VALLOX 132 E/VKLTHREE QUESTIONS ABOUT VENTILATIONSEASONAL CALENDARNOTE!For more detailed instructions,see page 8.1. THREE QUESTIONS ABOUT VENTILATION1.1. Why is air replaced in dwellings?Good ventilation promotes healthy living for both residents and the building. Air in a dwelling needs tobe replaced in order to remove not only humidity brought about by living but also impuritiesemanating from structures and human bodies. Impurities of indoor air include carbon dioxide,formaldehyde, radon and other gases as well as dust.Mechanical ventilation is needed in order to be able to adjust air circulation as needed bythe residents. In a tightly sealed house, air does not circulate sufficiently by natural means.Even in a poorly sealed house air is only replaced because of differences between indoorand outdoor air temperatures, or because of winds. This means that ventilation is dependenton weather conditions and cannot be regulated.It is especially important that humidity and carbon dioxide content of the indoor air stay ata healthy level. Recommended humidity content of good indoor air is approximately 45%.Humidity content is lower in winter and higher in summer and autumn. Dust mites thrive inindoor air if humidity exceeds 50%, and if humidity stays at over 60% for a long time inwinter, water will condense in the cold structures of the house and mould will start to form.The recommended maximum carbon dioxide content in good indoor air is circa 1,000 ppm.1.2. What are the characteristics of adequate ventilation?• Indoor air stays fresh in all the rooms of the dwelling, also in bedrooms during night.Without adequate ventilation carbon dioxide content tends to rise high especially in bedrooms.• The bathroom and the sauna get dry quickly.• During the heating season, the windows and other outer wall structures remain dry.• Humidity in indoor air is not condensed in the ventilation ducts.• Air is fresh in the toilet as well.1.3. How much air is replaced?For air to be clean to breathe, it has to be replaced with outdoor air every two hours. In a new anda renovated house, air circulation needs to be boosted during the first year in order to removeharmful gases and structural humidity. In buildings that are more than a year old and dry,ventilation can be regulated as needed. Ventilation is boosted during for instance a saunabath, clothes washing and cooking, and reduced during very cold periods or when thereis nobody at home.Autumn• Wash or change the coarse filter and cleanor change the fine filter if needed.• Check that the heat recovery cell is clean.• Check that the condensing water outlet isnot clogged.Spring• Wash or change the coarse filter and cleanor change the fine filter if needed.• Clean the fan blades and the post-heatingunit if needed.• Check that summer ventilation is inoperation.3VALLOX 132 E, order of duct outlets1.
