PIPINGCAUTIONCAUTIONThis drawing is to show the Vision contractor the correct installationguidelines. If the Vision 2 is applied to an installation that requires uniquepiping or wiring, it is recommended that you contact your local distributor.These drawings are for reference purpose only. It is important thatinstallers take special notice to the notes located under each drawing thathighlight important installation practices.Sensitive floor coverings shouldhave additional protection with theuse of limiting devices that willshutdown the circulators on thefeed lines to these floors, shouldthere be a failure.Munchkin Vision 1 & Vision 2 control systems4 individual space heating temperaturesPriority domestic water heatingDrawing V2-1Vision 2 valve actuator3-way mixing valve bodyREFER TONOTE 13mixedzone2mixedzone3REFER TO NOTE 13REFER TONOTE 13mixedzone4mixedzone1make-up d mixing valveDHWtemperaturesensor4 3 2 1Vision oilerVision 1 systemT/PP2purgeDHWzoneSuper Storindirect DHW tankthermal trap(w/ drain plug)condensatedrainNOTES:1.This drawing is meant to show system piping concept only.
