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

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
