2.4.5 Heating and sanitary side connection
● Create a heating system according to the
safety requirements of EN 12828.
● With a sanitary connection you must comply
with
–EN 1717 – Protection against pollution of
potable water installations and general
requirements of devices to prevent pollu-
tion by backflow
–EN 806 – Specifications for installations
inside buildings conveying water for human
consumption
– and, in addition, the country-specific legal
stipulations.
The connection of a solar installation, an electric
heating rod or an alternative heat generator may
cause the storage temperature to exceed 60 °C.
● For this reason you should fit scalding
protection (e.g. VTA32 + Screw connection
set 1") during installation.
● Use a pressure reducer if the cold water
connection
pressure >6 bar.
If the Daikin EKHWP / EKHWC / EKHWD is
connected to a heating system with steel pipes,
radiators or non-diffusion-proof floor heating
pipes, slurry and swarf could enter the hot water
storage tank and cause blockages, local
overheating or corrosion.
● To prevent possible damage, fit a dirt filter or
sludge separator into the heating return flow
of the system.
