VAPORSTREAM INSTALLATION, OPERATION, AND MAINTENANCE MANUAL
FIGURE 2-1: VAPORSTREAM SYSTEM EXAMPLE, TAP/SOFTENED WATER
Product overview
TAP/SOFTENED WATER
Vaporstream humidifiers with tap/softened water (shown above) use electricity
to heat tap or softened fill water into steam for humidification. A conductivity
probe monitors the water level; therefore, water conductivity must be at least
30 μS/cm for proper operation. Vaporstream with tap/softened water will not
operate with RO/DI water. For RO/DI water, use Vaporstream with the RO/DI
water option.
RO/DI WATER OPTION
Vaporstream humidifiers with RO/DI water systems (systems using deionized
water or water that has been treated using reverse osmosis) use electricity to
heat RO/DI fill water into steam for humidification. Water level is controlled
with a float valve and low water cutoff switch. Float valves are compatible with
RO/DI water only.
Humidifiers with the RO/DI water option are virtually maintenance free and
require little or no downtime.

Supply water guidelines
Supply water quality is an important component
of humidifier reliability and maintenance.
Examples:
Corrosive water can decrease the service life
of the humidifier.
Excessive water hardness can increase the
humidifier maintenance requirements.
To maximize humidifier service life and
minimize humidifier maintenance, DriSteem
has established guidelines for supply water See
Table 2-1.
