11.OPERATINGSEQUENCE
Once the Steam Humidifier has been installed and the
water, humidistat and blower interlock connections
completed,thehumidifiermaybeinitiallystarted.
A.Turn"ON"thewatersupplytothesteamHumidifier.
B.Setthehumidistattoahighor"ON"position.
C. Plug the S2000 Humidifier line cord into a 120
VAC,15ampsource.(240VAC,10ampforS2020).
D. The Green "POWER" LED should slowly blink
and the "FILL" LED should be illuminated. Water
should begin to fill the Water Pan. (If the unit is
equipped with an automatic drain valve, the "POWER"
LED will blink rapidly and the drain valve will open
momentarilyuponinitialstartup).
E. When the water has reached the probe level the
"FILL" lamp and fill valve will be turned off, and the
"HEATER" LED and heater element will be turned
on.
F. Once the water reaches 170 deg. F. the "BLOWER"
LEDwillilluminateandtheblowerwillturnon.
G. If the above steps have been successfully
completed,thehumidifierisoperatingproperly.
A. POWER: In normal standby mode, when the
humidistat is not calling for humidity and the power
cord is plugged in, the "POWER" LED should be
blinking slowly. If the green "POWER" LED is not
flashing, when there is power to the unit, there has been
amalfunctioninthemicroprocessorcircuit.
B. FILL: When the humidistat closes, on a call for
humidity, the "FILL" LED is illuminated, the Solenoid
Valve isopenandthewaterreservoirisfilling.
C. HEATER: When the water reaches it's proper level
the valve closes, the "FILL" LED goes out, the
"HEATER" LED is illuminated, and the Heater begins
toheatthewater.
NOTE: If the humidifier is unplugged while in
operation and then plugged back in, A rapid flashing
of the “POWER” LED will occur and all other
functions will stop! The unit wants to perform a probe
test but cannot perform this test until the water cools
down. Simply wait until the unit cools down and it will
resumenormaloperations.
D.BLOWER: Whenthewater in the reservoir reaches
approximately 170 deg. F. the "BLOWER" LED will
be illuminated and the interlock wiring should turn the
system blower on. Depending upon the water and
ambient temperatures, it may take anywhere from
fourto twelve minutes forthe water to heat to 170 deg.
F. If the humidistat remains closed the "HEATER" and
"BLOWER" LED's will both be illuminated at the same
timeandthe"POWER"LEDwillbeblinkingslowly.
E. The "FILL" LED will illuminate and the water
reservoir will refill at irregular intervals, depending on
the boil off rate. Depending upon the water
temperature, the "BLOWER" LED may remain
illuminated or maygo offwhenthe reservoir isfilling.
The "HEATER" LED should remain illuminated
unless the humidistat opens or the humidifier enters a
draincycleorfailuremode.
F. DRAIN: This LED will be illuminated when
the microprocessor cycles the humidifier into a
Maintenance Mode. This mode will last about one hour
and the microprocessor will automatically restart
the unit afterwards. This will occur once every twelve
hours to let the heater cool-down and contract so that
thermal expansion will shed any deposits that have
built up on the heater. If the unit is equipped with a
drain kit, the reservoir is drained of water and most
loose deposits. The drain valve will then close and the
fill valve will open to refill the reservoir and resume
normal operation. NOTE: The "POWER" LED will
blinkrapidlyduringMaintenancemode.
G. FAILURE LED'S: When service is required,
these LED's will illuminate. If the humidifier enters a
failure mode, it must be manually reset by
disconnecting the powerand then reconnectingit.
WATER: Thiswill occur when the reservoir is not
filling up with water, not filling fast enough or the
microprocessor cannot recognize that the water is
touchingtheprobe.
HEATER: This will occur if the humidifier is not
boilingoffenough waterduringthe "HEATER" cycle.
Water in reservoir is not reaching 170 deg. F.
temperature. Both LED’s will illuminate in this
condition.
THERMISTOR: This will occur if a short or open is
detectedinthetemperatureprobe.
NOTE:A unique featureof the “S”series humidifiers
iscalled“Fillon Request”. Theunitwillnotrefill with
water after a maintenance cycle, unless there is a
demand for humidity from the humidistat. This
ensures that the unit will not sit idle with standing
water,whichcanstagnateovertime.
