Notes on Installation
H The entire solar heating sys tem
should be inst alled in accordance with
the accepted rules of technology,
observing all relevant accident
prevention regulations.
H Employ suitable safety measures to
prevent falls, falling objects and roof
damage due to insufficient load
bearing capacity, e.g. by means of
scaffolding, ladders, cable ties etc.
H The c ollectors must be securely
mounted so that the mountings can
withstand intense wind conditions.
H Use only stainless steel screws and
bolts when fastening mounting
brackets or frames.
H Although the glass collectors surfaces
are hail-proof, Viessmann recomends
users to include storm coverage in
their building insurance. Our warranty
does not cover s torm related damage.
H The collectors should, as far as
possible, be oriented towards the
south. Solar system performance
drops off significantly if collectors
face more than 50° off south.
H The collectors should be mounted
level, or with a slight ascending slope
(approx. ½” / 10mm) towards the
high point of the piping, so that
complete venting is assured.
H An air vent v alve (c/w shut-off valve)
should be installed at the highest
point of the solar heating system.
H Filling the s olar heating system with
Viessmann heat transfer fluid
“Tyfocor-HTL” is highly
recommended. Tyfocor-HTL is
supplied pre-mixed and water must
not be added.
Other heat transfer fluids may be
suitable if they have the same
temperature range (-35°C to 170°C)
and are non-toxic.
H The piping inside and outside the
building should be insulated to avoid
heat loss. Use only high temperature
resistant pipe insulation.
Collector Location
Please refer to the Vitosol System Design Guidelines, Part No. 5167 156 for detailed information on the optimum
alignment and inclination of solar collectors.
Optimum alignment and inclination
The solar collector provides the highest
solar yield over an annual average when
facingsouthwithaninclinationof
approx. 30 to 45 degrees
to the horizontal plane. However, the
installation of a solar heating sy stem is
still viable even when the installation
deviates quite significantly from the
above (south-westerly to south-easterly
alignment, 25 to 55 degrees
inclination).

Use only Viessmann supplied
mounting clips and mounting
hardware. N ever drill or screw
directly into collector side frames.
CAUTION
Poolwaterorpotablewatercannot
be pumped directly through the
Vitosol collectors. Damage to
collectors caused by corrosion, freeze
damage, or scaling will void warranty.
