Safety instructions explained
Danger
This symbol warns against the risk of injury.
!Please note
This symbol warns against the risk of material
losses and environmental pollution.
Note
Details identified by the word "Note" contain additional
information.
Target group
These instructions are exclusively intended for quali-
fied contractors.
■Work on electrical equipment may only be carried
out by a qualified electrician.
■The system must be commissioned by the system
installer or a qualified person authorised by the
installer.
Regulations to be observed
■National installation regulations
■Statutory regulations for the prevention of accidents
■Statutory regulations for environmental protection
■Codes of practice of the relevant trade associations
■Relevant country-specific safety regulations
Working on the system
■Isolate the system from the power supply (e.g. by
removing the separate fuse or by means of a mains
isolator) and check that it is no longer live.
■Safeguard the system against reconnection.
!Please note
Electronic assemblies can be damaged by elec-
trostatic discharge.
Prior to commencing any work, touch earthed
objects such as heating or water pipes to dis-
charge static loads.
Danger
Hot surfaces can cause burns.
■Before maintenance and service work, switch
OFF the appliance and let it cool down.
■Never touch the hot surfaces of uninsulated
pipes and fittings.
Danger
Floors that are wet, damp or wetted with glycol
based liquids can cause injury due to slipping
and falling.
■Keep the floor clean and dry during installation
and maintenance work.
■Wear non-slip shoes.
Danger
Broken-off fragments of insulation material can
cause death by suffocation if inhaled or swal-
lowed.
■Do not let children play in the installation
room.
■Keep the installation room clean after installa-
tion and maintenance work.
Repair work
!Please note
Repairing components that fulfil a safety func-
tion can compromise the safe operation of the
system.
Replace faulty components only with genuine
Viessmann spare parts.

Auxiliary components, spare and wearing parts
!Please note
Spare and wearing parts that have not been tes-
ted together with the system can compromise its
function. Installing non-authorised components
and making non-approved modifications or con-
versions can compromise safety and may inva-
lidate our warranty.
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
pipes and lightly lubricate the threads with oil.
■Push the pipe into the locking ring fitting 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.

■The Solar-Divicon and the solar pump assembly are
unsuitable for direct contact with swimming pool
water.
■Every time the system is drained, flush the system
with heat transfer medium.
■A tee 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 ves-
sel is installed higher than the Solar-Divicon.
■Use only bronze, brass or stainless steel fittings,
copper or stainless steel pipes or Viessmann stain-
less steel solar circuit pipes for the installation.
Use hemp only in conjunction with pressure and tem-
perature-resistant sealants.
■Check the sealing faces for cleanliness and damage
before assembly.
■The discharge pipe must exit into an open container.

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 con-
trol unit at the factory.
See the solar control unit installation and service
instructions for further connections.
■Version without solar control unit:
Route the connecting cable for the circulation pump
downwards through the cable trunking and connect it
to the solar control unit.
See the solar control unit installation and service
instructions for further connections.

Systems with DHW heating:
A high limit safety cut-out (accessories) must be instal-
led on the DHW side. The high limit safety cut-out
must be set to 95 °C.
High limit safety cut-out installation instructions
Replacing the circulation pump
1. Close shut-off valve F in the return line (see
page 8).
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 run-
ning.
Note
The circulation pump
starts automatically after
the cause of the fault has
been removed.
■Undervoltage (< 160 V~)
■Overvoltage (> 253 V~)
Check the power supply.
(195 V~ < U < 253 V~)
Motor temperature too
high
Check ambient and heat
transfer medium tempera-
tures.
■Flashes red Circulation pump switched
off (blocked)
Circulation pump does not
start automatically.
Replace circulation pump
(see page 15)
■LED off —No power. Check connecting cable.
LED faulty Check whether the circula-
tion pump is running.
PCB faulty Replace the circulation
pump (see page 15).
