The appliance is only intended to be installed and
operated in sealed unvented systems that comply with
EN 12828 / DIN 1988, or solar thermal systems that
comply with EN 12977, with due attention paid to the
associated installation, service and operating instruc-
tions. DHW cylinders are only designed to store and
heat water of potable water quality. Heating water buf-
fer cylinders are only designed to hold fill water of pot-
able water quality. Only operate solar collectors with
the heat transfer medium approved by the manufac-
turer.
Intended use presupposes that a fixed installation in
conjunction with permissible, system-specific compo-
nents has been carried out.
Commercial or industrial usage for a purpose other
than heating the building or DHW shall be deemed
inappropriate.
Any usage beyond this must be approved by the man-
ufacturer for the individual case.
Incorrect usage or operation of the appliance (e.g. the
appliance being opened by the system user) is prohibi-
ted and results in an exclusion of liability.
Incorrect usage also occurs if the components in the
system are modified from their intended use (e.g.
through direct DHW heating in the collector).
Adhere to statutory regulations, especially concerning
the hygiene of potable water.

Horizontal distribution of rafter flanges
A specific number of rafter flanges is allocated to each
number of collectors.
A specific number of rafters need to be used. This
number depends on the rafter spacing.
Example:
■2 collectors type SV
■Rafter spacing a 600 mm
■Snow load 0.75 N/m2
Look up the combination in the table for 2 collectors on
page 6 (highlighted grey):

Installation information
■The first and last collector must be positioned with
the type plate facing outwards (observe label).
■On just one of the collectors, fit the pipework at the
side opposite the type plate side.
!Please note
The connection pipes must be free of any signs
of damage.
Lubricate O-ring seals exclusively with the spe-
cial valve grease provided.

Installation information
■All pipes must be cut at a right angle and deburred.
■Lubricate all O-ring seals only with the special
grease provided.
■Initially turn the union nut by hand, then tighten with
an open ended spanner by a further ¾ turn.
■Never fit annealed copper pipes onto the locking
ring fittings.

Installation
!Please note
Incorrect installation can lead to collector dam-
age.
Use only gunmetal or brass fittings and copper
pipes for the installation.
Never step on collectors.
Never solder on or near collectors.
■Position pipes so that complete ventilation is
ensured. Install an air separator at an accessible
point in the pipework.
Note
An air separator is integrated into the flow line of the
Solar-Divicon (see diagram).
■Generally, copper lines in solar circuits are brazed or
joined by press fittings.
Soft solder could be weakened, particularly near the
collectors, due to the maximum temperatures that
may occur there. Metal seal connections, locking ring
fittings or Viessmann plug-in connections with double
O-rings are the most suitable.
Should alternative seals be used, such as flat gas-
kets, their manufacturer must give an assurance of
their adequate resistance to glycol, pressure and
temperature.
■Make all connections pressure and temperature-
resistant (observe the maximum stagnation tempera-
ture of the collector).
Never use:
–Teflon (inadequate glycol resistance)
–Hemp connections (insufficiently gas-tight)
Connecting the collectors (cont.)
5465 446 GB

■Equip systems to EN 12975 with an expansion ves-
sel, safety valve and circulation pump.
■The expansion vessel must be approved to DIN
4807.
The diaphragms and seals of the expansion vessel
and safety valve must be suitable for the heat trans-
fer medium.
To calculate the pre-charge pressure, see the
"Vitosol" service instructions.
■In the case of operation without Solar-Divicon, use
exclusively safety valves that meet the following con-
ditions:
–Designed for 120 °C and up to 6 bar (0.6 MPa)
–Letter ID "S" (solar) as part of the component iden-
tification
