The Armstrong HumidiClean humidifier converts ordinary tap water or purified water to steam
for distribution to raise the relative humidity level.
To allow HumidiClean to function to its full capability, be certain to install in accordance with
Armstrong recommendations.
DANGER: ELECTRICAL SHOCK HAZARD HIGH VOLTAGES EXIST INSIDE THE HUMIDIFIER
TO PROTECT YOURSELF AND OTHERS FROM ACCIDENTAL SHOCKS:
1. Keep the humidifier locked during normal operation and store the key in a safe location away
from the humidifier.
2. ALWAYS DISCONNECT THE POWER SUPPLY AT THE CIRCUIT BREAKER OR SAFETY
SWITCH BEFORE OPENING ANY COVERS AND DOORS!
3. Before servicing the humidifier, learn where the high voltage parts are. KEEP HANDS AND
METAL TOOLS AWAY FROM THESE AREAS!
Warning: All wiring and installation must be completed by qualified personnel
only and per the relevant local or national codes on electrical wiring. Negligence
of this warning might result in the loss of property or personal damage.
Warning: High Temperature! Material that is not resistant to high temperature
should not come in contact with these areas. Negligence of this warning might
result in the loss of property or personal damage.

Warning: Do not operate the supplied humidifier in combustible or explosive surroundings.
Warning: Do not operate the supplied humidifier if there is any damage to the cabinet or any
components in humidifier are damaged.
Warning: The main switch should be a connection breaker which has over current and leakage
current protecting functions per code EN60947-3 or EN60947-2 if point gap required by EN60947-3
can be fulfilled.

Pre-Installation
1. Check Shipment.Aclaimshouldbefiledwiththetransportationcompany,(andreportedto
 Armstrong),ifanyitemsaremissingordamaged.
2. Check Local Codes. The installation of HumidiClean should be in accordance with all applicable
building, plumbing, and electrical codes.
3. Site Selection. The humidifier should be installed in an easily accessible location. Do not install
the unit where malfunction of the humidifier might cause damage to non-repairable,
irreplaceable or priceless property. Refer to Installation section for other details regarding site
selection.

servicing.
1. Position wall mounting bracket level on wall and mark hole pattern. Make sure holes line up with
studs or other sturdy structure.
2. Use 3/8” x 1-1/2” lag screws provided to secure the bracket.
3. Hangthehumidifieronthewallmountingbracket.Thedryweightoftheunitis70kg(154lbs).
HC-6500/6700 Mounting

Consult factory if velocity is below recommended level.
3.Thedispersiontube(s)shouldbelocatedupstreamofastraightductrun,withoutobstructions,3m
(10feet)ormoreinlength.Consultthefactoryifthisdistanceisnotavailable.
4. Use the template provided to cut dispersion tube installation holes. Fasten the mounting plate to
ductwithsheetmetalscrews.Ifthedispersiontubeis900mm(35”)orlonger,supportthefar

5. Note:Forsteambeinggeneratedfromadeionized(DI)orreverseosmosis(RO)watersource,the
useof50mm(2”)insulatedstainlesssteelpipinginlieuofcopperisrequired.Pipeusedforsteam
dispersion piping must be oil and contaminate free. Premature element failure could result if oils or

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 
Fig. 9-1 for location of switches and pages 10 and 11 in tandem with the applicable wiring diagram
below for correct switch settings.
