4.4 Water connection

CAUTION!
If the Daikin Altherma EHS(X/H) is con-
nected 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 over-
heating or corrosion.
Flush the feed pipes before filling the
heat exchanger.
Rinse out the heat distribution
network (in the existing heating
system).
Install the dirt filter or sludge
separator into the heating return flow
(see chapter 2.4.6).
CAUTION!
If the Daikin Altherma EHS(X/H) is con-
nected to a cold water line, where steel
pipes are used, chips can enter the
special steel corrugated pipe heat ex-
changer and remain there. This can lead
to contact corrosion damage and sub-
sequently to leakage.
Flush the feed pipes before filling the
heat exchanger.
Install contamination filter in the cold
water feed (see chapter 2.4.6).
Only Daikin Altherma EHS(X/H)B...
CAUTION!
If the heat exchanger for charging the
pressurised solar system (fig. 4-1 /
fig. 4-2, item 8+9) has an external
heating unit (e.g. wood-burning boiler)
connected to it, an excessive flow tem-
perature at these connections can
damage or destroy the Daikin Altherma
EHS(X/H) B.
The feed flow temperature of the
external heater should be limited to
max. 95 °C.
