Area Steam Distribution
TheEHF-3fanpackage(minimumof2requiredforHC-6500/6700)isdesignedtobehungonawall
to operate as a remote mounted, direct area discharge option. It incorporates a blower rated at 120v-
1.28 amps. CFM rating is 463 @ 1600 RPM. The fan package requires a separate 120 volt power sup-
ply(optionalstepdowntransformeravailable).ConsultArmstrongInstallationBulletinIB-95formore
information.
Alternative for shortened non-wettable vapor trail
For applications with particularly limited downstream absorption distance, Armstrong HumidiPack or
ExpressPack may be considered. HumidiPack is a prefabricated separator/header and multiple dis-
persion tube assembly. ExpressPack is a multi-tube steam dispersion panel which is shipped unas-
sembled. The Armstrong HumidiPack or ExpressPack provide uniform distribution and shortened non-
wetting vapor trail. Consult Armstrong Installation Bulletin No. 560 or Bulletin 573 for more information.
Control Wiring
When knock-out for sensor wiring is removed, an IP65 compliant cable bushing will be required to
keep the electric cabinet in compliance with IP32.
Wiring for low voltage controls should not be run in same conduit as the power supply. Use of shielded
wire or a separate dedicated metal conduit is required. When shielded cable is used, shield is to be
groundedatthehumidifieronly.Thewireshouldnotbelongerthan30meters(100ft).Ifthewireis
out of this limit, please contact Armstrong. Refer to Figures 10-1 and 10-2 for wiring schematics.
Control Humidistat
1. Locate control humidistat where it will sense the average air condition of the space to be
humidified. Avoid areas of restricted circulation or locations where the sensor will be
subjected to drafts, localized heat or moisture sources.
2. Optional duct mounted humidistats are available to sense return or exhaust air, if
preferred.
3. Set DIP switch S-2 on the PC board to the proper range for the humidistat control signal to be
used.SeeFigure9-1.AlsosetvoltagesourceDIPswitch(S1andS3)toproperrange.See 

series with duct pressure switch, if used, see Figure 10-1.
Airflow/Pressure Switch
An airflow switch is recommended to deactivate the humidifier when there is insufficient air flow in a
duct system. A duct pressure switch is preferred as an airflow sensor. The pressure switch should
openoninsufficientairflow(opensonfault).Airflowswitchshouldbemountedinsupplyairduct
upstream of humidifier dispersion. Remove the jumper tab from ground and in of high limit/pressure

Principle of Operation
The HumidiClean humidifier converts ordinary tap water or purified water to steam for distribution
to raise the relative humidity level. The demand for humidity is sensed by a humidistat or sensor
which sends a control signal to the HumidiClean. The HumidiClean is connected to the power
supply(208,220/240,380/400,480or600Vac)throughaseparatecircuitbreakersuppliedbythe
customer. When power is initially supplied to the unit from the circuit breaker, the LCD will display
“ARMSTRONG HC6000”. The “POWER” LED will come on and the unit’s fill valve solenoid is
energizedtoallowwatertoenterthetankatarateof1.2L/min(.31GPM)(HC-6500/6700fillrateis
3.735L/min(1GPM)).Note: When unit is turned on the drain valve will energize for 6 sec. or until
water level drops below the high water probe. If water level in tank is above the low water level
switch, assuming the air proving switch is close, the high limit humidity switch is closed and the unit
status is ‘STEAM GEN’, the heating elements will be activated.
The water fill solenoid continues to be activated until the water level in the tank has energized the
high water switch. Note: If fill or drain valves are not energized when power is first applied, check
LCD for diagnostic code. See DIAGNOSTICS section. The heating elements will remain on to preheat
the water inside the tank until the temperature of water has reached the aquastat set point. During
this preheat cycle the amperage draw of the tank can be checked with a clamp on amp meter. The
amperage draw on all high voltage wires connected to the main power supply terminal block should
correspond to the value on the nameplate. If aquastat has been disabled, the humidifier will go into a
3 minute warm-up once the water hits the low water probe.
After the heat-up time, the HumidiClean will continue to produce steam based on the demand signal,
read from the humidistat or calculated by reading the relative humidity and setpoint. If the demand
signaldropsbelow2%orthehighlimit/sailswitchcircuitopens,thecontactor(s)willopenandthe
unit status will be “IDLE”. Note: If the humidifier shuts off due to low humidistat demand, a demand
signalof4%orgreaterisneededtore-initiate“STEAMGEN.”Ifallthesignalsareconsistentasstated
above, HumidiClean will produce steam continuously and refill the tank with water when the low water
level is reached. These fill intervals will operate based on modulating fill settings in software.
Power to the heating elements is switched on and off by the triacs in the power module to achieve
a modulating output based on the demand signal. The triac utilizes a 1/2 second cycle time. For
example,witha50%humidistatdemandsignalthetriacswouldbeonfor1/4secondandofffor1/4
second. If the triacs are fully on, the green “SIGNAL” LED on the power module will be on constantly.
Whenthetriacsstarttomodulate(switchpowertotheheatingelementsonandoff)theLEDwillshow
the triac on condition and will appear to flicker or blink.
As HumidiClean continues to produce steam, the unit will accumulate and memorize the heating
elementactivetimeforthepurposeofdefiningadraincycleandservicelife(thismemoryisnot
affectedbypoweroutages).WhentheHumidiCleanheatingelementshavebeenonforthedrain
frequency setting, the unit activates the drain and fill solenoids and begins draining the tank. The tank
will drain with the water being tempered from an activated water fill solenoid. The drainage from the
tank will pass the low water switch, opening the switch and shutting off power to the heating elements.
Thedrainagefromthetankshouldnotexceed70°C(158°F).Thedraincycleiscontrolledbytheuser
inputted values in the operation setup menu. Once the unit has timed out of the drain cycle and all of
the switches are still in position to generate steam, the water fill solenoid switch is activated to fill the
tank and the cycle starts over again.

18
Maintenance
When90%ofthesettingservicetimehasaccumulated,the“STATE”LEDonthecontrolpanelwill
blinkinyellow.(RefertoEOLsettings,forbedlifedurationsettings).IftheHumidiCleanisnotserviced
atthistime;theunitwillcontinuetooperatefortheremaining10%oftheservicelifesetting.When
100%ofthebedlifesettinghasbeenreached,the“STATE” LED will be on in red. The unit will drain
the tank and not respond to a call for demand.
Note: Service Life can be adjusted based on water quality. If Ionic Beds are relatively free of scale
deposits or scale is forming on tank walls and elements because beds are saturated with scale, please
consult the factory for Service Life adjustment procedures.
