Safety instructions
Please follow these safety instructions closely to prevent
accidents and material losses.
Installation, commissioning, inspection, maintenance and repairs
must only be carried out by a competent person (heat- ing
engineer/installation contractor).
Before working on the equipment/heat- ing system, isolate the power
supply (e.g. by removing a separate mains fuse or by means of a
main isolator) and safe- guard against unauthorised reconnec-
tion.
Repairing components that fulfil a safety function can compromise
the safe oper- ation of your heating system. For replacements, use
only original spare parts supplied or approved by Viessmann.
Application
For retrofitting solar thermal systems in existing heating
systems.
Comprising the following components: Solar-Divicon SR with
Vitosolic 100,
type SD1 solar control unit Connection set for connection to
the
retrofit cylinder
240
B Non-return valve in the flow and return pipes
C Pre-assembled and sealed valves and the safety assembly with
pres- sure gauge
D Circulation pump E Fill and flushing unit F Flow indicator
System examples
There are 2 methods of control: Version A:
Transfer with sensor S3 in DHW cylin- der 2 (existing) Differential
temperature control
Version B: Transfer with sensor S3 in DHW cylin- der 1 (retrofit)
Control via thermostat function
If it is possible to position the tempera- ture sensor for the DHW
circulation diversion in the existing cylinder, we rec- ommend
version A.

Installation information
Always install the Solar-Divicon so as to prevent steam from
entering the expansion vessel in the event of stag- nation.
The Solar-Divicon is unsuitable for direct contact with swimming
pool water.
Every time the system is drained, flush the system with heat
transfer medium.
Install a thermal insulation loop if the expansion vessel is
installed as high as or higher than the Solar-Divicon.
System examples (cont.)

Use only gunmetal, brass fittings, cop- per pipes or Viessmann
stainless steel solar circuit pipes for the installation.
Use hemp only in conjunction with pressure and
temperature-resistant sealants (e.g. Viskotex solar paste from
Locher, CH-9450 Altstätten).
Check the sealing faces for cleanli- ness and damage before
assembly.
Installation of the locking ring fittings
All pipes must be cut at right angles and deburred.
Initially turn the union nut by hand, then tighten with an
open-ended span- ner by a further ¾ turn.
Never fit annealed copper pipes onto the locking ring
fittings.

Installation with copper pipes Insert the support sleeves into the
solar circuit pipe and secure with valve connections.
Installation with stainless steel solar circuit pipe Trim and
deburr in the valley of the corrugation; do not damage the peak of
the corrugation.
Fit the union nut, half washer (in the fifth valley) and guide ring
(in the sec- ond valley) and O-rings (in the first and third
valley).

The expansion vessel can be connected either to the flow or the
return. Connec- tion to the return is standard. When con- necting
to the flow, a smaller expansion vessel may possibly be selected.
Observe the sizing according to the tech- nical guide or the
Viessmann calculation program.
Installation with copper pipes Insert the support sleeves into the
solar circuit pipe and secure with valve connections.
Installation with stainless steel solar circuit pipe Trim and
deburr in the valley of the corrugation; do not damage the peak of
the corrugation. Fit the union nut, half washer (in the fifth
valley) and guide ring (in the sec- ond valley) and O-rings (in the
first and third valley).
Secure the discharge pipe with safety valve A of the safety
assembly on site. Place a drip pan underneath (liq- uid seal must
be equal to the liquid content of the collectors).
Discharge pipe: – Up to 2 m pipe length, minimum pipe
diameter 20 mm – Up to 4 m pipe length, minimum pipe
diameter 25 mm, up to 2 pipe bends
