CRUV Humidifier
This humidifier is designed to be used with either soft-
ened or unsoftened water (softened water will greatly
reduce humidifier maintenance and improve overall
system performance). The probe-type level control
system requires water conductivity of at least 100
micromhos/cm (2 grains/gal or 34.2 mg/1) to function, and
therefore, will not operate with demineralized water. For
humidification using demineralized water, see CRUV-DI
below.

CRUV-DI Humidifiers
The evaporating chamber of this humidifier is
constructed of corrosion-resistant stainless steel alloy
to resist the corrosive effects of mineral-free water.
Since the CRUV-DI humidifier is designed for use with
deionized or RO demineralized water, there is no need to
clean the unit, although an annual inspection of the
evaporating chamber is recommended.
