VAPOR-LOGIC
®
VERSION 6 INSTALLATION AND OPERATION MANUAL
Automatic drain sequence, all water types
Vapor-logic uses an automatic drain sequence (ADS) to reduce mineral
accumulation in the tank and drain line which decreases tank maintenance .
Automatic draining and flushing parameters are defined in the water
management section of the Settings menu:
• First, automatic draining and flushing must be enabled .
• Second, the amount of water converted to steam (Usage) before an
automatic drain sequence begins must be defined in Settings/Water
Management/Automatic Drain Sequence .
• With a
Smart Drain
interval type, Vapor-logic will dynamically change
the usage between drains depending on detected water quality . This
allows for less frequent drains for clean water and more frequent drains
for water with many dissolved solids . (Smart Drain is the default usage
choice) .
• With a
Static
interval Vapor-logic always uses the same usage interval .
The default value is model-specific and calculated based operating 100
hours at 100% capacity . The user can change the usage value to get
more or less frequent drains .
• Third, days of the week when the automatic drain sequence can occur
must be defined . This means that once the Usage requirement is met, the
automatic drain sequence can occur on the first allowed day (allowed days
default is all days) .
• Last, time of day when the automatic drain sequence occurs must be
defined (default value is midnight) .
For example, if you use factory static default settings for the automatic drain
sequence, the first automatic drain sequence will occur at midnight on any
day of the week once the model-specific usage requirement has been met . If
you want to change these settings, go to the water management section of the
Settings menu .
For RO/DI water DriSteem recommends enabling the automatic drain sequence
with the Smart Drain option . The humidifier will drain very infrequently but just
enough to protect the tank from aggressive water .
Sequence of operation for the automatic drain sequence: ADS starts by
opening the drain valve to empty the tank . When the drain duration ends, the
fill and drain valves remain open to flush the tank . When the flush duration
ends, the automatic drain sequence is complete and the humidifier resumes
normal operation . During all of these actions the home screen will display a
tank status of “Auto Drain” . The default drain and flush durations are model-
specific and can be adjusted in the water management section of the Settings
menu .
