We recommend cleaning the precipitator and emptying the ash bins before an emission measurement is made. Use adhesive to affix the seals, for example. Explanation of pictograms Only blow out the components with your mouth. Switch the boiler on/off with the mains switch. www.eta.co.at... - Page 5 No water or moisture in this area. No leaks in the components, for example, screw connection or maintenance cover. Technical illustrations The technical illustrations show the cleaning and maintenance of the EEP 333-500 precipitator; these steps are also valid for the EEP 250 precipitator.
