Solar storage tank with heating controller

2.4.3 Site of installation
For safe and fault-free operation, the installation
location of the Daikin Altherma M ECH
2
O must
meet certain criteria. Information on this can be
found in chap.
4.2.
Information on the installation site of other com-
ponents can be found in the associated docu-
mentation supplied with them.
2.4.4 Heating system and sanitary
connection
The domestic water quality must comply
with the EU Guideline 98/83
EC and the
regionaly-applicable regulations.
●
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
regulations.
The connection of a solar installation, an electric
heating rod or an alternative heat generator may
cause the storage temperature to exceed 60
°C.
●
Scalding protection (e.g. VTA32 + Screw
set
1") must therefore be fitted during instal-
lation.
If the Daikin Altherma M ECH
2
O is connected to
a heating system with steel pipes, radiators or
non-diffusion-proof floor heating pipes, sludge
and swarf can enter the hot water storage tank
and cause blockages, local overheating or
corrosion damage.
●
To prevent possible damage, fit a dirt filter or
sludge separator into the heating return flow
of the system.
– SAS

●
The dirt filter must be cleaned at regular
intervals.
2.4.5 Demands on the heating and pressure-
free storage water
Observe the relevant regulations of technology
to prevent creation of corrosion products and de-
posits.
Minimum requirements regarding the quality
of filling and supplementary water:
– Water hardness (calcium and magnesium,
calculated as calcium carbonate):
≤
3 mmol/l
– Conductivity:
≤
1500
(ideal:
≤
100)
μ
S/cm
– Chloride:
≤
250
mg/l
– Sulphate:
≤
250
mg/l
– pH-values (heating water): 6.5 - 8.5
Using filling water and top-up water which does
not meet the stated quality requirements can
cause a considerably reduced service life of the
equipment. The responsibility for this lies solely
with the operator.
2.4.6 Operation
The Daikin Altherma M ECH
2
O:
●
Do not operate until all installation and
connection work is completed.
●
Only operate with a completely full storage
tank (Level indicator) and heating circuit.
●
Operate at a maximum pressure of 3
bar.
●
Only connect with a pressure reducer on the
external water supply (supply line).
●
only operate if the protective cover is installed.
The specified servicing intervals should be
adhered to and inspection work must be car-
ried out.
2.4.7 Instruct the owner
●
Before you hand over the Daikin Altherma M
ECH
2
O, explain to the user how to operate
and check the system.
If a pressurised solar system or optional
external heat source is connected to the
system via the corrugated-tube heat ex-
changer (Bild
item
then these minimum requirements also
apply to the fill and top-up water for this
heating circuit.
