Installation
Water and hydraulic system
Heating water quality
Fill the installation with
drinking water.
In most cases, a central heating
installationcanbelledwithwater
according to the nationally valid
regulations, whereby a treatment of the
water is not necessary.
To avoid problems, the quality of
thellingwatermustconformtothe
requirements in Table 1.
Ifthellingwatershouldnotconform
to these requirements, then it is
recommended to treat the water
correspondingly (see VDI2035).
Warranty claims become invalid if the
systemhasnotbeenushedduring
installation,orifthellingwater
quality does not conform to the ELCO
requirements (see Table 1).
If anything should not be clear, or
in case of deviations, always take
upcontactwithELCOrst.The
warranties lapse, if any changes are
made without an advance agreement/
release by ELCO.
Installation:
- The use of groundwater,
demineralized water and distilled
water, is not permitted (an
explanation of these terms can be
found on the next page).
- If the drinking water quality lies
within the limits of the values in
Table 1, then one can proceed
with the installation of the
systemandtheushingofthe
equipment.
- Residues of corrosion products
(magnetite), assembly materials,
cutting oil and other undesirable
products, must be removed during
theushingoperation.
- Another possibility for removing dirt
istheuseofalter.Theltertype
mustconformtothesystem-specic
requirements and the type of
contamination. ELCO recommends
theuseofalter.
In such a case, one should make
sure to take the entire piping
system into consideration.
- The central heating installation must
be de-aerated properly, before it is
taken into operation. Please review
the Chapter “Commissioning”
in this regard.
- If a regular topping up of water
is required (> 5% per year), then
there is a problem with the system
thatmustberectiedbyacertied
technician. Regular topping up
with fresh water and oxygen adds
lime to the system, which leads
to deposits.
- If an anti-frost agent or other
additives are used, then it must be
regularly checked to ensure that the
llingwaterqualityconformstothe
manufacturer requirements.
- Inhibitors may only be used after
consultation with ELCO.
- The use of such agents must be
protocolled.
Floor heating
Whenaoorheatingsystemis
connected that uses plastic pipes, it
must be ensured that it conforms to the
standard DIN 4726-4729. If the system
doesnotfullthestandard,thena
system separation must be foreseen.
If the regulations with regard to
plastic piping are not observed, then
warranty claims become null and
void (see the warranty conditions).
