VAPOR-LOGIC
®
VERSION 6 INSTALLATION AND OPERATION MANUAL
The Universal Water system allows the Vapor-logic controller to identify the
water type using a three-probe assembly . All water types and conductivities
work with the universal water system . The user does not need to select a new
water type or change hardware to change water types . Additional valves
and Vapor-logic algorithms measure and control the water level for optimum
efficiency and low water safety conditions . Vapor-logic automatically provides
a steady output while maintaining the water level between the bottom and
middle probes .
Water must remain in contact with the probe surface for three seconds for
Vapor-logic to determine that the water is at the probe’s level . Conversely,
water must stay out of contact with the probe surface for three seconds
for Vapor-logic to determine that the water is below the probe’s level . This
three-second delay ensures that turbulence does not cause an incorrect level
reading . If the water level falls below the low-water cutoff probe for a time
period determined by Vapor-logic, heating outputs are disabled; this provides
low-water protection for the heating outputs . If Vapor-logic detects water on
the top probe Vapor-logic will assume there is foam and a foam drain will start
immediately .
The humidifier will periodically perform probe checks to insure that the probes
are being read accurately and to determine the quality of the incoming water .
The humidifier status on the home screen will show “Probe Check” . After a
probe check the humidifier will adjust the Smart Drain usage interval used for
the automatic drain sequence . If the signal from the probe assembly begins
to deteriorate, the “Clean probes” or “Check Water Probe” message appears
in the Alert log . Once the probe system reaches its maximum usable life, the
humidifier shuts down and the user gets a “Faulty Water Probe” active alert .

CAUTION
Chloride corrosion
Damage caused by chloride corrosion
is not covered by your DriSteem
warranty .
Chloride corrosion can result from a
variety of causes, including, but not
limited to
• Improper water deionization
processes
• Improper water softening processes
• Humidifier’s supply water
