Safety instructions
Please follow these safety instructions closely to prevent accidents and
material losses.
Safety instructions explained
Note
Details identified by the word "Note" con-
tain additional information.
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.

Installing the locking ring fittings
■ All pipes must be cut at right angles
and deburred.
■ Insert support sleeves into pipework.
■ Push the union nut and the locking ring
onto the pipe and lightly lubricate the
threads with oil.
■ Push the pipe into the locking ring fit-
ting as far as it will go.
■ Initially tighten union nut by hand, then
tighten with an open-ended spanner
by a further ¾ revolution.
■Never fit annealed copper pipes onto
the locking ring fittings.

Fitting the Solar-Divicon
■ The Solar-Divicon and the solar pump
assembly are unsuitable for direct con-
tact with swimming pool water.
■ Every time the system is drained, flush
the system with heat transfer medium.
■ A tee connection is available for the
purpose of connecting the expansion
vessel and the stagnation heat sink in
the flow.
■ Install a thermal insulation loop if the
expansion vessel is installed higher
than the Solar-Divicon.
■ Use only bronze, brass or stainless
steel fittings, copper or stainless steel
pipes or Viessmann stainless steel
solar circuit pipes for the installation.
Use hemp only in conjunction with
pressure and temperature-resistant
sealants.
■ Check the sealing faces for cleanli-
ness and damage before assembly.
■ The discharge pipe must exit into an
open container.

Information on step 1:
After you have removed the upper insu-
lation shell, remove the transport protec-
tion cardboard.
Information on step 3:
Remove the flow and return lines to
make installation easier.
If you are installing a Solar-Divicon, type
PS20, remove the spring clip before
removing the flow and return lines.
Information on step 9:
Versions:
■Installation with copper pipes
Insert the support sleeves into the
solar circuit pipes 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
5th valley) and O-rings (in the 1st and
3rd valley).
Information on the Solar-Divicon,
type PS10 with solar control unit
For maintenance and service work, the
solar control unit can be hooked into the
side of the circulation pump.
Electrical connections
■Version with solar control unit:
The circulation pump is connected to
the solar control unit at the factory.
See the installation and service
instructions for further connections.
■Version without solar control unit:
Route the connecting cable for the cir-
culation pump downwards through the
cable trunking and connect it to the
solar control unit.
See the installation and service
instructions for further connections.

service instructions
Replacing the circulation pump
1. Close shut-off valve F in the return
line (see page 3).
2. Close shut-off valve H in the return
line: Use a screwdriver to turn the slot
on the adjusting screw above the flow
rate indicator to position "E".

Fault indications
■ Flashes red and
green alternately
Circulation pump is
ready for operation
but not running.
Note
The circulation
pump starts auto-
matically after the
cause of the fault
has been re-
moved.
■ Undervoltage
(< 160 V~)
■ Overvoltage
(> 253 V~)
Check the power
supply. (195 V~ < U
< 253 V~)
Motor temperature
too high
Check ambient and
heat transfer medi-
um temperatures.
■ Flashes red Circulation pump
switched off
(blocked)
Circulation pump
does not start auto-
matically.
Replace circulation
pump (see
page 11)
■ LED off — No operating volt-
age.
Check connecting
cable.
LED faulty Check whether the
circulation pump is
running.
PCB faulty Replace the circula-
tion pump (see
page 11).
