level probe. At that point, the “Service” light will flash red indicating that
the canister needs to be replaced. The humidifier will continue to operate
but with reduced output.
When the humidifier begins a drain cycle, the fill valve opens to introduce
cold water into the canister. This is done to prevent hot water from
entering the drain. The drain valve remains open for four minutes to allow
all water to drain from the canister.
Any time power is disconnected or humidifier is turned off, the internal
timer for start-up and drain cycles is reset.
If the humidifier has operated 168 hours without a drain cycle, the drain
valve will open and drain the canister. Normal operation will continue.
If the humidifier is operating and a power failure occurs, once power
is restored, the “On/Off” light will flash green for one minute, then the
humidifier will turn on.
END OF SEASON/PERIOD OF INACTIVITY SHUT-DOWN
If the humidifier does not receive a call to operate in 72 hours, the
humidifier controller drains the canister. The drain light will remain on until
there is a humidity call or 24 hours has elapsed. The humidifier will resume
normal operation when a call for humidity is made.
OPERATING MODES
DISPLAY PANEL
TABLE 1 – Display Panel
Indicator Light Function
Off
Humidifier is turned off or not receiving power.
Solid
Green
Humidifier is turned on.
Flashing
Green
Humidifier is preparing to turn on. Occurs if power is
disconnected, then restored with switch ON. Flashes
for one minute.
Solid
Green
Normal Operation. Fill valve is energized allowing
water to flow into canister via fill cup. (Does not
illuminate when tempering water during drain cycle.)
Flashing
Green
Fill and Drain Valves are pulsing to dislodge mineral
build-up in canister. Flashes 10 times in four seconds.
Solid
Red
Fault Mode. Indicates canister needs water but
cannot fill. Humidifier shuts down. (Occurs if high
water probe does not detect water after fill valve is
energized for 40 minutes.)
Your Steam Humidifier can be installed to operate using 120 Volts, 208
Volts or 240 Volts. The higher the voltage, the higher the potential output:
Voltage Rated Output
120 Volts 4 lbs./hour (11.5 gallons/day maximum)
208 Volts 7 lbs./hour (20.5 gallons/day maximum)
240 Volts 8 lbs./hour (23.3 gallons/day maximum)
It may take several days for the humidifier to reach rated capacity
depending on the input voltage and the electrical conductivity of
the water. 120 volt systems take longer to reach rated capacity than 240
volt systems. The humidifier should always be plumbed to cold water but
the water can be softened or unsoftened. “Hard” water, which has a high
mineral content, and softened water generally has higher conductivity than
naturally soft water. Systems plumbed to higher conductivity water will
reach capacity sooner than systems plumbed to low conductivity water. As
the humidifier operates, minerals build up in the canister, which increases
the conductivity of the water. With a new canister, allowing the humidifier
to operate continuously (along with the indoor unit blower) will allow it to
reach rated capacity in the shortest amount of time.
INSTALLATION OPTIONS AND EFFECT OF
WATER CHARACTERISTICS
When the humidifier is powered and turned on, the “On/Off” light is
illuminated green.
When the canister is being filled or replenished with water, the “Fill” light
illuminates green.
When the canister is being drained, the “Drain” light illuminates green.
During initial start up with a new canister, the humidifier may run through
a series of fill/drain cycles until the conductivity of the water is in a range
that allows normal operation. During this time, the “Steam” light illuminates
green. If the humidifier cannot produce steam at the rated level after trying
for 168 hours, the “Steam” light illuminates yellow. The humidifier continues
to operate in this state until the rated output is reached.
The conductivity of naturally soft water, hard water, and softened water
changes as the water heats up, but the internal controller adjusts the
water level to maintain a nominal current between the electrodes. Over
the life of the canister, minerals that build up on the electrodes will reduce
their effective surface area and affect the resistance between them. The
operating water level will increase with use until it reaches the high water
