Theboilerpipescanbeconnectedtotheinstallationbymeansof22mmcompressionttings.Forconnecting
tothick-walledpipe(weldedortted),adaptersshouldbeused.
The boiler is NOT equipped with a built-in internal lter.
Advice: ATAG Heating Technology Ltd recommend the installation of an in-line lter installed into the
heating return as close to the boiler as possible. ATAG Heating Technology Ltd recommend the use
of the:
ATAG iGuard Magnatic Filter FC000100 (5 year warranty)
Additives in the installation water are only permitted in consultation with the country distributor. See
chapter 9.2 for detailed information.
9.2 Water quality
Fill the installation with mains cold water.
Inmostcases,aheatingsystemcanbelledwithwateraccordingtonationalstandardsforwaterand
treatment of this water is not necessary.
InordertoavoidproblemswiththeCH-installations,thequalityofthellingwaterhastomeetthe
specicationsmentionedintable9.2.a:
Ifthellingwaterdoesnotmeettherequiredspecications,youareadvisedtotreatthewatertosuchan
extentthatitdoesmeettherequiredspecications.
The warranty becomes invalid, if the installation is not being ushed and/or the quality of the lling
water does not meet the specications recommended by ATAG Heating Technology Ltd. Always
contact ATAG Heating Technology Ltd in advance, if things are not clear or you wish to discuss any
deviations. Without approval, the warranty becomes invalid.
Installation:
- Theuseofgroundwater,demi-wateranddistilledwaterisprohibited.(onthenextpageyouwillndan
explanationofthesedenitions)
- Ifthemainswaterqualitymeetsthespecicationsmentionedintable9.3.a,youcanstartushingthe
installation before installing the device.
- Whilstushing,corrosionproducts(magnetite),ttingproducts,cuttingoilandotherundesirableproducts
have to be removed.
- Anotherpossibilityistoremovethepollutionbyinstallingalter.Theltertypehastotthetypeand
grainsizeofthepollution.ATAGHeatingTechnologyLtdrecommendslterusage.
- In this case, the whole piping system should be taken into consideration.
- The CH-installation has to be properly vented before using the system. For that purpose, we refer to the
commissioning chapter.
- Ifaregularwatertopupisrequired(>5%onanannualbasis),thenthereisastructuralproblemand
an installer has to solve the problem. Regularly adding fresh water to the system also adds additional
calcium and oxygen implying that magnetite and calcium residues can continue. The result may be
blockages and/or leakages.
- Theuseofanti-freezeandotheradditivesrequiresperiodicalqualitychecksofthellingwaterin
accordance with the period laid down by the additives supplier.
- Chemical additions are to be avoided and should only be used after ATAG Heating Technology Ltd has
approved their corresponding use.
- Should you wish to achieve the required water quality by using chemical additives, then this is your own
responsibility. The warranty on the product delivered by ATAG Heating Technology Ltd expires, if the
waterqualitydoesnotmeetATAGHeatingTechnology'sspecicationsorthechemicaladditiveshavenot
been approved by ATAG Heating Technology Ltd.
- On installation and during additions or changes at a later stage, ATAG Heating Technology Ltd
recommends to keep a record of the type of water used, its quality at the time, and if applicable, which
additives and quantities were added.
