calsium (Ca)Precipitates Mn: <0,05 mg/lCa: <100 mg/lChlorinated water Risk to health ForbiddenSeawater Fast corrosion ForbiddenInstructions for use Before bathing for the first time, heat up the heater once to burn off the protective oil solvents. Becareful to air out the sauna room efficiently afterwards. The heating time is about 45–75 minutes depending on the size of the room and its ventilation.Recommended temperature for IKI stone pillars is 50–70 degrees. Pouring water on the heaterincreases temperature and humidity. You can control the heat and humidity by pouring the waterto different parts of the heater. The temperature should be set to the desired range from the temperature knob in the control unit. Check that the heating elements do not become exposed as the stones shift about due to heatexpansion. Check the condition of the stones once a year, and clean and replace as necessary. Do not throw water to the heater when there are people nearby: the steam coming off the heateris burning hot. Do not throw too much water on to the heater. Maximum amount is half a litre at atime.Trouble‐shootingIf the heater or sauna room does not heat up, check that: The power is on The timer is set to the operating range The temperature knob is set to a higher temperature than the temperature in the sauna room The fuses are intact The temperature restrictor (overheat protector) has not gone off. If temperature restrictor hasgone off, the reason for this must be solved before using heater again The stones are piled correctlyIf the wooden walls / parts take on a darker shade, check safety distances and piling of the stones does notleave resistor exposed or touching one another. If the resistors are visible they emit excessive heat.
