System maintenance 77.2 Checking and correcting the water pressureYour heating system must contain sufficient water toensure the safe and correct function of your system.SYSTEM DAMAGEthrough frequent re-filling.CAUTION!The system may be damaged, dependingon water quality, by corrosion or scaling, ifyou frequently need to re-fill your systemwith make-up water.• Enquire from your local heatingcontractor whether you can use yourpublic water untreated or whether youneed to treat it before filling yoursystem.• Notify your local heating contractor ifyou need to regularly add make-upwater to your system.Fill make-up water into your system, if the systempressure is too low (see Chapter 3 "Using correct fill andmake-up water", page 7).7.2.1 When do you need to check the waterpressure in your heating system?– Recently filled in make-up water loses much of itsvolume in the first few days because it releasesgases. With new systems therefore check the waterpressure in your heating system initially on a dailybasis, and then after increasing intervals.USER NOTEAir pockets may form through the fill ormake-up water releasing gases.• Vent the system via the radiators and, ifrequired, replenish the system withmake-up water.– Check the water pressure monthly, if the heatingsystem still loses volume.We reserve the right to make any changes due to technical modifications.
