Partial Blow-Down
In order to dilute the concentration of the cylinder water, the con-
trol performs regular partial blow-downs.
Complete Blow-Down
Depending on water quality, a complete blow-down is done
every 3-8 days.
Power Surge - Blow-Down
At cold start-up, the nominal current increases to a maximum of
128% in order to achieve a rapid start-up. When this current
value is reached, a power surge blow-down is triggered and
performs partial drainage of the cylinder.
Dilution
The Dilution message is displayed if an additional partial blow-
down is required. This occurs for example at high conductivity
levels, with a significantly fluctuating control signal, or when
drainage is blocked.
6.1 Fault Messages (Comfort / Comfort Plus -
Control)
The Comfort / Comfort Plus - Control continuously monitors all
important functions of the steam humidifier. If the control detects
a fault, it turns off the steam generator.
To signal a fault, the red LED on the operation and display unit
blinks and a message appears on the display.
