Overview
Notes:
See Pages 8 and 9 for detailed installation
drawings.
Damage caused by chloride corrosion is not
covered by your DRI-STEEM warranty.
Tap/softened water
CRUV 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. CRUV with tap/softened water will not operate with
DI/RO water. For DI/RO water, use CRUV with the DI/RO water
option.
DI/RO water option
CRUV humidifiers with DI/RO water systems (systems using
deionized water or water that has been treated using reverse osmosis)
use electricity to heat DI/RO fill water into steam for humidification.
Water level is controlled with a float valve and low water cutoff
switch. Float valves are compatible with DI/RO water only.
Humidifiers with the DI/RO water option are virtually maintenance
free and require little or no downtime.
Water type conversion
CRUV tap/softened water humidifiers can be converted in the field
for use with DI/RO water, and CRUV DI/RO water humidifiers can
be converted in the field for use with tap/softened water. Contact
your DRI-STEEM representative or distributor for parts and
instructions.
