Installation
8.1
Before connecting
NOTE:
Adherence to these specifications is a prerequisite for
the upholding of warranty claims.
Please refer to the current technical documentation for de-
tailed technical information on designing and planning a
system with SOLUS II storage tanks.
8.1.1
Heating, water quality
Use the storage tank in closed heating systems only. In
heating circuits which are not 100% sealed - e.g. plas-
tic underfloor heating systems -, a hydraulic separation
of storage tank and heating circuits is required to pro-
tect against oxygen which is diffused into the heating
water.
Please ensure that you comply with the instructions on
water quality in the technical documentation (no addi-
tion of substances to the heating water; if necessary,
sludge separators or filters must be fitted).
8.1.2
Hot water pipelines, water quality
The heat exchangers in SOLUS II storage tanks are made
of copper. The pipes connected to them should therefore
also be made of copper, stainless steel or plastic to prevent
corrosion of the pipes (see "Mixed installation" in the tech-
nical documentation). The water quality regulations for
copper piping must be observed (see water quality, tech.
documentation).
8.1.3
Solar pipes, solar fluid
For solar piping, we recommend copper pipes due to the
low resistance and the low heat loss compared with
stainless steel corrugated pipes. Consolar high-
performance collectors make greater demands of the tem-
perature resistance of the lines, which is why Consolar
recommends IsoConnect HT Cu.
Do not use larger pipe diameters than necessary, as oth-
erwise heat losses rise sharply. See "Technical Data" in the
technical documentation for recommended guideline val-
ues.
Use antifreeze approved for solar power systems based on
propylene glycol in the prescribed mix ratio only. We rec-
ommend Tyfocor LS (ready mixed) which can be pur-
chased from Consolar. The antifreeze must be checked
regularly in accordance with the regulations (see also the
technical documentation for CON-SOLARSTATION and
"Acceptance and maintenance protocol").
8.1.4
Pipe insulation:
The insulation of the pipelines has a major influence on the
energy savings which can be achieved with the solar
power system. It is therefore recommended to use consid-
erably thicker insulation on all pipes (solar, hot water,
heating pipes) than is required in accordance with the
German Heating System Ordinance (HZAnlV), e.g. with
125 % to 150 % instead of 100 % insulation thickness.
8.1.5
Space requirements
Install the storage tanks so that they can be accessed for
maintenance, to guarantee access to temperature sensors
and connections. This allows the insulation to be attached
and adjusted even after the system has been connected. If
the ceiling is low, the lid insulation can be fitted while the
tank is tilted and before it is positioned on the feet. To save
space, the lid insulation and the cover can also be sepa-
rated.
8.2
Transport
The storage tank must always be kept upright during trans-
port!
It can be transported horizontally by hand. Heavy vibra-
tion and impact should be avoided.
8.3
Storage
SOLUS II storage tanks may only be stored and installed in
rooms protected against frost.
8.4
Installation
Installation and commissioning may only be realised by
a specialist company approved by the local water sup-
ply company. This specialist company thus assumes re-
sponsibility for correct fitting work.
Contact with materials (e.g. some solvents) which can
affect the polystyrene or other components of the stor-
age tank is to be avoided.
When installing and operating the SOLUS II storage
tank, keep a minimum distance of 0.5 m from hot ob-
jects (>90 °C) (e.g. stovepipes, brazing torchs).
Place the storage tank on the plastic feet before you
start fitting the piping (except SOLUS II 2200 L).
To do so, refit the bolts which held the storage tank on
the wooden pallet. Insert the 3 plastic feet from beneath
into the bolt heads.
