Product overview
Notes:
See Pages 14 and 15 for detailed installation
drawings.
Damage caused by chloride corrosion is not
covered by your DRI-STEEM warranty.
Supply water
XT electrode steam humidifiers use hard or softened supply water.
Water conductivity must be in the range of 125 to 1250 μS/cm
(roughly equivalent to 3.4 to 36.3 grains per gallon). See “Supply
water considerations” on Page 44.
Demineralized, deionized, and reverse-osmosis water cannot be
used, because they are not conductive enough for electrode steam
humidifiers.
Heated supply water cannot be used, because unheated supply water
is required for drain water tempering.
