    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 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.

    Replacing the circulation pump

    1. Close shut-off valve F in the returnline (see page 3).

    2. Close shut-off valve H in the returnline: Use a screwdriver to turn the sloton the adjusting screw above the flowrate indicator to position "E".
