professional, who must take into
account the prevailing conditions on
site.
HApplicability
Vitosol solar collectors are designed
for use in closed loop heating systems
for domestic hot water heating, space
heating and pool heating via a heat
exchanger. The use of Viessmann
heat transfer medium “Tyfocor-HTL”
is strongly recommended.
Other heat transfer fluids may be
suitable if they have the same
temperature range (-35°C to 170°C)
and are non-toxic.
Pool water or potable water cannot be
pumped directly through the Vitosol
collectors. Damage to collectors caused
by corrosion or scaling will void
warranty.
5285 771 v1.1
Observe maximum load and distance
from edge before installing the
substructure to the roof. If necessary,
consult with a structural engineer to
determine if the structure is suitable
for installing solar collectors. The
collectors must be securely mounted
so that the mountings can withstand
intense wind conditions and local
snow loads.
CAUTION
Gloves and eye protection must be
worn when handling solar panels.
CAUTION
Solar panel connection pipes and
solar heating fluid can become hot
enough to cause severe burns.
Extreme caution must be taken if
panels have been in a stagnant
condition (no flow of fluid).
CAUTION
Avoid scratching or sudden shocks to
glass cover of the solar panel.
CAUTION
Never step on collectors or solder in
close proximity to the glass surface
of the solar panel.

Procedure
1. Flush, leak test and fill solar heating system
Service
Start-up
All work on the solar circuit or the components of the solar heating system may only be carried out if the sky is very
cloudy, early in the morning, in the evening or with covered collectors.
We recommend the system is only flushed with the specified heat transfer medium to prevent a mixing with residual
water inside the system. Mixing would alter the level of frost protection.
HHeat transfer media containing glycol
can be damaged if they are subjected
to temperatures above 170°F / 77°C
for a prolonged period of time
(stagnation).
This can lead to the system suffering
from sludge and hard deposits,
particularly in conjunction with other
contaminants.
HEnsure that the system is correctly
flushed, filled and vented after
installation. After filling the system
with heat transfer medium, ensure the
system is correctly vented and that
heat is transferred inside the system,
i.e. that longer periods of stagnation
are avoided.
HThe blow-off and drain pipes should
terminate in an open container
capable of holding the maximum
possible collector fluid volume.
1. Cover up collectors, if necessary.
2. Manually open any installed isolation
valves.
3. Open the flow check valves on Solar
Divicon on the supply and return lines
by:
HTurning the thermometers counter
clockwise 45°.
4. Close the shut-off valve on the
system fill manifold Iandopenthe
drain valve .
5. The system is flushed via the return
line to the collector.
Fill and flush the system with heat
transfer medium via the filling valve
.
Flush using a quick-running pump
until you can be sure that all air has
been purged from the solar panel
system. Proper start-up can only be
guaranteed with a system that is
completely free of air.
6. Close the drain valve on the
system fill manifold. Continue to
charge system until desired cold fill
pressure is achieved, then close .
Open the shut-off valve and
check the system for leaks.
Observe the permissible operating
pressure. The pressure should not
drop over the space of at least one
hour.
5285 771 v1.1
Never mix Tyfocor HTL with alternative
heat transfer media or with water.
CAUTION
Never flush with water when it is
freezing, if no heat transfer medium is
used.
CAUTION
Never drain the system with a vacuum
pump.

Service
Maintenance
The collectors must be covered before
any work on the components of the
solar heating system begins, in order to
prevent equipment damage.
Isolate the main power supply of the
system (e.g. by unplugging the control
system or by means of a main power
disconnect switch) and safeguard
against unauthorized and/or accidental
reactivation.
3. Clean collectors
Service
Maintenance
In areas experiencing frequent rain,
collector cleaning is not usually
required. In areas with very dry
climates, urban areas or dusty areas,
check and clean collectors periodically.
Use a soap and water solution and flush
thoroughly with water.
4. Check gaskets and sealed unions

5. Check the thermal pipework insulation
Service
Inspection and Maintenance
Check the thermal insulation of the
pipework for damage and fit. No bare
metal or fiberglass insulation should be
exposed. Adjust if necessary.
Replace all worn/faulty parts.
The thermal insulation*1 of external
pipework must be resistant to
temperature, water and UV radiation. It
must be protected against destruction
by vermin and birds (e.g. metal casing).

1. Drain the system until the pressure
gage indicates 0, or isolate the
expansion tank from the system and
reduce the pressure at the expansion
tank connection.
2. If the air cushion charge pressure of
the diaphragm expansion tank is
lower than the set system fluid
pressure value, top up with sufficient
nitrogen to raise the charge pressure
to match the set fluid pressure.
Set air cushion charge pressure of
the expansion tank using this
formula:
22 psig+0.45xstatic head in ft
(1.5bar+0.1xstatic head in m)
Static head (collector top edge to the
expansion tank) = ft / m
=22psig+0.45x ft=psig
