SPECIFICATIONS & DIMENSIONS
This humidifier is able to produce steam at various capacities depending on the voltage and current applied . The unit can be wired to use an input
voltage of 120, 208 or 240 Volts and input amperage can be set to 11 . 5 or 16 . 0 amps by changing a dip switch on the control circuit board (see
the ELECTRICAL POWER WIRING & SHUT OFF SWITCH section on page 10) . Configure the unit appropriately for the application (see TABLE 1 for
capacity specifications) .

WATER QUALITY
The Steam Humidifier is designed to operate on water with conductivity between 100 and 1,250 uS/cm . This correlates loosely with water hardness
between 3 and 36 grains/gallon . Water that is considered "hard" and softened water work well in the Steam Humidifier . The humidifier makes steam
when plumbed to low-conductivity water but it takes longer to reach nominal current .
As water in the canister boils and turns into steam, minerals are left behind . Minerals remaining in solution increase the conductivity of the water .
Minerals also deposit onto the submerged portions of the electrodes rendering those areas ineffective . As this occurs, the level of water in the canister
rises to expose uncoated electrode surface .
There are benefits and trade-offs to consider when the application allows a choice between hard and softened water:
Hard water: The benefit of hard water is less frequent draining and filling than with soft water, which results in better energy and water efficiency and
more consistent steam output . However, canister replacement could be more frequent with hard water, because mineral deposits coat the electrodes .
The harder the water, the more frequent the need for a new canister .
Softened water: The benefit of softened water is longer canister life (depending on water chemistry) than with hard water, because softened water
does not coat the electrodes nearly as much as hard water . However, softened water ions stay in solution to much higher concentrations than hard
water ions . This requires more frequent draining and filling, which results in lower energy efficiency, higher water consumption and less consistent
steam output .
