Setting the temperature selector to high-
er settings provides hotter water, which
in creas es the risk of scald injury.
The manufacturer recommends the use of a prop er ly sized
thermostatic mixing valve to supply do mes tic hot water
at temperatures less than 140°F. Storing the water at a
higher temperature and ther mo stat i cal ly mixing the water
will increase the avail able quantity of mixed hot water,
greatly reduce the possibility of con den sate formation on the
heat exchanger and help pre vent the growth of water born
bacteria. Adequate care MUST be taken to prevent potential
scald injury when storing water at 140°F and hotter.
