INSTALLATION OPTIONS AND EFFECT OF
wATER CHARACTERISTICS
Your Steam Humidifier can be powered with a 120, 208 or 240 volt circuit
and operated at either 11 .5 or 16 .0 amps . The higher the voltage and
amperage the higher the potential output . The operating voltage and
amperage are set by your installing contractor to meet the humidification
needs of your home .

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 have 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 HVAC system blower)
will allow it to reach rated capacity in the shortest amount of time .
Canister life is highly dependent on water quality . Canisters in systems
plumbed to water with high concentrations of suspended and dissolved
solids will not last as long as canisters operating on water with less
minerals .
NOTE: Amperage, Voltage and plumbing changes should be made by a
heating and air conditioning contractor .

OPERATINg MODES
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 168
hours of operation, 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, 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
level probe . At that point, the "Service" light will flash red indicating that
the canister should 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 valve will remain open
for 30 minutes . 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 .
