Solar-Divicon and solar pump assembly
Safety instructions
Please follow these safety instructions closely to prevent accidents andmaterial losses.
Safety instructions explained
NoteDetails identified by the word "Note" con-tain additional information.
Installation, commissioning, inspection,maintenance and repairs must only becarried 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 fuseor by means of a main isolator) and safe-guard against unauthorised reconnec-tion.
Repairing components that fulfil a safetyfunction can compromise the safe oper-ation of your heating system. For replacements, use only originalspare parts supplied or approved byViessmann.

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

Fitting the Solar-Divicon
■ The Solar-Divicon and the solar pumpassembly are unsuitable for direct con-tact with swimming pool water.
■ Every time the system is drained, flushthe system with heat transfer medium.
■ A tee connection is available for thepurpose of connecting the expansionvessel and the stagnation heat sink inthe flow.
■ Install a thermal insulation loop if theexpansion vessel is installed higherthan the Solar-Divicon.
■ Use only bronze, brass or stainlesssteel fittings, copper or stainless steelpipes or Viessmann stainless steelsolar circuit pipes for the installation.Use hemp only in conjunction withpressure and temperature-resistantsealants.
■ Check the sealing faces for cleanli-ness and damage before assembly.
■ The discharge pipe must exit into anopen 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 tomake installation easier.If you are installing a Solar-Divicon, typePS20, remove the spring clip beforeremoving the flow and return lines.
Information on step 9:Versions:■ Installation with copper pipes
Insert the support sleeves into thesolar circuit pipes and secure withvalve connections.
■ Installation with stainless steelsolar circuit pipeTrim and deburr in the valley of thecorrugation; do not damage the peakof the corrugation.Fit the union nut, half washer (in the5th valley) and O-rings (in the 1st and3rd valley).
Information on the Solar-Divicon,type PS10 with solar control unitFor maintenance and service work, thesolar control unit can be hooked into theside of the circulation pump.
Electrical connections
■ Version with solar control unit:The circulation pump is connected tothe solar control unit at the factory.See the installation and serviceinstructions for further connections.
■ Version without solar control unit:Route the connecting cable for the cir-culation pump downwards through thecable trunking and connect it to thesolar control unit.See the installation and serviceinstructions for further connections.

Fault indications■ Flashes red and
green alternatelyCirculation pump isready for operationbut not running.
NoteThe circulationpump starts auto-matically after thecause of the faulthas been re-moved.
■ Undervoltage(< 160 V~)
■ Overvoltage(> 253 V~)
Check the powersupply. (195 V~ < U< 253 V~)
Motor temperaturetoo high
Check ambient andheat transfer medi-um temperatures.
■ Flashes red Circulation pumpswitched off(blocked)
Circulation pumpdoes not start auto-matically.
Replace circulationpump (seepage 11)
■ LED off — No operating volt-age.
Check connectingcable.
LED faulty Check whether thecirculation pump isrunning.
