Armstrong FLO-RITE-TEMP Instruções de instalação e ajuste

Single Wall Heat Exchanger - To remove the tube bundle for cleaning. Simply unbolt the mixing valve

from the shell and move it out of the way. The tube bundle can be pulled out from the valve end (see Table

12-1 for clearance dimensions). Once the tube bundle is out of the shell, unbolt the end cap on the floating

head end and remove to provide straight through cleaning. Reassemble in the reverse order (On the Model

665 dual stem unit when reassembling the tube bundle, make sure that the "TOP" indicator stamped on the

cover and both ends of the tube bundle line up and bundle is reinstalled in the shell with both "TOP" indicators

facing up). New gaskets will be required for this procedure. (Order heat exchanger gasket kit for model

number)
