AWheeler surface condenserhas been installed in theapartment adjoining the en-gine room, as indicated inFig. 2. The city main bring-ing water to the storage tankis connected to the condens-er so that the latter is inter-posed in the line of the main,and all water passes throughthe condenser on its way tothe storage tank.
