Notes On Installation; Collector Location - Viessmann Vitosol 200-F Installation Instructions Manual

General Information

Notes on Installation

The entire solar heating system should be installed

in accordance with the accepted rules of technology,
observing all relevant accident prevention regulations.
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.
The collectors must be securely mounted so that the

mountings can withstand intense wind conditions.
CAUTION
Use only Viessmann supplied mounting clips and
mounting hardware. Never drill or screw directly into
collector side frames.
 Use only stainless steel screws and bolts when
fastening mounting brackets or frames.
 Although the glass collectors surfaces are hail-
resistant, Viessmann recommends users to include
storm coverage in their building insurance. Our
warranty does not cover storm related damage.
CAUTION
Pool water or potable water should not be pumped
directly through the Vitosol collectors. Damage to
collectors caused by corrosion, freeze damage or
scaling will void warranty.

Collector Location

Please refer to the Vitosol System Design
Guidelines, for detailed information on the
optimum alignment and inclination of solar
collectors.

Vitosol DHW Solar Pack Installation
The collectors should be mounted level so that

complete venting is assured.
Filling the solar 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 -31°F to 338°F
(-35°C to 170°C) and are non-toxic.
 In areas with extremely cold climate conditions,
where outside temperatures may drop below -31°F
(-35°C), the use of Tyfocor-HTL is not
recommended. Use a solar propylene glycol mixture
with a higher concentration of glycol that provides
the level of freeze protection required for the area of
the collector installation.
The piping inside and outside the building should

be insulated to avoid heat loss. Use only high
temperature resistant pipe insulation.
Optimum alignment and inclination
The solar collector provides the highest solar yield over
an annual average when facing due south with an
inclination of approximately 30º to 45º to the horizontal
plane.
However, the installation of a solar heating system
is still viable even when the installation deviates
quite significantly from the above (south-westerly to
south-easterly alignment with an inclination angle of
approximately 25º to 55º).
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
of due south.
