UTION Corrosion of the system due to presence of glycol Uninhibited glycol will turn acidic under the influence of oxygen This process is accelerated by presence of copper and at higher temperatures The acidic uninhibited glycol attacks metal surfaces and forms galvanic corrosion cells that cause severe damage to the system It is therefore of extreme importance W that the water treatment is correctly executed by a qualified water specialist that a glycol with corrosion inhibitors is selected to counteract acids formed by the oxidation of glycols W that in case of an installation with a domestic hot water tank only the use of propylene glycol including necessary inhibitors classified as Category 3 according to EN1717 or equivalent based on the applicable legislations is allowed In other installations the use of ethylene glycol is permitted as well that no automotive glycol is used because their corrosion inhibitors have a limited lifetime and contain silicates which can foul or plug the system W that galvanized piping is not used in glycol systems since its presence may lead to the precipitation of certain components in the glycol s corrosion inhibitor that it has to be made sure the glycol is compatible with the used materials in the system CAUTION Units without backup heater kit installed are obligatory always to use glycol NOTICE Be aware of the hygroscopic property of glycol it absorbs
